ASTM D1831 - Roll Stability of Lubricating Grease
Significance and Use
5.1 The roll stability test is widely used in specifications. Test results are significant insofar as they can show a directional change in consistency that could occur in service. No accurate correlation is established between the test results and shear stability in actual service.
1.1 This test method covers determination of the changes in the consistency, as measured by cone penetration, of lubricating greases when worked in the roll stability test apparatus.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.Extracted, with permission, from ASTM D1831-20 - Roll Stability of Lubricating Grease, copyright ASTM International, 100 Barr Harbor Drive, West Conshohocken, PA 19428.
