The American National Standards Institute (ANSI) serves as the administrator and coordinator of the U.S. private sector voluntary standardization system. ANSI oversees the development and use of voluntary consensus standards in the United States and represents U.S. stakeholders' needs and views in standardization forums globally. With thousands of international norms and guidelines, ANSI's impact spans various sectors, from acoustics to energy distribution. The ANSI National Accreditation Board (ANAB) accredits programs assessing conformance to standards, including well-known cross-sector programs like ISO 9000 and ISO/IEC 17025. Through its facilitation and coordination of voluntary standards and conformity assessment, ANSI ensures quality and consistency in products and services.
