The 14 th International Symposium on Temperature and Thermal Measurements in Industry and Science (TEMPMEKO) and the 4 th International Temperature Conference, Beijing (TEMPBEIJING) were held jointly along with the Metrology for Meteorology and Climate conference (MMC) in 2019, in the city of Chengdu in the People’s Republic of China. This joint event was hosted by the National Metrology Institute of China (NIM) and the Chinese Society for Measurements. The events attracted attendees from all over the world. The event had 190 oral presentations and 222 poster presentations across a breadth of topics. Figure 1 shows the distribution of oral presentations by topic.

“…For high-temperature calibrations, the freezing or melting plateau of metals, which are remarkably consistent, are used as temperature fixed points. [8][9][10] To facilitate this, fixed-point blackbody furnaces equipped with graphite crucibles are employed, containing various metals such as indium (In) and copper (Cu). This setup enables calibration over a wide temperature range traceable to the international temperature scale.…”

In this study, we address the challenge of calibrating radiation thermometers using blackbody furnaces that employ metal melting/freezing plateau. Here, we present a first observation results utilizing X-rays, enabling us to monitor the entire temperature cycle, from heating to cooling, during the calibration process. Through this approach, we directly observe the emergence of voids within deteriorating metal cells, which may give insights into the underlying mechanisms occurring within enclosed graphite cells.

Research on the methodology and instrument of traceable measurement of surface temperature based on an “ideal plane” model

Because the emissivity of a measured sample is difficult to determine in an in situ measurement and the emissivity of a pyrometer is different in the in situ measurement and calibration, the measurement results of the pyrometer are not traceable to a standard—The International Temperature Scale of 1990. To solve this problem, an ideal plane is proposed in this paper. The measured sample and the thermocouple are in a vacuum blackbody, and a gold-plated reflector is in contact with the measured sample. The surface can emit blackbody radiation during the measurement. The emissivity of the measured surface is always the same as that during calibration, so the uncertainty of emissivity is eliminated. In addition, the temperature of the measured sample is the same as that of the thermocouple in the vacuum blackbody; in doing so, the temperature differences between them are eliminated, and the uncertainty of the traceable measurement of the measured surface is greatly reduced. The instrument has been developed and tested. The results show that the average difference of traceable measurements in the range of 600–900 °C is 2.29 °C, while the uncertainty is 0.52 °C.
