标准摘要
[中文适用范围]： ISO 22007 的这一部分规定了一种温度波分析方法，用于测定塑料薄膜和板材在厚度方向上的热扩散率。该方法可用于固态或熔融态的塑料，也可用于具有各向同性或正交各向异性结构的塑料。该方法涵盖的热扩散率 α 值在 1.0 × 10 m⋅s ＜ α ＜ 1.0 × 10 m⋅s 范围内。测量可以在空气或其他气氛（例如惰性气体）、大气压或其他减压或加压条件下，或在真空下、在各种温度下进行。 [外文原描述]： 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 m 2 s -1 < α < 1,0 x 10 -4 m 2 s -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.
