List of references
Defines requirements for unused and reclaimed oxidation inhibited and uninhibited mineral insulating oils, to be used in transformers, switchgear and similar electrical equipment where oil is needed as an insulant or for heat transfer. Not applicable to mineral insulating oils for use as impregnates in cables or capacitors, nor to hydrocarbon insulating liquids obtained by synthesis.
