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.
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.

* 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.
