Product Code:SAE MAP749
Title:Aircraft Turbine Engine Fuel System Component Endurance Test Procedure (Room Temperature Contaminated Fuel)
Issuing Committee:Ae-5b Engine Related Components Airframe-Mounted Pumps
Scope:This recommended practice describes a method for conducting room temperature, contaminated fuel, endurance testing when the applicable specification requires nonrecirculation of the contaminants. The objective of the test is to determine the resistance of engine fuel system components to wear or damage caused by contaminated fuel operation. It is not intended as a test for verification of the component's filter life. ARP1827 is recommended for filter evaluation.
