An experimental design for the thermal characterization
of Standard Reference Material 145Oc, Fibrous Glass
Board, is presented. The measurements have been
conducted following a randomized full factorial
experimental design with two variables, bulk density and
temperature, using the National Institute of Standards
and Technology's one-meter guarded hot plate apparatus.
Certified values of thermal resistance have been
established for a temperature range from 280 K to 340 K
and bulk density from 150 kg/m3 to 165 kg/m3". Standard
uncertainties for the measurements, consistent with
current international guidelines, are included.
