(What is a Work Item? / How to Input to a Work Item)

Work Item: ASTM WK24720 - New Test Method for Determining Fretting Wear Resistance of Lubricating Greases Under High Hertzian Contact Pressures Using a High-Frequency, Linear-Oscillation (SRV) Test Machine


Developed by Subcommittee: D02.G0.04 | Committee D02 Home | Contact Staff Manager



1. Scope

1.1 This test method covers a procedure for determining the lubricating action of greases 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 according to Test Method D 5706 conduct to a meaningful screening of the tribological performance (friction and wear response) of a grease to be expected under fretting conditions. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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 the use. Maintenance-free aircraft require next generation antifretting greases with much lower wear rates. Some for automotive in view of lifetime lubrication.
