标准摘要
[中文适用范围]： 本国际标准规定了用于飞机液压系统的轻质聚四氟乙烯 (PTFE) 软管组件的要求，温度范围为 − 55 °C 至 204 °C（− 65 °F 至 400 °F），公称压力高达 3 000 psi (20 684 kPa) 或 21 000 kPa (3 046 psi)。 该软管组件还适合在飞机气动系统中相同的温度和压力限制下使用，其中可以容忍一些气体通过 PTFE 衬里的壁扩散。 不建议在高压气动存储系统中使用这些软管组件。 此外，超出本国际标准规定的限值的安装，或本国际标准未具体涵盖的应用（例如氧气）的安装，须经买方批准。 附件A是符合本国际标准的软管组件采购标准清单。 [外文原描述]： ISO 8913:2006 specifies requirements for lightweight polytetrafluoroethylene (PTFE) hose assemblies for use in aircraft hydraulic systems at temperatures between - 55 °C and 204 °C (- 65 °F and 400 °F), and at a nominal pressure up to 3 000 psi (20 684 kPa) or 21 000 kPa (3 046 psi). The hose assemblies are also suitable for use within the same temperature and pressure limitations in aircraft pneumatic systems where some gaseous diffusion through the wall on the PTFE liner may be tolerated. The use of these hose assemblies in high-pressure pneumatic storage systems is not recommended. In addition, installations in which the limits specified in ISO 8913:2006 are exceeded, or in which the application is not covered specifically by ISO 8913:2006, for example for oxygen, are subject to the approval of the purchaser. A listing of hose assembly procurement standards conforming to ISO 8913:2006 is given.
