Abstract: | A method of combined determination of thermophysical characteristics (TPC) of heat-insulating materials that is based on solving the inverse heat-conduction problem is discussed. The influence of the parameters of the calculation algorithm and the uncertainty in specifying the parameters of the measuring device on the TPC measurement error is analyzed. It is shown that the measurement error considerably exceeds the scatter of the results of repeated measurements of the same sample without disassembling the measuring device.
