Technical Activities

The Section currently maintains the following three NEMA Standards:

  • CB 1 -- Brushes for electrical machines;
  • CG 1 -- Manufactured graphite/carbon electrodes;
  • CG 2 -- Powdered graphite.

The Section also works with the U.S. Technical Advisory Group to IEC TC 27, the Japan Carbon Association, and the European Carbon and Graphite Association with regard to influencing the development and maintenance of international standards relating to the above-listed NEMA standards.

Government Affairs

Through NEMA, the section develops industry positions on legislative and regulatory initiatives that may affect member products, markets, and customers. NEMA's work has resulted in contributions to public policy development and in promoting competitiveness, technological progress, and public safety. On the Government Affairs homepage members can search for and e-mail federal representatives to convey opinions regarding energy policy or other issues related to the electroindustry.

NEMA Government Affairs provides specific services to its members and information in the areas of Environment, Health & Safety; Energy; and International Trade & Commerce.
