Abstract
The German expert group “AK-Thermophysik” of the Association of Thermal Analysis (GEFTA, Gesellschaft für Thermische Analyse e.V.) further initiated a round robin test for thermal conductivity in the year 2012. With this additional use of the expanded glass granulate material, more experience with transient methods and thermal conductivity values in the extended temperature range could be obtained. The thermal conductivity of expanded glass granulates was determined from â170 °C to 530 °C with different methods and apparatuses. Within this temperature range the thermal conductivity increases from about 0.030 W mâ1 Kâ1 to 0.160 W mâ1 Kâ1. The comparison with the reference curve of the VDI/Keymark indicates very good compliance within 4% for most cases.
