Description

ASTM D2782-02-Reapproved2008

Historical Standard: Standard Test Method for Measurement of Extreme-Pressure Properties of Lubricating Fluids (Timken Method)

ASTM D2782

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.

1.2 The values stated in SI units are to be regarded as standard. Because the equipment used in this test method is available only in inch-pound units, SI units are omitted when referring to the equipment and the test specimens.

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 warning statements are given in 7.1, 7.2, 8.1, 8.2, 9.4, and 9.9.
