ASTM WK86025
Revision of D2596-20 Standard Test Method for Measurement of Extreme-Pressure Properties of Lubricating Grease (Four-Ball Method)
Rationale
The current test method does not include a speed ramp rate i.e. how long it takes to get 1770 r/min after the start button is pressed. It has been identified that some new machines take < 0.1 s whilst others take up to 1 s. The purpose f this revision is to standardize on a ramp rate / time to reach the test speed.
