On 20 May 2019, the World
Metrology Day (WMD) 2019, the International System of Units (SI) was revised so
that all the seven base units, namely, the second, the metre, the kilogram, the
ampere, the kelvin, the mole and the candela, were defined based on seven
defining constants related to the fundamental laws of nature. The re-definition
removes the instability imposed by the use of artefact standards and makes
these SI base units “fundamentally better”. Hence, the official theme for WMD
2019 was chosen as “The International System of Units – Fundamentally better”.
A poster designed by SCL was used globally to promote this event.
The revision of the SI enables
the base units to be realized with accuracies limited only by the physical
nature and our technical capability but not by their definitions. In recent
year many innovative primary methods have been developed or refined for the
practical realization of the base units using the law of physics. Some examples
are the X-ray-crystal-density (XRCD) method for realization of the kilogram,
the single electron transport (SET) method for realization of the ampere, the
cryogenic radiometer for realization of the candela and the use of optical
methods to realize the second. There were also numerous advances in the field
of reference material and the metrology of chemistry and biology. The Symposium
attempts to unfold to the local testing and certification industry as well as
the parties interested in metrology how the revised SI will enable us to
enhance the accuracy in measurement science and technology. Advance topics in
the latest research and development related to the primary standards in various
fields will also be discussed.
