This SAE Aerospace Recommended Practices (ARP) delineates two complementary filter element performance ratings: (1) dirt capacity, and (2) filtration efficiency, and correpsonding test procedures. It is intended for the noncleanable (disposable), fine fuel filter elements used in aviation gas turbine engine systems.
Variation in filter element testing methods and requirements make comparison of results difficult. In order to minimize these problems, this ARP describes standard filtration ratings and test procedures. Both manufacturer and customer will have a common means to specify, control, and evaluate filter elements
