This SAE Aerospace Recommended Practice (ARP) delineates two complementary filter element performance parameters: (1) dirt capacity, and (2) filtration efficiency, and corresponding test procedures. It is intended for non-cleanable (disposable), fine fuel filter elements, rated at 25 µm(c) or finer, used in aviation gas turbine engine fuel systems.
The proper performance of the engine fuel filter element is important in protecting engine fuel system components from particulate contamination that could lead to accelerated component wear, fuel system malfunction, and premature component failure. This SAE Aerospace Recommended Practice (ARP) provides a standard test method for determining the filtration efficiency and dirt capacity of engine main fuel filter elements. This will allow both manufacturer and customer a common means to evaluate the performance of engine main fuel filter elements.
The standard has been revised to: (1) clarify the scope in terms of the applicability of the procedure to fuel filter elements rated at 25 µm(c) or finer, (2) include an update on the current status of the standard reference material (SRM) used for calibration of automatic particle counters per ISO 11171, (3) update the dirt capacity test setup validation procedure for clarity and to include the option of using a suitable validation filter element, (4) specify periodic determination of the water content in the jet fuel during the dirt capacity test, and (5) include editorial changes for clarity.

* 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.
