本欧洲标准草案规定了确定玻璃,涂层玻璃和其他在远红外线不透明的玻璃组件的表面的室温下的辐射率的程序。根据B.1至B.5的确定U值和玻璃窗的总太阳能透光率,考虑到在283K的标准温度下从表面辐射的热传递是必要的
This draft European Standard specifies a procedure for determining the emissivity at room temperature of the surfaces of glass, coated glass and other glazing components not transparent in the far infrared. The emissivity is necessary for taking into account heat transfer by radiation from surfaces at the standard temperature of 283 K in the determination of the U value and of the total solar transmittance of glazing according to B.1 to B.5.
