Safety assurance requirements for aerospace products
1 Scope
1.1 Subject content
This standard specifies the general requirements, work items and implementation requirements for safety assurance of aerospace products.
1.2 Application scope
This standard is applicable to various stages of spacecrafts and carrier rockets (including ground equipment) such as feasibility demonstration, scheme, engineering development (prototype, test prototype or flight model) and use, and may be referred to by other aerospace products.
1.3 Application guide
1.3.1 When preparing the product safety work plan according to the requirements of this standard, the work items specified in this standard shall be tailored according to the national and aerospace safety regulations and contract requirements, as well as product types, technical risks, use requirements and other constraints, and the necessary work items shall be determined to achieve the specified safety objectives of the product in the most economical and effective way.
1.3.2 In order to adapt to the characteristics and safety assurance requirements of the product, the contents and implementation requirements of selected work items shall also be tailored, that is, the contents and requirements that are not applicable and necessary to the product shall be deleted, the technical requirements not included in this standard shall be revised or 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 "Application table of system safety work items".
