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).

Conventions

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.

About the Series 658 Environmental Chamber

The MTS Series 658 Environmental Chamber was engineered for compatibility
with MTS Model 810, and Model 858 Bionix, and Mini Bionix load frames. It
has an acrylic chamber and its transparent walls allow easy viewing when non­opaque fluids are employed in the test. The walls are compatible with the
relatively moderate temperatures typically employed in simulating the
biomaterials service environment.

The design accommodates a variety of fixture and specimen heights and provides
easy access for specimen and fixture attachment. The separate chamber sections
are sealed with O-rings, and easily moved when fluid is pumped out of the
chamber.

Series 658 Environmental Chamber Introduction

13

Mounting brackets and clamps on the base of the Model 658.25 chamber provide
for easy installation and height adjustment. The chamber attaches directly to the
load frame columns. The base of the chamber is equipped with a lip and serves as
a catch basin for minor test medium spills.

Mounting of the model 658.07 uses an attachment kit that installs directly onto
the pull rod.

Constant temperature control is regulated by the NESLAB EX-10 Digital One
Heating Circulator Bath circulating fluid through the heating coil within the
chamber (658.25) or through the chamber itself (658.07). Low level fluid sensors
will shut the system down if the fluid drops unexpectedly to preset minimum
levels.

The standard Model 658 system includes a chamber, closed-loop heating system,
and low level protection.

Spray nozzles provide a continuous fine mist equivalent to a 100% humidity
condition with 0.9% saline solution. Spray nozzles can be positioned in any
direction. The spray system takes fluid from the NESLAB EX-10 Digital One
Heating Circulator Bath reservoir to inject into the nozzle(s) within the chamber.
This provides a saturated spray environment.

Optional pull-rods are used inside the environmental chamber. A flexible bellows
tightly seals these rods. The pull-rods are easily attached to the load cell
(mounted on the base plate of the Bionix load frame) and to the crosshead.

The chamber will work with both axial and axial-torsion grips designed by MTS
to withstand the corrosive environment of the chamber. For axial-only testing,
simple L-clamp grips of titanium or stainless steel are available. Also bollard
grips for sutures, fine wires, filaments, and other threads and thread-like
materials are available.

For both axial and axial-torsional testing, MTS has developed immersible axial­torsion grips that can be used with both round and flat specimens. These grips are
designed for loads up to +/- 10 kN (2,200 lb) axial with +/- 100 N·m (1000 in. lb)
torsional.

This section describes how to install the Model 658.25 Environmental Chamber
in a typical load unit; the Series 359 Load Unit is used in the illustrations but the
procedure can also apply to the Series 318 Load Unit. This section also describes
connecting the hoses to the fittings on the bottom of the chamber base and the
fittings on the heating circulator bath.

Installing the 658.25 Chamber in the Load Unit

To install the 658.25 Environmental Chamber into the load unit:

1. Install the column clamps. Position them just above the expected final
position and snug in place; do not tighten.

2. Secure the chamber mounting plates to the chamber base.

3. Position the membrane on the chamber base. Line up the mounting holes.

4. Place the membrane retainer ring on the membrane and secure with nylon

5. Place the chamber mounting plates with the chamber base attached on the
column clamps.

7. Make sure the column clamps and chamber mounting plates are level.

8. Tighten the column clamps onto the columns. Secure the chamber mounting
plates to the column clamps.

9. Push a couple sockethead cap screws up through the mounting holes in the
lower pullrod. Line up the screws with the threaded holes in the pullrod
attachment and place the pullrod attachment on top of the lower pullrod.
Install the eight sockethead cap screws. Snug in place; do not tighten.

10. Ensure that pieces are positioned properly. Make sure the chamber base is
level, the membrane is parallel with the lower pullrod, and the pullrod
attachment is positioned properly in the pilot and resting evenly on the
membrane.

11. Tighten the eight sockethead cap screws. Tighten screws evenly in a
crisscross pattern.

Installation

12. Install the sprayers onto the appropriate fittings on the chamber base. Push
the jointed tubing onto the fittings until secure. There are no fasteners.

13. Install the heater coil. Place the heater coil over the spray nozzles and
tighten the compression fittings.

14. Install the lower chamber extension onto the chamber base.

15. Install the upper chamber extension onto the lower chamber extension.

16. Install the chamber cover halves onto the upper chamber extension.
