* Calculation of thermal conductivity from Laser Flash Diffusivity Measurement requires the additional following material properties: heat capacity (Cp), density, and coefficient of thermal expansion.
** Traditional Transient Plane Source requires iterative testing to obtain the correct experiemental parameters in terms of power flux, test time, and sizing of sensor necessary to obtain accurate results.
*** Minimum sample size depends on material's thermal diffusivity and probe radius.
