Fire Testing of Fluid Handling Components for Aircraft Engines and Aircraft Engine Installations
AS4273A
This document establishes requirements, test procedures, and acceptance criteria for the fire testing of fluid handling components and materials used in aircraft fluid systems. It is applicable to fluid handling components other than those prescribed by AS1055 (e.g., hoses, tube assemblies, coils, and fittings).
It also is applicable to materials, wiring, and components such as reservoirs, valves, gearboxes, pumps, filter assemblies, accumulators, fluid-cooled electrical/electronic components, in-flight fluid system instrumentation, hydromechanical controls, actuators, heat exchangers, and manifolds. These components may be used in fuel, lubrication, hydraulic, or pneumatic systems.
Rationale:
This SAE Aerospace Standard (AS) presents an improved fire test procedure sequence and changes to meet the new FAA requirements specified in AC 33.17 and AC 20-135.
