本文件规定了在具有和不具有热障碍（见图1和图2）的情况下制造的合金EN AW-6060和EN AW-6063挤出精密型材的检查和交付技术条件，无需进一步的表面处理。 本文档中涉及的精密轮廓与EN 755-9涵盖的一般应用的挤出型材有以下特点: ï，他们主要用于建筑应用; 他们满足对可见表面的表面状况的更严格的要求; ï，外接圆CD的最大直径为350 mm; 它们在尺寸和形状上被制造成更小的公差。 在配置文件的情况下，由于其设计的复杂性难以制造和指定，因此可能需要达成供应商和采购方之间的特殊协议。 注意:EN 12020-2涵盖了热障材料对尺寸公差的影响，尽管实际的热障材料本身不是（参见EN 14024）

This document specifies technical conditions for inspection and delivery of alloys EN AW-6060 and EN AW-6063 extruded precision profiles manufactured with and without a thermal barrier (see Figures 1 and 2) and without further surface treatment. Precision profiles covered in this document are distinguished from extruded profiles for general applications covered in EN 755-9 by the following characteristics:  they are mainly for architectural applications;  they meet more stringent requirements regarding the surface condition of visible surfaces;  the maximum diameter of the circumscribing circle CD is 350 mm;  they are made to closer tolerances on dimensions and form. In the case of profiles, which, due to the complexity of their design are difficult to manufacture and specify, then special agreements between supplier and purchaser may need to be reached. NOTE The effect of the thermal barrier material on the dimensional tolerances is covered by EN 12020-2 although the actual thermal barrier material itself is not (see EN 14024).
