BS EN 15269-11:2018涵盖了垂直安装的手动或电动可操作织物窗帘 具有向下关闭操作的组件。窗帘系统不同于（从中分离） 门系统由于其非刚性封闭元件，通常由薄壁材料制成，例如 例如机织物或针织物和箔。这些闭合元件不能承载重要的 通过弯曲刚度垂直于其表面的载荷。换句话说:窗帘系统是分开的 因为它们只能通过平面上的拉应力将拉力传递给它们的 表面推力不会在平面上传导到表面。交叉引用:EN 13501-2EN 1993-1-2EN 1363-1EN 13501-2EN 15269-1EN 1634-1EN 1993-1-2EN 15269-1EN 1634-1EN 1363-1ISO 13943EN ISO 13943EN 16035EN 15254-4EN 16034EN 15254-4EN 15725购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS EN 15269-11:2018 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.Cross References:EN 13501-2EN 1993-1-2EN 1363-1EN 13501-2EN 15269-1EN 1634-1EN 1993-1-2EN 15269-1EN 1634-1EN 1363-1ISO 13943EN ISO 13943EN 16035EN 15254-4EN 16034EN 15254-4EN 15725All current amendments available at time of purchase are included with the purchase of this document.
