Fire Testing of Flexible Hose, Tube Assemblies, Coils, Fittings, and Similar System Components
|Publication Date:||1 October 2017|
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, Polytetrafluoroethyl
Type IIb - Hose Assembly, Polytetrafluoroethyl
Type IIc - Hose Assembly, Polytetrafluorethyle
Type IIIa - Rigid Tubing Assembly - Fuel and Oil Systems
Type IIIb - Rigid Tubing Assembly - Hydraulic Systems
Type IIIc - Rigid Tubing Assembly - Zero Flow Systems
