Organization: ASTM International
Publication Date: 1 February 2008
Status: inactive
Page Count: 6
ICS Code (Lubricants, industrial oils and related products): 75.100
significance And Use:

This laboratory test method can be used to quickly determine extreme pressure properties of lubricating oils at selected temperatures specified for use in applications where not only high-speed... View More

scope:

1.1 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 D 5706 for greases and differs regarding the stroke length and the cleaning solvent.

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 to use.
