Abstract
The most important actions to ensure the correct indication of measuring instruments are:--In industrial metrology, regular calibration of the measuring instruments according to the implemented quality systems; and--In legal metrology, periodic verification or conformity testing of the instruments according to legal regulations.Both actions are strongly interrelated and are predominantly based on the same measuring procedures. Historically, however, these actions have been established with separate rules, metrological infrastructures and activities. This paper, therefore, addresses the differences, common basis and the relationship between calibration and verification. In particular, the relationships between legally prescribed error limits and uncertainty and the uncertainty contribution of verified measuring instruments are discussed.Citation
