Abstract
The development of calibration procedures, as well as the certification of readily available reference materials (RMs) and the improvement of their metrological characteristics, are topical issues for thermal analysis methods. In the course of the work, the necessity of conducting a study in order to expand the range of CRMs for temperature and enthalpy of phase transitions is substantiated. The substantiation of the choice of the measurement procedure and starting materials is given. The conditions for conducting experiments are described in detail, and the choice of these conditions is justified. The developed CRMs passed the metrological examination and were included in the Register of approved types of reference materials FIF EUM as a set of certified reference materials for temperature and specific enthalpy of phase transitions (set SOTSF-2) GSO 11890–2022/GSO 11896–2022. The practical significance of the obtained results is as follows: certified reference materials allow expanding the possibility of establishing and monitoring the stability of the calibration characteristics of thermal analysis installations and measuring instruments; certification of measurement procedures (methods) and accuracy control of the measurement results of the phase transition temperature of metals, metal salts, metal oxides, and polymeric materials, organic and inorganic substances.
