ISO22007-2 i.e. Transient plane heat source method (TPS), enhanced by the hot wire method from. <br>Temperature probe with a self-heating function is loaded in the sample, by applying a constant heating power the probe test, its temperature rises, and the probe then the probe itself and spaced from the ball surface temperature rise over time relationships are measured, thermal conductivity and thermal diffusivity of the sample are obtained simultaneously by fitting the mathematical model.

ISO22007-2 is the transient plane heat source method (TPS), which is improved by the hotline method.<br>The temperature probe with self-heating function is loaded into the sample, and a constant heating power is applied to the probe during the test to increase its temperature, and then the relationship between the probe itself and the temperature on the spherical surface at a certain distance from the probe is measured over time, and the thermal conductivity and thermal diffusion coefficient of the sample are fitted simultaneously through a mathematical model.
