ASTM D2240 - Oxidation Stability of Mineral Insulating Oil

We perform mineral oil testing by ASTM D2440 to determine the oxidation stability of mineral transformer oils under accelerated aging conditions. Oxidation stability is measured by the propensity of oils to form sludge and acid products during oxidation. Good oxidation stability is necessary in order to maximize the service life of insulating oil by minimizing the formation of sludge and acid. 

We also perform oxidation stability testing by ASTM D2112ASTM D2272ASTM D2274ASTM D525ASTM D7462ASTM D873ASTM D942ASTM D943DIN 51587EN 15751IP 142IP 388IP 40ISO 12205ISO 4623, and ISO 7536. These different test methods use different instruments or procedures or are used for certain sample types.
