Abstract: The ability of leading thermal conductivity measurement techniques to be applied to the thermal measurement of thermally insulated materials was investigated. Researchers required that the equipment be able to operate between temperatures of 250 and 800°C. The equipment studied included the Hot Disk Transient Plane Source, the laser flash technique, the guarded heat flow meter, the transient hot wire instrument, and the guarded hot plate apparatus. Variables considered by the investigators included price, sample size, thermal conductivity measurement range, and temperature range. The team concluded that none of the techniques studied had the ideal combination of characteristics to test thermally insulated materials.
