ANSI

ANSI is the abbreviation for the American National Standards Institute. It is a private non-profit organization that oversees the development of voluntary standards for products, services, processes, systems, and personnel in the United States.
ANSI accredits standards that are developed by representatives of standards developing organizations, government agencies, consumer groups, companies, and others. These standards ensure that the characteristics and performance of products are consistent, people use the same definitions and terms, and products are tested along common standards.
