Scope

Main technical content: This document specifies the method of conducting accelerated life tests and accelerated degradation tests using step-down stress, which can provide guidance and reference for implementing product accelerated tests, evaluating product reliability, and predicting product lifespan. This document is applicable to cases where product lifespan follows a Weibull distribution, and it can also be used as a method reference for other lifespan distributions. This document assumes that the product meets the single-failure assumption, that is, there is a dominant single failure mode or a single degradation mode. This standard does not address the application scenarios of multiple failure modes or multiple degradation modes.
