标准简介：1.1 This part of ISO 22007 specifies a method for the determination of the thermal conductivity and thermal
diffusivity, and hence the specific heat capacity per unit volume, of plastics. The experimental arrangement
can be designed to match different specimen sizes. Measurements can be made in gaseous and vacuum
environments at a range of temperatures and pressures.
1.2 This method is suitable for testing homogeneous and isotropic materials, as well as anisotropic
materials with a uniaxial structure. In general, the method is suitable for materials having values of thermal
conductivity, λ, in the approximate range 0.01 W⋅m<up −1>⋅K<up −1> ＜ λ ＜ 500 W⋅m<up −1>⋅K<up −1> and values of thermal
diffusivity, α, in the range 5 × 10<up −8> m<up 2>⋅s<up −1> ≤ α ≤ 10<up −4> m<up 2>⋅s<up −1>, and for temperatures, T, in the approximate
range 50 K ＜ T ＜ 1 000 K.
1.3 The thermal-transport properties of liquids can also be determined, provided care is taken to minimize
thermal convection.
