GB/T 3187-1994 Terminology of Reliability and Maintainability (eqv IEC 191-1:1990) GB/T 4086.2 Statistical Distribution Value Table X Distribution Terms and Definitions The terms and definitions established in GB/T 3187-1994 are applicable to the general requirements of this standard for reliability, and the limit values of m are used as indicators of reliability. The limit values of m for different products should be specified in the product specifications. The types of tests are divided into identification tests, acceptance tests, and on-site tests based on the different stages of product development and different testing purposes. The purpose of reliability appraisal test is to verify whether the production factory has the ability to produce products that meet reliability requirements. The results of the appraisal test are used to determine whether the reliability of the product meets the requirements under the following conditions: a) design finalization; b) Production finalization; c) Identification after significant changes in design and process
