Im intelligenten Messsystem, z.B. zur Messung elektrischer Energie im Haushalt, werden Zählerstände und andere Daten im Smart Meter Gateway (SMGW) gespeichert (s. Abb. 1). Diese Daten müssen vertrauenswürdig verfügbar gemacht und dargestellt werden können.

Die Transparenz- und Display-Software (TRuDI) wird von der Initiative Bundesdisplay [1] entwickelt und regelmäßig erweitert. Sie dient der...

Uncertainty evaluation in the presence of measurement data is a common task in metrology. The documents of the GUM serve as the de-facto standard for uncertainty evaluation in metrology. Supplement 1 to the GUM recommends a so-called Type A uncertainty evaluation, which is implicitly based on a non-informative Bayesian inference. This observation and the fact that Type A uncertainty evaluation can...

Harmonization is essential in the context of pathogen measurements. Different laboratories and studies must provide consistent and reliable measurement results. Standardization is the ideal case in which quantification of pathogens is traceable to SI units. The aim of the workshop was to explore the major challenges and different metrological approaches, including future perspectives. Validation...

Figure 1: Distributed measurement systems and their treatment in existing PTB requirements. (K: Client).

On 9 September 2024, PTB’s Working Group 8.51 held a hybrid software workshop with over 100 manufacturer representatives. The core objective of the workshop was to contribute to improving the software testing process through a common understanding of the technical and organisational requirements, thereby reducing the effort involved, for example, in document creation and testing for all...

ISO Standards give recommendations to solve technical but also medical questions. They improve quality, safety and efficiency of products and services.  The currently completed EMPIR project BioStand-2 addressed detection of pathogens. The contributions focused on ISO TS 5798. This standard deals with genetic detection of SARS-CoV-2 viruses. It describes the complete workflow from sampling, via...
