This European Standard specifies a testing method and sets the acceptance criteria for the determining of the lubrication ability of lubricating greases intended for the lubrication of axle box bearings. The testing method is referred to in EN 12081. The lubricating ability, primarily related to the capability of lubricating greases to protect against wear, is determined in a roller bearing lubricant test rig. Wear of the rolling bearing rollers, the frictional behaviour and temperature during the test are used to discriminate between lubricating greases. The method is carried out in order to test axlebox greases for ordinary-speed vehicles, with speeds up to 200 km/h, and for greases intended for high-speed vehicles, with speeds up to 300 km/h. The method is a discriminating process, and accepted lubricating greases will be subject to more extensive performance tests according to EN 12082. For purpose of quality assurance and quality control, this test method is also used for batch testing of lubricating greases.
