適用范圍：1.1 This part of ISO 22007 specifies a method for the determination of the thermal diffusivity of a thin soliddisc of plastics in the thickness direction by the laser flash method. This method is based upon themeasurement of the temperature rise at the rear face of the thin-disc specimen produced by a short energypulse on the front face.1.2 The method can be used for homogeneous solid plastics as well as composites having an isotropic ororthotropic structure. In general, it covers materials having a thermal diffusivity, α, in the range1 × 10
