Forum on International Trend of Metrology

To echo the historical changes in the International System of Units (SI), ITRI and the Bureau of Standards, Metrology & Inspection (BSMI) co-organized a forum on International Trend of Metrology in Hsinchu, Taiwan on May 20th, when the redefinition of the SI came into effect and the World Metrology Day (WMD), an annual celebration of the signing of the Metre Convention, took place.

The International System of Units—Fundamentally Better

Featuring the same theme as the 2019 WMD, “The International System of Units—Fundamentally Better”, this year’s event included keynote speeches, a summit forum, and a lab tour session, gathering experts from the industrial, academic and research communities. Dr. Takashi Usuda, Secretary of the International Committee for Weights and Measures (CIPM), and Dr. Chia-Seng Chang, Director of the Institute of Physics at Academia Sinica, were invited to be the keynote speakers 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 new 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.

ITRI Chairman Dr. Chih-Kung Lee 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, ITRI has been working to bring in new metrological techniques to enhance the calibration and measurement capabilities of the National Measurement Laboratory. This practice can ensure the traceability and global conformity of the national standards, and in turn, will secure the leading position of Taiwan’s high-tech and precision industries.

Dr. Lee also expressed his gratitude for the participation in the forum of local and foreign experts in metrology. 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.
