Methods of test for dense shaped refractory products. Part 15: Determination of thermal conductivity by the hot-wire (parallel) method
This part of EN 993 specifies 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 7.2), for thermal conductivities of less than 25 W/m.K. The limits are imposed by the dimensions of the test pieces and higher thermal conductivities can be measured if larger pieces are used. Electrically conducting materials cannot be measured.
