Historical Standard: ASTM D2596-97(2008) Standard Test Method for Measurement of Extreme-Pressure Properties of Lubricating Grease (Four-Ball Method)
SUPERSEDED (see Active link, below)
ASTM D2596
1. Scope
1.1 This test method covers the determination of the load-carrying properties of lubricating greases. Two determinations are made:
1.1.1 Load-Wear Index (formerly called Mean-Hertz Load), and
1.1.2 Weld Point, by means of the Four-Ball Extreme-Pressure (EP) Tester.
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. Specific precautionary statements are given in 7.1 and 7.2.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
