Customer requirement or appropriate calibration method? Which is more important?

Abstract

For accreditation of calibration laboratories, the standard reference is ISO/IEC 17025, which specifies the general requirements for competence, impartiality and consistent operation of laboratories. When analyzing various scopes of accreditation in different accreditation bodies, there was a significant variation in the Calibration and Measurement Capabilities (CMC) declaration for the same type of equipment. This article presents a critical analysis of factors that may have generated this variation. And consider the need to prioritize the adequacy of calibration methods to metrological characteristics of the equipment, in order to have less variation in the presentation of accreditation scopes.
