Scope
This SAE Aerospace 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 performance and service life. ARP1827 is recommended for filter performance evaluation.
Rationale
This document has been revised to: (1) Update and clarify the references. (2) Clarify that the test system schematics depict pumps as the test components, although other components may be tested by locating them downstream of a test system pump. (3) Replace NAS 1638 by the more contemporary AS4059 for fluid cleanliness levels (Table I of AS4059 is the same as the NAS 1638 cleanliness levels). (4) Update Figures 1 and 2 to conform to modern hydraulic circuit symbols and to be consistent. (5) Replace the facility filter specification MIL-F-27656 by MIL-PRF-81836 specification. (6) Delete 3.7.2, referencing gravimetric analysis of samples from the pump by-pass loop, since it is out of context in this location. (7) Clarify sampling for gravimetric analysis in 10.3. (8) Editorial changes for clarity.
MAP749C has been reaffirmed to comply with the SAE Five-Year Review policy.

AE-5B Aircraft and Engine Fuel and Lubricant Sys Components
Welcome to the AE-5B, Aerospace Fuel, Inerting and Lubriation Systems public forum area.
Scope: Has responsibility for the resolution of problems in either design or service usage of aerospace fuel, oil and oxidizer systems, their components such as valves, pumps, couplings, fuel cells, quantity and flow gages, and tanks, and related problems as presure surger, icing, electrification, and safety. Develops standards addressing fuel, oil and oxidizer systems.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
