Introduction of QJ A 1408-1998

Reliability assurance requirements for aerospace products 1 Scope 1.1 Subject content This standard specifies the general requirements, work items and implementation requirements for reliability assurance of aerospace products. 1.2 Application scope This standard is applicable to various stages of spacecrafts and launch vehicles (including ground equipment) such as feasibility demonstration, scheme, engineering development (prototype, test prototype/flight model) and use, and may be referred to by other aerospace products. 1.3 Application guide 1.3.1 When preparing the model reliability work plan according to the requirements of this standard, the necessary work items shall be determined after tailoring the work items specified in this standard according to the product types, technical risks, use requirements, costs, schedule and other constraints. The reliability objectives specified by the products shall be achieved in the most cost-effective way. 1.3.2 In order to adapt to product characteristics and reliability assurance requirements, the content and implementation requirements of selected work items shall also be tailored, that is, the content and requirements that are not applicable and unnecessary to the products shall be deleted, certain conditions shall be modified or the technical requirements not included in this standard shall be supplemented, and the problems of duplication and inconsistency with other technical requirements shall be coordinated. 1.3.3 For general guidance on tailoring and applying the work items given in this standard and their contents and requirements, see Annex A (Informative), Table A1 "Implementation table of reliability work items".   2 Normative references GB/T 3187-94 Reliability and maintainability terms GJB 451-90 Reliability and maintainability terms GJB 768A-97 Guide to fault tree analysis GJB 813-90 Reliability modeling and prediction GJB 1027-90 Environmental test requirements for satellites GJB 1032-90 Environmental stress screening process for electronic products GJB 1391-92 Procedure for failure mode, effects and criticality analysis GJB 1909.1-94 Requirements of reliability and maintainability parameter selection and index determination for materiel - General GJB 1909.2-94 Requirements of reliability and maintainability parameter selection and index determination for materiel - Missile weapon systems GJB 1909.4-94 Requirements of reliability and maintainability parameter selection and index determination for materiel - Satellite GJB/Z 23-91 General requirements for preparing engineering reports of reliability and maintainability GJB/Z 27-92 Thermal design handbook for reliability of electronic equipment GJB/Z 34-93 The guidance of quantitative environmental stress screening on electronic product GJB/Z 35-92 Derating criteria for electrical, electronic and electromechanical parts GJB/Z 72-92 A guide to review for reliability and maintainability GJB/Z 102-97 Software reliability and safety design criteria GJB/Z 299A-89 Reliability prediction handbook for electronic equipment QJ 2145A-98 Assurance requirements for aerospace electronic, electrical and electromechanical devices QJ 2171A-98 Assurance requirements for aerospace product QJ 2437-93 Failure mode, effects and criticality analysis of satellite QJ 2668-94 Reliability design guidelines for aerospace products and reliability design guidelines for electronic products Interim provisions on reliability management of aerospace model products, Aviation Industry Corporation of China, Ltd., 1993 3 Definitions 3.1 Terms For the purposes of this standard, the definitions specified in GB/T 3187 and GJB 451 and the following apply. 3.1.1 reliability assurance all the systematic, planned and organized activities necessary to make people believe that the product meets the specified reliability requirements
