Refractory materials. Determination of thermal conductivity - Hot-wire methods (cross-array and resistance thermometer)1 Scope This part of ISO 8894 describes the hot wire methods (cross array and resistance thermometer) for the determination of the thermal conductivity of non carbonaceous, dielectric refractory products and materials. This methods are applicable to dense and insulating refractories (shaped products, refractory castables, plastic refractories, ramming mixes, powdered or granular materials) with thermal conductivity values less than 1,5 W mK (cross
