The contact resistance is minimized by applying a pneumatic load to the test stack, and by using a thermally conductive interface compound. The contact resistance is kept small by applying a reproducible, pneumatic load to the test stack, and with the use of thermal axtm pastes. The lower polished surface is part of a calibrated heat flux transducer. The thickness of the specimen is obtained using a suitable gauge.
