13、has been prepared by Technical Committee CEN/TC 132 “Aluminium and aluminium alloys”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2008, and
14、 conflicting national standards shall be withdrawn at the latest by September 2008. This document supersedes EN 12020-1:2001. Within its programme of work, Technical committee CEN/TC 132 entrusted CEN/TC 132/WG 5 “Extruded and drawn products“ to revise EN 12020-1:2001 The following technical modific
15、ations have been introduced during the revision: Clause 3: Definition of “order document“ is included Subclause 4.2: An additional Figure 3 is included identifying visible surfaces and weld lines Subclause 5.5: Requirements to streaks and surface texture appearance on visible surfaces in mill finish

BS EN 12020-1:2008 EN 12020-1:2008 (E) 4 1 Scope 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 Figur
21、es 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
22、 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 specia
23、l 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).
