ISO 9050建筑玻璃的测定—标准名称
ISO 9050 Glass in building — Determination of light transmittance, solar direct transmittance, total solar energy transmittance, ultraviolet transmittance and related glazing factors
ISO 9050建筑玻璃 可见光透射比、太阳光直接透射比、太阳能总透射比、紫外线透射比及有关窗玻璃参数的测定
ISO 9050建筑玻璃的测定—适用范围
This International Standard specifies methods of determining light and energy transmittance of solar radiation for glazing in buildings. These characteristic data can serve as a basis for light, heating and ventilation calculations of rooms and can permit comparison between different types of glazing. This International Standard is applicable both to conventional glazing units and to absorbing or reflecting solar-control glazing, used as glazed apertures. The appropriate formulae for single, double and triple glazing are given. Furthermore, the general calculation procedures for units consisting of more than components are established. This International Standard is applicable to all transparent materials. One exception is the treatment of the secondary heat transfer factor and the total solar energy factor for those materials that show significant transmittance in the wavelength region of ambient temperature radiation (5 μm to 50 μm), such as certain plastic sheets. NOTE For multiple glazing including elements with light-scattering properties, the more detailed procedures of ISO 15099 can be used. For daylighting calculations, procedures can be found in reference [1].
