Scope:

This Aerospace Standard (AS) defines the requirements for a heavy braid polytetrafluoroethylene (PTFE) lined, metallic reinforced, hose assembly suitable for use in high temperature, 400 °F, high pressure, 3000 psi, aircraft hydraulic fluid systems, also for use in pneumatic systems which allow some gaseous diffusion through the PTFE wall. The -20 size operating temperature is limited to 275 °F maximum.

Rationale:

Added periodic testing requirements for fire resistant hose assemblies. Relocated fire test qualification requirements from NOTES paragraph 6.1.1 to qualification testing paragraphs 3.5.2.14 and 4.6.16, and revised Tables 4A and 4B to reflect applicable fire test paragraph.
