2019 World Metrology Day

2019 WMD

Forum on International Trend of Metrology

To echo the historical changes in the International System of Units (SI), the Bureau of Standards, Metrology & Inspection (BSMI) and National Measurement Laboratory (NML) co-organized a Forum on International Trend of Metrology in Taiwan on 20 May, when the redefinition of the SI came into effect. It is also the World Metrology Day (WMD), an annual celebration of the signing of the Metre Convention in 1875. Dr. Yukinobu Miki, Vice President of International Committee of Legal Metrology (CIML) and Dr. Takashi Usuda, Secretary of the International Committee for Weights and Measures (CIPM) were invited to attend the event.

Featuring the same theme as the 2019 WMD “The International System of Units—Fundamentally Better”, the event included keynote speeches, a summit forum, and a lab tour session, gathering 160 experts from the industrial, academic and research communities.

For the keynote session, Dr. Takashi Usuda and Dr. Chia-Seng Chang, Director of the Institute of Physics at Academia Sinica, were invited to give the talks and present their views on “The Background and Impact of the Revision of International System of Units and “Trend of Modern Metrology and Quantum Physics” respectively. Six panellists shared their perspectives on the challenges and responses to the innovative application of new metrology development. The afternoon session was a tour to the new SI laboratory, where methods associated with the latest standards for four SI base units were introduced, including the Si-Sphere for mass standards, acoustic/microwave resonant chamber for temperature standards, Josephson voltage system and the quantum Hall resistance system for electrical current standards, and the isotope measurement system for mole standards.

Dr. Lian Jin-zhang, Director-General of BSMI, stated that precision measurement has a profound impact on various sectors and is closely associated with industries involved in semiconductors, energy, aerospace, and medical technology. In response to the revision of the SI, NML has been working to bring in new metrological technique to enhance the calibration and measurement capabilities which ensure the national standards with traceability and global conformity.

Dr. Lian also expressed his gratitude for the participation of local and foreign experts in metrology to the Forum. He believes that joint engagement in the SI revision will drive scientific development towards higher accuracy and precision, which will positively contribute to the growth of technology and innovation and further assist in industrial transformation and competitiveness enhancement.
