This document specifies the principle design specifications for digital calibration certificates. These principles are the basis for all applications that will: process, transmit or receive calibration certificates according to the specifications of DIN EN ISO/IEC 17025. In order to exchange calibration certificates in a digital environment, it is essential to have a uniform and internationally accepted fundamental design. This design must be defined in a way that all information specified in the ISO 17025 standard are respected. The metrological data included in digital certificates must consist of a numerical value and a corresponding unit as a minimum. These specifications are described in deliverable 1 of the project. The overall purpose is to build the foundations for uniform digital communications based on existing metrological standards.

The development of the unified meta data format for the exchange of measurement data in ICT applications and its implementation is part of the research project EMPIR 17IND02 (title: SmartCom). This project has received funding from the EMPIR programme co-financed by the Participating States and from the European Union's Horizon 2020 research and innovation programme.
