Three laboratories have determined with different tribometers the friction coefficient of seven material couples under specified test conditions. Analysis of the results led to the following conclusions. The test geometry has no major influence on the friction coefficient, nor does the testing configuration. Load, speed and sometimes roughness have no major influence. The friction conditions changed during the test because of abrasion, and adhesion of abraded particles. Results obtained with steel are in good agreement with other recent reports. It is suggested that a couple made of hardened ball-bearing steel, which is of very constant quality world-wide, could serve as a reference couple to compare the frictional behaviour of different tribometers.
