Thermal conductivity is an inherent or absolute property of Thermal resistance varies with thickness. the material. Test Methods – ASTM D Thermal Impedance A property of a particular assembly measured by the ratio of the temperature difference between two surfaces to the steady-state heat flow through them. Factors affecting thermal impedance include: Area: Increasing the area of thermal contact decreases thermal impedance. in. diameter stack (ref. in.) – - psi, hour per layer Thickness: Increasing the insulator thickness increases thermal impedance. Pressure: Increasing mounting pressure under ideal conditions decreases thermal impedance. Time: Thermal impedance decreases over time. Measurement: Thermal impedance is affected by the method of temperature measurement.
