This European
13、 Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2009, and conflicting national standards shall be withdrawn at the latest by November 2009. Attention is drawn to the possibility that some of the eleme
14、nts of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. CEN/TC 132 affirms it is its policy that in the case when a patentee refuses to grant licenses on standardised standard products under reasonable
15、and not discriminatory conditions, then this product shall be removed from the corresponding document. This document will supersede EN 14121:2003. Within its programme of work, CEN/TC 132 entrusted CEN/TC 132/WG 7 “Sheets, strips and plates“ to revise EN 14121. The following modifications were intro
16、duced in the standard: Table 1: EN AW-1370, EN AW-1370A, EN AW-6101B were added. Table 1: the value of the electrical conductivity of EN AW-1350 and EN AW-1350A, in temper H19, was corrected to 34,0. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the follo
17、wing countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slov

BS EN 14121:2009EN 14121:2009 (E) 7 5.5 Freedom from defects The product shall be free from defects prejudicial to its suitable and proper use. It shall have a smooth and clean surface. However
35、, small surface defects such as light scratches, indentations, laminations, stripes, roll marks, discolorations and non-uniform surface appearance resulting from heat treatment, etc., which cannot always be totally avoided, are generally permitted on both sides of the product. Whilst an operation de
36、signed to mask a fault is not permitted, the elimination of a superficial fault is permissible, provided that the dimensional tolerances and material properties continue to meet the specifications. 5.6 Tolerances on dimensions and form The tolerances on dimensions and form shall be in conformity wit
37、h EN 485-3 or EN 485-4. Other tolerances on dimensions and form shall be agreed between manufacturer and purchaser. 5.7 Other properties Additional requirements for properties such as hardness, bending ability etc., shall be agreed between manufacturer and purchaser. 6 Test methods 6.1 Chemical comp
38、osition The methods of analysis shall be at the discretion of the manufacturer. In case of dispute concerning the chemical composition, a referee analysis shall be carried out by methods agreed between manufacturer and purchaser. The results obtained by these methods shall be accepted. 6.2 Tensile t
39、est The tensile test shall be carried out in accordance with EN 10002-1. 6.3 Electrical conductivity The determination of electrical conductivity shall be carried out in accordance with a documented procedure giving details, such as a temperature between 15 C and 25 C. This procedure shall address t
40、he precision of the measurements and possible errors. Induction methods can be used for measurement of electrical conductivity, according to EN 2004-1, but for thin products, care shall be taken to avoid inaccuracy due to the penetration depth of the electrical field. 6.4 Measurement of dimensions T
41、he dimensions shall be measured by means of measuring instruments which are of an accuracy consistent with that of dimensions and the dimensional tolerances. All dimensions shall be checked at the ambient temperature in the workshop or laboratory, and, in case of dispute, at a temperature between 15
42、 C and 25 C. 6.5 Surface finish Unless otherwise specified, examination of surface finish shall be carried out without the assistance of magnifying apparatus on products before delivery. BS EN 14121:2009EN 14121:2009 (E) 8 6.6 Other tests If other mechanical or physical tests are required, these sha
43、ll be agreed between manufacturer and purchaser. These tests shall be carried out either in accordance with the existing European Standards or agreed upon by manufacturer and purchaser. The following standards may be used as guidelines: a) the Brinell hardness (HBW) in accordance with EN ISO 6506-1;
44、 b) erichsen test: in accordance with ISO 8490; c) earing test: in accordance with EN 1669. 7 Inspection documents When requested by the purchaser and agreed by the manufacturer, the manufacturer shall provide the appropriate inspection document in accordance with EN 10204. 8 Marking of products Mar
45、king of products shall be undertaken when agreed between manufacturer and purchaser and stated on the order. This marking shall not adversely affect the final use of the product. 9 Packing Unless otherwise specified in European Standards relating to special products or specified in the order, the me
46、thod of packing shall be determined by the manufacturer who shall take all suitable precautions to ensure that, under the usual conditions of transportation, the products will be delivered in a condition suitable for use. 10 Arbitration In cases of dispute concerning conformity with the requirements
47、 of this European Standard and before any decision is made to reject the products, testing and examination shall be carried out by an arbitrator chosen by mutual agreement between manufacturer and purchaser. The arbitrators decision shall be final. BS EN 14121:2009EN 14121:2009 (E) 9 Bibliography 1
