Summary This standard specifies the method for determining the anti-wear properties of lubricating oil using a four-ball tester. This standard is applicable to the evaluation of the anti-wear performance of lubricating oils, including three test conditions A, B and C. Among them, test condition C is mainly used to evaluate the anti-wear performance of industrial closed gear oil L-CKD, and can also be used to evaluate other lubrication. The wear resistance of the oil. A method for evaluating the wear resistance of grease using the same test machine is described in detail in SH/T 0204.
