A Cryogenic Heat-Flow-Meter Apparatus

Source

A cryogenic thermal-conductivity heat-flow-meter apparatus (cryogenic heat meter), a modification of the apparatus described in a previous ASTM publication, is described. This apparatus enables a rapid determination of thermal conductivity of felt, powder, and block materials to be made at cryogenic temperatures and at atmospheric pressure. The apparatus is particularly suitable for screening a large number of specimens, for obtaining product development information, and for quality control testing. The correlation among results obtained with the cryogenic heat meter and the Wilkes calorimeter and a National Bureau of Standards' cryogenic calorimeter is excellent. Correlation of cryogenic heat-meter results with those obtained at higher temperatures on a heat-flow-meter apparatus and a guarded-hot-plate apparatus is good. A range of temperatures can be applied to the test specimen. Therefore, use conditions can be simulated, if desired.
