Thermal conductivity measurements at room temperature
are presented as the basis for certified values of
Standard Reference Material 1453, Expanded Polystyrene
Board. The measurements have been conducted in
accordance with a randomized full factorial experimental
design with two variables, bulk density and temperature,
using the National Institute of Standards and Technology
one-meter line-heat-source guarded hot plate.
Uncertanities of the measurements, consistent with
current international guidelines, have been prepared.
The thermal conductivity measurements were conducted
over a range of bulk density of 37.4 to 45.8 kg/m3 and
mean temperature of 281 to 313 deg K. Statistical
analyses of the physical properties of the Standard
Reference Material 1453 are presented and include
variations between boards, as well as within boards.
