标准摘要
[中文适用范围]： 规定了用于确定具有平坦和平行表面的多层玻璃（包括铸造和压花玻璃）的热透射系数（U 值）的测量方法。 适用于外层玻璃不能透过远红外辐射的多层玻璃，普通窗玻璃就是这种情况。 内部元件可以是远红外透明的。 [外文原描述]： Specifies a measuring method used to determine the coefficient of thermal transmittance, the U-value, of multiple glazing with flat and parallel surfaces, including cast and figured rolled glass. Applies to multiple glazing with outer panes which are not transparent to far-infrared radiation, which is the case for normal window glass. Internal elements may be far-infrared transparent.
英文名称Glass in building — Determination of steady-state U values (thermal transmittance) of multiple glazing — Guarded hot plate method
