Significance and Use | ||||||||
It is known that contamination by water can affect the shear stability of some greases in service. Both test procedures specified in this method are widely used to determine the wet shear stability of greases in service. Many grease specifications require these procedures as a wet shear stability test. No accurate correlation is established between the test results and wet shear stability of grease in actual service. |

1. Scope | ||||||||
1.1 This test method covers two procedures for determining the shear stability of lubricating grease in the presence of water (wet shear stability) by a full scale grease worker or a roll stability test apparatus. Both procedures can be used to determine the relative wet shear stability of greases, but the results between procedures are not directly comparable. This test method is also known as the water stability test. 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. |
