ASTM D5483 - Oxidation Induction Time of Lubricating Greases by Pressure Differential Scanning Calorimetry

Significance and Use

5.1 Oxidation induction time, as determined under the conditions of this test method, can be used as an indication of oxidation stability.3 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.

Scope

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 °C and 210 °C.

1.2 Warning—The original data published in Research Re-port RR:D02-1314, was not analyzed in accordance the current D2PP. It also used instruments which are no longer manufactured and in a check of currently used instruments, none of the original instruments were still in use. The new precision of this test method is still to be established.
