This part of EN 821 describes a method for the determination of thermal diffusivity of advanced monolithic technical ceramics, to an accuracy of approximately +/- 5%. It is suitable for the measurement of thermal diffusivity values in the range 0.1 mm2/s to 1000 mm2/s at temperatures greater than -180°C.
