Downloadable datasets availableAnnotation ability available
This SAE Aerospace Recommended Practice (ARP) describes a method for evaluating the performance of filter elements designed for Aerospace hydraulic systems. The performance is measured and reported in terms of filtration ratios and stabilized contamination level while testing with cyclic flow.
Flow variations that occur in aircraft hydraulic systems are know to have a significant impact on filter performance. Current filter test procedures evaluate filter performance under steady flow conditions, and therefore, do not provide a measure of dynamic filter performance. ARP 4205 was developed to impose dynamic test conditions while measuring filter performance, to more closely simulate how a filter might perform on an operating aircraft.

A-6C1 Fluids and Contamination Control Committee
A6C1 is responsible for the development of standards, processes, and practices related to Aerospace Fluids and Systems' cleanliness in aerospace engines, hydraulic systems and missiles, and the integration of these components for Commercial and Military air vehicles. The panel provides a forum for government engineers, prime contractors, and suppliers to exchange technical information, regulatory updates, recent technology developments, issues related to system development and in service operation and lessons learned.
* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
