適用范圍：This International Standard provides the method of calculation of the thermal resistance and thermaltransmittance of building components and building elements, excluding doors, windows and other glazed units,curtain walling, components which involve heat transfer to the ground, and components through which air isdesigned to permeate.The calculation method is based on the appropriate design thermal conductivities or design thermalresistances of the materials and products for the application concerned.The method applies to components and elements consisting of thermally homogeneous layers (which caninclude air layers).This International Standard also provides an approximate method that can be used for elements containinginhomogeneous layers, including the effect of metal fasteners, by means of a correction term given inAnnex D. Other cases where insulation is bridged by metal are outside the scope of this InternationalStandard.
