Technical Activities

Standards play a vital part in the design, production, and distribution of products destined for both national and international com­merce. Sound technical standards benefit the user, as well as the manufacturer, by improving safety, bringing about economies in product, eliminating misunderstandings between manufacturer and purchaser, and assisting the pur­chaser in selecting and obtaining the proper product for his particular need.

NEMA devotes much of its time, effort, and resources to voluntary standardization activities. NEMA standards are offered and recommended to become American National Standards under the procedures of the American National Standards Institute, usually under the canvass method. This decision rests with the particular subdivision or subdivisions concerned. NEMA standards are also often submitted for consideration as IEC standards components or references. It is the intent of the association to continue its support of these, and many more, activities as the best method to continue providing sound and safe electrical products for the use of all.
