EN 1279系列-建筑用玻璃标准

《EN1279-1“建筑用玻璃-绝缘玻璃装置-第1部分：概要、系统描述、替换规则、公差和外观质量》的内容描述了绝缘玻璃装置的定义，适用的规则、它们的光学和视觉质量标准及尺寸公差，及对已有系统适用的替代规范。此标准规范的出台，使绝缘玻璃装置满足使用者的需要，并通过在外观、节能、降噪和安全参数等方面统一标准而确保标准的稳定性。

其次，《EN1279-5“建筑用玻璃-绝缘玻璃装置-第5部分：产品标准》确立了建筑用绝缘玻璃装置的产品标准。该标准是由欧洲委员会和欧洲自由贸易协会（EFTA）授权CEN编写。如果EN 1279-5可以在欧洲联盟官方期刊(OJEU.)中根据（EU）第305/2011号条例被引用，它就很可能成为功能性声明书(DoP)和欧标认证的基础，也就是支撑EU305/2011 条例的协调标准。EN1279-5对绝缘玻璃装置性能标准做了规定，包括抗火性、耐火性、防弹性和防爆性，以及防噪和防热方面的性能。

最后，EN1279-2，EN1279-3，EN1279-4涉及以下方面的检测方法与具体要求，包括（1）防潮（2）气体泄漏率和气体浓度公差（3）绝缘玻璃装置的边缘密封和插入的安装物的物理属性。

EN1279系列是由CEN技术委员会129制定的，其技术秘书处由比利时标准化机构NBN管辖。

TheEN 1279 series was developed by CEN/TC129 and published on 25 July 2018. The standards included cover the requirements for insulating glass units. Insulating glass units offer thermal and sound insulation, and therefore they are widely used in a lot of commercial and residential building: their main use consists of installations in windows, doors, curtain walling, and bonded glazing for doors, windows and curtain walling, roofs and partitions.

EN 1279-1 ‘Glass in Building - Insulating glass units - Part 1: Generalities, system description, rules for substitution, tolerances and visual quality’ provides definitions for insulating glass units and covers the rules for system descriptions, their optical and visual quality and dimensional tolerances, and sets the substitution rules based on an existing system description. The achievement of this standard’s requirements indicates that insulating glass units fulfil the needs for intended use and ensures, by means of the evaluation of conformity, that visual, energetic, acoustic, and safety parameters do not change significantly over time.
