SAE AS5752 – Aerospace – Visual Inspection Standard for Elastomeric Sealing Elements Other than O-Rings

This standard provides the following: a. The required surface finish criteria for the designed function of the parts; b. The definition of surface imperfections and defects that affect surface quality; c. 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: T-Seals; L-Rings; Capped T Rings; Capped L Rings; Cammed Type Seals; Cruciform Shaped Elastomers; Pyramid (Dyna-Bak) Seals; Square Ring Seals; Quadruple Lobed Seals; U-Cups; Spring Energized U-Cups; Molded in Place Metal Gasket Seals
