Methods of test for dense shaped refractory products. Part 14: Determination of thermal conductivity by the hot-wire (cross-array) method
This part of EN 993 specifies a hot-wire (cross-array) 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 7.3), for thermal conductivities of less than 1,5 W/m.K.Electrically conducting materials cannot be measured. Note 1: The thermal conductivity of bonded bricks may be affected by the appreciable amount of water that is retained after hardening or setting and is released on firing.
