ISO 22007-3:20 08规定了一种温度波分析方法，用于测定塑料薄膜和板在整个厚度方向上的热扩散率。该方法可用于固体或熔融状态的塑料，并且具有各向同性或正交各向异性结构。 该方法涵盖1.0 x 10-8 m2s-1<α<1.0 x 10-4 m2s-1范围内的热扩散率α值。 测量可以在空气中或在另一种气氛(例如惰性气体)下、在大气压下或在其他降低或升高的压力下、或在真空下、在各种温度下进行。

ISO 22007-3:2008 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 x 10^-8 m²s^-1 < α < 1,0 x 10^-4 m²s^-1. Measurements can be performed either in air or in another atmosphere, e.g. an inert gas, at atmospheric pressure or at other, reduced or elevated, pressures, or under a vacuum, at a variety of temperatures.
