The American National Standards Institute (ANSI) is a private, non-profit organization that administers and coordinates the U.S. voluntary standardization and conformity assessment system.
The Institute oversees the development of thousands of standards that directly impact businesses in nearly every sector. Topics covered range from the largest construction equipment to the smallest nanoparticles, and from the most detailed applications to the broadest definition of a systems implementation. ANSI is also actively engaged in accrediting programs that assess conformance to standards.
The ANSI Federation is comprised of government agencies, organizations, corporations, academic and international bodies, and individuals. In total, the Institute represents the interests of more than 125,000 companies and 3.5 million professionals.
ANSI is the official U.S. representative to the International Organization for Standardization (ISO) and, via the U.S. National Committee, the International Electrotechnical Commission (IEC).
