DIN EN ISO 22007-4:2012-04

DIN EN ISO 22007-4 specifies a method for the determination of the thermal diffusivity of a thin solid disc of plastics in the thickness direction by the laser flash method. This method is based upon the measurement of the temperature rise at the rear face of the thin-disc specimen produced by a short energy pulse on the front face. The method can be used for homogeneous solid plastics as well as composites having an isotropic or orthotropic structure. The text of ISO 22007-4:2008 has been prepared by ISO/TC 61 "Plastics" (secretariat: SAC, China) and has been identically adopted as a European Standard by Technical Committee CEN/TC 249 "Plastics" (secretariat: NBN, Belgium). The responsible German committee at DIN, the German Institute for Standardization e. V., is the Plastics Standards Committee (FNK), Working Committee NA 054-01-03 AA "Physikalische, rheologische und analytische Prüfungen" ("Physical, rheological and analytical tests").
