Abstract: Hot Disk Thermal Constants Analysers are designed to test three-dimensional samples with sizes at least as large as the sensor itself. However, this study examines the possibility of using hot disk methods to test the thermal conductivity of thin solid samples when they are thermally insulated. To accomplish this, the 200 data points that are collected by hot disk TPS methods should be collected while the sample is heated for only 5 seconds, which is a shorter amount of time than a larger, three-dimensional sample would typically be monitored.
