Abstract
Glavna namjera istraživanja je neovisno ostvarenje Međunarodne temperaturne ljestvice ITS-90 kroz niz temperaturnih fiksnih tocaka (trojnih tocaka, krutišta i tališta cistih metala) u podrucju od -40 °C do 660 °C, te poboljšanje prenošenja sljedivosti na sekundarne etalone temperature. Ostvarenje temperaturne ljestvice ukljucilo je definiranje eksperimentalne metode za umjeravanje etalonskih termometara primarnom metodom, određivanje matematickog modela umjeravanja i racunanja mjerne nesigurnosti za definiciju u temperaturnim fiksnim tockama i za interpolaciju između tocaka. Predloženo istraživanje poboljšalo je mjerne mogucnost Laboratorija za procesna mjerenja kao \Nacionalnog etalona temperature Republike Hrvatske, te je ostvareno kroz nekoliko znanstvenih i tehnoloških projekata koje je potpomoglo Ministarstvo znanosti i tehnologije. Rezultati neovisne realizacije ITS-90 eksperimentalno su potvrđeni kroz niz međulaboratorijskih usporedbi sa ekvivalentnima europskim nacionalnim etalonima. U podrucju prenošenja sljedivosti na sekundarne etalone ispitan je koncept višeuložne fiksne tocke, te je eksperimentalno potvrđen pozitivan utjecaj na smanjenje nesigurnosti pri usporedbenom umjeravanju termometara.
Abstract (english)
Main goal of investigation is the realization of the International Temperature Scale (ITS-90) using set of the temperature fixed points (triple points, freezing points and melting points of pure metals ) in the range from -40 °C to 660 °C, and improved dissemination of the traceability from realized scale to secondary temperature standards. Realization of the Temperature scale ITS-90 included definition of the experimental method for calibration of primary temperature standards, design of mathematical model for calibration and calculation of the uncertainty of calibration in temperature fixed points and uncertainty of interpolation between fixed points. Proposed investigation improved measurement and calibration capabilities of Laboratory for Process Measurements as Croatian National Temperature Standard, and was supported by Ministry of Science and Technology. Results of calibrations are confirmed through interlaboratory comparisons with other National Measurement Institutes. In field of dissemination of the scale on secondary standards new concept of multientrance fixed point is investigated, and was found it's particulary positive effect on reducing uncertainties in comparison calibration of thermometers.
