Standard Test Method for Determining the Scuffing Temperature Limit of Lubricating Oils Using the SRV Test Machine

Importancia y uso:

5.1 This test method can be used to determine scuffing temperature limit and the evolution of coefficient of friction of lubricating oils with increasing temperatures for use in tribological contacts in which high-speed vibrational or start-stop motions are present for extended periods of time under initial high Hertzian line contact pressures. It has found application as a screening test for engine oils, gear lubricants and turbine oils. The test temperature may reach up to 300 °C. Users of this test method should determine whether results correlate with field performance or other applications. In comparison to the ball-on-disk geometry in accordance with Test Method D6425, the initial contact pressure is better retained over test time in this roller-on-disk geometry.
