Brief Introduction



Founded in 1955, National Institute of Metrology (NIM) is the national metrology institute (NMI) of China, subordinate to General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ), China. It is the nation’s highest technical authority in the field of metrology as well as a non-profit R&D institution for social benefit, which is responsible for providing metrology services of the highest accuracy and reliability to customers. Since founding, NIM has been aiming at world competence in front edge of metrological science, while providing accurate, reliable and traceable measurements to support the nation’s economic construction, social sustainability and technical development. Our main tasks are as follows:

•Research, establish, maintain and improve national primary standards & national standards;

•Research and develop national certified reference materials (CRMs);

•Research, realize, maintain and disseminate the legal time in China;

•Participate in international comparisons to ensure traceability and international equivalence of national standards;

•Disseminate values to its clients through verification and calibration services, ensure all unit values are traceable and reliable within the nation;

•Carry out fundamental and frontier research in metrological science, study measurement theory and technique; develop value disseminating and tracing methods, etc.    


Currently, NIM has 798 staff members, 652 of which are scientific or technical workers, including 2 academicians of Chinese Academy of Engineering, 74 senior research fellows, 262 associate research fellows. Among them, 129 are awarded with PhD and 185 with Master’s degree, forming 48.2% of the scientific and technical group.


NIM maintains 130 national primary standards, 277 national standards and provides 1137 types of CRMs, including 412 first class CRMs and 725 second class CRMs. NIM has 1166 Calibration and Measurement Capabilities (CMCs) released in BIPM KCDB. This ranks number 5 of all BIPM member countries. In 2012, about 150,000 sets of instruments were verified and calibrated at NIM.


Since founding, 77 projects held by NIM have won national awards for scientific and technical findings, including 5 first-prize State Scientific and Technological Progress Awards, 72 National Awards for Natural Science, second and third-prize of State Scientific and Technological Progress Awards and National Awards for Scientific and Technological Inventions. Besides, 362 province-and-minister-level awards for scientific and technical findings have been honored.


In 2012, NIM continues to reinforce its bilateral cooperation with foreign NMIs, including NIST, PTB, NPL, NMIA and KRISS, in frontier research and key technology development of metrology field. 20 top scientists and specialists of NIM went to advanced NMIs of foreign countries for at least 3-month exchange study or cooperation.


In the national Twelfth Five-Year Plan period (2011-2015), NIM will adhere to the national principles of developing science and technology, and take serving national economical and social development as our core mission. The three priority tasks of NIM are: to improve fundamental research, to support national strategy and to upgrade measurement and service capabilities. The great emphasis will be laid on developing new fields of metrology which will support emerging strategic industries of China. NIM will aim at optimizing organizational structure, facilities construction, scientific and technological collaboration, human resource development, and the adoption of new mechanism that encourages innovation. NIM is aiming to become a world-class NMI which can produce so much progress and so many top scientists as to contribute to the nation’s task of building an affluent society with common prosperity.
