The kelvin redefinition

NMIJ has started dissemination of thermodynamic temperature above 960 oC by relative primary radiometric thermometry method.

Relative primary radiometric thermometry• Interpolation or extrapolation from three or more

fixed points.• Thermodynamic temperatures are assigned for

high-temperature metal-carbon eutectic fixed points.

Mise en pratique for the definition of the kelvin in the SI (MeP-K-19)

• The new definition is no longer be linked to the triple point of water.• No uncertainty propagation from TPW.• Primary thermometry will increasingly supplant the defined

temperature scales for realization and dissemination of the unit.• At high temperatures, absolute or relative primary thermometry can

already give similar or superior uncertainties to ITS-90.

For educational institutions and studentsExhibited at Science Plaza at the National Science Education Convention and introduced the new definition.(Held in Gifu Prefecture in 2018 and Kochi Prefecture in 2019)

There were many teachers who intently listened how to explain the redefinition to their students.For chemistry teachers, it was effective to explain by using the X-ray crystal density method, and for physics teachers, using the watt balance method.

Neck strap commemorating the historic redefinition of the SI base units

This year, NMIJ has produced a neck strap for the anniversary of theMeasurement Act of Japan, with the aim of promoting the SI in responseto the resent redefinition of the SI base units.The day of 1st November, when the act was revised and implemented in1993, was enacted as the anniversary in Japan.

Design concept: Feel the revised SI familiarDesigned with the SI logo, the seven SI base units, the seven physical constants defining the units, and the words that express the philosophy of the metric system. "À tous les temps, à tous les peuples" (For all times, for all peoples)

• Mission and Strategy of NMIJ• To continue establishment and dissemination of national metrology

standard.

• More direct commitment to the industry, not only by disseminating metrology standards but also by providing solutions to their activities.

• Expanding Scope of National Metrology System• Employing the revised SI.

• Promote the redefinition in various ways: from "knowing" phase to "using" phase.

• Analyzing economic impact by national metrology system is continuously needed.
