Description / Abstract:

This SAE Aerospace Standard (AS) establishes uniform requirements and procedures for the fire testing of flexible hose assemblies and rigid tube assemblies (including coiled tubes) to be used in aircraft or aerospace vehicle fluid systems. These procedures may also be followed for fire tests on other piping components as specified by the customer. It also refers to standard fire test equipment to be used in conducting "referee" fire tests.


Component assemblies shall be designated by Type and Class according to fire test duration and usage. Flame test apparatus and temperature shall be the same for each Type and Class.


Type Ia - Hose Assembly, Rubber - Fuel and Oil Systems

Type Ib - Hose Assembly, Rubber - Hydraulic Systems

Type Ic - Hose Assembly, Rubber - Zero Flow Systems

Type IIa - Hose Assembly, Polytetrafluoroethylene - Fuel and Oil Systems

Type IIb - Hose Assembly, Polytetrafluoroethylene - Hydraulic Systems

Type IIc - Hose Assembly, Polytetrafluorethylene - Zero Flow Systems

Type IIIa - Rigid Tubing Assembly - Fuel and Oil Systems

Type IIIb - Rigid Tubing Assembly - Hydraulic Systems

Type IIIc - Rigid Tubing Assembly - Zero Flow Systems
