This is a method for measuring accurate thermal conductivity without performing absolute measurements of heat quantity, by simultaneously measuring a reference sample with known thermal conductivity.
This measurement method, also known as the steady-state comparison method, is referred to as the protective heat flow meter method in ASTM E1530. In this method, a reference sample with a known thermal conductivity is measured simultaneously, allowing for the accurate measurement of thermal conductivity without the need for absolute heat flow measurements. A heater and a reference calorimeter are in close contact to create a steady state with a temperature difference of approximately 30K between the top and bottom of the test specimen. The thermal conductivity is then determined from the temperature difference at both ends of the test specimen and the output of the reference calorimeter.
