1.1本规范涵盖了用于建筑玻璃的玻璃涂层的光学和美学质量要求。 1.2覆盖的涂层使用热解或真空（溅射）沉积方法涂覆在玻璃上，通常用于控制太阳能热增益、能量性能、舒适度和冷凝，并提高建筑的美观。 1.3本规范仅涉及与涂层相关的瑕疵。它不解决玻璃瑕疵、应用的陶瓷熔块和有机薄膜。 1.4尺寸值以英寸-磅单位表示，并视为本规范的标准单位。括号中给出的公制单位仅供参考。

1.1 This specification covers the optical and aesthetic quality requirements for coatings applied to glass for use in building glazing. 1.2 The coatings covered are applied to the glass using either pyrolytic or vacuum (sputtering) deposition methods and are typically applied to control solar heat gain, energy performance, comfort level, and condensation and enhance the aesthetic of the building. 1.3 This specification addresses blemishes related to the coating only. It does not address glass blemishes, applied ceramic frits, and organic films. 1.4 Dimensional values are stated in inch-pound units and are to be regarded as the standard units for this specification. The metric units given in parentheses are for information only.
