Project management summary: The aim of the project is to develop an accredited method for measuring thermal conductivities at high temperatures, temperatures above 450 °C, using the Guard Hot Plate (GHP) method. The results of the work will be available for the development of a Czech standard for measuring thermal conductivities using the Guard Hot Plate method. Currently, there is only a preliminary standard from 2015 (CEN/TS 15548-1), which now contains unrealistic requirements. In practice, this work should bring, in addition to an accredited laboratory, a unification of the measurement of thermal conductivities using a protected heating plate in the Czech Republic. Correct measurement of thermal conductivities ensures the correct design of insulation layers and thus reduces the energy consumption of equipment (e.g. high temperature furnaces). It also increases the credibility of the relationship between customer and vendor - for example, there are now different thermal conductivity data for identical insulation material, these data vary depending on the equipment on which the insulation material was measured.
