This SAE Aerospace Information Report (AIR) reviews performance testing parameters for
non-cleanable, often referred to as disposable, filter elements utilized in aircraft power and propulsion
lubrication systems, including gas turbine engines, propulsion and transmission gear boxes, and
constant speed drives and integrated drive generators.
1.1 Purpose:
Performance testing is necessary to assure that filter elements retain their functional characteristics
under operating conditions. Variation in filter element testing methods and requirements make
comparison of performance test results difficult. In order to minimize these problems, this AIR
describes standard filter element performance test procedures, allowing both manufacturer and
customer a common means to specify, control, and evaluate filter elements. This document
highlights recommended tests and the appropriate test sequence. The methodology discussed
should be incorporated in filter element specifications.strRefField
