本欧洲标准规定了在具有和不具有热障碍的情况下制造的合金EN AW-6060和EN AW-6063中的挤压精密型材的尺寸和形状公差（见图1和图2）。适用于未经进一步表面处理的挤出产品。本标准涵盖的精密型材与EN 755-9涵盖的一般应用的挤出型材有以下特点: - 它们主要用于建筑应用; - 它们满足对可见表面的表面状况的更严格的要求; - 外接圆CD的最大直径为350 mm; - 它们在尺寸和形状上被制成更小的公差。 在配置文件的情况下，由于其设计的复杂性难以制造和规定，因此可能需要达成供应商和采购方之间的特殊协议。 注意尽管实际的热障材料本身不是（参见EN 14024），但是本文件涵盖了热障材料对尺寸公差的影响

This European Standard specifies tolerances on dimensions and form of extruded precision profiles, in alloys EN AW-6060 and EN AW-6063 manufactured with and without a thermal barrier (see Figures 1 and 2). It applies to extruded products supplied without further surface treatment. Precision profiles covered in this standard 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 this document although the actual thermal barrier material itself is not (see EN 14024).
