Thermal conductivity measurements from an international
interlaboratory study between the United States and
Canada are presented for two materials, glass-fiber
board and fibrous alumina silica. The measurements were
determined using guarded hot plate apparatus at the
National Institute of Standards and Technology and at
the National Research Council Canada. The nominal bulk
densities and thicknesses for the specimens of
glass-fiber board and fibrous alumina silica were 160
kg/m3 and 25.1 mm, and 290 kg/m3 and 25.2 mm,
respectively. Measurements of thermal conductivity were
conducted over a temperature range of 273 K to 340 K.
Statistical regression analyses of the data are
