PTB-News 2.2018 – Conventional calibration certificates could soon become history. To furnish proof that a measuring instrument has been calibrated and of how this has been done, metrology institutes throughout the world could, in the near future, use digital calibration certificates (DCCs) rather than their analog version. Especially the fact that they are machine-readable speaks in favour of DCCs for production and quality monitoring processes in which digitalization is becoming ever more important. The ultimate goal consists in developing universal DCC exchange formats valid for all areas of metrology.
