ASTM D3704 Test Method for Wear Preventive Properties of Lubricating Greases
ASTM D3704 Standard Test Method for Wear Preventive Properties of Lubricating Greases Using the (Falex) Block on Ring Test Machine in Oscillating Motion
4. Summary of Test Method
4.1 The tester is operated with a steel test ring oscillating against a steel test block. Test speed, load, angle of oscillation, time and specimen surface finish and hardness can be varied to simulate field conditions.
4.2 The width of the wear scar, developed on the test block from contact with the oscillating test ring, is measured.
5. Significance and Use
5.1 This test method is used to differentiate between greases having high, medium, and low wear preventive properties using oscillating motion. The user of this method should determine to his own satisfaction whether results of this test procedure correlate with field performance or other bench test machines.
