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 ¿¿m(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,
