- Scope
- This standard specifies the basic principles, calculation formulas, specimen preparation, measurement devices, measurement systems, operating systems and data processing for transient measurement of thermal conductivity and thermal diffusion coefficient of solid materials using a planar heat source and pulse heating with constant heat flow intensity. Contents such as the key points of measurement operations and the expression of measurement results. This standard is suitable for measuring the thermal conductivity and thermal diffusion coefficient of solid sheets such as thermal insulation materials and thermal conductive materials in a humid state or a bone-dry state, near room temperature. The test range is 0.01 W•m-1&# 8226;K-1 ＜λ＜500 W•m-1•K-1 and 5×10-8 m2•s-1 ≤ α ≤ 10-4 m2•s-1.
