This report presents results of thermal conductivity tests of basalt core and calibrated reference materials. Thermal conductivity was measured on basalt specimens which were previously tested by another laboratory so that laboratory procedures and results from different laboratories could be directly compared. Basalt specimens of varying thickness were tested in order to evaluate the testing equipment sensitivity to specimen geometry. Specimens were prepared by sequentially sawing and grinding the 32-mm-thick Rockwell-supplied basalt specimens to 15, 8 and 5 mm in order to minimize effects due to variations in mineralogy and grain size. Test results indicated that measured thermal conductivity was related to specimen size and test temperature. Primary reference materials with thermal conductivity in the range of 1 to 7 W/m-K are not available from the National Bureau of Standards. 2 refs.
