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 18212;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.
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.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard information see 8 and Annex A2.
