Oxidation Stability of Mineral Insulating Oil
ASTM D2440
IP 280
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.
