The conference is intended for discussion of the state of fundamental, applied, and scientifi c-industrial aspects of the development and application of means of measurement of temperature and thermophysical quantities. The conference was organized into fi ve sections which examined the following topics: the reproduction and transfer of temperature scales; radiation thermometry; applied problems of thermometry, sensors, secondary transducers, materials, and designs; temperature measurement in nuclear power, metrology, and practice; and, the measurement of thermophysical quantities and metrological support.More than 100 talks were given. The participants in the conference included experts from Russia and the COOMET countries (Belarus, Kazakhstan, Kyrgyzstan, Moldova, Uzbekistan, and Ukraine), as well from the leading metrological institutes of Europe, NPL (UK),
PTB (Germany), LNE (France), VSL (Netherlands), SMU (Slovakia), and CMI (Czech Republic).An exhibition of instrumentation for measurement of temperature and thermophysical quantities was held as part of the conference, as well as round tables with participants from Rosstandart, the scientifi c metrological centers of Russia, and managers from the major manufacturers of metrological equipment and instrumentation for measuring thermophysical quantities.Work on improving the national primary standard for the unit of the coeffi cient of linear thermal expansion for solids in order to extend the temperature range from 1800 to 3000 K is described. The composition and metrological characteristics of the standard are discussed, as well as methods for measuring the elongation of test samples and an improved system for transfer of the unit from the standard to working means of measurement. Keywords: standard, coeffi cient of linear thermal expansion, dilatometer, optical methods for measurement of elongation.The thermal expansion of materials is a general property of most condensed media, including solids. Measurements of thermal expansion are needed in almost all modern branches of engineering and technology (from the space shuttles to low-energy power generation and steam heating valves) employing parts that must fi t precisely at different temperatures.
