Preface
Before You Begin
Safety first! Before you attempt to use your MTS product or system, read and understand the
Safety manual and any other safety information provided with your system.
Improper installation, operation, or maintenance of MTS equipment in your test
facility can result in hazardous conditions that can cause severe personal injury or
death and damage to your equipment and specimen. Again, read and understand
the safety information provided with your system before you continue. It is very
important that you remain aware of hazards that apply to your system.
Other MTS manuals In addition to this manual, you may receive additional MTS manuals in paper or
electronic form.
If you have purchased a test system, it may include an MTS System
Documentation CD. This CD contains an electronic copy of the MTS manuals
that pertain to your test system, including hydraulic and mechanical component
manuals, assembly drawings and parts lists, and operation and preventive
maintenance manuals. Controller and application software manuals are typically
included on the software CD distribution disc(s).

Documentation Conventions
The following paragraphs describe some of the conventions that are used in your
MTS manuals.
Hazard conventions As necessary, hazard notices may be embedded in this manual. These notices
contain safety information that is specific to the task to be performed. Hazard
notices immediately precede the step or procedure that may lead to an associated
hazard. Read all hazard notices carefully and follow the directions that are given.
Three different levels of hazard notices may appear in your manuals. Following
are examples of all three levels.
Note For general safety information, see the safety information provided with
your system.
Danger notices indicate the presence of a hazard with a high level of risk which,
if ignored, will result in death, severe personal injury, or substantial property
damage.
Warning notices indicate the presence of a hazard with a medium level of risk
which, if ignored, can result in death, severe personal injury, or substantial
property damage.
Caution notices indicate the presence of a hazard with a low level of risk which,
if ignored, could cause moderate or minor personal injury, equipment damage, or
endanger test integrity.
Notes Notes provide additional information about operating your system or highlight
easily overlooked items. For example:
Note Resources that are put back on the hardware lists show up at the end of
the list.

MTS Series 642 Bend Fixtures test the flexural bending properties of specimens.
The grips are suited for fracture toughness tests (ASTM E-399), plastics tests
(ASTM D-790, flex test), and composites tests (ASTM D-2344, short beam
shear).
Note This manual covers the Model 642.001, 642.01A, 642.10B, and 642.25
Bend Fixtures, all of which have the same basic components. The
illustrations on most of these pages show only the Model 642.10B, but
the information provided applies to all four models. Where differences
occur among the different models, these will be pointed out. Modelspecific illustrations are also included where appropriate.

What you need to
know
MTS Systems Corporation assumes that you know how to use your controller.
See the appropriate manual for information about performing any controllerrelated step in this manual’s procedures. You are expected to know how to
perform the following procedure
• Turn hydraulic pressure on and off (for servohydraulic systems) or turn
electrical power on and off (for electromechanical systems).
• Select a control mode.
• Manually adjust the actuator (servohydraulic) or crosshead
(electromechanical) position.
• Monitor a sensor signal.
• Zero a sensor output.
• Install a specimen.
• Define a simple test.
• Run a test.
Series 642 Bend Fixture Functional Description
The bend fixtures have an upper and lower bedplate that attach to your load unit’s
force transducer and actuator with cap screws. The Model 642.001, 642.01 and
642.10 bend fixtures attach directly to the actuator and force transducer, while
the Model 642.25 Bend Fixture uses an adapter plate to attach to the actuator and
force transducer.
Adjustable roller block assemblies slide back and forth in the bedplates, giving
you different loading spans. The bedplates have scales, in metric and US units,
for accurately adjusting the loading spans.

loading. Four-point loading uses two roller block assemblies in the upper
bedplate and two in the lower bedplate. Three-point loading uses two roller block
assemblies in the lower bedplate and a three-point option kit attached to the load
cell.
Different diameter rollers can be used with the same roller block assemblies.
Standard roller diameters are 0.125, 0.250, 0.375, 0.500, 0.750, 1.0, 1.25, 1.5,
1.75, and 2.0 inch, as well as 5, 8, 10, 12, 20, 30, 40, and 50 millimeter (see the
tables on pages 14–18 for individual model standard diameters). MTS can also
build rollers with custom sizes. See your sales representative if you require
rollers of non-standard size.
