Downloadable datasets availableAnnotation ability available
This standard provides the following:
The required surface finish criteria for the designed function of the parts
The definition of surface imperfections and defects that affect surface quality
The categories by location for each geometry for the permissible type, size and quantity of defects
It also establishes the quantitative levels of acceptance by providing defined limits and inspection guidance for the acceptance or rejection of production parts
This specification is applicable but not limited to, the surface quality of:
Capped T Rings
Capped L Rings
Cammed Type Seals
Cruciform Shaped Elastomers
Pyramid (Dyna-Bak) Seals
Square Ring Seals
Quadruple Lobed Seals
Spring Energized U-Cups
Molded in Place Metal Gasket Seals
AS5752 has been reaffirmed to comply with the SAE five-year review policy.

A6C2 is responsible for the development of standards, processes, and practices related to Seals, Scrapers and Bearings used in actuation systems for Commercial and Military air vehicles. The panel provides a forum for government engineers, prime contractors, OEMs 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.
