A concept of interlaboratory consensus for categorical characteristics of a substance, material, or object

Interlaboratory studies are widely used for: 1) evaluation of calibration and measurement capabilities of national metrology institutes and designated institutes participating in key and supplementary comparisons; 2) estimation of proficiency (competence) of calibration and testing laboratories; and 3) development of certified reference materials. When a reference value for the measurand is unknown, the laboratory results may be used to estimate (build) a measurand consensus value applicable ...

Large-Scale Virtual Calibration of MEMS Sensors

The EU Digital Decade Policy Programme 2030 strongly depends on safe and reliable cutting-edge technologies, like Micro-Electro-Mechanical Systems (MEMS) sensors, that are widely used in large sensor networks for infrastructural, environmental, healthcare, safety, automotive, energy and industrial monitoring. Their massive production, often in the order of millions/week, requires costly and time-consuming calibration processes, resulting in a lack of metrological traceability. Indeed, current...

Development of a humid gas generator for sensors calibration in hydrogen

The urgent need to mitigate climate change and global warming to 1.5 °C requires an international effort toward decarbonization. In response, the European Green Deal aims to achieve climate neutrality with a net-zero emissions economy by 2050, highlighting the importance of renewable and low-carbon energy sources. Hydrogen is a key element to enable such a transition in the transport and energy sectors, as a zero-emission energy carrier that facilitates long-term energy storage and the decarb...
