Performance Evaluation of Fuel Filter Elements Utilized in Aircraft Gas Turbine Engine/APU Main Fuel Systems
Measuring Aircraft Gas Turbine Engine Fine Fuel Filter Element Performance
Performance Testing of Lubricant Filter Elements Utilized in Aircraft Power and Propulsion Lubrication Systems
This SAE Aerospace Information Report (AIR) reviews performance testing parameters for non-cleanable, often referred to as disposable, filter elements utilized in aircraft power and propulsion lubrication systems, including gas turbine engines and auxiliary power units (APUs), propulsion and transmission gear boxes, and constant speed drives and integrated drive generators (IDGs).
This document is confined to laboratory testing of filter element performance to qualify the filtration medium and filter element construction as opposed to qualification of the complete filter assembly. The testing discussed here is usually followed by laboratory and on-engine testing of the entire lube filter assembly (including filter element, housing, valving, etc.), which is outside the scope of this AIR.

Considerations for Ground Fault Interrupter (GFI) / Arc Fault Circuit Breaker (AFCB) for fuel pumps power circuit protection installation, specification and testing
Aircraft Engine Fuel Pump Cavitation Endurance Test
If any of the above conditions do not apply, refer to Section 2.
The procedure recommended herein is based on experience gathered by a number of laboratories conducting component qualification tests to MIL-E-5009, currently MIL-E-5007. It is intended to produce a uniform reproducible steady state test condition for fuel pump cavitation testing as required by various military engine specifications.
This test is not intended to establish altitude or climb rate, starting, or other transient performance of the article tested.
