Software validation and

Publication information
MTS software is developed using established quality practices in accordance
with the requirements detailed in the ISO 9001 standards. Because MTSauthored 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’ 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’ exacting
quality standards when initially installed and will continue to perform as intended
over time.

Introduction
Contents Functional Description 6
The AHX800 High Elongation Extensometer is designed for testing high
elongation applications of elastomer materials such as latex, silicone, rubber,
polyurethane, and other similar materials. It is ideally suited for testing dog-bone
elastomer specimens per ASTM D412 and ISO 37 specifications.

Functional Description
The AHX800 High Elongation Extensometer is designed to operate at
temperatures from 5 to 40°C. The key part of the extensometer is an optical
encoder. The movement of the extensometer arms makes the optical encoder
rotate. The encoder send pulses to a circuit where the pulses are converted for use
by the controller.

Introduction
Frame Assembly (all other component s)
The two arms of the extensometer are attached to the specimen. A cable/pulley
mechanism allows the arms to track the elongation of the specimen. The cable
movement is detected by an encoder. The encoder sends pulses to a circuit board
that converts the pulses to determine the exact displacement of the extensometer
arms.
The high elongation extensometer can rotate 90° to minimize the required
working space.
