Abstract
The main goal of this study is to operationalize the emission, exchange and use of digital calibration certificates, through structured information and the specification of a system of information. The purpose of digital calibration certificates, is not only the transformation of a physical format to a digital one, but mainly the application of the real digitalization concept, i.e., the use of digital technologies to change a business model and supply new opportunities with added value. Besides the easiness in the exchange of calibration results, the future development of a system to exchange digital calibration certificates will allow customers to receive and analyze certificates faster, reducing execution times and costs associated to the metrological confirmation process, as well as to avoid human error and their consequences. The application of a system adapted to calibration certificates, and the implementation and testing at a National Measurement Institute as IPQ, based on XML, with examples from different areas will be presented. This study will then result in the creation of national working group in Portugal for the digitalization of calibration certificates to a broader market, with the first trial cases implemented in these two laboratories, INEGI-LAC and IPQ-LNM.
Highlights
In this digital era and Industry 4.0 environment, the results of calibration are still linked to printed documents and manual transcription which difficult the connection to information systems and industrial automation
What is the purpose of having equipment with internet connection if the results of its calibration kept in a paper format? How can a laboratory demonstrate traceability through digital media? With the purpose of maintaining competitiveness and avoiding laboratories to be stuck to communications based on paper and transcription, it is urgent the adaptation of testing and calibration laboratories to a new approach, adapting to the new reality of Industry 4.0. This will enable the use of technological advances as reported in some applications, at least partially, e.g., EMPIR project Met4FoF [1] and the German VDI initiative [2]

Summary
In this digital era and Industry 4.0 environment, the results of calibration are still linked to printed documents and manual transcription which difficult the connection to information systems and industrial automation. With the purpose of maintaining competitiveness and avoiding laboratories to be stuck to communications based on paper and transcription, it is urgent the adaptation of testing and calibration laboratories to a new approach, adapting to the new reality of Industry 4.0. This will enable the use of technological advances as reported in some applications, at least partially, e.g., EMPIR project Met4FoF [1] and the German VDI initiative [2]. One common decision rule is based on the comparison between manufacturer specifications (sometimes multiplied by a safety factor) and the sum of error (absolute value) and expanded uncertainty, and that example will be illustrated in this study
