Withdrawn
A Withdrawn Standard is one, which is removed from sale, and its unique number can no longer be used. The Standard can be withdrawn and not replaced, or it can be withdrawn and replaced by a Standard with a different number.
Plastics - Determination of thermal conductivity and thermal diffusivity - Part 2: Transient plane heat source (hot disc) method (ISO 22007-2:2008)

ISO 22007-2:2008 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.
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 Wm-1K-1 < λ < 500 Wm-1K-1 and values of thermal diffusivity, α, in the range 5 x 10-8 m2s-1 ≤ α ≤ 10-4 m2s-1, and for temperatures, T, in the approximate range 50 K < T < 1 000 K.
The thermal-transport properties of liquids can also be determined, provided care is taken to minimize thermal convection.
