This test method is used to determine the property of lubricants by measure the pa-rameters such as the coefficient of friction, wear value and seizure load on the Four Ball Wear TestMachine. Experiments were conducted using ASTM D5183-95 Standard Test Method (StandardTest Method For Determination Of The Coefficient of Friction of Lubricants Using the Four BallWear Test Machine) to measure the friction reducing ability , antiwear property and ex-treme-pressure property of different type of lubricants, the additives are also been studied at thesame time. From the test result, this test method can distinguish not only the property of differenttype of lubricants rapidly, sensitively and effectively but also can reflect the friction reducingability , antiwear property and extreme-pressure property of various additive formula.
