Standard Test Methods for Thermal Conductivity and Thermal Diffusivity Using a Double-Spiral Configuration of the Transient Plane Source Method

Importancia y uso:

5.1 Thermal transport properties are required for such purposes as design applications, estimation of operating temperature, process and quality control, or ranking products in relative order of their thermal transport properties.

5.2 The methods determine true bulk thermal properties of a wide range of materials over a broad temperature range from a single transient recording.

5.3 Thermal properties are determined as “at temperature” rather than “mean temperature” measurements, such that the results are not averaged over the large thermal gradient inherent in, for example, some steady-state techniques.

5.4 The methods and DS configuration of the transient plane source method are particularly advantageous because of ease of specimen preparation, flexible specimen size, rapidity of measurements, and ease of handling.
