A new method of simultaneous determination of thermal conductivity, thermal diffusivity and heat capacity using a plane-shaped heat source is investigated. The principle of this method is based on the transient temperature rise of an infimite solid by a plane heat source. Conditions and accuracy of measurements by the above principle are determined analytically. Experimental results with apparatus based upon the above conditions, using a nichrome foil heater of thickness 0.03mm and a 60×60×30mm PVC plastics sample, were satisfactory. An accuracy of 5% could be attained. The apparatus for this measuring method is simpler than that of O. Krischer or of W. Knappe.
