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 axlebox bearings. 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.
NOTE 1 The testing method is referred to in EN 12081.
The method described 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 those greases that pass will be subject to more extensive performance tests.
NOTE 2 In EN 12082 a more extensive rig performance test is described in detail. This rig performance test will check the satisfactory function of the assembly of box housing, bearing, sealing and grease during a simulated journey.
For purpose of quality assurance and quality control, this test method is also used for batch testing of greases intended for use in axleboxes.
For light rail and tramway applications other standards or documents agreed between the customer and the supplier may be applied.
