The main components of international recognition of national standards, calibration, and measurement capabilities

International recognition of measurement results improves the development of international trade, science, and technology. It helps to reduce technical barriers in international trade, improve product quality, and increase confidence in calibration and testing laboratories. The recognition of national standards is critical for ensuring global metrological consistency between countries and ensuring international confidence in carried out measurements. National standards are subject to comparison with the standards of other countries. National Metrology Institutes (NMIs) and Designated Institutes (DIs) are responsible for establishing and maintaining national standards of units of measurement and ensuring their compliance with international standards. The results of comparisons of national standards, review, and adoption of calibration and measurement capabilities (CMC) of NMIs and DIs are published in the special Key Comparison Database (KCDB) of the International Bureau of Weights and Measures (BIPM). An analysis of the current state of implementation of the Mutual Recognition Agreement (MRA) of the International Committee for Weights and Measures (CIPM) — CIPM MRA was carried out. The basis of this analysis is the results of key and supplementary comparisons of national standards, structured by regional metrological organizations (RMOs), types of measurements, as well as CMC of NMIs and DIs both by RMOs and types of measurements and by countries. The place of Ukraine in the implementation of the CIRM MRA Agreement is shown.
