Scope:

This SAE Aerospace Recommended Practice (ARP) delineates two complementary filter element performance ratings: (1) dirt capacity, and (2) filtration efficiency, and corresponding test procedures. It is intended for non-cleanable (disposable), fine fuel filter elements used in aviation gas turbine engine fuel systems.

Variation in filter element testing methods and requirements make comparison of results difficult. In order to minimize these problems, this document describes standard filtration ratings and test procedures. Both manufacturer and customer will have a common means to specify, control, and evaluate filter elements.

Rationale:

The document is being revised for: (1) addition of references to jet fuels, (2) correction of one error in conversion units of gpm to lpm in para, 4., (3) clarification of some definitions in glossary of terms, (4) deletion of NIST SRM 2806 reference dust lot in para.1.3 since this is no longer the only reference lot. and deletion ofr references to Revision A, (5) revision of the test set-up for dirt capacity determination in fuel to include fuel recirculation (by-pass) loop, (6) revision of the test set-up to ensure homogeneous suspension of the test contaminant and minimize contaminant settling and variation in test results due to variations in test fuel, (7) improved definition of the system clean-up filter efficiency and coalescer water removal efficiency, (8) clarification of the amount of test contaminant to be used for validation of the dirt capacity test circuit, (9) editorial changes in para. 6.7.1.2, 6.7.1.5, 7.6(deleted), 7.10 for clarification of procedure.
