Authorized metrology centres

Verification of specified measuring instruments is used to detect whether the accuracy of a particular gauge, i.e., the specified gauge, complies with the required metrological properties. The authorized metrology centre issues a certificate of verification, confirming that the gauge meets the requirements of the relevant standard or regulation. The aim is to ensure safety and accuracy for billing and other purposes.
