Standard Test Method for Evaluating the Resistance to Thermal Transmission of Materials by the Guarded Heat Flow Meter Technique
- ASTM E1530 - 11(2016). Book of Standards Volume: 14.05, p.1-9, 2016 .
This test method covers a steady-state technique for the determination of the resistance to thermal transmission (thermal resistance)of materials of thicknesses less than 25?mm. For homogeneous opaque solid specimens of a representative thickness, thermal conductivity can be determined (see Note 1). This test method is useful for specimens having a thermal resistance in the range from 10 to 400?×?10-4?m 2·K·W-1, which can be obtained from materials of thermal conductivity in the approximate range from 0.1 to 30?W·m-1·K-1 over the approximate temperature range from 150 to 600?K. It can be used outside these ranges with reduced accuracy for thicker specimens and for thermal conductivity values up to 60?W·m-1·K -1.
