The purpose of this paper is to present a laser flash technique with fast infrared detection for the measurement of the normal diffusivity of thin samples. In a first part, the apparatus designed for such a measurement is described. Then, experimental results performed within the framework of the Diamond Round Robin 2 tests are presented and difficulties in connection with their good conductivity and low thickness are pointed out.
