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 the 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 exacting
quality standards when initially installed and will continue to perform as intended over time.
