Aerospace - Evaluation of Particulate Contamination in Hydraulic Fluid - Membrane Procedure
STANDARD published on 1.1.2025
Designation standards: SAE ARP4285A
Publication date standards: 1.1.2025
Country: American technical standard
Category: Technical standards SAE
This SAE Aerospace Recommended Practice (ARP) establishes a method for evaluating the particulate matter extracted from the working fluid of a hydraulic system or component using a membrane. The amount of particulate matter deposited on the membrane due to filtering a given quantity of fluid is visually compared against a standard membrane in order to provide an indication of the cleanliness level of the fluid.
