Application Summary AI generated

This standard specifies destructive test methods for evaluating the bond strength between the bearing metal layer and the backing material in metallic multilayer plain bearings. It is applied in the manufacturing and quality control of sliding bearings used in engines, compressors, and other rotating machinery to ensure reliable adhesion under operational loads. The testing context involves mechanical separation techniques, such as shear or peel tests, to verify bond integrity during production or failure analysis.
