Abstract: A new application for the transient hot-wire technique for thermal conductivity measurements has been described. It is intended to provide an accurate means of implementation of the method to the determination of the thermal conductivity of solids exemplified by a standard reference ceramic material. Measurements of the transient temperature allows an absolute determination of the thermal conductivity of the solid. The uncertainty achieved for the thermal conductivity is better than ±1%, and for the product (IC p) about ±3%. The whole measurement involves a temperature rise less than 4 K.
