significance And Use:
Overtesting should be done when (a) testing by variables is impractical because of time and cost considerations or because the probability distribution of stress to failure cannot be estimated... View More
scope:
1.1 This guide covers the use of overtesting in order to reduce the required number of parts that must be tested to meet a given quality acceptance standard. Overtesting is testing a sample number of parts at a stress higher than their specification stress in order to reduce the amount of necessary data taking. This guide discusses when and how overtesting may be applied to forming probabilistic estimates for the survival of electronic piece parts subjected to radiation stress. Some knowledge of the probability distribution governing the stress-to-failure of the parts is necessary though exact knowledge may be replaced by over-conservative estimates of this distribution.
