标准简介：1.1 This part of ISO 22007 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.
1.2 The method can be used for homogeneous solid plastics as well as composites having an isotropic or
orthotropic structure. In general, it covers materials having a thermal diffusivity, α, in the range
1 × 10<up −7> m<up 2>⋅s<up −1> ＜ α ＜ 1 × 10<up −4> m<up 2>⋅s<up −1>. Measurements can be carried out in gaseous and vacuum
environments over a temperature range from − 100 °C to + 400 °C.
