gjb450-88装备研制与生产的可靠性通用大纲新版（New general outline of reliability for equipment development and production of gjb450-88） New general outline of reliability for equipment development and production of GJB450-88 The main content of the standard This standard is compared with the original standard, the content is the first GJB45088 classification of reliability test is introduced, which is based on the test site, the equipment reliability test is divided into laboratory test or field test. The laboratory reliability test is a reliability test under the controlled and controlled working environment. The working environment can be simulated or not simulated. Field reliability test is a reliability test or measurement test carried out on the spot. The working environment, maintenance and measurement conditions shall be recorded. According to the requirements of the development, production and use of communication equipment at various stages, from the nature of reliability test, there are mainly reliability engineering test and reliability statistical test. Reliability engineering tests consist of environmental stress screening (ESS) and reliability growth tests that expose failures and eliminate them, usually at the development stage, so this standard introduces only relevant concepts. Reliability statistical tests include reliability test and reliability test, which are to verify whether the equipment meets the requirements and to determine the reliability value of the equipment. It is usually carried out in the development and production stages. This standard applies to reliability statistical tests. Not suitable for environmental stress screening and reliability growth test. This standard gives a systematic explanation of reliability statistical tests. The test procedure, test scheme and selection, performance test and maintenance in the process of failure, and the reliability index calculation, and the key that the number and calculate the total test time, the confidence
