Possibility of using thermography at determination of heat conduction coefficient proceedings

The paper presents the possibilities of using thermography in measurement of thermal conductivity of prefabricated insulating sandwich panels and pipe/in/pipe assemblies according to EN and ISO standards. From data presented it can be seen that thermography could be successfully used in measurements of outer surface temperatures of the samples as well as thermocouples or other standard sensors. Thermography gives not only values of temperature on certain point, but also average surface temperature or average line temperature and some additional information of sample structure. Using thermography as additional tool in such measurements more useful information can be obtained in comparison with classical methods.
