Standard Reference Materials: SRM 1450d, Fibrous-Glass Board, for Thermal Conductivity from 280 K to 340 K.

摘要

Thermal conductivity measurements at and near room temperature are presented as the basis for certified values of thermal conductivity for SRM 1450d, Fibrous Glass Board. The measurements have been conducted in accordance with a randomized full factorial experimental design with two variables, bulk density and temperature, using the NIST 1016 mm line-heat-source guarded-hot-plate apparatus. The thermal conductivity of the SRM specimens was measured over a range of bulk densities from 114 kgDTm-3 to 124 kgDTm-3 and mean temperatures from 280 K to 340 K. Uncertainties of the measurements, consistent in format with current international guidelines, have been prepared. Statistical analyses of the physical properties from the SRM are presented and include variations between boards, as well as within board.
