Significance and Use | ||
5.1 This test method, used for specification purposes, differentiates between lubricating greases having low, medium, and high level of extreme-pressure properties. The results do not necessarily correlate with results from service.5.2 It is noted that lubricating greases that have as their fluid component a silicone, halogenated silicone, or a mixture comprising silicone fluid and petroleum oil, are not applicable to this method of test. |
||
1. Scope | ||
1.1 This test method covers the determination of the load-carrying properties of lubricating greases. Three determinations are made: 1.1.1 Load-Wear Index (formerly called Mean-Hertz Load), 1.1.2 Weld Point, by means of the Four-Ball Extreme-Pressure (EP) Tester, and 1.1.3 Last nonseizure load (LNSL). 1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only. 1.3 This 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. |
