2.3 Metre Convention
15
on the arrangement of used measurement units. As of 23 March 2018, there are 59
Member States and 42 Associate Member States.
The activities carried out by the signatories of the Metre Convention have led to
the uniformity of measures on a global scale, enabling the comparison of results of
measurements performed in different places at different times and under different
conditions, which is of fundamental importance in science, technology, and the global
economy. The important tasks assigned to the Metre Convention, were as follows:
• To define international units of measurement;
• To ensure worldwide uniformity of measurement through the dissemination and
improvement of the metric system;
• To ensure equivalence of measurement standards in the signatory countries of the
Metre Convention;
• To achieve international compliance measurements, increasing mutual trust in the
reliability of measurement results.
In order to accomplish its objectives, the Convention set up three bodies:
• General Conference on Weights and Measures (CGPM; Conférence Générale des
Poids et Mesures);
• International Committee for Weights and Measures (CIPM; Comité international
des Poids et Mesures);
• International Bureau of Weights and Measures (BIPM; Bureau International des
Poids et Mesures).
The General Conference on Weights and Measures (CGPM) is made up of delegates from all Member States and is convened every four years; it approves the system
of SI units of measurement and the results of basic research in metrology. The International Committee for Weights and Measures (CIPM) consists of 18 representatives of
the CGPM and supervises the work of the BIPM, appoints the chairmen of Consultative Committees and co-operates with other international metrological organizations.
The International Bureau of Weights and Measures (BIPM) is a research institute set
up to carry out Convention tasks, acting under the direction and supervision of the
International Committee of Weights and Measures. The BIPM makes recommendations regarding the findings in the field of metrology, coordinates research units and
standards, and organizes interlaboratory comparisons (called key comparisons) for
laboratories maintaining national standards of measurement.
2.4 International Metrological Infrastructure
2.4.1 International Bureau of Weights and Measures (BIPM)
The BIPM is considered to be the world center bringing together the most eminent
experts in the field of metrology, which provides the possibility of a global coordination of metrological work at the highest level. BIPM activities primarily include
