This document 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 as 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. The following technical modifications have been introduced during the revision: Clause 1: The maximum diameter of the circumscribing circle CD is increased to 350 mm Subclause 2.2: Definition of outer overall dimension O (Figure 3) and tolerances (Table 1) are included Subclause 2.2.4, Table 3: The tolerances on wall thickness of solid and hollow profiles have been modified Subclause 3.1: Requirements to plane parallelism is included Subclause 3.4, Table 7: Requirements to contour tolerances have been modified Subclause 3.5, Table 8: Requirements to twist tolerances have been modified.
