标准摘要
[中文适用范围]： 给出了用于确定具有平坦和平行表面的多层玻璃的U值（热透射率）的测量方法。 结构化表面可以被认为是平坦的。 [外文原描述]： Gives a measuring method used to determine the U value (thermal transmittance) of multiple glazing with flat and parallel surfaces. Structured surfaces may be considered to be flat.
英文名称Glass in building — Determination of steady-state U values (thermal transmittance) of multiple glazing — Heat flow meter method
