This document discusses the relative merits of the physical and chemical properties of hydraulic fluids in relation to the aerospace hydraulic system design, and the related materials compatibility. The discussion in this report applies both to hydrocarbon and phosphate ester based aircraft hydraulic fluids. In some cases, numerical limits are suggested, but, in general, the significance and effect of a property is noted qualitatively.
The update implements multifold revisions to the document. The title was changed to describe better the content of the document, which discusses the significance and relevance of aircraft hydraulic fluid properties, rather than being an compilation of typical fluid properties. Scope was extended to include phosphate ester hydraulic fluids used in commercial aircraft. Referenced test methods and property descriptions were updated, where appropriate. Sections that did not relate to physical and chemical properties of aircraft hydraulic fluids were deleted.

A6C3 is responsible for the development of standards, processes, and practices related to the hydraulic fluids used in both Commercial and Military air vehicles. The panel provides a forum for aircraft manufacturers, suppliers, airworthiness regulatory engineers and operators 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.
