Purpose
Method for testing the load-carrying of lubricants, i.e. their suitability for lubricating those points, where, at mixed friction, steel slides on steel.
Brief description of the method
With this method, a given small amount of the lubricant to be tested is measured onto the friction wheel. The cylindrical test specimen is pressed with constant force on the friction wheel. The test is started when the friction wheel is set into rotation. The test duration is 30 s. The load-carrying capacity according to Brugger, measured in N/mm2, is the quotient of the pressure force the test specimen puts on the wheel and the value for the friction scar on the specimen, determined from tables provided with the machine.
