CALIBRATION OR VERIFICATION OF MEASURING INSTRUMENTS – WHAT NEEDS FOR INDUSTRY?

P. Barbier

Abstract

For a long time the terms calibration and verification and verification have often been used as synonyms. Sometimes the difference of meaning is connected with the application in legal metrology or in industry. Today the international Vocabulary of Basic and General Terms in Metrology (second edition – 1993) doesn’t speak about verification but other standards make its definition clear. In industry what is to be done in the context of Quality assurance implementation? From our point view the user has to choose between ‘calibration” and ”verification” in order to demonstrate the traceability to national or international standards. The purpose of this paper is to propose a clear scheme of application in industry taking in consideration a third possibility: the application of Statistical Process Control Techniques in place of – or together with – calibration or verification.
