ASTM D2440 - 13 - Standard Test Method for Oxidation Stability of Mineral Insulating Oil

ASTM D2440 - 13

Standard Test Method for Oxidation Stability of Mineral Insulating Oil

Status : Current   Published : January 2013



1.1 This test method determines the resistance of mineral transformer oils to oxidation under prescribed accelerated aging conditions. Oxidation stability is measured by the propensity of oils to form sludge and acid products during oxidation. This test method is applicable to new oils, both uninhibited and inhibited, but is not well defined for used or reclaimed oils.

Note 1A shorter duration oxidation test for evaluation of inhibited oils is available in Test Method D2112.
Note 2For those interested in the measurement of volatile acidity, reference is made to IEC Method 61125.  2

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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.
