Test Method: SATRA TM146

Thermal conductivity

March 2020


This method is intended to determine the thermal properties of a material. The method is applicable to any material in sheet form.


A heater providing a constant source of heat is placed between two identical metal cylinders which are mounted such that their axes are in a vertical plane. The test specimen is placed on the top surface of the upper cylinder and a third identical metal cylinder is placed on top of the test specimen so that all the cylinders and the test specimen are concentrically aligned. The heat source is switched on and the temperatures of the three blocks are allowed to reach a steady state. The thermal conductivity of the test specimen is determined from the steady state temperatures of the three blocks, the exposed surface areas of the blocks and test specimen and the thickness of the test specimen.
