EN 1676:2010 (E) 3 Foreword This document (EN 1676:2010) has been 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of an identical text or by endorsement, at the latest by September 2010, and conflicting national standards shall be withdrawn at the latest by September 2010.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. CEN/TC 132 affirms it is its policy that in the case when a patentee refuses to grant licences on standardised standard products under reasonable and not discriminatory conditions, then this product shall be removed from the corresponding standard. This document supersedes EN 1676:1996. Within its programme of work, Technical Committee CEN/TC 132 entrusted CEN/TC 132/WG 10 "Castings" to revise EN 1676:1996. In addition to some additional minor and editorial changes, the following technical modifications were introduced during the revision: a) New normative references were added (EN 12258-1, EN 14242 and EN 14361).

Unless it is explicitly stated in the order document, no obligation shall be placed on the manufacturer to use the same processes for subsequent and similar orders. However, the supplier should inform the purchaser of any change that may affect the quality of the ingots or the final products. 5.2 Quality control The supplier shall be responsible for carrying out 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 supplier's works, he shall stipulate this at the time of placing the order. 5.3 Chemical composition Each grade of alloyed aluminium ingot for remelting shall be in accordance with the designations and chemical composition specified in Table 1. NOTE For unalloyed aluminium ingots, see EN 576. For alloys that are not in Table 1, the writing rules for designations and chemical compositions, as specified in EN 1780-1, EN 1780-2 and EN 1780-3, shall be applied. If the purchaser requires content limits for elements not specified in this European Standard, these limits shall be stated on the order document, after agreement between supplier and purchaser.
