National foreword

This British Standard is the UK implementation of EN 755‑3:2008. It supersedes BS EN 755‑3:1996 which is withdrawn.

The UK participation in its preparation was entrusted to Technical Committee NFE/35, Light metals and their alloys.

A list of organizations represented on this committee can be obtained on request to its secretary.

This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.

Compliance with a British Standard cannot confer immunity from legal obligations.

This British Standard was published under the authority of the Standards Policy and Strategy Committee on 30 April 2008

This European Standard was approved by CEN on 10 February 2008.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN Management Centre or to any CEN member.

This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the CEN Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

Foreword

This document (EN 755‑3:2008) 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of an identical text or by endorsement, at the latest by September 2008, and conflicting national standards shall be withdrawn at the latest by September 2008.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 755‑3:1995.

Within its programme of work, Technical committee CEN/TC 132 entrusted CEN/TC 132/WG 5 "Extruded and drawn products" to revise EN 755‑3:1995.

The following technical modifications have been introduced during the revision:

Clause 2: Alloy EN AW‑3102, EN AW‑6008, EN AW‑6010A, EN AW‑6014, EN AW‑6023, EN AW‑6360, EN AW‑6262A, EN AW‑6065 and EN AW‑6182 are added in Group I
Clause 2: Alloy EN AW‑5049, EN AW‑7108, EN AW‑7108A and EN AW‑7021 are added in Group II

EN 755 comprises the following parts under the general title "Aluminium and aluminium alloys Extruded rod/bar, tube and profiles":

Part 1: Technical conditions for inspection and delivery
Part 2: Mechanical properties
Part 3: Round bars, tolerances on dimensions and form
Part 4: Square bars, tolerances on dimensions and form
Part 5: Rectangular bars, tolerances on dimensions and form
Part 6: Hexagonal bars, tolerances on dimensions and form
Part 7: Seamless tubes, tolerances on dimensions and form
Part 8: Porthole tubes, tolerances on dimensions and form
Part 9: Profiles, tolerances on dimensions and form

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent 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.

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.
