Plastics. Determination of thermal conductivity and thermal diffusivity - Laser flash method1 Scope This document 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

The method is recommended for zinc contents between 0
