23、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 Figures 1 and 2) and without further surface treatment. Precision profiles covered in this

24、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 circ

25、umscribing 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

26、 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).

35、tion 4.1 General The order document shall contain the following: 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 particula

36、r, when surface treatment is intended; this shall be expressly 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

37、 and any other relevant information; f) length: fixed or random, for random lengths minimum and maximum shall be specified, an allowance for process contact points of surface treatment may be necessary; g) quantity: mass or number of pieces or total length, tolerance on quantity; h) special requirem

38、ents: any special requirements agreed between the supplier and purchaser, agreement on plane parallelism, any requirement for inspection documents, marking of products, reference to other standards, if tolerances on dimensions and form differ from those specified in EN 12020-2, additional or special

DIN EN 12020-1:2008-06 EN 12020-1:2008 (E) 7 4.2 Reference to a drawing On the basis of the order document, the manufacturer shall prepare drawings, which are to be checked by the purchaser for accuracy, and

40、 approved, the profiles then being manufactured in strict accordance with the approved drawing. If for dimensions critical to function, tolerances other than those specified in this document are to be used, they shall be entered in the drawing adjacent to the associated nominal size. This also appli

41、es to the tolerances on form. Where profiles are intended for later assembly, it is recommended that the manufacturer is provided with a drawing giving appropriate details. Where for manufacturing reasons weld lines are to be located on visible surfaces their position or approximate area of appearan

42、ce should be indicated by the manufacturer on the drawing. Visible surfaces shall be identified, indicating main and, if necessary, secondary order visible surfaces. Key 1 visible surface 2 area of probable appearance of weld lines 3 area of probable appearance of T-joint streaks Figure 3 Marking of

43、 visible surfaces of approximate area of appearance of weld lines and T-joint streaks For profiles intended for surface treatment, surfaces and areas that are to be so treated should be indicated on the drawing. If the outline of a profile is modified by machining, it is recommended that the final s

44、hape is also indicated. 5 Requirements 5.1 Production and manufacturing processes Unless otherwise specified in the order document, the production and manufacturing processes shall be left to the discretion of the manufacturer. Unless it is explicitly stated in the order document, no obligation shal

45、l be placed on the manufacturer to use the same processes for subsequent or similar orders. DIN EN 12020-1:2008-06 EN 12020-1:2008 (E) 8 5.2 Quality control The supplier shall be responsible for the performance of all inspection and tests required by the relevant European Standard and/or the particu

46、lar specification prior to shipment of the product. If the purchaser wishes to inspect the product at the manufacturers works, he shall notify the supplier at the time of placing the order. 5.3 Chemical composition limit The chemical composition limit shall be in conformity with the requirements spe

47、cified in EN 573-3.
