Organization: ASTM
Publication Date: 1 October 2016
Status: active
Page Count: 7
ICS Code (Lubricants, industrial oils and related products): 75.100
scope:

This test method covers a procedure for determining extreme pressure properties of lubricating oils for hydraulics, gears, and engines under high-frequency linear-oscillation motion using the SRV test machine

NOTE 1-This test method was developed and the international round robin tests were jointly performed with the DIN 51834 working group. This procedure is based on the 2005 revision of Test Method D5706 for greases and differs regarding the stroke length and the cleaning solvent

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

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
