Abstract
Two national metrology laboratories (NMI) have conducted an international interlaboratory comparison on thermal conductivity on two thermal insulation reference materials. The Laboratoire national de métrologie et d'Essais (LNE) from France and the National Institute of Standards and Technology (NIST) of the United States present measurements obtained by the guarded hot plate method. The study involved two materials, expanded polystyrene and fibrous glass board. The expanded polystyrene was provided by the LNE which is issued as a transfer specimen; the fibrous glass board provided by NIST was issued as Standard Reference Material (SRM) 1450c. For each reference material, the study was based on four independent measurements at a mean temperature of 297.15 K and two additional mean temperatures of 283.15 K and 308.15 K.Proceedings Title
