本文件涵盖垂直安装的手动或电动可操作织物窗帘组件，具有向下关闭操作。窗帘系统不同于（与）门系统，因为其非刚性封闭元件通常由薄壁材料制成，例如编织物或针织物和箔。这些闭合元件不能通过其弯曲刚度来承受垂直于其表面的重要荷载。换句话说，幕墙系统与门系统是分开的，因为它们只能通过平面上的拉应力将拉力传递到其表面。推力不是在平面上传导到表面的。本文件规定了扩展根据EN 1634-1百叶窗试验方法进行的试验结果应用的方法。在完成从第4条中确定的一项或多项适当测试后，扩展应用程序可涵盖以下全部或部分非详尽的示例列表:-非绝缘（E）、辐射（EW）或绝缘（EI1或EI2）分类；-卷取机构；-墙\/天花板固定件；-建筑五金项目；-装饰饰面；-膨胀、通风或隔音密封；-替代支撑结构。

This document covers vertically mounted types of manual or powered, operable fabric curtain assemblies with downward closing operation. Curtain systems are different from (are separated from) door systems due to their not rigid closure element typically made of thin walled materials as for instance woven or knitted fabrics and foils. These closure elements are not able to carry significant loads normal to their surface by their bending stiffness. In other words: curtain systems are separated from door systems because they can only conduct pulling forces by tensile stress in plane to their surface. Pushing forces are not conducted in plane to their surface. This document establishes the methodology for extending the application of test results obtained from test(s) conducted in accordance with the EN 1634-1 test method for shutters. Subject to the completion of the appropriate test or tests selected from those identified in Clause 4, the extended application may cover all or some of the following non-exhaustive list of examples: - uninsulated (E), radiation (EW) or insulated (EI1 or EI2) classifications; - coiling mechanisms; - wall/ceiling fixed elements; - items of building hardware; - decorative finishes; - intumescent, draught or acoustic seals; - alternative supporting construction(s).
