Method for judging quality of frictional pairings in mechanical engineering, involves determining critical contact pressure with regard to friction pairing so as to determine significant structural damage on friction surfaces
The method involves bringing a reference frictional surface (6) with a test friction surface (7) of a disk shaped specimen (2), where the reference frictional surface is allowed to only partially cover the test friction surface. A lubricant is supplied between the frictional surface and the test friction surface. The specimen is moved relative to the specimen such that the friction surfaces rub with each other. A critical contact pressure with regard to the friction pairing is determined so as to determine significant structural damage on the friction surfaces during continuous operation.
