ISO
The International Organization for Standardization (ISO) is a worldwide federation of national standards bodies from more than 145 countries, one from each country. ISO is a non-governmental organization established in 1947 and based in Geneva, Switzerland. Its mission is to promote the development of standardization and related activities in the world with a view to facilitating the international exchange of goods and services, and to developing cooperation in the spheres of intellectual, scientific, technological and economic activity. ISO's work results in international agreements which are published as International Standards and other types of ISO documents.

ANSI is the sole U.S. representative and dues-paying member of the International Organization for Standardization (ISO), and as a founding member of the ISO, ANSI plays an active role in its governance.

IEC
The International Electrotechnical Commission (IEC) is the leading global organization that prepares and publishes international standards for all electrical, electronic and related technologies. These serve as a basis for national standardization and as references when drafting international tenders and contracts.

The U.S. National Committee of the IEC (USNC/IEC) serves as the focal point for U.S. parties who are interested in the development, promulgation and use of globally-relevant standards for the electotechnical industry. The USNC/IEC is a totally integrated committee of ANSI, which provides administrative support to the USNC and its participants.
