Foreword
This document (EN 573-1:2004) 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text or by endorsement, at the latest by May 2005, and conflicting national standards shall be withdrawn at the
latest by May 2005.
This document supersedes EN 573-1:1994. It contains only minor modifications which clarify its technical
content without modifying it.
This standard is part of set of five standards. The other standards deal with:
EN 573-2, Aluminium and aluminium alloys – Chemical composition and form of wrought products –
Part 2: Chemical symbol based designation system.
EN 573-3, Aluminium and aluminium alloys – Chemical composition and form of wrought products –
Part 3: Chemical composition.
EN 573-4, Aluminium and aluminium alloys – Chemical composition and form of wrought products –
Part 4: Forms of products.
prEN 573-5, Aluminium and aluminium alloys – Chemical composition and form of wrought products –
Part 5: Codification of standardized wrought products.
The wording has been clarified in accordance with the "International Alloy Designations and Chemical
Composition Limits for Wrought Aluminum and Wrought Aluminum Alloys".
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
and United Kingdom.
1 Scope
This document specifies a European designation system of wrought aluminium and aluminium alloys, based
on an international designation system, and the procedure to obtain such international designation.
It is in accordance with the "Recommendation" dated December 15, 1970, as revised in March 2002, for an
International Designation System for Wrought Aluminum and Wrought Aluminum Alloys issued by the
Aluminum Association, Washington DC 20006, USA.
This standard applies to wrought products and to ingots intended to be wrought.
