Modern components of activities and models of national metrological institutes

Economies and societies are constantly changing and developing, so national metrological systems also need changes and adaptation to modern conditions. National Metrological Institutes (NMI), as one of the main elements of the national metrological infrastructure, are responsible for the development and maintenance of national standards, conducting scientific research in the field of metrology. There are significant risks due to the lack of an effective metrology infrastructure at the national level. The article analyzes the main modern components of NMI activities and offers options for models of NMI functioning depending on the existing metrological infrastructure, taking into account various risks of the operation of such infrastructure.
