Omfang

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 and auxiliary power units (APUs), propulsion and transmission gear boxes, and constant speed drives and integrated drive generators (IDGs). 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 filter assembly. The testing discussed here is usually followed by laboratory and on-engine testing of the entire lube filter assembly (including filter element, housing, valving, etc.), which is outside the scope of this AIR. Purpose Performance testing is necessary to assure that filter elements retain their functional characteristics under operating conditions. Variations 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 lubricant filter elements. This document highlights recommended tests and the appropriate test sequence. The methodology discussed should be incorporated in filter element specifications.
