Methods of test for dense shaped refractory products - Determination of thermal conductivity by the hot wire (parallel) method Ingestion-build-135476 specifies requirements for activities that1 scope This European Standard describes a hot wire (parallel) method for the determination of thermal conductivity of refractory products and materials. It is applicable to dense and insulating shaped products and to powdered or granular materials (see 6. 2), for thermal conductivities of less than 25" " W m. K. The limits are imposed by the thermal diffusivity of the test material and therefore by the dimensions of the test pieces; higher thermal
