    Abstract - (Show below) - (Hide below)

    Describes principles and testing procedures for determining, by means of the guarded hot plate or heat flow meter methods, the thermal resistance of test specimens either in the dry state or conditioned to equilibrium with moist air, having a thermal resistance of not less than 0,1 m^2. K/W and a (hygro) thermal transmissivity or thermal conductivity up to 2,0 W/(m.K). Also support additional limits for equipment performance and test conditions.

    Scope - (Show below) - (Hide below)

    This standard specifies principles and testing procedures for determining, by means of the guarded hot plate or heat flow meter methods, the thermal resistance of test specimens either in the dry state or conditioned to equilibrium with moist air, having a thermal resistance of not less than 0,1 m2.K/W and a (hygro)thermal transmissivity or thermal conductivity up to 2,0 W/(m.K). (It is expected that the thermal resistance of most masonry specimen will be less than 0,5 m2.K/W).
