This standard is one of a series of standards for the evaluation of the thermal performance of building materials and products. 1 Scope This standard gives design data in tabular form for heat and moisture transfer calculations, for thermall
18、y homogeneous materials and products commonly used in building construction. It also gives data to enable the calculation and conversion of design thermal values for various environmental conditions. 2 Normative references This European Standard incorporates by dated or undated reference, provisions

27、:2000 Design thermal values can be derived from declared thermal values by applying the conversion procedures in EN IS0 10456. This is normally the case for thermal insulation materials. The method of determination of the declared thermal value for an insulation material is specified in product stan
28、dards. Design thermal values for masonry materials are usually derived from the thermal conductivity in the dry state using EN IS0 10456. NOTE The thermal conductivity in the dry state for masonry materials is given in prEN 1745:1994, Masonry and masonry products - Methods for determining design the
29、rmal val ues . 4.2 Tabulated design thermal values Table 1 gives design thermal values for materials in general in building applications. When appropriate, linear interpolation may be used. For insulation materials and masonry materials, Table 2 gives the moisture content of materials and products i
30、n equilibrium with air at 23 OC and relative humidities of 50 % and 80 %, and moisture conversion coefficients taken from EN IS0 10456. Table 2 also gives the water vapour resistance factor and specific heat capacity for these materials. Table 3 gives the water vapour diffusion-equivalent air layer
