25、1-04 EN 410:2011 (E) 4 Introduction While this European Standard presents the formulae for the exact calculations of the spectral characteristics of glazing, it does not consider the uncertainty of the measurements necessary to determine the spectral parameters that are used in the calculations. It
26、should be noted that, for simple glazing systems where few measurements are required, the uncertainty of the results will be satisfactory if correct measurements procedures have been followed. When the glazing systems become complex and a large number of measurements are required to determine the sp
27、ectral parameters, the uncertainty is cumulative with the number of measurements and should be considered in the final results. The term interface used in this European Standard, is considered to be a surface characterized by its transmission and reflections of light intensities. That is, the intera
28、ction with light is incoherent, all phase information being lost. In the case of thin films (not described in this European Standard), interfaces are characterized by transmission and reflections of light amplitudes, i.e. the interaction with light is coherent and phase information is available. Fin
29、ally, for clarity, a coated interface can be described as having one or more thin films, but the entire stack of thin films is characterized by its resulting transmission and reflection of light intensities. In Annex B, the procedure for the calculation of spectral characteristics of laminated glass
30、 makes specific reference to coated glass. The same procedure can be adopted for filmed glass (e.g. adhesive backed polymeric film applied to glass). DIN EN 410:2011-04 EN 410:2011 (E) 5 1 Scope This European Standard specifies methods of determining the luminous and solar characteristics of glazing
31、 in buildings. These characteristic can serve as a basis for lighting, heating and cooling calculations of rooms and permit comparison between different types of glazing. This European Standard applies both to conventional glazing and to absorbing or reflecting solar-control glazing, used as vertica
32、l or horizontal glazed apertures. The appropriate formulae for single, double and triple glazing are given. This European Standard is accordingly applicable to all transparent materials except those which show significant transmission in the wavelength region 5 m to 50 m of ambient temperature radia
33、tion, such as certain plastic materials. Materials with light-scattering properties for incident radiation are dealt with as conventional transparent materials subject to certain conditions (see 5.2). Angular light and solar properties of glass in building are excluded from this standard. However, r
