There are three types of reference materials used to verify numerous standard test methods: certified reference material (CRM), transfer standard (TS), and reference material (RM). A qualified reference material must be isotropic, and have reproducible consistency and stability over a wide range of temperatures. Metals ...
The aim of this study was to determine whether steady-state methods were better at measuring thermal conductivities of oven-fired clay masonry materials than transient methods, and vice versa. The Transient Plane Source (TPS) Method was tested, and when the results were compared with the other ...
