Oxidation Stability – Mineral Insulating Oils

ASTM D2440 IP 307 (obs) ISO 7624 OXIDATION STABILITY OF MINERAL INSULATING OIL
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.

IP 48 DETERMINATION OF OXIDATION CHARACTERISTICS OF LUBRICATING OIL
This method indicates the tendency of a lubricating oil to deteriorate on oxidation under specified conditions.

IP 280 PETROLEUM PRODUCTS AND LUBRICANTS – INHIBITED MINERAL TURBINE OILS – DETERMINATION OF OXIDATION STABILITY
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.

IP 306 DETERMINATION OF OXIDATION STABILITY OF STRAIGHT MINERAL OIL
This method is designed to give a measure of the tendency of straight (i.e. plain) mineral lubricating oil to oxidise under specified conditions.

EN 61125-B TEST FOR EVALUATING THE OXIDATION STABILITY OF UNUSED INHIBITED MINERAL INSULATING OILS BY MEASUREMENT OF THE INDUCTION PERIOD.

EN 61125-C TEST FOR EVALUATING THE OXIDATION STABILITY OF UNUSED HYDROCARBON BASED INSULATING LIQUIDS UNDER ACCELERATED CONDITIONS REGARDLESS OF WHETHER OR NOT ANTIOXIDANT ADDITIVES ARE PRESENT
