Significance and Use
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. No other units of measurement are included in this standard.
1.2.1 Exception—The values stated in inch-pound units for the apparatus dimensions are to be regarded as standard; the SI conversions are provided 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.
