Advanced technical ceramics - Monolithic ceramics, thermo-physical properties - Part 2: Determination of thermal diffusity by the laser flash (or heat pulse) method; German version EN 821-2:1997
The document 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 mm<(hoch)2>/s to 1000 mm<(hoch)2>/s at temperatures greater than -180 ?#,,#
