4、een 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 February 2010, and confl
5、icting national standards shall be withdrawn at the latest by February 2010. Attention is drawn to the possibility that some of the elements 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. This docu
6、ment supersedes EN 487:1993. Within its programme of work, Technical Committee CEN/TC 132 entrusted CEN/TC 132/WG 2 “Extrusion billets and rolling ingots“ to revise EN 487:1993. CEN/TC 132 affirms its policy that in the case when a patentee refuses to grant licences on standardised standard products
7、 under reasonable and not discriminatory conditions, then this product shall be removed from the corresponding standard. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium,

13、ectrometric analysis 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 12258-1:1998 and the following apply. 3.1 heat quantity of liquid metal that has simultaneously undergone the same preparatory treatment in the furnace before the casting operation 4
14、 Ordering information The ordering information shall define the product required and shall contain the following: a) the form of the product (rolling ingot); b) the designation of the aluminium or aluminium alloy according to EN 573-1 and 573-2 (or the purchaser alloy designation after agreement bet
15、ween supplier and purchaser). Tighter limits than the composition limits stated in EN 573-3 may be specified as required; c) whether as cast or homogenized. The homogenizing parameters should be agreed between the supplier and the purchaser; EN 487:2009 (E) 5 d) the number of this European Standard;
16、 e) the dimensions and shape of the product: 1) nominal thickness (expressed in millimetres); 2) nominal width (expressed in millimetres); 3) nominal length and tolerance if different from standard (expressed in millimetres); 4) cross sectional profile details or drawing number (expressed in millime
17、tres); f) sawing code (see 5.6.4); g) whether rolling ingots are to be supplied scalped or not; h) whether the rolling ingots are scalped or not before hot rolling; i) end use (e.g. foil, packaging) (see 5.1); j) quantity: 1) mass (in metric tonnes) or number of pieces; 2) quantity tolerances if req
18、uired; k) any requirements for inspection documents (see Clause 7); l) any additional requirements agreed between supplier and purchaser (see Clause 7). 5 Requirements 5.1 Production and manufacturing processes The product requirements as formulated in this clause normally are not sufficient for rol
19、ling ingots to meet the purchasers requirements for rolled products. Therefore, the purchaser shall give the manufacturer full details concerning the end use requirements, so that the manufacturing conditions of the manufacturer may best be adjusted to fulfil the requirements. It is recommended that
20、 trial quantities be produced to confirm that the end use requirements are met. It is also recommended that the purchaser asks the manufacturer to advise of any significant change in the manufacturing processes which may affect the quality of the final product. It is recommended that a quality assur
21、ance system be implemented as described in EN ISO 9000 and EN ISO 9004. 5.2 Chemical composition The chemical composition of the ingots shall conform to the compositions specified in EN 573-3. It is recommended that tighter composition limits than those given in EN 573-3 be agreed between purchaser
22、and supplier as required. Control of alkali metals and other specific trace elements is recommended: a) sodium and calcium for magnesium alloys; EN 487:2009 (E) 6 b) lithium for foil end use alloys; c) beryllium. The maximum hydrogen content and the related measuring method should be agreed between
