Abstract: The paper reports on the measurement of thermophysical properties (thermal conductivity and diffusivity) of PMMA (polymethylmethacrylate). The theory of the dynamic plane heat source method and the experimental apparatus are discussed. Both the sensitivity coefficients and difference analysis are used for searching the time interval in which the measured data can be evaluated. Besides, the influence of the heater and heat losses from the lateral sides of the sample and also the influence of the noise are studied. The estimated measurement uncertainties are 3.6% for thermal conductivity and 2.7% for thermal diffusivity.
