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.

Market Economics

Through NEMA, member companies are able to develop and implement tailored, industry-specific market and statistical programs that benefit participating companies. Reports may include:

  • Product orders and sales
  • Market forecasting
  • Shipments by trading areas
  • Channels of distribution
  • Financial and operating ratios
  • Wages and benefits
  • Foreign trade

The association also conducts economic analyses on the impact of legislation and regulations on member products, and monitors and reports on key industry market indicators. All programs comply with NEMA statistical confidentiality policies. For more information, please see Business & Economy.

Membership

Membership in NEMA is open to any firm actively engaged in the manufacture in North America of a product within the NEMA scope and for sale in the open market. Membership of foreign firms is subject to product section policies and NEMA Board of Governors approval.

NEMA operates on a fee-for-service basis. Each product section establishes its projects and activities and approves an annual operating budget.
