Beyond their evaluations, measurement uncertainties raise many questions about their use in the context of the declaration of conformity of “products and services”. If different approaches have been developed over the past years, including the “capability approach”, 2012 has seen the JCGM document #106 being published. This paper just published, was taken as an international standard ISO/IEC Guide 98-4 by ISO in the very same year and has just been taken (2013) in the collection of French standards (NF ISO/IEC Guide 98-4). This approach is singularly different from traditional approaches in that it introduces Bayesian concepts in the world of Metrology that was hitherto relatively impermeable to it. With this new approach, metrologists discover that measure is not a science of discovery, but a science of confirmation (or denial) of an “a priori”.
