The advantage of accreditation initially lies in the confidence in the testing, calibration, certification and inspection results as well as in the access to international schemes of mutual recognition of calibration certificates, inspection and testing reports as well as in the compliance certificates, or in competence. International recognition of testing, certification and inspection results reduces the unwanted repetition of procedures and mitigates circumstances allowing for an easy flow of goods, services and persons. In the regulated area, accreditation represents a tool utilized by the state administration bodies for authorizing the conformity assessment bodies that operate according to relevant regulations.
