适用范围：This International Standard specifies requirements for standard-weight polytetrafluoroethylene (PTFE) 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 (210 bar). 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 can 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 this International Standard are exceeded, or in which the application is not covered specifically by this International Standard, for examplefor oxygen, shall be subject to the approval of the purchaser.
