Resumen:
This docuemnt specifies the hot-wire method (cross-array method) and resistance thermometer method for the determination of thermal conductivity of non-carbonacious, dielectric refractory products and materials. The hot-wire method is applicable to refractories with a thermal conductivity less than 1,5 W/m x K and the resistance thermometer method is applicable to refractories with a thermal conductivity less than 15 W/m x K.
