Sie legt die Bezeichnungen dieser Sorten, die Herstellungsbedingungen, die Eigenschaften sowie Kennzeichnungen zur Identifizierung fest.

Aluminium et alliages d'aluminium - Aluminium non allié en lingots pour refusion - Spécifications

La présente Norme européenne spécifie les caractéristiques des nuances d'aluminium non allié en lingots destinés a la refusion.
Elle spécifie la classification et la désignation de ces nuances, leurs conditions de production, leurs caractéristiques et leurs marques d'identification.
NOTE   Des produits cités dans la présente Norme peuvent faire l'objet de brevet ou de demandes de brevets, et leur inclusion dans la présente Norme ne signifie en aucune façon l'attribution d'une licence au regard des droits attachés a de tels brevets.
   Le CEN/TC 132 confirme que dans le cas ou le détenteur d'un brevet refuse de céder des licences sur les produits normalisés sous des conditions raisonnables et non discriminatoires, alors ce produit serait éliminé de la Norme correspondante.

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by endorsement, at the latest by April 2004, and conflicting national standards shall be withdrawn at the latest by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

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).

If special requirements are specified in the order agreed between supplier and purchaser which differ from

requirements specified in this European Standard, then these special requirements shall apply.

5 Requirements
5.1 Production and manufacturing processes

Unless otherwise specified on the order, the production and manufacturing processes shall be left to the discretion

of the manufacturer.

Unless it is explicitly stated on the order, no obligation shall be placed on the manufacturer to use the same

processes for subsequent and similar orders.
5.2 Quality control

additional requirements, 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 unalloyed aluminium with a specified minimum aluminium content, including refined aluminium, shall

be in accordance with the designations and chemical composition given in Table 1.

Each grade of unalloyed aluminium without a specified minimum aluminium content shall be in accordance with the

designations and chemical composition given in Table 2.

The compositions shown in Table 1 and Table 2 are given in mass percent maximum unless otherwise stated.

In interpreting the results of chemical analysis, the number representing the result of the determination of an

element content shall be rounded to the same number of decimal places as the corresponding number in this

standard.

The writing rules for designations and chemical composition shall be applied in accordance with annex A.

If the purchaser requires content limits for elements not specified in this European Standard, these limits shall be

agreed between supplier and purchaser and stated on the order.
5.4 Freedom from defects and foreign material

The ingots shall be free from asbestos and other hazardous foreign material and shall show no indication of

increased radioactivity.

To a standard agreed between supplier and purchaser, the ingots shall be reasonably free from :

a) visible surfaces defects such as grease, dirt, products of corrosion, dross or any other foreign bodies, including

paint apart from that which is approved for marking purposes ;
b) metallic or non-metallic inclusions ;
c) gas porosity.
The ingots can have shrinkage holes or cracks which can retain wat
