    Abstract

    ASTM Committee D-27 on Electrical Insulating Fluids and Gases was formed as Subcommittee IV under Committee D-9 in the year 1916 and was designated as a separate technical committee in 1959. The scope of D-27 is the promotion of knowledge pertaining to insulating liquids and gases, whether synthetic or natural in origin, and the recommendation of standards and specifications pertinent to these materials.

    The principal materials included in this arena are oils of petroleum origin, synthetic liquids, and halogenated and other gases when used singularly or as combinations, as electrical insulation or as an environment for electrical insulation in transformers, capacitors, and other electrical equipment.

    Standards peculiar to solid insulating materials and varnishes, and the development of standards pertaining to non-electrical uses of liquids and gaseous materials are excluded from our scope.

    The D-27 membership is made up of technical people from the refining and chemical industries, electrical equipment manufacturers, electrical utilities, and laboratories that test and analzye both new and used fluids and gases.

    The paper presents in some detail the responsibilities of the various subcommittees and the harmonization efforts to work with international standards organizations.

    Some specific examples of our work are cited in terms of the events that preceded the need to standardize a procedure.
