FIELD: measurement equipment.
SUBSTANCE: method consists in heating of one of surfaces of a sample or its section to the maximum temperature which is maintained to the moment when the measured difference of temperatures on boundaries of the studied section decreases to a preset value. Then the heating power is decreased until the stage of sample cooling with the measured rate of change of temperature which does not exceed the pre-set value. The specific amount of heat, temperature increment on boundaries for two consecutive intervals of time are measured, first of interval is defined by the moments: heat supply and achievement of pre-set rate of change of temperature. Heat conductivity and a volume heat capacity are determined by formulas.
EFFECT: increase in accuracy of determination of thermophysical properties and reduction of time of measurement.
