Description / Abstract:
This SAE Aerospace Standard (AS) establishes the requirements
for polytetrafluoroethylene (PTFE) hose assemblies for use in
aerospace hydraulic systems at temperatures between -55 °C and 204
°C and at a nominal pressure up to 28,000 kPa (280 bar). The hose
assemblies are also suitable for use within the same temperature
and pressure limitations in aerospace 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 herein are exceeded, or in which the
application is not covered specifically by this document, for
example, oxygen, shall be subject to the approval of the
purchaser.
Classification:
Hoses covered by this document shall be of temperature, types
and pressures classes covered in MA2001 (ISO 6771).
