Foreword
This document EN 576:2003 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of an identical text or by endorsement, at the latest by April 2004, and conflicting national standards shall be withdrawn at the latest by April 2004.
Within its programme of work, Technical Committee CEN/TC 132 entrusted CEN/TC 132/WG 1 "Liquid metal, unalloyed and alloyed ingots" to prepare the following standard :
EN 576, Aluminium and aluminium alloys - Unalloyed aluminium ingots for remelting – Specifications.
This document supersedes EN 576:1995.
This revised version specifies a modified list of grades of unalloyed aluminium together with a new designation system which is specified in a new normative annex. The revision aligns this European Standard with common rules of the international trade of unalloyed aluminium which are based on the designation system of the Aluminum Association.
Annex A is normative.
According to the CEN/CENELEC 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, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom.

1 Scope
This European Standard specifies the requirements for grades of unalloyed aluminium in the form of ingots for remelting.
It specifies the designations for these grades, the conditions in which they are produced, their properties and the marks by which they are identified.
NOTE Some of the products listed 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 licence under such patent right.
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 and not discriminatory conditions, then this product shall be removed from the corresponding standard.
2 Normative references

These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).
