ASTM International Standard Practice for Thermal Conductivity of Materials Using a Thermal Capacitance (Slug) Calorimeter ASTM E2584-07

1.1 This practice describes a technique for the determination of the apparent thermal conductivity, a, of materials. It is for solid materials with apparent thermal conductivities in the approximate range 0.02 a 2 W/(mK) over the approximate temperature range between 300 K and 1100 K. Note 1 While the practice should also be applicable to determining the thermal conductivity 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. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
