标准范围

ISO 9050:2003规定了测定建筑物玻璃中太阳辐射的光和能量透射率的方法。这些特征数据可作为房间光照、供暖和通风计算的基础，并允许对不同类型的玻璃进行比较。ISO 9050:2003既适用于传统的嵌装玻璃单元，也适用于吸收或反射太阳能的控制嵌装玻璃，用作玻璃孔。给出了单层、双层和三层玻璃的适用公式。此外，还建立了由多个部件组成的单元的通用计算程序。ISO 9050:2003适用于所有透明材料。一个例外是，对于在环境温度辐射波长范围（5微米至50微米）内表现出显著透射率的材料，如某些塑料板，二次传热系数和总太阳能系数的处理。

ISO 9050:2003 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.ISO 9050:2003 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.ISO 9050:2003 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 microns to 50 microns), such as certain plastic sheets.
