European foreword

This document (EN 755‑2:2025) 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of an identical text or by endorsement, at the latest by January 2026, and conflicting national standards shall be withdrawn at the latest by January 2026.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights.

This document supersedes EN 755‑2:2016.

Within its programme of work, Technical Committee CEN/TC 132 entrusted CEN/TC 132/WG 5 “Extruded and drawn products” to revise EN 755‑2:2016.

EN 755-2:2025 includes the following significant technical changes with respect to EN 755-2:2016:

addition of EN AW-2033, EN AW-2077, EN AW-4032, EN AW-6050 and EN AW-6061A alloys;
addition of the terms required by the latest CCMC template;
addition of Clause 3 compulsory from the latest CCMC template;
deletion of former Clause 3.3 as part of the table of contents in this document;
correction to temper of EN AW-2024 alloy.

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

CEN/TC 132 affirms its policy that if a patentee refuses to grant licenses on standardized products under reasonable and not discriminatory conditions, this product will be removed from the corresponding document.

Any feedback and questions on this document should be directed to the users’ national standards body. A complete listing of these bodies can be found on the CEN website.
