Accreditation, as defined by Webster, is to give trust or confidence, to vouch for, to recommend, or to furnish with credentials, as an envoy or ambassador. According to ISO 17011:2004, accreditation is a third-party attestation related to a conformity assessment body, conveying formal demonstration of its competence to carry out specific assessment tasks.

EU Certification Limited's accreditation of Conformity Assessment Bodies (CABs) and Further Training/Educational Institutions provides formal demonstration to carry out specific certification, inspection, registration verification/validation, assessment, testing, calibration, and training/educational activities. This independent assessment and recognition may permit accredited organizations' tests, examination reports, and certificates to be recognized as equivalent to those of organizations in other countries.
