This part of ISO22007 specifies a temperature wave analysis method for the determination of the thermal diffusivity of thin films and plates of plastics in the through-thickness direction. The method can be used on plastics in either the solid or molten state, and having either an isotropic or an orthotropic structure. The method covers values of the thermal diffusivity, α, in the range 1,0×10−8 m2·s−1
