Foreword
This document (EN 755-6:2008) 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 2008, and conflicting national standards shall be
withdrawn at the latest by September 2008.
This document supersedes EN 755-6:1995.
Within its programme of work, Technical committee CEN/TC 132 entrusted CEN/TC 132/WG 5 "Extruded and
drawn products" to revise EN 755-6:1995.
The following technical modifications have been introduced during the revision:
 Clause 2: Alloys EN AW-3102, EN AW-6008, EN AW-6010A, EN AW-6014, EN AW-6023, EN AW-6360,
