JIS R 3106:2019规定了使用分光光度计测定可见光的透射率/反射率、太阳辐射的透射率/反射率/吸收率以及嵌装玻璃在环境温度下的热辐射发射率的方法。此外,本标准规定了当玻璃窗用作建筑开口时,计算总太阳能透射率的方法。这些特征数据可作为房间和can的光照、加热/冷却和通风计算的基础
允许对不同类型的玻璃进行比较。
JIS R 3106:2019 specifies methods of determining the transmittance/reflectance of visible light and the transmittance/reflectance/absorptance of solar radiation as well as the emissivity of thermal radiation at ambient temperature for glazing 1), using a spectrophotometer. Also, this Standard specifies the method to calculate the total solar energy transmittance when glazing is used as building apertures. These characteristic data can serve as a basis for light, heating/cooling and ventilation calculations of rooms and can
permit comparison between different types of glazing.
