National Aeronautics and Space Administration (NASA). This Technical Standard approved by NASA July 10, 1996. 14 p. This standard includes selected environmental exposure tests. Those tests included are generally regarded as the most critical and the ones having the highest cost and schedule impact. This standard also includes functional demonstration tests necessary to verify the capability of the hardware to perform its intended function (with and without environmental exposure as appropriate). This standard specifies test levels, factors, margins, durations, and other parameters where appropriate. In some cases, these specifics are expressed statistically or are referenced to other NASA standards
