21、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of an identical text or by endorsement, at the latest by October 2001, and conflicting national standards shall be withdrawn at the latest by October 2001
22、. Within its programme of work, Technical Committee CEN/TC 132 entrusted CEN/TC 132/WG5, Extruded and drawn products, to prepare the following standard: ? EN 12020-1, Aluminium and aluminium alloys Extruded precision profiles in alloys EN AW-6060 and EN AW-6063 Part 1: Technical conditions for inspe
23、ction and delivery. This standard is part of a set of two standards. The other standard deals with: ? EN 12020-2, Aluminium and aluminium alloys Extruded precision profiles in alloys EN AW-6060 and EN AW-6063 Part 2: Tolerances on dimensions and form. Annex A is normative. According to the CEN/CENEL
24、EC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Swit
25、zerland and the United Kingdom.

26、xtruded precision profiles 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 75
27、5-9 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 300 mm; ? they are made to closer tolerances on dimensions an
28、d form. In the case of profiles which, due to the complexity of their design, are difficult to manufacture and specify, special agreements between purchaser and manufacturer may need to be reached. NOTE 1The thermal barrier material is not covered by this standard. NOTE 2Some of the products listed
29、in the present standard can be subject to patent or patent applications, and their listing herein does not in any way imply the granting of a license under such patent right. CEN/TC 132 affirms it is its policy that in the case when a patentee refuses to grant licenses on standardized standards prod
30、ucts under reasonable and not discriminatory conditions then this product shall be removed from the corresponding standard.

37、t of this European Standard, the terms and definitions given in EN 12258-1 apply. 4 Orders or tenders 4.1 General The order or tender shall define the product required and shall contain the following information: a) the designation of the aluminium alloy as specified in EN 573-3; b) the temper of th
38、e material for delivery as specified in EN 515; c) the application, in particular when surface treatment is intended; this shall be expressly stated on the order (see annex A); d) the number of this European Standard or, if not appropriate, the properties agreed between purchaser and supplier; e) re

42、.2 Reference to a drawing On the basis of the order documentation submitted, the manufacturer shall prepare drawings which are to be checked by the purchaser for accuracy and approved, the profiles then being manufactured in strict accordance with the approved drawing. If for dimensions critical to
43、function tolerances other than those specified in this standard are to be used, they shall be entered in the drawing adjacent to the associated nominal size. This also applies to the tolerances on form. Where profiles are intended for later assembly, it is recommended that the manufacturer is provid
44、ed with a drawing giving appropriate details. Where for manufacturing reasons seams are to be located on visible surfaces, their position shall be indicated by the manufacturer on the drawing. Visible surfaces shall be identified, indicating main and, if necessary, secondary order visible surfaces.
45、For profiles to be surface treated, surfaces and areas that are to be so treated is indicated on the drawing. If the outline of a profile is modified by machining, it is recommended that the final shape is indicated. 5 Requirements 5.1 Production and manufacturing processes Unless otherwise specifie
46、d in the order, the production and manufacturing processes shall be left to the discretion of the producer. Unless it is explicitly stated in the order, no obligation shall be placed on the producer to use the same processes for subsequent or similar orders. 5.2 Quality control The supplier shall be
47、 responsible for the performance of all inspection and tests required by the relevant European Standard and/or the particular specification prior to shipment of the product. If the purchaser wishes to inspect the product at the suppliers works, he shall notify the supplier at the time of placing the
48、 order. 5.3 Chemical composition The chemical composition shall comply with the requirements of EN 573-3. If the purchaser requires special limits for elements not specified in the above standard, these limits shall be stated on the order and after agreement between purchaser and supplier. 5.4 Mecha
49、nical properties The mechanical properties shall comply with the requirements of EN 755-2 or those agreed between purchaser and supplier and stated on the order. Hardness testing may be used for release purposes subject to agreement between purchaser and supplier.
