This Standard describes a water-calorimeter method and a parallel hot wire method for determining the thermal conductivity of refractories.The hot-wire method is applicable at temperatures up to and including 1600°C and to materials having a thermal conductivity lower than 25 W/(m.K) and a thermal diffusivity lower than 10û6m2/s. Electrically conducting materials are excluded. The water-calorimeter method is designed for refractories having a conductivity of not more than 30 W/(m.K).The parallel hot-wire method is a dynamic measuring procedure based on the measurement of the temperature increase at a certain location at a specified distance from a linear heat source embedded in a test piece.This Standard is not applicable to refractories consisting predominantly of fibres.
