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. Many NEMA standards are become American National Standards under the procedures of the American National Standards Institute. The approval of NEMA outlet box standards are is carried out under the Accredited Canvass method however the decision on how NEMA standards are approved as ANSI standards rests with the particular NEMA Section concerned.

- Publication of new NEMA OS 4 standard for air-sealed electrical outlet boxes
- Development of a training module on boxes in fire resistive construction
