ASTM D7594-10 - 1.5.2010
 
1. Scope

1.1 This test method covers a procedure for determining the lubricating action of greases in order to prevent fretting wear under linear oscillation with associated low strokes and high Hertzian contact pressures under high-frequency linear-oscillation motion using the SRV test machine. By performing additional, nonmandatory extreme-pressure tests in accordance with Test Method D5706, the test grease should be shown to be able to withstand a Hertzian contact pressure of at least 2200 MPa without adhesive failure.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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.
