Infrastructure for Digital Calibration Certificates

Digital Calibration Certificates (DCCs) will soon replace Paper Calibration Certificates (PCCs). As electronic files they can be communicated instantly and securely to the customer and are machine readable. However, DCCs require a digital security and software infrastructure to fulfil the current ‘analogue’ processes of authentication and validation that deliver a fully traceable calibration chain to primary standards. Additionally, software and knowledge representation systems will need to be put in place to support the use of DCCs both for the metrology community and for industry. We present in this work an initial analysis of the requirements of this infrastructure for DCCs in order to support Industry 4.0, the Internet of Things (IoT) and future digital metrology.
