Scope:

This test method provides procedures for exposing specimens of elastomer materials (AS 568-214 size O-rings) representative of those used in gas turbine engines to lubricants or reference fluids under defined time and temperature conditions. This test includes both suspended and compressed O-rings. Resultant changes in the O-ring’s physical properties (tensile strength, elongation, hardness, mass, volume, and compression set) are measured to determine the amount of deterioration of the elastomer.

Rationale:

This SAE Aerospace Recommended Practice is intended to provide acceptable procedures for qualification purposes to determine the compatibility of aviation propulsion system grade elastomers with the aviation lubricants that they may be exposed to during service, such as the proposed MIL-PRF-23699 EE class. Properties of such elastomeric materials may deteriorate during exposure to aviation lubricants, thereby affecting their performance capabilities and potentially result in part failure.
