Foreword
This document (EN 754-1:2008) 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withdrawn at the latest by September 2008.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 754-1:1997.
Within its programme of work, Technical committee CEN/TC 132 entrusted CEN/TC 132/WG 5 "Extruded and
drawn products" to revise EN 754-1:1997.
The following technical modifications have been introduced during the revision:
 Clause 1: Scope is clarified with respect to what is not included
 Clause 3: Definition of order document is included
 Clause 4: The order document shall contain information about application especially for products to be
anodised
 Subclauses 5.4 and 6.2.3: Provisions regarding Brinell hardness testing is included
 Subclauses 5.7 and 6.2.6: Requirements to stress corrosion cracking resistance is included (from former
Annex A in Part 2)
 Subclause 6.1.1: For samples for chemical analysis reference is made to EN 14361
 Subclause 6.1.3.3: For shapes and dimensions of test pieces reference is made to EN 10002-1 (and
former Annex A is deleted)
 Clause 7: For inspection documents reference is made to EN 10204
 Annex B: Resistance to stress corrosion cracking – Electrical conductivity is added (taken from former
Part 2)
EN 754 comprises the following parts under the general title "Aluminium and aluminium alloys — Cold drawn
rod/bar and tube ":

rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
CEN/TC 132 affirms it is its policy that in the case when a patentee refuses to grant licenses on standardized
standards products under reasonable and not discriminatory conditions then this product shall be removed
from the corresponding standard.
