    This paper provides a review of two specifications for electrical insulating mineral oils by ASTM and the International Electrotechnical Commission (IEC). The physical, electrical, and chemical properties of these fluids are specified for use in electric apparatus such as transformers. The specified test methods are compared and their differences are presented. Some properties of commercial oils are shown.
