ASTM D3527 – Standard Test Method for Life Performance of Automotive Wheel Bearing Grease
Description:
Significance and Use
5.1 This test method differentiates among wheel bearing greases having distinctly different high-temperature characteristics. It is not the equivalent of longtime service tests, nor is it intended to distinguish between the products having similar high-temperature performance properties.
5.2 This test method has proven to be helpful in screening greases with respect to life performance for automotive wheel bearing applications.
Scope
1.1 This test method covers a laboratory procedure for evaluating the high-temperature life performance of wheel bearing greases when tested under prescribed conditions.
Note 1: Changes to this test method in the 1985 revision increased test severity. Results will not be comparable with data from earlier procedures.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.2.1 Exception—Apparatus dimensions in inches are to be regarded as the standard.
