This document will outline the "as-is" state of the existing European and international quality infrastructure for calibration. State-of-the-art cryptographic methods are presented and applications of these methods for securing and transmitting digital calibration certificates are discussed. Both, chances and risks of the digital calibration certificate are outlined.
This is the second Newsletter of the SmartCom project, published in March 2020.
The Basic DCC Concept385 KB
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 .
D-SI in Short - Digital brochure on establishing the use of units in digitalised communication643 KB
This brochure specifies principles for establishing the use of units in a digitalised communication of machine-readable data. These principles are the basis for all applications that transfer or require measurement data according to the specifications of the Système International d’Unités (SI). Fundamental principles for a harmonised, unambiguous, easy-to-understand and safe digital communication of metrological data are specified for real quantities and quantities related to constants. The principles consider a broad scope of requirements from a metrological and information and communications technology (ICT) point of view.
SmartCom Digital System of Units (D-SI) Guide for the use of the metadata-format used in metrology for the easy-to-use, safe, harmonised and unambiguous digital transfer of metrological data942 KB
This guide specifies principles for determining the use of units in digitised communication of machine-readable data. These principles form the basis for all applications that transmit or require measurement data according to the specifications of the Système International d'Unités (SI). Basic principles for harmonised, clear, easy to understand and secure digital communication of metrological data are defined for real, complex, vector and constant quantities. The metadata model described is essential for the exchange of metrological information in all fields of Information and Communication Technologies (ICT). In terms of content, the model takes into account essential international metrology guidelines and standards. For the first time, in conjunction with the globally established SI, measures are defined which are essential for an easy, secure, harmonised and unambiguous exchange of metrological data. The handling of non-SI units and the requirements for conversion between SI and non-SI quantities are taken into account. In addition, a classification for the suitability of metrological data for interoperability and machine readability is made (medal system). The classification results from the use of SI units as defined in the 9th edition of BIPM's SI brochure.
