To ensure that high standards of quality and reliability also apply in a digitalized world, PTB is helping to develop a digital quality infrastructure at the German, European and global levels.

This includes the development of internationally accepted data formats that enable digital traceability to the International System of Units (SI). With this aim in mind, the International Committee for Weights and Measures (CIPM) invited leading organizations to a workshop in 2021. Here, over 600 attendees discussed the issues surrounding measurement units in metrological traceable data and the application of FAIR principles (findable, accessible, interoperable and reusable) to make this data understandable for both humans and machines. The aim is to soon achieve a joint declaration from international quality infrastructure organizations and a resolution of the 102 member states of the Metre Convention.

The challenges associated with the establishment of digital processes and certificates in legal metrology were dealt with by representatives of numerous international organizations at a workshop hosted by the International Organization of Legal Metrology (OIML). At this meeting, PTB presented the European Metrology Cloud, a digital platform developed by PTB that seeks to integrate the harmonized EU-wide procedures for conformity assessment and market surveillance into a single overarching system and to simplify access to digital certificates.
