This standard specifies a method for the estimation of the oxidation stability of unused turbine oils having the same composition (base stock and additives) and for controlling the continuity of this property from batch to batch.

NOTE 1 - The method is not intended to be used to estimate the service life of new oils, especially those of varying compositions, nor is not intended to be a substitute or a replacement for any method for determining the oxidation characteristics of inhibited mineral turbine oils, or a rapid means of estimating the results to be obtained from such methods.

NOTE 2 - The method can be used for estimating the remaining oxidation test life of in service mineral turbine oils by comparison of the result obtained with that for the new oil.
