Scope
This SAE Aerospace Information Report (AIR) reviews performance testing parameters for fuel filter elements utilized in gas turbine engine and APU main fuel systems. The scope is limited to main fuel filter elements rated at 35 μm(c), or finer, which constitute the majority of contemporary engine main fuel system filtration. This document does not address icing tests specific to fuel filter elements since they are only required for certain engine designs and are custom test procedures. General information on icing tests for aircraft fuel system components can be found in ARP1401. This document also does not address fuel filter elements utilized in fuel hydraulic systems since it is outside the scope of this document,
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 fuel filter assembly. The testing discussed here is usually followed by laboratory and on-engine testing of the entire fuel filter assembly (including filter element, housing, valving, etc.) which is outside the scope of this AIR.
Rationale
The proper specification of filtration in gas turbine engine and APU main fuel systems is important in protecting fuel system components from particulate contamination that could lead to accelerated component wear, system malfunction and premature component failure. This AIR provides information about standard test procedures developed for the evaluation of the performance of fuel filter elements utilized in gas turbine engine and APU main fuel systems. This will allow both manufacturer and customer a common means to specify, control, and evaluate fuel filter elements to ensure that the filter elements retain their functional characteristics under operating conditions.

* 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.
