Friction tests are carried out by using a four-ball machine, a compression-twist type friction testing machine, a strip-ironing type friction testing machine and a cup deep drawing apparatus which are representative of fundamental friction tests, fundamental friction tests for metal forming, simulative friction tests and tests in practical users respectively. The lubricants used are several mineral oils oiliness agents and extreme pressure additives. Correlations among the Evaluation Measures Gained are studied. It has been clarified that the measures gained are studied it has been clarified that the measures show a good correlation in cases where the test pieces have a similar surface appearances after friction sliding against each other.
