本文件确立了航天飞行压力部件设计、制造和测试的基线要求。它还规定了航天器和运载火箭压力系统的组装、安装、测试、检查、操作和维护要求。这些要求在特定空间系统上实施时，可确保实现安全可靠运行的高度信心。 本文件适用于压力系统中除压力容器和加压结构以外的所有压力部件。它包括管路、配件、阀门、波纹管、软管和其他适当的部件，这些部件集成在一起形成一个压力系统。 ISO？14623规定了压力容器和加压结构的要求。 本文件不适用于发动机部件。

This document establishes the baseline requirements for the design, fabrication and testing of space flight pressure components. It also establishes the requirements for the assembly, installation, test, inspection, operation and maintenance of the pressure systems in spacecraft and launch vehicles. These requirements, when implemented on a particular space system, ensure a high level of confidence in achieving safe and reliable operation. This document applies to all pressure components other than pressure vessels and pressurized structures in a pressure system. It covers lines, fittings, valves, bellows, hoses and other appropriate components that are integrated to form a pressure system. The requirements for pressure vessels and pressurized structures are set forth in ISO？14623. This document does not apply to engine components.
