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 D5706 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 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.
