标准范围

ISO 8913:2006规定了在-55°C和204°C（-65°F和400°F）之间的温度和3000 psi（20684 kPa）或21000 kPa（3046 psi）的标称压力下用于飞机液压系统的轻质聚四氟乙烯（PTFE）软管组件的要求。软管组件也适用于在飞机气动系统中相同的温度和压力限制下使用，在该系统中，PTFE衬里上的一些气体可以通过壁扩散。不建议在高压气动存储系统中使用这些软管组件。此外，超过ISO 8913:2006规定限值的安装，或ISO 8913未具体涵盖的应用:2006年，例如氧气，需经买方批准。给出了符合ISO 8913:2006的软管组件采购标准清单。

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.
