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.
- The LVDE Section actively works with US, Canadian and Mexican bodies on regional standards through CANENA.
- Influence international standards - LVDE committees develop industry input used in the development of US positions on IEC (International Electrotechnical Commission) and ISO (International Organization for Standardization) standards. The LVDE Section also administratively supports selected US National Committee Technical Advisory Groups (TAGS) to the IEC, and US TAGS for ISO automation activities.
- Arc Fault Circuit Interrupters AFCIs prevent arc faults becoming electrical fires and are required by the NEC. The LVDE Section promotes their use though the website
