FIELD: thermal-physical measurement technology.
SUBSTANCE: temperature of surface of the sample and environment temperature are measured at specific points by means of two temperature detectors. Correction factor is found from received results. Then surface of the sample is put under influence of motionless point heat source. Excess temperatures of surface to be heated are measured by two temperature detectors at specific points at preset moment of time. While keeping on heating the sample, the time moment is measured when temperature of temperature detector being located at the longest distance from spot of heating increases by preset value. Coefficients of thermal diffusivity and thermal conductivity are found from measured parameters.
EFFECT: increased precision of measurement; simplified procedure of measurement.
