SAE ARP1797 Revision A, April 1, 1999
Aircraft and Aircraft Engine Fuel Pump Low Lubricity Fluid Endurance Test
Description / Abstract:
This procedure is intended to apply to fuel pumps.
This procedure will be defined in terms of recommended test fluid, test setup, test conditions, and test method.
This procedure may be used for other fuel system components, by testing in conjunction with the pump, which normally supplies the component inlet flow, or a substitute test pump of similar capacity.
This procedure may be used, with variations in test conditions and test fluid for performing pump evaluation tests. Tests at progressively increasing pump speeds and pressures will provide design limitation data. Alternate test periods on a test pump and another pump, of a design for which actual service durability is known, will provide useful comparison data.
Purpose:
This recommended practice defines procedures for testing aircraft and aircraft engine fuel pumps to ensure their operability with respect to low lubricity fuels. This is achieved by verification testing on a standard low lubricity test fluid. This procedure is intended to produce a uniform reproducible test condition for fuel pump endurance testing using low lubricity fluid, to provide a common reference for endurance capability. Pump endurance capability is to be established in terms of internal parts wear and change in pump performance. Pass/fail criterion are normally established by the purchasing authority. This document is not a pump qualification test procedure.
