Metrology Symposium 2017

(27 October 2017)

The Council and the Standards and Calibration Laboratory co-organised the Metrology Symposium 2017. (Flyer)

In November 2018, the 26th General Conference on Weights and Measures (CGPM) reviewed the International System of Units (SI) of four of the seven base units namely kilogram, ampere, kelvin and mole by fixing the values of the Planck constant (h), the elementary charge (e), the Boltzmann constant (k) and the Avogadro constant (NA). Upon approval, the redefined SI would be implemented worldwide on the following World Metrology Day which is on 20 May 2019.

Obviously, this event will have major impacts on the worldwide science and metrology community. This Symposium attempted to unfold the latest development of this important event to the local testing and certification industry, as well as the parties interested in metrology. Taking this opportunity, the progress in revision of a seminal document for the metrology community – "Guide to the Expression of Uncertainty in Measurement" was also reported in the Symposium.
