29、tandard provides the means (in part) to assess the contribution that building products and services make to energy conservation and to the overall energy performance of buildings. Heat and moisture transfer calculations require design values of thermal and moisture properties for materials used in b

30、uilding applications. Design values can be derived from declared values that are based on measured data on the product concerned, which is usually the case for thermal insulation materials. Where the design conditions differ from those of the declared value, the data needs to be converted to the app

31、licable conditions. This International Standard provides the methods and data for making this conversion. For materials for which measured values are not available, design values can be obtained from tables. This International Standard provides such tabulated information based on the compilation of

32、existing data (see reference documents listed in the Bibliography). DIN EN ISO 10456:2010-05 EN ISO 10456:2007 + AC:2009 4 1 Scope This International Standard specifies methods for the determination of declared and design thermal values for thermally homogeneous building materials and products, toge

33、ther with procedures to convert values obtained under one set of conditions to those valid for another set of conditions. These procedures are valid for design ambient temperatures between 30 C and +60 C. This International Standard provides conversion coefficients for temperature and for moisture.

34、These coefficients are valid for mean temperatures between 0 C and 30 C. This International Standard also provides design data in tabular form for use in heat and moisture transfer calculations, for thermally homogeneous materials and products commonly used in building construction. 2 Normative refe

45、 or equivalent national method; heat flow meter, in accordance with ISO 8301 or equivalent national method; calibrated and guarded hot box, in accordance with ISO 8990. 4.1.2 Test conditions To avoid conversions, it is recommended that measurements be conducted under conditions corresponding to the

46、selected set of conditions given in Table 1. The mean test temperature should be chosen so that the application of the temperature coefficients does not introduce a change of more than 2 % from the measured value. The following testing conditions are required: measured thickness and density for iden

47、tification; mean test temperature; moisture content of the specimen during test; (for aged materials) age of the specimen and conditioning procedures before testing. 4.2 Tests for moisture properties Measured values of water vapour resistance factor or water vapour diffusion-equivalent air layer thi
