Precision profiles covered in this document are distinguished from extruded profil

22、es 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 t

23、o 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 dimensiona

24、l tolerances is covered by EN 12020-2 although the actual thermal barrier material itself is not (see EN 14024).

33、lowing: a) the designation of the aluminium alloy (EN AW-6060 or EN AW-6063); b) the temper of the material for delivery in accordance with EN 755-2 (The temper designations to be used are according to EN 515); c) the application, in particular, when surface treatment is intended; this shall be expr

34、essly stated on the order document; d) reference to this document (EN 12020-1); e) reference to a drawing defining the product (see 4.2), cross sectional dimensions, mass per meter calculated on nominal section dimensions, surface requirements and any other relevant information; f) length: fixed or
