Scope

This standard specifies the method of determining the bearing capacity of lubricants using a four-ball extreme pressure tester, including the determination of three indicators: maximum no-stick load (PB), sintering load (PD), and comprehensive wear value (ZMZ).
This standard applies to lubricants. In practical applications, different evaluation indicators can be selected according to the different uses of lubricants.
