Plastics. Determination of thermal conductivity and thermal diffusivity - Temperature wave analysis method Ingestion-build-73935 leading to a standard methodology1 Scope This part of ISO 22007 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, , in the range 1,0 108 m2s1 < < 1,0 104 m2s1. Measurements can be
