ASTM D2596, Standard test method for measuring Extreme-pressure properties of lubricating grease, (K10800 Four Ball Wear and EP Tester, which measures relative wear-preventing properties of lubricating fluids and greases in sliding and rolling applications. Performs both wear preventative (WP) and extreme pressure (EP) analysis on lubricating greases.)
1.1 This test method covers the determinations 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.
1.2 The values stated in SI units are to be regarded as the standard The values in parentheses are for informations only.
1.3 The standard does not purport to address all of the safety concerns, if any, associated with its uses. 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.
