ASTM D4170 – Fretting Wear Protection by Lubricating Greases

We perform grease quality testing by ASTM D4170 to evaluate the fretting wear protection provided by lubricating greases. Fretting wear occurs in oscillating bearings. This test has been used to predict the fretting performance of greases in passenger car wheel bearings when shipped long distances.

We also perform wear testing by ASTM D2882, ASTM D3704, FTM 335, and MIL-G-81827 §4.7.3. These different test methods use different instruments or procedures or are used for certain sample types. Click on the test method number to learn more about each test.
