本文件确立了设计、分析、材料选择和表征的标准， 制造、测试和检查空间系统中的结构物项，包括有效载荷、航天器、， 上面的阶段，以及一次性和可重复使用的运载火箭。本标准在 特殊的太空系统将确保在太空的所有阶段实现安全、可靠的运行 任务。本文件特别适用于所有结构项目，包括断裂关键硬件 用于任务所有阶段的空间系统，但以下例外:自适应 结构、发动机、固体火箭喷嘴和热防护系统。

This document establishes a standard for the design, analysis, material selection and characterization, fabrication, test, and inspection of structural items in space systems, including payloads, spacecraft, upper-stages, and expendable and reusable launch vehicles. This standard, when implemented on a particular space system, will assure high confidence in achieving safe, reliable operation in all phases of the mission. This document applies specifically to all structural items including fracture-critical hardware used in space systems during all phases of the mission - with the following exceptions: adaptive structures, engines, solid rocket nozzles, and thermal protection systems.
