本欧洲标准适用于由正常重量制成的预制墙体或结构密实的轻质混凝土。也可以使用纤维增强混凝土（由欧洲标准覆盖的钢，聚合物或其他纤维）。这些墙壁元件可能具有外墙功能（见3.11）或不具有面向功能（见3.12）或不具有这些功能的组合。 外墙功能可以是: - 保温（见3.11.1）; - 隔音（见3.11.2）; - 湿度控制（见3.11.3）; 或这些的组合。 它们可以是平坦的，加强的或预应力的。他们可能是负载的。 这些包括: - 实心墙; - 复合墙; - 三明治墙; - 减轻墙壁; - 包裹。 壁元件也可以作为柱或梁进行工作

This European Standard applies to prefabricated walls, made of normal weight or lightweight concrete with dense structure. Also fibre reinforced concrete (steel, polymer or other fibres covered by European standards) may be used. These wall elements may have external wall functions (see 3.11) or not, have facing functions (see 3.12) or not or have a combination of these functions. External wall functions could be: - thermal insulation (see 3.11.1); - sound insulation (see 3.11.2); - hygrometric control (see 3.11.3); or a combination of these. They may be plain, reinforced or prestressed. They may be loadbearing or not. These include: - solid walls; - composite walls; - sandwich walls; - lightened walls; - claddings. The wall element may also work as a column or beam.
