Current Structure and Activities of ASTM Committee D09

Over the last 14 years, the span of my direct involvement with ASTM, many changes have occurred not only in the membership and goals of Committee D09, but also in ASTM itself. This paper will highlight the various Subcommittees within Committee D09 and some of the activities that have been completed over the past several years. In addition, the current topics of discussion within these Subcommittees will be pointed out. Committee D09 has a working relationship with other ASTM committees and standards organizations and some of these activities will be covered as well. D09 membership is made up of approximately 160 individuals representing users, manufacturers, and general interest groups. Members may participate in as many subcommittees as they desire. In D09 the 160 members are responsible for 194 standards. The scope of D09 is to develop test methods, practices, terminology, specifications, and promote knowledge and research relating to solid and solidifying fluid electrical insulating materials. The principal materials included are grades designed primarily for electrical insulating or dielectric purposes of the following: • Varnishes and resins • Reinforced, laminated, filled and unfilled themoplastic and thermosetting plastics • Metal-clad dielectrics • Glass and Mica • Embedment resins, compounds, and waxes
