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,s W/mK 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. These materials may therefore require pre-treatment; the nature and extent of such pre-treatment and the period for which the test piece is held at the measurement temperature, as a preliminary to canying out the test, are details that are outside the scope of this Part of EN 993 and should be agreed between the parties concemed. NOTE 2 : In general it is difficult to make measurements on anisotropic materials. The use of this method for such materials should also be agreed between the parties concerned.
