Plain bearings. Testing of the tribological behaviour of bearing materials - Testing of polymer-based bearing materials1 Scope This part of ISO 7148 specifies tribological tests of polymer based plain bearing materials under specified working conditions, i. e. load, sliding velocity and temperature, with and without lubrication. From the test results, data are obtained which indicate the relative tribological behaviour of metal polymer and polymer polymer rubbing parts. The purpose of this part of ISO 7148 is to obtain, for polymer material combinations used in plain
