ASTM D2782 - Extreme-Pressure Properties of Lubricating Fluids (Timken Method)

Significance and Use

5.1 This test method is used widely for the determination of extreme pressure properties for specification purposes. Users are cautioned to carefully consider the precision and bias statements herein when establishing specification limits.

Scope

1.1 This test method covers the determination of the load-carrying capacity of lubricating fluids by means of the Timken Extreme Pressure Tester.

NOTE 1—This test method is suitable for testing fluids having a viscosity of less than about 5000 cSt (5000 mm2/s) at 40 °C. For testing fluids having a higher viscosity, refer to Note 5 in 9.1.
