Refractory materials - Determination of thermal conductivity - Part 1 : Hot-wire method (cross-array)
Belongs to a series of standard and specifies a hot-wire method for the determination of the thermal conductivety of refractory products. The method is applicable at temperatures not higher than 1250 °C and to materials whose thermal conductivity is less than 1,5 W/(m.k) and whose thermal diffusivity is less than 10-6 m2/s. Subject to the limits in 1.2, the method is applicable to powdered or granular materials. It is not applicable to refractory materials consisting of or containing fibres.
