Bibliography

Provides requirements for aramid reinforced lightweight polytetrafluoroethylene (PTFE) hose assemblies for use in aircraft hydraulic, oil and fuel systems at temperatures between -55 degree C and 135 degree C (-65 degree F and 275 degree F) and at a nominal pressure of 21000 kPa (210 bar) (3046 psi) or 20684 kPa (3000 psi).

This International Standard specifies requirements for aramid reinforced lightweight polytetrafluoroethylene (PTFE) hose assemblies for use in aircraft hydraulic, oil and fuel systems at temperatures between−55°C and 135°C (−65 °F and 275 °F) and at a nominal pressure of 21000kPa (210 bar) (3046 psi) or 20684kPa (3000 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 of the PTFE liner may be tolerated.
