5.3.1 Suitability for Environment
Ensure the sensors and instrumentation to be used for recording environmental conditions and responses are suitable for the intended environments. For example, accelerometers used in a combined high temperature/vibration test could give erroneous readings if not designed for high temperature use.
5.3.2 Calibration
Prior to and following each test, verify the accuracy of instruments and test equipment used to control or monitor the test parameters. Calibration intervals must meet the guidelines of ANS/ISO/IEC 17025:2005, ANSI/NCSL Z540.3-2007 or ISO 10012 to the satisfaction of the procuring activity. All instruments and test equipment used in conducting the tests in this document should:
- a. Be calibrated to laboratory standards, traceable to the National Standards via primary standards.
- b. Have an accuracy at least equal to 1/3 the tolerance of the variable to be measured. In the event of conflict between this accuracy and guidelines for accuracy in any one of the test methods of this standard, the latter governs.
