The ANSI-ASQ National Accreditation Board is the U.S. accreditation body for management systems certification (under the ANAB brand) and an accreditation body for laboratories, inspection bodies, reference material producers, and proficiency testing providers (under the ACLASS brand).

ANAB ensures that the CBs it accredits are competent and comply with the international requirements. Like its counterparts in other countries, ANAB oversees the competency of those it accredits through a rigorous system of evaluation and accreditation.

BSI Management Systems, one of the world’s leading certification bodies, and the ANSI-ASQ National Accreditation Board (ANAB), the national accreditation body of the USA, have signed an agreement under which ANAB will provide accreditation services to BSI around the world. It is proposed that BSI should be accredited for all major products, for all scopes, in all countries in which BSI has operations.
