本欧洲标准规定了用作建筑围护结构的幕墙套件的要求，以提供耐候性、使用安全性、能源经济性和保温性，并提供了相关性能的试验/评估/计算方法和符合性标准。本标准涵盖的幕墙套件应满足其自身的完整性和机械稳定性，但不影响主建筑结构的承载力或稳定性，并且可以独立于其进行更换。本标准适用于垂直位置至垂直方向±15°范围内的幕墙套件。任何倾斜部分都应包含在幕墙套件中。本标准适用于所有幕墙套件，包括固定件。本标准规定的幕墙用作建筑围护结构的一部分。本欧洲标准不包括:-“专利玻璃”（上釉倾斜屋顶）套件；-屋顶玻璃结构；-外墙由预制混凝土板制成，作为墙的一部分（见EN 14992）。注1:幕墙套件中可使用预制混凝土板作为填充板。注2:本标准不包括结构密封玻璃填充物的耐久性。

This European Standard specifies requirements of curtain walling kit intended to be used as a building envelope to provide weather resistance, safety in use and energy economy and heat retention and provides test/assessments/calculation methods and compliance criteria of the related performances. The curtain walling kit covered by this standard should fulfil its own integrity and mechanical stability but does not contribute to the load bearing or stability of the main building structure, and could be replaced independently of it. This standard applies to curtain walling kit ranging from a vertical position to ± 15° from the vertical. Any sloping parts should be contained within the curtain walling kit. This standard is applicable to the whole of the curtain walling kits, including the fixings. Curtain walling according to this standard is intended to be used as part of the building envelope. This European Standard does not include: — “Patent glazing” (glazed sloping roofs) kits; — Roof glazing constructions; — Façades made of precast concrete panels as part of the wall (see EN 14992). NOTE 1 Precast concrete panels may be used in curtain walling kits as infill panels. NOTE 2 Durability of structural sealed glazing infills is not covered by this standard.
