Who is ANSI?

ANSI stands for the

American National Standards Institute.

ANSI was founded in 1918 as a non-profit organization who accredits companies or groups as competent in undertaking specific tasks. ANSI’s guidelines are recognized worldwide as best practices.

American National Standard Institute compliance is voluntary, however, those companies who wish to conform to these standards more readily find a home among the global marketplace: they meet a standard of unification.
