Thermal Conductivity by Guarded Heat Flow Meter (Scan)
Test ID
T-108
Description
A sample measuring 2" in diameter is placed between the upper and lower plates of a guarded heat flow meter. A thin layer of conductive grease is applied to the top and bottom of the sample and it is clamped in place. The upper and lower plates are controlled at different temperatures, thus inducing heat flow through the sample. A heated guard surrounding the sample reduces the lateral heat flow. From the measure of heat flow, thermal conductivity is calculated. Test is conducted over a range of temperatures.
