FIELD: nondestructive teat. SUBSTANCE: method consists in adiabatic effect of heat source-on surface of semi-infinite (in thermal relation) body under test, measurement of heat flow density, preliminary determination of thermocouple error depending on temperature, recording of thermograms at indicated points of surface, taking the temperature values off thermograms at preset moment of time, and determination of thermal conductivity with due regard for errors introduced by thermocouples into temperature measurement results. EFFECT: higher accuracy of measurements. 2 tbl
