Foreword

This document (EN 570:2007) 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by endorsement, at the latest by July 2007, and conflicting national standards shall be withdrawn at the latest by

July 2007.
This document supersedes EN 570:1994.

Within its programme of work, Technical Committee CEN/TC 132 entrusted CEN/TC 132/WG 11 "Slugs for impact

extrusion" to revise EN 570:1994.
The following technical modifications have been introduced during the revision:

 Clause 2: References to EN 754-3, EN 754-7, EN 754-8, EN 755-3, EN 755-7 and EN 755-8 added;

 Clause 4: Text modified;

 Clause 5: Text in 5.1.1 modified, former Table 2 deleted and replaced by reference to EN 755-3, former

Table 4 deleted and replaced by references to EN 755-7 and EN 755-8;

3 Terms and definitions
For the purposes of this document the following terms and definitions apply.
3.1
slug

piece of metal of uniform thickness of regular or irregular shape taken from a wrought product, usually for impact

extrusion with or without a centre hole
