标准范围

取消并替换第一版(1989年)。规定了在-55°C至+204°C的温度和高达21 000 kPa的标称压力下用于飞机液压系统的标准重量聚四氟乙烯软管组件的要求。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,在这些系统中,可以允许一些气体通过PTFE衬里的壁扩散。这些软管组件在高压环境中的使用-不建议使用压力气动存储系统。

Cancels and replaces the first edition (1989). Specifies requirements for standard-weight polytetrafluoroethylene hose assemblies for use in aircraft hydraulic systems at temperatures between -55 °C and +204 °C and at a nominal pressure up to 21 000 kPa. 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 of the PTFE liner may be tolerated. The use of these hose assemblies in high-pressure pneumatic storage systems is not recommended.
