Scope

Scope: This standard specifies the method for conducting product reliability verification based on accelerated testing, and develops and extends the reliability verification method based on simulation experiments. It can provide guidance and reference for implementing accelerated reliability verification tests of products and determining whether the reliability level of products meets the index requirements. This standard applies to mechanical and electromechanical products whose product lifespan follows an exponential distribution, Weibull distribution, or lognormal distribution, and whose acceleration models and degradation models can be converted into linear models. It can also be used as a reference method for other lifespan distributions and acceleration/degradation models. This standard is suitable for products with clear failure modes and failure distributions, and for products where accelerated tests can be implemented as a whole. This standard provides timing truncation test schemes under accelerated testing conditions. For fixed-number truncation test schemes and sequential test schemes, it can be used as a reference method.
