Cancels and replaces the first edition (1990). Specifies requirements for polytetrafluoroethylene hose assemblies for use in aircraft hydraulic systems at temperatures between -55 °C and +204 °C and at a nominal pressure up to 28 000 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.
