SECTION I

Understanding the Taber Abraser

INTRODUCTION

The Taber Rotary Platform Abraser Model 5135
and 5155 are durable, precision built test
instruments designed to evaluate the resistance
of surfaces to rubbing abrasion. Their field of
application is varied and includes tests of solid
materials, coated surfaces (paint, lacquer,
electroplated), plastics, textiles (ranging from
sheer silks to heavy upholstery), metals, leather,
rubber, linoleum, plus many others. In the
hands of a competent research technician, the
Abraser is capable of performing reproducible
tests, accurate within the variations of quality
inherent in the material itself.

axis of the sample. Figure 3 diagrams the

relative positions of the sample and abrading
wheels and the direction of their rotation.

One abrading wheel rubs the specimen outward
toward the periphery and the other, inward
toward the center. The resulting abrasion marks

(Figure 4) form a pattern of crossed arcs over

an area of approximately 30 cm
satisfactory for rating most materials.

),

PRODUCT DESCRIPTION

Characteristic rub-wear action of the Abraser is

produced by the contact of a test sample turning

on a vertical axis, against the sliding rotation of

two abrading wheels. The wheels are driven by

Figure 3

the sample in opposite directions about a
horizontal axis displaced tangentially from the

Figure 4

An exclusive and important feature of the 5135
and 5155 Abrasers is that the wheels traverse a
complete circle on the specimen surface,
revealing abrasion resistance at all angles
relative to the weave or grain of the material.

PRODUCT FEATURES

The Model 5135 and 5155 Abrasers have many
improved features compared to earlier versions
of the Taber Rotary Platform Abraser. These
are identified with an asterisk (*).

Operator Interface / Display*

The operator interface is an easy to use
membrane panel with tactile feel buttons and a
4-line digital display. Simple on-screen
instructions allow the operator to change the test
parameters and are accessed via the MENU

button. The following test parameters are
shown on the screen: test mode, test duration,
test cycles (completed or remaining), turntable
speed, and vacuum suction level (%).

60 / 72 RPM Turntable Rotation Speed*

Models 5135 and 5155 offer both 60 rpm and 72
rpm turntable rotation speed. This enables the
operator to select the speed referenced in the
test standard.

 NOTE: The turntable speed on previous versions of

the Taber Abraser was dependent on the electrical
line frequency. At 60Hz, the turntable speed was 72
rpm and at 50Hz the turntable speed was 60 rpm.

Preset Cycles Buttons*

The operator interface includes four commonly
used preset cycles buttons. This enables the
operator to automatically program 100, 500,
1000 or 2500 test cycles. The buttons may also
be used to “add to” the cycle count by the
corresponding incremental values.

Abrading Head Assemblies

Models 5135 and 5155 have independent
abrading arms of forged aluminum alloy that
pivot on ball bearings. The forward end of the

arm has a quick release wheel-mounting hub to
which the abrading wheel is mounted. The arms
are precision balanced to ensure exacting
results. Each arm applies 250 grams force
against the specimen with the wheel mounting
assembly in place (exclusive of the mass of the
wheels itself).

The outer end of the abrading head assembly
allows the auxiliary weight to be mounted
concentric with the abrading wheel. A stud on
the rear end of the abrading arm may be used to
carry a counterweight when it is desired to
reduce the wheel load to less than 250 grams
when testing delicate materials. It may also be
used to hold an abrading wheel as a
counterweight to compensate for the mass of
the working wheel.

Quick Release Mounting Hub*

An expanding collet hub design with push-button
operation permits quick wheel mounting, without
the need of a locking nut. A spring loaded,
beveled retaining nut provides a positive locking
force on the hub retaining lip making certain the
wheels remain securely fastened until
disengaged. The increased clearance results in
a larger viewing area of the test specimen.

4 5135 / 5155 Operating Instructions ver 1.1

Auxiliary Weights

Model 5135 has two pairs of precision stainless
steel weights of 250 grams and 750 grams
furnished with the testing set. In addition to the
mass of the abrading arm itself (250 grams) they
provide standard wheel loads of 500 and 1000

grams. Figures 6 – 9 show abrasers with

different loads applied (per wheel).

Available counterweights reduce the 250 gram

load to 125 grams or 75 grams (Figure 9).

Counterweights may be used in conjunction with
the standard weights to further expand the range
of wheel loads. To offset the weight of the
working wheels, wheels may be placed on the
counterweight-mounting studs.

 NOTE: For simplicity, each weight is marked with the

total load that will be exerted on the wheel.

Figure 9

Vacuum System

Models 5135 and 5155 include a vacuum unit
with a heavy-duty motor and life-lubricated
sealed bearings. With the vacuum power
connection plugged into the rear of the abraser
housing, the vacuum will be automatically turned
on when a test is commenced and shut off at the
end of the test cycles. A flexible rubber suction
hose connects it to the Abraser.

A vacuum pick-up nozzle is hinged to an
adjustable mount at the rear of the housing. The
height above the specimen is set by raising or
lowering the precision vacuum adjustment.

Figure 6

Figure 7

Precision Vacuum Nozzle Adjustment*

The height of the vacuum pickup nozzle is
adjusted by turning a knob. Each turn
represents 1.27 mm (0.05 inch) height adjustment,
making it significantly easier to set the proper
distance between the nozzle and specimen
surface. Located on the top of the instrument
next to the vacuum nozzle, the knob is easily
accessible.

Specimen Holder

The Model E100-125 specimen holder
accommodates most materials less than 6.35

(0.25 inch) thick with a 6.35 mm (0.25 inch)

mm
center hole. Rigid, flat specimens are secured
using the clamp plate and nut. For flexible
specimens, the E100-101 clamp ring is provided
in conjunction with the clamp plate and nut. An
S-19 rubber pad prevents specimens from
slipping during the test.

Specimen Holder Drive Shaft

The drive shaft for the specimen holder projects
vertically through the motor well in the Abraser
housing. Interchangeable specimen holders are
mounted to this shaft.

Figure 8

Accessory Receptacles

The Model 5135 and 5155 Abraser permit
control of the vacuum unit and an accessory
instrument (wheel refacer or grit feeder) from the
main unit. The electrical receptacles are
integrated in the rear of the housing and marked

accordingly (Figure 10). The use of the

electrical receptacles is restricted to the
specified equipment.

Figure 10

 NOTE: The power for the vacuum receptacle is

dependent on the voltage selector switch (115/230V).

power to either the Wheel Refacer or Grit
Feeder Attachment.

Through the MENU, you can choose to have
continuous power supplied to the receptacle or
ONLY while you test. When operating the
Wheel Refacer, select continuous power. This
allows you to reface wheels at any time,
provided the instrument is turned on. However
when operating the Grit Feeder, voltage should
be supplied ONLY when a test is being
conducted. This will enable you to coordinate

SPECIMEN SIZE

The width of the wear path is 12.7 mm (0.5 inch),
and located 31.75 mm
of the specimen. The size of the specimen may
vary depending on the material being evaluated.
For most rigid materials, a sample approximately
100 mm

(4.0 inch) square is recommended.

Flexible specimens are typically circular and
require the use of the clamp ring. If a mounting
card is used, the specimen should be
approximately 108 mm
no mounting card is used, a 135 mm
specimen is required such that the clamp ring
will grip the overlapped material.

If the specimen is less than the suggested size,
it is possible to position two or more specimens
on a mounting card to meet the size
requirement. If the edges are not flush together
or if the samples are of different thickness, the
edges may wear at a different rate than the rest
of the specimen.

The standard material thickness that can be
evaluated with the Taber Rotary Platform
Abraser is 6.35 mm
greater than 6.35 mm (0.25 inch) but less than

12.7 mm

(0.5 inch), the S-21 extension nut may

be used. Specimens with a thickness greater
than 12.7 mm

Mounting Sheets (S-37 and S-37-1)

These 108 mm (4.25 inch) sheets are coated on
both sides with pressure sensitive adhesive
overlaid with protective paper that is peeled off
just prior to use. Thinner than the S-36 and S­36-1, mounting sheets are used to provide a
non-slip attachment of the specimen to the
surface of the turntable and are especially useful
for materials difficult to drill a center hole (such
as glass or ceramics). Mounting sheets are
available as square (S-37) or round (S-37-1),
and have a test record printed on both sides
enabling them to be used as a mounting card.

SPECIMEN MOUNTING OPTIONS

To expand the versatility of the Taber Abraser,
mounting options and interchangeable specimen
tables are available to evaluate materials not
easily tested with the standard configuration. All
tables are engineered with a ball plunger and
drive pin spring clutch that locks the table onto
the motor shaft. This prevents the table from
shifting during a test, but allows for it to be easily
removed for specimen inspection or to clean the
motor shaft cavity. To gain access to the
specimen holder, lift the suction nozzle on its
hinge and raise the abrading arms up and back
beyond their balance point.

Mounting Cards (S-36 and S-36-1)

These 108 mm (4.25 inch) rigid cards are coated
on one side with pressure sensitive adhesive.
Designed to hold textile and other flexible test
specimens tightly to the mounting surface, they
prevent wrinkling while undergoing testing. A
test record form is printed on the backside of the
card for permanent record. Mounting cards are
available as square (S-36) or round (S-36-1).

Specimen Holder (E100-125)

The specimen table equipped with the Abraser
(E100-125) has been designed to accommodate
most materials less than 6.35 mm
thick. Unless optional accessories are utilized, a

6.35 mm (0.25 inch) center hole must be punched
or drilled in the specimen so it can be securely
fastened to the threaded center post.

To secure rigid materials, use the clamp plate
and nut. For flexible materials, also use the
supplied E100-101 specimen clamp ring. A 108
mm

(4.25 inch) diameter rubber pad (S-19) is

provided to ensure a non-slip surface.

Textile Specimen Holder – Tensioning
Type (E140-15)

Textile Holder – Tensioning Type for Wet
or Dry Testing (E140-18)

Similar to the standard specimen holder, the
E140-15 Tensioning Textile Specimen Holder
has a slightly raised wear track. This gives
textile and other flexible specimens additional
tension when the clamp ring is drawn down over
the edge of the holder and the clamp plate is
tightened in the center recess. Requires a 134
mm (5.25 inch) diameter specimen with a 6.35 mm

(0.25 inch) center hole. This holder is not

recommended for use with rigid specimens or
with mounting cards.

 NOTE: For proper mounting, place the specimen on

the holder and draw it taut with the clamp ring.
Tighten the ring, and then mount the clamp plate.

The E140-18 holder is designed to give an initial
stretch to woven fabrics so that they may be
tested while moist with minimum tendency to
wrinkle. A raised wear track provides additional

Drive Pin Type Holder (E140-19)

Threaded Ring Specimen Holder (E140-21)

The E140-19 Drive Pin Holder is intended for
rigid, square specimens that do not have a
center-mounting hole. The specimen is adhered
to the holder with S-37 or S-37-1 mounting
sheets and opposing driving pins prevent it from
slipping while the test is being conducted.

 NOTE: An example where this holder may be useful

is for glass or ceramic tile, which may be difficult to
drill a center hole.

The E140-21 Threaded Ring Specimen Holder
incorporates a clamp plate and flanged clamp
ring to test slightly warped, rigid specimens.
The ring is threaded to the body of the holder,
which securely clamps the outer edges of
specimens up to 137 mm

Specimen Holder with Transparent Base
(E100-10)

This Transparent Base Holder (E100-10) is
manufactured with a transparent base and
recommended to be used with the E100-102
clamp ring. When evaluating textile specimens,
the table may be removed from the Abraser to
view the abraded specimen against a strong
light source to determine the worn condition of
the threads. This eliminates the need to remove
the specimen from the holder permitting the test
to be continued if desired.

 NOTE: The vacuum is not used when conducting wet

tests.

 NOTE: This holder has also been used with a small,

high intensity light bulb located beneath the specimen
holder which activates a photocell and electronic relay
through the test material that turns off the Abraser
when the established wear point is reached.

ADJUSTING FOR OPTIMAL
PERFORMANCE

Selecting Abradant

Wear is a complex phenomenon and trying to
replicate it exactly in a laboratory setting can be
a challenge. There are numerous factors that
influence real-life wear, and identifying each
influence can be unwieldy. The ideal solution
would be to analyze the product in actual use,
however this could take months or years before
useful data becomes available. In addition, this
type of testing is often uncontrolled and costs
tend to be prohibitive.

Accelerated testing with the Taber Abraser is a
cost effective solution that provides a predictive
performance under a specified set of criteria.
While laboratory tests may not be 100%
representative of actual wear, established test
methods typically eliminate extraneous
variables, thereby enabling materials to be
evaluated using the same set of criteria.

The choice of which abrasive wheel to use with
your instrument is highly dependent on the
material that is being evaluated. Ideally, test
results should be correlated with field
observations. Many test methods specify which
genuine Taber abrasive wheel should be used.
If you are not following an established test
method, trial and error is suggested to help
determine whether one abrasive wheel is better
than another. Genuine Taber CS-10 and H-18
wheels are provided to assist with this
evaluation. It is often the case that materials
degrade faster with the more demanding
conditions of accelerated testing however as a
basic rule of thumb, a minimum number of test
cycles should be completed before the end point
occurs (i.e. 300 cycles). Otherwise, the
abradant may be too aggressive or the load is
too great.

beveled retaining nut provides a positive locking
force making certain the wheels remain securely
fastened. This eliminates the possibility of a
locking nut becoming loose during testing.

Figure 49

Genuine Taber abrading wheels are supplied in
pairs. A close inspection of the wheel labels will
show that one is marked “Left Hand”, while the

other is “Right Hand” (Figure 50). The purpose

of this is to assure that the mounting position of
the wheels will be duplicated when they have
been removed after use and later reinstalled.
The wheel labels should be facing inward.

Before preparing the wheels for testing, check
their condition and expiration date (if applicable).
Wheels that appear ‘out-of-round’ must be
refaced with the Wheel Refacer. Refer to
Refacing Calibrade Wheels on page 24.

Genuine Taber abrasive wheels are available in
a variety of standardized formulations. Each
offers unique features and provides a means to
precisely and effectively evaluate your material.
For additional information, see Characteristics of
Abrading Wheels on page 21.

 NOTE: To inquire about custom formulations, please

contact Taber Industries.

Mounting the Abrading Wheels

A feature of the model 5135 / 5155 is the Quick
Release Mounting Hub. Utilizing an expanding
collet hub, Genuine Taber wheels are quickly
mounted to the abraser. A spring loaded,

19 5135 / 5155 Operating Instructions ver 1.1

Figure 50

To mount a wheel, press the push button
located at the end of the auxiliary weight mount.
This will release the beveled retaining nut
enabling the collet to contract. With the label
facing toward the center of the turntable,
carefully slide the wheel all the way onto the
mounting hub. Release the push button. The
hub retaining lip will secure the wheel until it is
disengaged.

Periodic cleaning of the mounting hub and

flange with the S-12 brush is recommended to
prevent the accumulation of particles and other
debris. Any build up of loose debris may
prevent the wheel from being mounted properly.

 NOTE: When not in use, wheels should be stored in

their original containers to prevent damage.

Wheel Loading (Auxiliary Weights)

With no auxiliary weights, each abraser arm
applies a load of 250-grams against the
specimen. In addition to the mass of the
abrading arm itself (250 grams), precision
stainless steel weights are included to provide
standard wheel loads of both 500 and 1000
grams. For simplicity sake, each weight is
marked with the total load that will be exerted on
the wheel. The weights marked 500 grams are
actually 250 grams. Likewise, the weights
marked 1000 grams are 750 grams.

Counterweights are also available to further
expand the range of wheel loads, and may be
used in conjunction with the standard weights.
Available in 125 gram or 175 grams,
counterweights are applied to the mounting stud
found on the back of the abraser arm.

One of three standard wheel loads is normally
specified in the test method – 250 grams, 500
grams, or 1000 grams. This reference is per

arm (not combined), see Figures 6 – 9.

• When it is necessary to operate at less than
the 250-gram load, counterweights of 125
and 175 gram are available.

• To operate in the 250-gram range, no
additional weights are used.

Figure 51

 NOTE: The marking of the auxiliary weights indicates

the total of both the weight and the abrading arm.

 NOTE: The load that is specified in most test

methods does not include the mass of the wheel.

 NOTE: To eliminate the mass of the abrading wheels,

place a second pair of wheels on the counter weight
studs located on the rear of the abraser arms.

Lowering the Abrading Heads

Prior to conducting a test or refacing Genuine
Taber wheels, the abrading heads must be
lowered onto the surface of the specimen.
Firmly grip each arm and lower them from their
upright position.

When using the 5155 Abraser, if only one
turntable is utilized, the abrading arms not being
used should be raised to their upright position
and the vacuum nozzle not being used should
be in the down position.

• To operate in the 500-gram range, slide an
auxiliary weight marked 500 grams onto
both the left and right auxiliary weight
mounts (found opposite of the wheel
mounting assembly).

• To operate at 1000 grams, slide the auxiliary
weights marked 1000 grams onto the
auxiliary weight mounts.

If no wheel loading is specified in the test
method, an appropriate load may be determined
through experimentation. As a basic rule of
thumb, a minimum number of test cycles should
be completed before the end point occurs (i.e.
300 cycles). Otherwise, the load may be too
heavy. The section Characteristics of Abrading
Wheels found on page 21 provides additional
information should there be any load restrictions
for the abrading wheel you are using.

U WARNING: Dropping an abraser arm onto the

specimen table may cause misalignment and
consequent inaccurate test results.

Adjusting the Height of the Vacuum
Pickup Nozzle

After the specimen has been mounted, the gap
between the vacuum pickup nozzle and
specimen surface should be set. It is extremely
important that the height of the suction nozzle be
adjusted properly, especially when evaluating
specimens of different thicknesses.

Figure 53

The height of the vacuum pickup nozzle is
referenced in many test methods. If it is not, you
must consider the material being tested. For
most materials, a gap of 6.35 mm
sufficient. However, a setting of 3.17 mm

has been found to be more effective on

inch)

certain rigid materials.

To adjust the vacuum nozzle height, first lower
the vacuum pickup nozzle from its rest position.
A precision adjustment knob located next to the
nozzle is used to adjust the distance between
the nozzle and specimen. Each full rotation of
the knob represents a 1.27 mm

(0.25 inch) is

(0.125

(0.05 inch) height

adjustment.

 NOTE: To facilitate resetting the nozzle for a

given thickness of material, a shim may be inserted between
the nozzle and specimen, provided care is taken not to
damage the specimen surface.

Setting the Vacuum Level

The vacuum suction level should be set high
enough to remove debris from the specimen
surface, but not lift flexible samples. A visual
inspection of the wear path can usually indicate
if debris is adhering to the specimen surface and
the vacuum level (or vacuum pick-up nozzle
height) needs to be adjusted. For test control
and standardization of vacuum suction, the
vacuum level is calibrated to values of 50 –
100%.

Modified Vacuum Pick-up Nozzle

A modified vacuum pick-up nozzle is available
for materials that are evaluated using a change
in haze. It has been found that many materials,
such as transparent plastics, may generate
static electricity during testing resulting in an
attraction of loose grit and debris to the
specimen surface. The orifice openings of the
modified vacuum pick-up nozzle are 11 mm

(0.4375 inch) opposed to the nominal opening of 8

(0.3125 inch). This assists with the removal of

mm
debris that has adhered to the specimen as a
result of this static attraction.

If transparent materials are the only material that
you intend to test with your Taber Abraser, you
may elect to permanently modify the vacuum
pick-up nozzle (see below diagram).

CHARACTERISTICS OF ABRADING
WHEELS

The choice of which Genuine Taber abrading
wheels to use is best determined by preliminary
testing on the material to be investigated. The
abrasive action of the testing wheel should
reproduce, as nearly as possible, the wear that
the material will receive in actual use. It is
important to keep in mind that wear is a complex
phenomenon that may not be exactly replicated
through an accelerated abrasion tests.

Abrading wheels for the Taber Abraser can be
classified as:

®

Calibrase

resilient binder and aluminum oxide or silicon
carbide abrasive particles. Frequently used
to evaluate rigid specimens.

Calibrade

composed of a vitrified (clay) binder and
silicon carbide or aluminum oxide abrasive
particles. Frequently used to evaluate
flexible specimens.

Specialty – Used for special applications.

For both Calibrase and Calibrade wheels,
different grades are furnished to meet varying
requirements of abrasive action. During testing,
the wheel surface gradually wears away
exposing new abrasive particles. The minimum
usable diameter of Taber abrading wheels is 1­3/4 inch, which corresponds with the wheel
label.

The composition of Genuine Taber abrading
wheels has been carefully chosen to reproduce
normal service wear. The quality and uniformity
of these wheels is maintained by continuous
inspection sampling and tightly controlled
manufacturing processes.

®

– A non-resilient wheel

Calibrase Wheels

CS-10F Calibrase – A resilient wheel that offers

a mild abrading action, and was designed to
operate under loads of 250 or 500 grams. The
CS-10F is typically used to test materials such
as safety glazing materials and transparent
plastics, and must be refaced with the ST-11
refacing stone.

CS-10 Calibrase – Similar to the CS-10F, this

resilient wheel offers a mild – medium abrading
action like that of normal handling, cleaning, and
polishing. This popular wheel has been used to
evaluate a variety of materials including organic
coatings, plastics, textiles, leather and paper
products. Reface with the S-11 refacing disc.

CS-10P Calibrase – The abrasion rate is the

same as the CS-10, but this wheel has been
engineered so the wheel surface does not load
when testing paper products. Intended for tests
of short duration, with refacing after every tenth
test.

CS-10W Calibrase – This wheel is the same as

the CS-10 but white, to eliminate any color
transfer from the wheel to the specimen.

CS-17 Calibrase – Compared to the CS-10

wheel, the CS-17 produces a harsher abrasion.
Normally operated using loads of 500 or 1000
grams, this wheel is useful for testing materials
such as ceramics, plastics and enamels.
Reface with the S-11 refacing disc.

 NOTE: Custom formulations can be developed

specific to your application.

U WARNING: Because of possible deterioration,

Calibrase wheels should NOT be used after the
expiration date printed on the wheel.

 NOTE: The wear life of Calibrase or Calibrade

wheels will vary based on the load, surface texture
and frictional characteristics of the material tested and
frequency of refacing.

 NOTE: The abrasive coefficient of the wheels can be

altered by oil or other contaminants. Handle only the
sides of the wheels.

U WARNING: Shelf life is dependent on proper

storage conditions (temperature 23°C±2°, relative
humidity 50 ±5%). When not in use, store
abrading wheels in their original container.

Calibrade Wheels

Specialty Wheels / Abradants

H-10 Calibrade – A non-resilient, vitrified wheel

designed to evaluate steel and ferrous alloys for
resistance to abrasion. It has also been used, to
test the effect of hardening and tempering
treatment on steel and other ferrous materials.
The H-10 Calibrade wheel should be used with
either 500 or 1000 gram loading.

H-18 Calibrade – This commonly used non-

resilient wheel provides a medium coarse
abrasive action. It is most often used to
evaluate resilient materials such as rubber (non­tacky), certain woven textile fabrics, coated
fabrics, and flexible plastic sheets.

H-22 Calibrade – The H-22 wheel produces a

coarse abrasion. It has been used to test
rubber, linoleum, leather, deep pile fabrics (such
as automobile floor coverings) and concrete.

H-38 Calibrade – A non-resilient, vitrified

abrading wheel comprised of fine abrasive
particles. Designed to operate with 250 or 500
gram loads, the principal use of this wheel is to
test woven and non-woven fabrics. Must be
refaced using the Taber Wheel Refacer and
multi-point diamond tool.

Custom Formulations – To inquire about

custom wheel formulations, please contact
Taber Industries.

CS-0 – A resilient wheel containing no abrasive

particles. Intended for use when a very mild
abrasive action is required, or for wet tests such
as determining the relative abrasion of dental
pastes, cleaning powders, or similar
compounds. Adhesive sandpaper strips can be
adhered to the periphery of the CS-0 wheel to
evaluate the abrasion resistance of high­pressure decorative laminates.

 NOTE: Calibrade wheels do not have an expiration

period.

U WARNING: Calibrade wheels are diamond trued

at the factory and can be used continuously
without further refacing until the abrading
surfaces show indications of becoming worn out
of round, crowned or clogged. When refacing is
required, a wheel refacer must be used.

Figure 56

Figure 57

CS-5 – This abrading wheel is manufactured

from a densely compacted wool felt. Designed
to be tested at 250 or 500-gram loads, its
principal use is in testing textile fabrics when the
service wear requires one fibrous material to rub
against another.

Figure 58

23 5135 / 5155 Operating Instructions ver 1.1

S-32 – See CS-0.

S-35 – Manufactured out of tungsten carbide,

this periphery of the S-35 consists of sharp

helical teeth (1 mm pitch x 45° spiral pitch
angle). The teeth combine both a cutting and
tearing action, which provides a very severe
abrasion. Intended for use only on resilient
materials such as rubber, linoleum, and leather.

S-39 – This wheel is used in conjunction with the

Grit Feeder to conduct three-body abrasion
tests, and includes a leather strip that has been
adhered to exterior of a brass hub.

REFACING ABRADING WHEELS

Abrasion tests utilizing the Taber Abraser
require the abradant to be standardized prior to
the test. Failure to reface the wheel surfaces,
may introduce variation into the test results.
Depending on abradant type and material, the
wheel surface may change during the test (i.e.
become clogged) due to the pick up of debris or
other abraded material from the test specimen.
To standardize, the wheels must be cleaned
(refaced) at regularly defined intervals.

U WARNING: Wheels can be used until they are

worn down to their minimum diameter of 44.45 mm

(1.75 inch) O.D. as indicated by the wheel label.

Refacing Resilient Wheels (Calibrase)

The S-11 Refacing Disc (Figure 61) should be

used to resurface all Calibrase wheels with the
exception of the CS-10F. The CS-10F wheel
should be refaced using the fine side of a ST-11

Refacing Stone (Figure 62).

wheels. To maintain the rate of abrasion, the
sandpaper strips must be changed after a
defined number of test cycles (typically 200 or

500).

A. Breaking in New Wheels – Calibrase wheels

are diamond trued before leaving the factory,
however their resilient composition makes them
subject to slight changes of form. Before a new
pair of Calibrase wheels is put into service, the
wheels must be given two refacings of 50 cycles
each. This will break in the wheels, and ensure
perfect contact of the abrading faces with the
specimen surface.

Figure 63

 NOTE: The S-11 Refacing Disc is used only once

(maximum of 50 cycles), therefore this initial refacing
of new wheels will require two (2) Refacing Discs.

 NOTE: The useful life of the ST-11 Refacing Disc is

10,000 cycles (approximately 400 refacings).

U WARNING: Never reface wheels with a used S-11

refacing disc. Unless new S-11 refacing discs are
used for each refacing, the wear coefficient of the
wheel faces may change and inject an error in the
test results.

B. Testing with Previously Used Wheels –

Before each test, reface previously used wheels
25 or 50 cycles. Twenty-five cycles is sufficient
when the previous test was a short one on
similar test material. Fifty cycles is
recommended when the previous specimen was
of an unlike material or the test was of 1000
cycles or more.

 NOTE: Wheels that have not been used for a long

period of time may require two break-in refacings like
a new set of wheels.

C. Refacing Wheels During a Test – Calibrase

wheels are designed to operate continuously
throughout the test without additional refacing.
However, there may be times when the wheel
faces tend to become clogged due to the
adhesive character of particles worn off the
specimen. Should this happen, re-standardize
the abrading surfaces by running them 25
cycles, then proceed with the test. Do not
confuse coloring of the wheels with “clogging” as
this is simply due to the wheel faces becoming

coated with fine abradings, a condition that must
be expected.

 NOTE: For most materials, it is usually not necessary

to reface wheels prior to 1,000 cycles of testing. In an
extreme case it may be necessary to reface the
wheels every 500 cycles.

D. Truing Out-of-Round Wheels – It is

important that abrading wheels run true to obtain
accurate test results. Out-of-round wheels may
be detected by an up and down movement of
the abrading arm during testing. To reface
resilient Calibrase wheels when they become
worn out of round, follow the procedure for
refacing vitrified Calibrade wheels.

U WARNING: Truing Calibrase wheels on the

diamond refacer removes most of the abrasive
grain from the wheel faces. In order to re­establish their normal abrasion coefficient, they
must be given two refacings of 50 cycles each
(follow the procedure for breaking in new wheels).

Procedure for Refacing Calibrase Wheels

• Apply the wheels to the Abraser on the
corresponding quick-release mounting hub.
When facing the abraser, the right (left)
wheel will be mounted on the right (left)
abraser arm such that the wheel label is
facing inward towards the center of the
specimen table.

• Mount an S-11 Refacing Disc (ST-11
Refacing Stone) on the E100-125 specimen
holder. To secure the S-11, use the clamp
plate and nut, and clamp ring. The clamp
plate and clamp ring are not required for the
ST-11 refacing stone.

• Weight the abrading arm with the same load
weight that is to be used for testing.

• Lower the abrading wheels onto the refacing
medium.

• Lower the vacuum pick-up nozzle and adjust
its height to within 3.175 – 6.35 mm

0.25 inch)

below for CS-10F wheels.)

• If you are using a vacuum suction level less
than 100, program the appropriate value. It
is recommended that the vacuum level not
be less than 70 for wheel refacing.

• Program the appropriate number of cycles
according to Table 1.

• Using the S-12 Brush, frequently remove the
abradings by brushing the refacing medium
during the refacing operation. DO NOT
brush the wheels.

0.625 inch) above the ST-11 refacing stone.

 NOTE: Properly refaced wheels must contact the

specimen their full width. Refacing can be checked
visually, wheel color should be uniform after two
refacings of 50 cycles each. If it is not, reface the
wheels a third time.

U WARNING: Do not reface Calibrase wheels by

placing a S-11 refacing disc over the specimen.
Mounting on top of a specimen may cause the
surface of the S-11 not to run absolutely true,
which would abrade a slight crown on the wheel
faces causing inaccuracies.

Wear Characteristics of Calibrase Wheels

Resilient wheels possess properties that cause
the working faces to disintegrate slowly as they
are used, continually exposing fresh abrasive
grains to the specimen being tested. This
characteristic is necessary for the proper
functioning of the Abraser.

A thin film of rubber may form on the left hand
edge of Calibrase wheels as the main body of

the wheel wears down (Figure 64). Although a

narrow fin is not detrimental to the test, should it
extend more than 1.59 mm
the work surface, remove it by gently rubbing the
edge with your finger. Do not rub excessively so
as to round the edge of the wheel.

(0.0625 inch) beyond

Wear life of Calibrase wheels varies with the
surface texture and frictional characteristics of
the material tested, in addition to the load.
Under ordinary conditions Calibrase wheels
should give from 10,000 to 50,000 wear cycles.
Abnormally short wheel life indicates use of the
wrong wheel, load, or procedure for the material
tested, or too frequent refacing.

U WARNING: The abrasive coefficient of the

working faces of the wheels can be altered by oil
or moisture from the fingers. Touch only the sides
of wheels in handling.

Refacing Vitrified Wheels (Calibrade)

All Calibrade wheels are diamond trued at the
factory and may be used continuously without
further refacing until the abrading surfaces show
indications of becoming worn out of round,
crowned or clogged with abraded material.
Refacing is also advised when starting a series
of comparative tests or changing to an entirely
different material. In some instances, where
there is a tendency for the working surfaces of
the wheels to pick up excess material, it may be
desirable to reface the wheels before testing
each specimen. (This latter procedure is only
required in exceptional cases.)

A. Worn out of round

Procedure for Refacing Calibrase Wheels

To properly reface Calibrade wheels, a Taber
Wheel Refacer must be used. This instrument
utilizes a diamond tool that is traversed across
the working surface to precision dress the

abrading wheels (Figure 66).

Refacing Calibrade wheels leaves a sharp edge
that may sever threads when testing textile
fabrics. It is acceptable to remove this sharp
edge prior to testing. To do so, cut a small strip
from an S-11 refacing disc and hold it lightly
against the outer edge of each wheel. Manually
turn the nut to rotate the motor shaft. Reverse

the wheels on the arbor and round the opposite
corners. Only the extreme sharpness of the
edges should be removed. A radius of 0.4 mm

(0.016 inch) is sufficient.

SECTION II

Testing with the Taber Abraser

SIGNIFICANCE AND USE

The Taber Rotary Platform Abraser is commonly
used to provide comparative data regarding the
abrasion resistance of a material.

It is important to recognize there may be several
factors that contribute to wear performance of
materials in actual use. Before predictions can
be drawn from laboratory tests, actual end-use
trials should be conducted. This helps establish
the relationship between the laboratory abrasion
test and actual wear in the intended end-use.
The consideration of additional factors is often
necessary in the calculation of predicted
durability from specific abrasion data. While
“abrasion resistance” (often stated in terms of
the number of cycles to produce a specified
degree or amount of abrasion) and “durability”
(defined as the ability to withstand deterioration
or wearing out in use, including the effects of
abrasion) are frequently related, the relationship
typically varies with different end uses.

Accelerated abrasion tests compress the life
span of a product into a much shorter duration in
a controlled and monitored environment. While
the test may not represent the actual conditions
materials are exposed to, lab tests can duplicate
many real world conditions, making it much
easier to reproduce the test. In addition, there is
greater flexibility with the methodology, costs are
significantly less, and you are able to test more
samples.

TESTING PROCEDURES

As you start your testing, use of these guidelines
should assist you in developing a test procedure
that will yield reproducible test results, accurate
within the variations of quality inherent in the
material itself.

Establishing a Test Procedure

The purpose of this section is to outline all the
elements of a typical test procedure from
analysis of the testing problem to final evaluation
of results. Knowledge of the mere mechanics of
testing, the preparation and mounting of

specimens, and the setup and operation of the
Abraser is presumed. That phase of testing has
been treated in detail in other sections of this
manual. Where it is appropriate, reference will
be made to those sections.

To aid in the establishment of test procedures,
the following recommendations are offered. It is
important to recognize that these
recommendations may not apply to all variations
of materials and that modifications may be
required in performing a practical abrasion test.
They should not be construed as fixed test
specifications.

Analyzing the Test Problem – The value of the

Taber Abraser in research and control programs
depends to a considerable extent on the
operator’s knowledge of the test problem; the
service requirements and the desired wear
characteristics of the material examined.
Analyzing this problem before embarking on a
test series may save time and material. As
nearly as possible, the test should reproduce the
wear experience of the specimen in actual use.

The Test Environment – An environmentally

controlled test room is strongly recommended
where reproducible precision results are
required. Both heat and moisture affect the
abrasion resistance of most materials,
particularly organic materials. Abrasion
research projects are usually carried out in an
atmosphere maintained at 21 - 24°C
temperature and 50 percent relative humidity.
Without exception, samples to be tested should
be conditioned in the test atmosphere for at
least 24 hours – organic materials preferably for
48 hours or more. When research is conducted
to determine wear life under changing
atmospheric conditions, as in automobile and
aircraft materials, the atmosphere of the
laboratory is controlled accordingly.

(70 – 75°F)

 NOTE: If an environmentally controlled test

laboratory is not available, test specimens should be
conditioned and tested with a minimum lapse of time.

U WARNING: When it is necessary to interrupt a

test of organic material for several hours, or
overnight, the sample should be discarded and a
new test begun. In the course of a few hours the
weight of a sample may change by moisture

absorption or for other unexplained reasons.

U WARNING: Although the Abraser is designed to

operate at normal room temperature, it may be
used at temperatures as low as freezing. In
atmospheres approaching 0°C (32°F), allow the
motor to warm up until it reaches normal speed
before lowering the abrading arms. When the
Abraser is not in use, keep it in a room at normal
temperature.

Determining the Test Procedure – Standard

test procedures for a number of materials have
been established and, in the interest of
uniformity and the ready exchange of
information, are very generally accepted. To
ensure that test results will be comparable, the
procedure described should be followed exactly.

In the absence of a standard specification, the
technician must work out his or her own test
procedure. They may begin by referring to the
general recommendations for various materials
shown on pages 32 - 37. Final choice of
abrading wheels, load weights, method of
mounting the sample, kind and duration of test,
and other details may best be decided by
preliminary testing of the specimen material.

Begin by estimating the nature and degree of
wear that the specimen would receive in actual
service. Select an abrasive wheel that will most
nearly reproduce this wear, but will not clog with
the material being tested. Past experience must
guide in choosing the load weight. Under
ordinary conditions a load and wheel
combination should run on a specimen a
minimum of 300 cycles before the end point
occurs, otherwise the test may be too harsh. In
certain instances there may be exceptions to
this rule since there are many varieties of
material that can be tested with the Abraser.

When setting up a test procedure, always keep
in mind to avoid wearing the material too fast as
this will result in ripping and tearing action.

Recording the Test Procedure – It is essential

that careful record of every phase of the test
procedure be kept for purposes of comparison.
This will also enable others to duplicate the test
at a later date. An example of a standard form
for test record is shown on page 48.

Selecting the Method of Evaluating Test
Results – Test results are commonly expressed

as a wear factor or numerical abrasion index of
the test specimen. The most common methods
for calculating this index are by measuring a
visual or physical change. It should be noted
that the wear factor arrived at by any one of the
following four methods is not directly
comparable.

METHOD OF EVALUATION

A single test may correctly indicate the
material’s resistance to abrasion, but it should
not be accepted as a final answer. A minimum
of three to five tests should be made of any
given material and the average result taken to
represent the true value.

A. Visual End Point Method – Certain

materials are best adapted for testing to a
clearly marked change in appearance or
physical breakdown of the specimen. This is
especially true of materials with a plated, glazed,
polished, or printed surface where the end point
is sharply indicated; of materials that withstand
less than 300 abrasion cycles before reaching
the end point of test; and of textile materials.

The visual method is a subjective test that
requires examination of the test specimen, and
should be conducted under controlled lighting.
The test results will be a description of the wear,
and must be as thorough as possible to ensure
all the details of the wear mechanism are
captured. For example if the test specimen is a
coating, one suggestion is to monitor when the
surface coating has worn down enough so that
the substrate material is visible (this is defined
as ‘breakthrough’). For printed specimens,
breakthrough is when a portion of the printing
has fully worn away. Breakthrough testing
should be quantified by recording the number of
cycles it took for breakthrough to occur.

Other examples of Visual End Points:

1. Loss of Luster

2. Changes of Surface Appearance

3. Color Changes

4. Appearance of a Hole

Another option is to compare the abraded
specimens with a measured abraded standard.
A rating scale of 1 – 5 is commonly used to
assist with this type of evaluation, and often
includes a photograph depicting each ranking.

B. Weight Loss Method

method is a quantifiable method in which you
record the weight loss of your test specimen due
to abrasion. To perform this method, you will
need to have access to a precision balance,
preferably one that can measure to the milligram
range since some tests may yield very low
weight loss. Weigh your test specimen before
and after testing to obtain your initial and final
weight values. The difference between these
two values will be your weight loss.

– The weight loss test

29 5135 / 5155 Operating Instructions ver 1.1

Wt

= A – B

Loss

Where,
A = weight of test specimen before abrasion
B = weight of test specimen after abrasion

When performing this method, loose particulate
may adhere to specimens during testing and
handling. It is critical that you clean off the test
specimens as best as possible with a lint-free
cloth or by lightly brushing prior to weighing. If a
sample has been wet tested or if an indicator
has been used, ensure the specimen is
thoroughly dried. If static electricity affects the
specimen, a static eliminator (such as
STATIKIL) may be sprayed on both sides prior
to taking the final measurement.

This method of evaluating test results is
recommended when the results are to be
compared with those of similar materials having
nearly the same specific gravity. The Taber
wear index (rate of wear) is the loss in weight in
milligrams per thousand cycles of abrasion for a
test performed under a specific set of conditions.
The lower the wear index, the better the
abrasion resistance quality of the material.

For example: if a specimen is abraded 5000
cycles and loses 500 milligrams of material, the
wear index should be 100. Likewise, a material
that withstood 500 cycles of abrasion and lost
only 100 milligrams of material would have a
wear index of 200.

EXAMPLE:

500 mg. X 1000 cycles
5000 cycle test (Weight Loss Method)

100 mg. X 1000 cycles
500 cycle test (Weight Loss Method)

= 100 Taber Wear Index

= 200 Taber Wear Index

U WARNING: When using a mounting card, ensure

the cards have been conditioned with the test
specimen. Take the weight measurement A FTER
the specimen has been affixed to the mounting
card.

C. Volume Loss Method – In comparing the

wear resistance of materials having different
specific gravities, a correction for the specific
gravity of each material should be applied to the
weight loss to give a true measure of the
comparative wear resistance. The use of this
correction factor gives a wear index related to
the loss in volume of the material to which it is
applied.

For illustration, consider a hypothetical case
where it is desired to compare the wear
resistance of an aluminum die casting material

with the wear resistance of a similar zinc
material. In this case, three specimens, 100 mm

(4 inch) square by 6.35 mm (0.25 inch) thick, of

each type of material are prepared so that an
average result can be obtained. Each test
specimen is run 5000 cycles, using a CS-17
wheel operating under 1000 gram load. For
purposes of illustration, assume that both the
aluminum and zinc samples showed a weight
loss of 860 milligrams. It would appear that the
materials have equal resistance to abrasion
since their weight loss was equal, however since
aluminum and zinc materials have different
specific gravities a correction factor must be
applied to give a true indication of the wear
resistance. In doing this, the aluminum material
evidences a much greater volume loss, as seen
by comparison of the wear factor:

EXAMPLE:

Aluminum

860 mg. X 1000 cycles

2.7 sp. Gravity x 5000 cycle test (Volume Loss Method)

Zinc

860 mg. X 1000 cycles

7.1 sp. Gravity x 5000 cycle test (Volume Loss Method)

= 63.7 Taber Wear Index

= 24.2 Taber Wear Index

When a clear organic coating is compared with a
heavily pigmented color coat, the latter will, of
course, have a much higher specific gravity as a
result of the added color pigment. It is
recommended that a correction factor be used
based on the amount of solids per gallon of the
liquid material.

D. Depth of Wear Method (Thickness)

–
Certain test requirements may call for measuring
the depth of wear after rotating the specimen a
given number of cycles under a specified
abradant pressure with a particular type of
wheel.

The depth of wear can be measured using an
Optical Micrometer or similar instrument. Place
the measuring device so that it spans both the
abraded and unabraded portion of the
specimen. Calculate the amount of wear by
measuring the difference between the abraded
and unabraded areas in four equal-distant points
around the specimen.

Alternatively, a thickness gage or micrometer
may be used. Mark four points on the back of
an unabraded sample, 90° apart and oriented 38

(1.5 inch) from the center hole [this will be

mm
within the wear path]. Using the measuring
device, determine the thickness and record.
After abrading the sample, repeat the
measurements and record the difference. To
compensate for depth differences around the

30 5135 / 5155 Operating Instructions ver 1.1

specimen wear path, an average should be
computed from the four readings.

EXAMPLE:

0.003” Average Depth of Wear in 5000 Cycles

0.003” x 1000 cycles
5000 cycle test (Depth Method)

= 0.0006 Wear Factor

The specimen material, type of wheels used,
number of cycles, abradant pressure and
average wear depth are then recorded so that
specimen wear characteristics can be
compared.

E. Other Physical Change Methods

–
Performance specifications may be incorporated
when a material is used for a particular
application. For example, a tensile test might be
utilized before and after abrading a textile
webbing material that is used in the manufacture
of seat belts. A Burst test could be incorporated
in evaluating the abrasion resistance of a rubber
seal. Or, an air permeability test might be
included for medical packaging materials that
require the product be kept in a sterilized
environment.

SPECIMEN PREPARATION

Specimen Cleaning

Specimens should be cleaned in such a way
that the surface is free from grit, grease,
fingerprints or other contaminants. Since many
different kinds of materials can be tested, a
specific cleaning treatment cannot be given. If
contact with solvents or cleansers result in
changes to the material properties, surfaces
might be cleaned with isopropyl alcohol or a soft
cloth.

Specimen Conditioning

Prior to testing, it is recommended that
specimens be ‘conditioned’ for at least 24 hours
in the test atmosphere. Organic materials
should be conditioned for 48 hours. The drying
and curing conditions for printing or coating on
plastics versus metals can be different and may
influence the test results. Cure these specimens
under conditions specific to the material. Also,
heat and moisture are known to affect the
physical properties of many materials. It is
recommended that all tests be conducted in the
standard laboratory atmosphere of 23 ±2°C

with 50 ±5% relative humidity.

Rigid Materials

Rigid specimens are often cut from a larger

hole is required.

• It is possible to test specimens without a
center hole by using S-37 or S-37-1
Mounting Sheets and the Drive Pin Type
Holder (E140-19).

• Specimens of uneven thickness should be
shimmed so that the top surface runs true.
A Ring Clamp Specimen Holder (E140-14)
or Threaded Ring Specimen Holder (E140-

21) can be used to test materials that are
slightly warped.

• To subject specimens to a wet abrasion test,
the Rimmed Specimen Holder (E140-75)
can be used. This is useful to determine the
effect of absorbed and / or surface moisture
on abrasion resistance.

Flexible Materials

Most flexible materials can be cut to size using
the Taber Sample Cutter – Model 5000.
Manually operated, this bench top cutter uses an
industrial cutting blade to prepare an exact 107

(4.2 inch) diameter specimen. A punch lever

clutch to punch a 6.35 mm

Textile materials may be prepared using
scissors [approximate size should be 135 mm

(5.25 inch) round or square]. To cut the center

hole, fold the sample twice and cut a small
portion of the resulting corner.

To mount the specimen, place the test specimen
on the holder with the side to be abraded facing
up. Lightly secure the clamp plate and nut in
place to hold the center of the specimen. Adjust
the clamp ring such that it is a snug fit, and
place it half way on the specimen holder. Draw
the fabric taut over the specimen holder by
pulling on corners and edges of fabric. Tighten
the clamp ring further, and push the ring all the
way down over the edge of the holder, thus
putting tension on the fabric as it is secured on

(0.25 inch) center hole.

holder. Finish tightening the clamp plate and
nut, and finally tighten the clamp ring. Avoid
tightening to excess so as not to wrinkle the
specimen. Trim off any excess fabric around the
edges.

Figure 67

When it is desired to use abrasion test samples
for tests of other destructive agents such as
laundering, dry cleaning, and light, it is
recommended that the specimens be cut square
rather than round. The larger area of the square
provides for shrinkage in subsequent tests and
permits handling without touching the wear path.

down into the center recess.

• To prevent stretching or wrinkling of the
specimen during testing, flexible materials
can be mounted to the S-36 or S-36-1
Mounting Card. To prevent the vacuum
from lifting the specimen, it is advised to use
the clamp ring.

• To subject specimens to a wet abrasion test,
the Textile Holder, Tensioning Type for Wet
or Dry Testing (E140-18) can be used. This
holder is designed to give an initial stretch to
woven fabrics so that they may be tested
while moist with minimum tendency to
wrinkle. Alternatively, textile samples may
be adhered to a S-16 specimen plate. The
sample should be cut large and the corners
notched so that it will fold back over the
edges of the S-16 plate without build-up of
material. Take care to iron the folds at the
edges to form a flat, even testing surface.

• A transparent table (E100-10) may be used
for viewing textile specimens against a
strong light to determine the worn condition
of the threads without removing the fabric
from the holder. The E100-10 can also be
used with a small, high intensity light bulb
located beneath the specimen holder which
activates a photocell and electronic relay to
turn off the Abraser when the established
wear point is reached.

Coatings

A coating that is representative of the coating
applied to actual product is required for
accurate, dependable results. Test panels
should be sprayed, drawn down or control­dipped to achieve a uniform coating. Brush
application is not recommended where precision
results are desired. Paints, lacquers, and similar
coatings can be applied directly to specimen
plates available from Taber Industries:

(0.25 inch) center hole.

 NOTE: Before applying the coating, S-16 plates must

be thoroughly cleansed of dirt, grease or other
contaminants. Use of a solvent degreaser or other
solvent cleaner capable of dissolving and removing oil,
grease and solid particles is suggested.

Panels dipped or sprayed on both sides should
be marked with an “A” or “B” to identify the front
and back surfaces and their respective tests. An
extra heavy application may not dry with the
same physical properties as a light coating.

When preparing your own test panels, ensure
the sides are flat and parallel. A simple means
to check for flatness is to place a straight edge
across the test panel surface, and verify there is
no gap. Use a file to remove any burrs from the
center hole and edges.

(measured off the specimen surface). Other
factors to consider include specimen
conditioning, environmental conditions, vacuum
suction level, specimen cleaning, and test
cycles. Specimens must have a flat, even
surface and run true.

In the following procedures, it is assumed that
tests are conducted in an atmosphere controlled
to 50 percent humidity and 21 - 24°C

(70 – 75°F)

temperature. Also, samples are conditioned in
the test atmosphere for at least 24 hours before
testing.

Evaluation: Visual end point, at the first sign that
the wheels have worn through the coating to the
substrate; weight loss method, without
permitting the wheels to wear through to
substrate; or change in coating thickness.

Remark 1: Accurate, dependable evaluation of the abrasion
resistance of organic coatings requires application of a
uniform film of normal thickness (such as that applied in
actual production practice).

Remark 2: Prior to applying a coating, the substrate should
be thoroughly cleansed of dirt and grease.

Remark 3: The effect of age on organic materials and
coatings bears close investigation. Many coatings show low
abrasion resistance the first few days but progressively
improve during the following 30 days due to curing.

conditions.

Remark: The color difference between the nickel and
chrome is so slight that it is necessary to prepare and use an
indicator solution that will blacken the nickel but not attack
the chrome. At intervals during the test, moisten the wear
path with the solution applied with a cotton swab on the end
of a stick. Discoloration indicates that the abrading wheels
have penetrated the chrome deposit. Clean the solution from
the specimen before resuming the test.

the plates is likely to cause some shattering of the enamel,
this is permissible if it does not extend into the path of the

test may be continued to a more advanced end
point than the first sizeable scratch.

Remark 1: The hardness and density of porcelain enamel
makes them highly resistant to abrasion and scratching.
Because of the similarity of porcelain glaze with glass, the
abrading action of the Calibrase wheels is barely noticeable
in the early stages of the test although material is being
slowly removed. After a time, however, the wheels begin to
abrade through the surface glaze and penetrate the coarse
substrate.

Remark 1: In making the test, it is necessary to allow for the
fact that the wheels will become coated with wax transferred
from the specimen. Depending on the number of test cycles,
wheels may require refacing during testing.

Remark 2: A coating of wax applied to a surface has
practically no abrasion resistance of itself but does act as a
lubricant which reduces the tendency of two surfaces
rubbing together to abrade. This lubricating effect prolongs
the life of the finish to varying degrees, and the action of the
wax is similar to that of grease in lubricating mechanical
devices.

Specimen: To prepare the specimen, an S-36-1
mounting card is placed on the specimen holder.
An abrading wheel cap nut is placed temporarily

circumference of the guide to the edge of the
holder. The cap nut guide is then removed and
the coiled wire specimen, mounted on its holder,
is placed against a flat surface and weighted
with 5 pounds for 1 hour. The specimen holder
clamp plate and clamp ring are attached to the

dimensions of the fibers; the structure of the
yarns; the construction of the fabrics; and the
type, kind, and amount of finishing material
added to the fibers, yarns or fabrics. For rigid
materials, material surface roughness should be
considered.

The effect of age may impact the abrasion
resistance of organic materials and coatings.
Many coatings show low abrasion the first few
days but progressively improve during the
following 30 days as the coating cures.

The type of abradant used also plays an
important role. All abrasion tests are subject to
variation due to changes in the abradant during
specific tests. To minimize this variation, the
abradant must be cleaned at frequent intervals
and checked periodically.

Figure 81

Remark: Use of an electrical current to detect the end point
automatically, is suggested. One end of the specimen wire
may be grounded and a soft wire tinsel brush, in contact with
the wear path, conducted to a suitable electronic switch to
stop the abraser at a predetermined end point corresponding
to the breakdown of the insulation.

such as decking, can be determined by soaking the wood in
water for a specified length of time and testing in that
condition using the rimmed specimen holder (E140-75).

INFLUENCES ON RESULTS

The measurement of abrasion resistance is a
complex phenomenon and may be influenced by
a number of factors. If there are significant
differences between reported test results for two
laboratories (or more), it is often attributed to
procedural errors, an instrument that is out of
calibration or one of the factors mentioned
below.

The resistance to abrasion is greatly affected by
the characteristics of the material itself. For
example, textile materials are affected by the
inherent mechanical properties of the fibers; the

Other factors to consider include the conditions
of the tests (i.e. temperature and humidity,
conditioning of specimens, etc.), and test
methodology (i.e. vacuum nozzle height,
pressure between the specimen and abradant,
etc.). For comparable and reproducible tests, it
is recommended that all testing be performed
under conditions covered by an established test
procedure.

The measurement of the relative amount of
abrasion may also be affected by the method of
evaluation. This is especially true with visual
assessments, as the results may be influenced
by the judgment of the operator.

If a thorough investigation does not uncover the
cause for the difference, comparative tests
should be performed to determine if there is a
statistical bias between the laboratories. The
test samples used must be as homogeneous as
possible, drawn from the material from which the
disparate test results were obtained, and
randomly assigned in equal numbers to each
laboratory for testing. The test results from the
laboratories should be compared using a
statistical test for unpaired data, at a probability
level chosen prior to the testing series. If bias is
found, either its cause must be found and
corrected, or future test results must be adjusted
in consideration of the known bias.

MAINTENANCE

The Rotary Platform Abrasion Tester is a
precision instrument that, if used and maintained
properly, should give you many years of trouble­free service. This section will provide a general
guideline in caring for your instrument.

40 5135 / 5155 Operating Instructions ver 1.1

General Care

As with any precision test instrument, basic
common sense care will ensure a long life from
your Rotary Platform Abrasion Tester. Brush or
vacuum all particulate material and debris off the
instrument and surrounding work area. The
motor drive shaft cavity is prone to collect
debris. Periodically, remove the specimen
holder and vacuum this area using the suction
brush attached to the vacuum hose or Taber
Clean Up Hose.

be used or to clean the motor cavity.

Each specimen table is designed with a drive pin
and ball plunger to provide a positive retaining
force that locks the specimen holder in place.
To remove the holder, place your fingers under
the edge of the holder and lift straight upward.
In the event that the holder cannot be removed,
DO NOT USE a tool to pry the table up. Contact
Taber Industries for further instructions.

Figure 83

Figure 82

Keep the vertical drive shaft of the Abraser and
the shaft holes of the specimen holders wiped
clean with a soft cloth. Drive shaft and holder
bores are machined to close tolerances. Never
force on a holder when dirt is present. This may
damage the holder bore and affect its accuracy,
or make it impossible to remove the holder
without damaging the motor.

 DO NOT allow any foreign particulate to get

into any of the bearing assemblies.

 DO NOT spill any liquids onto or into the

instrument or onto any of the bearing
assemblies. Wipe off all spills immediately.

 DO NOT operate the Rotary Platform

Abrasion Tester at freezing, sub-zero or
elevated, high temperatures. The
instrument is designed to operate in a
temperature range at or around room
temperature and in nominal room humidity.

Lubrication

The bearing assemblies are factory lubricated
and do not require regular lubrication.

Installing / Removing the Specimen
Holder

With frequent specimen holder removal, the ball
plunger may need to be adjusted. Using a
screwdriver, tighten the ball plunger
approximately 1/16 turn. A silicone type spray
may be used to lubricate.

To install the specimen holder, align the bottom
opening with the vertical drive shaft of the
Abraser motor making sure that the ball plunger
and drive pin are aligned. Using a downward
force, press lightly on the specimen table until it
is fully seated.

Cleaning Vacuum Pick-Up Nozzle

Abraded material and debris may collect in the
vacuum pick-up nozzle orifices. Keep the
orifices clean of particulate by using a small
brush.

Replacing Quick Release Wheel Collet

The expandable collet for the Quick Release
Wheel Hub is manufactured out of a wear
resistant plastic, however it should be replaced
when the retaining lip shows signs of wear. An
indication of this wear is a rounding of the lip or
wheels are no longer held securely in place. To
facilitate this repair, a replacement collet kit is
available from Taber Industries.

The specimen holder can be removed from the
instrument. This will allow for optional holders to

OPTIONAL ACCESSORY INSTRUMENTS

Sample Cutter 5000

The Model 5000 Sample Cutter is available to prepare a wide range of

flexible materials for testing on the Taber Rotary Platform Abraser.
Examples include: paper, cardboard, rubber, leather, vinyl, carpet, textiles,
metal foils, and flexible plastics.

This bench top instrument is designed to cut an exact 108 mm
diameter specimen and punch a 6.35 mm
tail’ rear support prevents tipping during operation, thereby eliminating the
need to secure the instrument to a work surface. A shielded punch shaft
and knife retraction system protects the operator from the cutting tools.
The punch lever is ergonomically designed to evenly transfer force through
the spring-loaded punch.

(4.2 inch)

Wheel Refacer 250

The Model 250 Wheel Refacer has been specially designed to

precision dress the working surfaces of Genuine Taber Calibrade
abrading wheels for the Taber Abraser. This compact instrument can
also be used to true out of round wheels and to correct ‘crowning’
conditions on both Calibrase and Calibrade wheels.

A refacing diamond tool is mounted in an adjustable holder, which is
supported on a shielded traverse slide. Abrading wheels are mounted
on a flanged extension of the motor shaft and are enclosed by a
hinged cover for safety during the refacing operation. By moving the
diamond point tool across the wheel faces, the wheel surfaces can be
refreshed! During operation, the vacuum unit hose is disconnected
from the Abraser and inserted in the Wheel Refacer to draw off the
abrasive cuttings. Note: To ensure identical diameters, wheels are
always refaced in pairs.

Quiet Cabinet

The Quiet Cabinet can significantly reduce the sound levels associated

with running a Taber test. Additionally, it provides a convenient, dust-free
workspace for the instrument. The typical sound level of the Taber
Abraser and its vacuum system can reach 78dB. Utilizing sound
deadening materials, the Quiet Cabinet reduces this noise level up to
20% resulting in a level that is comparable to a standard office
environment.

The upper cabinet features a hinged Plexiglas™ viewing window to
monitor testing while a detachable front permits easy transfer of the
Abraser into or out of the cabinet. The lower cabinet holds the vacuum
unit and includes a built-in exhaust system (either 120V, 60Hz or 230V,
50Hz) to provide proper air circulation. Constructed of solid wood, the
cabinet includes a high-pressure laminate outer shell for added durability.
The Quiet Cabinet is available as a complete unit, or the top and bottom
may be purchased separately.

Grit Feeder Attachment 155 / 255

The Model 155 or 255 Grit Feeder is used in conjunction with the Taber

Abraser to evaluate three-body abrasion caused by the destructive action
of fine, hard particles. Positioned over the Taber Abraser, the Grit Feeder
is a freestanding instrument that deposits abrasive grit particles uniformly
and continuously onto the specimen surface. As the specimen holder
rotates, the loose grit passes under a pair of leather-clad wheels. The
resulting rolling action of the particles serves as the abradant and
contributes to the physical breakdown of the material. The vacuum hose
from the Taber Abraser is inserted into the base of the Grit Feeder allowing
a pickup tube to be positioned such that grit particles and debris are
removed. The operation of the grit feeder is controlled through the Taber
Abraser, ensuring that the turntable, grit distribution and vacuum suction
are actuated at the same time.

Two versions of the Grit Feeder are available, Model 155 and 255. Model
155 offers a hopper capacity of 1,300 grams and utilizes and alignment guide screw to set the position of
the instrument. Grit distribution and vacuum removal nozzle heights are adjusted using a thumbscrew.
Model 255 offers an increased hopper capacity of 4,500 grams. A telescoping feature allows precise
height adjustments and permits testing of specimens up to 50 mm

(2 inch). An alignment block is

incorporated into the base to assist with proper set-up. In addition, the Model 255 may be mounted to
either the right or left hand side of the Abraser, enabling two instruments to be used with Taber’s Dual
Rotary Abraser.

Multi-Media Abraser 5500

The Model 5500 Multi-Media Attachment is an accessory attachment for the

Rotary Platform Abraser used to evaluate particle abrasivity. Applications
include fluids, powders and semi-solids such as paints, pigments, adhesives,
sealants, epoxies, detergents and industrial additives. This option enables
the user to recreate actual wear conditions for contact surfaces in application
equipment, and is useful in predicting maintenance schedules.

The test medium to be evaluated is placed in a testing dish. As the dish is
rotated, a holder with three precision brass pins affixed to it rotates in the
opposite direction on a stainless steel wear disc. As the test medium flows
against the brass pins, abrasion occurs resulting in a change in weight. With
interchangeable gearing, the speed of rotation for the pin holder can be
changed which permits the testing of different material viscosity.

Scuffing Head Attachment

The Scuffing Head Attachment is used to evaluate damage

caused by the scraping action of a special scuffing head. Used
on materials such as vinyl, leather, textiles, non-woven
materials, plastics and painted products; two different weights
and three scuffing head configurations are available. Scuffing
head type “A” is similar to the flat blade of a screwdriver [blade
is approximately 8 mm
edge [blade is approximately 4 mm
“C” has a radius edge [blade is approximately 8 mm
wide].

(0.31 inch) wide]. Type “B” has a knife

(0.157 inch) wide], and type

(0.31 inch)

Used in place of the abrasive wheels, the Scuffing Head Attachment is mounted on the inside riser mount
for the left abraser arm. The abraser is operated in the normal fashion, however the vacuum system is
not utilized. With a hinged design, the scuffing tool may be raised when not in use.

Haze Kit

The Haze Kit is intended for those customers who perform abrasion testing on plastics or glass. This kit

includes a modified vacuum pick-up nozzle with 11mm

(0.3125 inch) openings. Also supplied are a 0.8 mm (0.0132 inch) gage pin for setting the gap between

8mm

(0.4375 inch) orifice openings versus the nominal

the specimen and vacuum nozzle and an antistatic brush for cleaning the specimen.

Arm Height Extension Kit

The Arm Height Extension Kit was engineered to accommodate specimens that exceed the

recommended thickness [up to 40mm (1.5 inch)]. This kit raises the position of the abrader arms and
allows for the correct alignment and positioning of the abrasive wheels. An extension post is threaded to
the turntable and by using the appropriate combination of turntable shims the proper arm position relative
to the specimen. Kits are available for Single and Dual abrasers and include the arm height extenders,
turntable adaptor and a set of 6 shims.

It is necessary to return your instrument to Taber Industries for

Calibration Verification Kit

Instrument verification can be performed using the Calibration Verification Kit. This cost effective method
enables the operator to verify if an instrument is in calibration or if it is in need of repair. Procedures
described in the kit allow the verification of proper abraser arm alignment (longitudinal and transverse
alignment), wheel tracking and wear pattern, irregular bearing integrity and vacuum suction force. Other
inspections include vacuum pick-up nozzle wear, table flatness, turntable speed and accessory weights.
This kit is NOT intended as a substitution for regular instrument calibration.
