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.


5.1 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 vibrational or start-stop motions are present with high Hertzian point contact. This test method has found wide application in qualifying lubricating oils used in constant velocity joints of front-wheel-drive automobiles, gear-hydraulic circuit, rear axles, gears and engine components. Users of this test method should determine whether results correlate with field performance or other applications.
