Mathematical models have been developed for the calculation of measurement errors of the coefficients of the heat conductivity and thermal diffusivity of thermal insulating materials. A technique for selection of the following optimal parameters was created, based on models: duration of the heat pulse and the chief structural dimensions of the measuring device. Optimal conditions for applying the algorithm for processing the experimental data were also defined.
