The primary responsibility of the NMI in each country is to ensure the uniformity
of units and the required accuracy of measurements. Thus, the mission of NMIs is
to provide uniformity in the country through the development and maintenance of
state measurement standards and the transfer of units of measurement to the market.
Each NMI occupies the highest position in the national metrology of economically
developed countries: it conducts research activities, performs measurements, consults
and acts as a center of expertise metrology. It is a key partner for ensuring the linkage
of the national system of measurement with the worldwide system.
2.4.3 Regional Metrological Infrastructure
The activities of metrological organizations on an international scale and their cooperation with national counterparts have been described above. Another level of the
infrastructure involves the actively functioning regional organizations that work with
both within the Metre Convention and with national institutes. The regional organizations of metrology (e.g., the Regional Metrology Organization; RMO) coordinates
activities in the field of metrology on regional level, to disseminate knowledge, organize joint R&D programs, as well as to ensure consistency of measurement of the
subordinate NMIs, by organizing key, complementary and bilateral comparisons and
through reviewing measurement capabilities declared by the NMIs. Regional organizations are also involved in providing support to developing countries in building
and maintaining metrological infrastructure (Fig. 2.2).
