ASTM D117 - Sampling, Test Methods, and Specifications for Electrical Insulating Oils of Petroleum Origin
We perform quality and conformance testing on insulating oils by a variety of methods and specifications, including methods outlined by ASTM D117. ASTM D117 is a guide describing methods of testing and specifications for electrical insulating oils of petroleum origin used in electrical cables, transformers, oil circuit breakers, and other electrical apparatus where the oils are used as insulating, or heat transfer media, or both. This guide outlines the applicability of the available test methods. When more than one test method is available for measuring a given property, ASTM D117 describes their relative advantages, laboratory convenience, precision, and applicability to specific types of electrical insulating oils.
