Provides the basis for accreditation from an Accreditation Body. Since the standard focuses on competence, accreditation is simply formal recognition of a demonstration of that competence. Accreditation is performed by independent verification organizations to ensure impartiality. This is widely agreed as the most commonly used standard of accountability for use to verify laboratory competency and performance capability
