1.1This test method covers the determination of the load-carrying properties of lubricating greases. Three determinations are made:

1.1.1Load-Wear Index (formerly called Mean-Hertz Load), and

1.1.2Weld Point, by means of the Four-Ball Extreme-Pressure (EP) Tester.

1.1.3Last nonseizure load (LNSL).

1.2The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.

1.3This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
