Abstract:

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.
