ASTM E2584 – Standard Practice forThermal Conductivity of Materials Using a Thermal Capacitance(Slug) Calorimeter
1.1 This practice describes a technique for the determination of the apparent thermal conductivity, λa, and thermal diffusivity, αa, of materials. It is for solid materials with apparent thermal conductivities in the approximate range 0.02 < λa < 20 W/(m·K) over the approximate temperature range between 300 K and 1100 K, if used stainless steel 304 slag calorimeter and K thermocouples, and up to 1600 K, if used Alumina slag calorimeter and PtRh thermocouples.
Note 1: While the practice should also be applicable to determining the thermal conductivity and thermal diffusivity of non-reactive materials, it has been found specifically useful in testing fire resistive materials that are both reactive and undergo significant dimensional changes during a high temperature exposure.
