ASTM D2893 - Oxidation Characteristics of Extreme-Pressure Lubrication Oils
Significance and Use
4.1 These test methods have been widely used to measure the oxidation stability of extreme pressure lubricating fluids, gear oils, and mineral oils.
1.1 These test methods (A and B) cover the determination of the oxidation characteristics of extreme-pressure fluid lubricants, gear oils, or mineral oils.
NOTE 1: The changes in the lubricant resulting from these test methods are not always necessarily associated with oxidation of the lubricant. Some changes may be due to thermal degradation.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.Extracted, with permission, from STM D2893-19 - Oxidation Characteristics of Extreme-Pressure Lubrication Oils, copyright ASTM International, 100 Barr Harbor Drive, West Conshohocken, PA 19428.
