This International Standard specifies a method for the determination of the resistance to oxidation under specified conditions of unused inhibited mineral turbine oils. The method is also applicable to other types of oil, such as hydraulic oil.

NOTE This method may be used for specification purposes, and is of value in estimating the oxidation stability of turbine lubricants in the laboratory. It should be recognized, however, that correlation between the results of any single method of test for oxidation stability and the stability of an oil in service will vary with service conditions.
