Fibrous Alumina-Silica Insulation Board as a Candidate Standard Reference Material of Thermal Resistance

摘要

Measurements of apparent thermal conductivity are reported in order to provide the basis for certifying fibrous alumina-silica insulation board as a Standard Reference Material (SRM) of thermal resistance. These data encompass ranges of temperature from 93 to 746 K, densities from 207 to 308 kg/cu m3, and fill-gas pressures from roughing-pump vacuum to atmospheric pressure, in environments of both air and helium. Detailed analyses and intercomparisons of previously published data are given.
