3 Terms and definitions

GB/T 2900.13-2008 defined and the following terms and definitions apply to this document. 3.1 Acceleration factor The ratio of failure distribution characteristics (or reliability level) of a product under expected stress conditions to high stress conditions. Note 1. For accelerating tests, the acceleration factor is greater than one. Note 2. When the product is assumed to have a Poisson distribution of constant failure rate, the acceleration factor refers to the time the product is under stress and the time under high stress ratio. 3.2 High acceleration limit test highlyacceleratedlimittest; HALT Under specified environmental stress, the test or test sequence used to identify the most likely mode of failure of the product. Note 1. HALT is sometimes mistakenly referred to as a high accelerated life test. Note 2. As an accelerated test of non-index evaluation, it can not obtain the information of product life but can get the information of product design stress limit. 3.3 Class A accelerated test typeAacceleratedtest Qualitative acceleration test, mainly for the discovery of failure mode and (or) failure phenomenon. The purpose of this type of test is not to determine the value of quantitative indicators of product reliability, but rather to stimulate the functional performance of the product during the experiment. Note In the product development process, the use of Class A accelerated test without verifying the reliability of indicators and access to the reliability of growth in the case, by reducing the failure mode Increase the number of products and enhance product robustness to improve its reliability. 3.4 Type B accelerated test typeBacceleratedtest Quantitative acceleration test, mainly for the normal use of the product failure distribution. It is the level of reliability that is used to determine the expected life of a product using stress-cumulative damage methods.
