Apparatus for determining thermal conductivity of materials

摘要

A method and apparatus for measuring thermal conductivity of materials is provided. A test specimen is placed intermediate a hot plate and a cold plate, and a heat flow sensing means is placed intermediate the material to form two portions of the test specimen. A guarded hot plate measurement of the heat flow to the hot plate enables calibration of the sensitivity of the specimens and the heat flow sensing means. The apparatus is then calibrated for measurement of other specimens of like physical properties.
