Designation: D 2440 99 Standard Test Method forOxidation Stability of mineral insulating Oil1 This Standard is issued under the fixed designation D 2440; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or Standard has been approved for use by agencies of the Department of This test Method determines the resistance of mineraltransformer oils to Oxidation under prescribed acceleratedaging conditions. Oxidation Stability is measured by thepropensity of oils to form sludge and acid products duringoxidation. This test Method is applicable to new oils, bothuninhibited and inhibited, but is not well defined for used orreclaimed A shorter duration Oxidation test for evaluation of inhibitedoils is available in Test Method D For those interested in the measurement of volatile acidity,reference is made to the work of IEC Subcommittee The values stated in metric units are to be regarded asthe Standard does not purport to address all of thesafety concerns, if any, associated with its use.
