Current, Under Review
Defines principles and criteria for conformance for determining the laboratory steady-state heat transfer properties of masonry walls in a hot box, using a heat flow meter mounted on one face of the masonry wall to be tested. Covers apparatus, measurement technique and necessary data reporting. Does not define a particular apparatus design as requirements vary, especially in size, and to a lesser extent to operating conditions.
