ASTM D1263 – Standard Test Method for Leakage Tendencies of Automotive Wheel Bearing Greases (Withdrawn 2010)
Description:
Significance and Use
The test method provides a screening device that permits differentiation among products having distinctly different leakage characteristics (Note 1). It is not the equivalent of longtime service tests, nor is it intended to distinguish between wheel bearing greases showing similar or borderline leakage.
Note 1—It is possible for skilled operators to observe significant changes in other important grease characteristics that occurred during the test. Such additional information can be of special interest to individual operators. The observations, however, are subject to differences in personal judgment among operators, and cannot be used effectively for quantitative rating.
Scope
1.1 This test method covers the evaluation of the leakage tendencies of wheel bearing greases when tested under prescribed laboratory conditions.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
