Abstract: Advancing digitalisation does also affect the field of calibration. In view of this development and responding to the needs of industry, the digital calibration certificate (DCC) has been developed. The DCC is an XSD file (XML Schema Definition) that serves as a kind of template for digital calibration certificates for all measurands in XML format (Extensible Markup Language). Its implementation therefore requires further, subject-related specifications. To examine potential applications for the mass calibration of weights and weight sets and to determine the related specifications, the DKD Technical Committee Mass and Weighing Instrumentshas set up a group of experts who have created the present document. This document describes the contents of the digital calibration certificate for mass, volume and density calibrations of weights and weight sets. The focus here is on the flexible information in the DCC. The mandatory information, such as details of the calibration laboratory, customer or calibration date, is described in the Documentation on the DCC scheme, https://dccwiki.ptb.de/en/home. The application of the specifications described here to similar calibration items, such as mass standards or density standards, is possible in many cases without any problems. The present document refers to version 3.2.1 of the DCC schema. For implementation, it is recommended to refer to the latest version of the schema. This version is completely downward compatible and allows, among other things, improved indication of references. Given the continuous changes in the field of digital certificates, this report can only reflect the current state of discussions – something to be taken into account in any kind of evaluation or referencing. These changes may refer to changes in the schema file or to higher-level specifications such as coordinated refType attributes. The validity of the remaining regulations remains unaffected.
The expert report is accompanied by three DCC examples.
