Preliminary E-infrastructure for Digital Calibration Certificate

Abstract

Calibration certificate is an important reference point for metrological measurement traceability. In connection with the approval of the latest revision of SI and the dissemination of a new reference base based on quantum standards, the issue of digitalization of calibration certificates becomes especially urgent. The possibilities of electronic and even more digital calibration certificates (hereinafter DCC) significantly improve the traceability of measurements in comparison with the traditional paper certificate. The form and content of DCC, however, are still not clearly determined and require deep study. Our work is aimed at presenting and summarizing the available results in this field, and formulating the critical questions on the creation of DCC that arise during the work on its implementation. Based on the analysis performed and our own experience in the implementation of the electronic calibration certificate (ECC) we presented a preliminary scheme for the implementation of DCC in our organization. We also touch upon related issues, namely digital signature and e-infrastructure of National Scientific Centre “Institute of Metrology” (NSC IM).
