The Bureau of Standards, Metrology and Inspection (BSMI) under the Ministry of Economic Affairs held the 2026 World Metrology Day Symposium on 19 May 2026. The symposium explored three major themes-smart manufacturing and AI, net-zero transition, and the new energy industry, highlighting that metrology is not only essential to the stable operation of industries across all sectors, but also serves as a critical foundation for national policymaking and fostering public trust.
World Metrology Day is celebrated globally on May 20 each year to commemorate the signing of the Metre Convention in 1875, which laid the foundation for global measurement consistency, and to reflect on how metrology can help address future challenges. As a member of the General Conference on Weights and Measures (CGPM), the BSMI organized a symposium under the 2026 theme, "Metrology: Building Trust in Policy Making." It aimed to foster greater public awareness and understanding of the importance of metrology through the sharing and discussion of real-world case studies.
The BSMI noted that the metrology system is fundamental to ensuring fair market transactions and maintaining public confidence in government enforcement. Currently, 22 categories of legal measuring instruments have been designated under regulation. Any legal measuring instrument subject to mandatory verification must complete verification before importation or release from the factory to ensure the accuracy and consistency of measurement results, while also protecting consumer rights and maintaining fair trade practices.
In addition, BSMI has also aligned its efforts with the government's energy transition and industrial upgrading policies. It is actively advancing hydrogen metrology technologies, developing standards for hydrogen refueling stations, and improving the green electricity trading framework, with the aim of gradually establishing a reliable standards and metrology foundation for emerging energy industries. At the same time, by integrating metrology with AI technologies, the BSMI is developing services for sensor calibration, automated equipment calibrations, and geometric measurement of machine tools, helping the smart machinery industry improve measurement data quality, enhance process stability, and strengthen international competitiveness.
The symposium featured distinguished speakers from industry and academia. Mr. Cheng Tzu-yen, General Manager of Chroma ATE Inc., delivered a presentation entitled "The Development of Smart Manufacturing and the Role of Metrology in the AI Wave," exploring how smart manufacturing integrates AI applications with metrology to strengthen quality assurance and build trust across global supply chains. Mr. Lee Chien-ming, Senior Consultant at the Taiwan Research Institute, presented on "Metrology Supporting High-Integrity Net-Zero Transition," explaining the pivotal role of metrology in carbon management and net-zero governance. In addition, Mr. Huang Yi-hsieh, Senior Energy Consultant at Taiwan Cement Corporation Group Holdings, shared insights on "Metrology Challenges and Policy Implementation in the New Energy Supply Chain," highlighting the importance of establishing standardized metrology systems to support the implementation of new energy policies.
As the world moves toward digital governance, sustainable development, and energy transition, policymaking increasingly depends on a precise and reliable metrological foundation. The BSMI will endeavor to align with the nation's development vision and strategies by leveraging internationally harmonized metrology standards and the solid foundation of the National Measurement Laboratory. Guided by the principles of "precise metrology, sustainable development, and intelligent innovation," BSMI is committed to enhancing the credibility and impact of public policy and serving as a strong backbone for the sustainable development of Taiwan's industrial economy.
