Significance and Use
Oxidation induction time, as determined under the conditions of this test method, can be used as an indication of oxidation stability. This test method can be used for research and development, quality control and specification purposes. However, no correlation has been determined between the results of this test method and service performance.
1.1 This test method covers the determination of oxidation induction time of lubricating greases subjected to oxygen at 3.5 MPa (500 psig) and temperatures between 155 and 210°C.
1.2 The values stated in SI units are to be regarded as 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.
