The American National Standards Institute (ANSI) is a private non-profit organization that coordinates the development and use of voluntary consensus standards in the United States and the conformity assessment system in the U.S.  

Internationally, ANSI promotes the use of U.S. standards, advocates U.S. policy and technical positions in international and regional standards organizations, and encourages the adoption of international standards as national standards where they meet the needs of the user community.

In these capacities, ANSI oversees the creation, promulgation and use of thousands of norms and guidelines that directly impact businesses in nearly every sector: from acoustical devices to construction equipment, from dairy and livestock production to energy distribution, and many more. ANSI is also actively engaged in accreditation - assessing the competence of organizations determining conformance to standards.
