National legal metrology organizations include: the Chinese Academy of Metrology, China Institute of Metrology and Inspection, China Metric System Association and the China Institute of Standardization. Specifically as follows:
1. China Academy of Metrology
Engaged in metrological scientific research, analysis, testing, technical advice, etc., to carry out sampling and testing, the development of national metrological standards and calibration devices.
2. China Institute of Metrology and Inspection
Responsible for the research and design of national metrological regulations and policies, experimental measuring instruments and technical services, the development of basic metrological standards and technical regulations, metrological standards and inspection technology transfer and promotion.
3. China metric system association
Mainly engaged in metrication, metrication laws and regulations, metrication certification, metrication authorization, metrication technology, metrication culture, metrication management, metrication network, etc., for the state and the society to provide metrication scientific and technological information and metrication technology services.
4. China National Institute of Standardization
