Software Verification and Validation
MTS software is developed using established quality practices in accordance with the requirements detailed
in the ISO 9001 standards. Because MTS-authored software is delivered in binary format, it is not user
accessible. This software will not change over time. Many releases are written to be backwards compatible,
creating another form of verification. The status and validity of MTS’s operating software is also checked
during system verification and routine calibration of MTS hardware. These controlled calibration processes
compare the final test results after statistical analysis against the predicted response of the calibration
standards. With these established methods, MTS assures its customers that MTS products meet MTS’s
exacting quality standards when initially installed and will continue to perform as intended over time.

2.0 Preface
2.1.0 Before You Begin
Safety first!
Before you use y our MTS product or system, read and understand the safety information provided with your
system. Improper installation, operation, or maintenance can result in hazardous conditions that can cause
severe personal injury or death, or 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 manuals in paper or electronic form.
You may also receiv e an MTS System Documentation CD. It contains an electronic copy of the manuals that
pertain to your test system.
Controller and application software manuals are typically included on the software CD distribution disc(s).
2.2.0 Documentation Conventions
The following paragraphs describe some of the conventions that are used in your MTS manuals.
Hazard conventions
Hazard notices may be embedded in this manual.These notices contain safety information that is specific
to the activity to be performed. Hazard notices immediately precede the step or procedure that may lead to
an associated hazard. Read all hazard notices carefully and f ollow all directions and recommendations.Three
different levels of hazard notices may appear in your manuals. Following are examples of all three levels.
(for general safety information, see the safety information provided with your system.)
DANGER:
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:
Warning notices indicate the presence of a hazard with a medium lev el of risk which,
if ignored, can result in death, severe personal injury, or substantial property damage.
MTS TestSuite 13
CAUTION:
Caution notices indicate the presence of a hazard with a low level of risk which, if
ignored, could cause moderate or minor personal injury or equipment damage, or
could endanger test integrity.
Other special text conventions
Important:
Important notices provide information about your system that is essential to its proper
function.While not safety-related, if the important information is ignored, test results may
not be reliable, or your system may not operate properly.
Note:
Notes provide additional information about operating your system or highlight easily
overlooked information.
Recommended:
Recommended notes provide a suggested way to accomplish a task based on what MTS
has found to be most effective.
Tip:
Tips provide helpful information or a hint about how to most efficiently accomplish a task.
Access:
Access provides the route you should follow to a referenced item in the software.
Example:
Examples show specific scenarios relating to your product and appear with a shaded
background.
Special terms
The first occurrence of special terms is shown in italics.
Illustrations
Illustrations appear in this manual to clarify text.They are examples only and do not necessarily represent
your actual system configuration, test application, or software.

3.0 Overview
3.1.0 Template Overview
3.1.1.0 Templates
Templates eliminate the need to re-create existing information and provide an easy wa y to run standard tests.
Test templates can come from one of several sources:
• An existing test - you open a copy of an existing test and assign it a default name (the original test is not
changed).The new test does not contain test runs or analysis runs from the source test.
• A test that is converted to a template - you can convert a test to a test template (File > Save As > Template).
With the exception of test and analysis runs, specimen definitions, and completed reports, the template
contains all other test information.
• A template supplied by MTS - MTS offers a variety of templates designed to comply with test method
standards (such as ASTM). MTS templates provide all the components you need to run a test, analyze
the test data, and create reports of the results.
Test template content
A template can include all or part of the basic test definition information for one test:
• Procedure
• Monitor displays
• Variables
• Analysis definitions
• Resources
Note:
Although a template can include test resources, if the template is designed for a particular controller
configuration, the resources may not map to (match) the test station resources in your system.
Test definitions
You can add a test definition to a test from a template.The source of the template can be any existing test
or template that has tests.With the exception of test and analysis runs, specimen definitions, and completed
reports, the new test contains all other test information.
Template locations
Projects and project templates exist on disk as folders with the .Project folder name extension.They are
typically located at C:\MTS TestSuite\Projects and C:\MTS TestSuite\Templates, respectiv ely . Report templates
are located in the C:\MTS TestSuite\Report Templates folder.

Note:Do not rename, move, or change the contents of the Projects or Templates folders outside of
the MTS TestSuite applications.To rename an open project, use the Project Summary window in any
application.

5.1.0 Set Up the Test
5.1.1.0 ASTM Low-Cycle Fatigue (LCF) Strain Template
The Low-Cycle Strain template applies a small number of high-amplitude cyclic forces to the specimen to
determine the maximum load or fatigue life of a material. A variation of the template performs the test at an
elevated temperature. Both templates are designed to be in compliance with ASTM standard E606-04 and
D3479-07.
After a test run and a specimen geometry are added, a window provides access to all test parameters and
test operation steps.The buttons enable you to perform the steps to run a low-cycle fatigue test.The general
order of the buttons is left to right, from the top row to the bottom row.
As the test runs, you can stop the test to change test parameters. After the test is complete, the data can be
analyzed.
The main features of the low-cycle fatigue template include:
• Buttons enable you to:
• Set up all test parameters
• Verify and reattach the extensometer
• Measure the modulus
• Run the test
• Create a report
