United States Accreditation Board (USAB) Accreditation for Inspection Bodies.

“ISO/IEC 17020:2012 – General Criteria for the Operation of Various Types of Bodies Performing Inspection” is an internationally recognized standard for the competence of the inspection bodies. Many people confuse ISO 17020 with ISO 9001, which is a generic quality management system. ISO 17020 requires evaluation of the technical competence of an inspection body.
