European foreword
This document (EN 12020-1:2022) 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 2022, and conflicting national standards
shall be withdrawn at the latest by September 2022.
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 12020-1:2008.
The following technical modifications have been introduced during the revision:
— Modification of the scope.
The series EN 12020 comprises the following parts under the general title Aluminium and aluminium
alloys - Extruded precision profiles in alloys EN AW-6060 and EN AW-6063:
— Part 1: Technical conditions for inspection and delivery
— Part 2: Tolerances on dimensions and form
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.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the
United Kingdom.
1 Scope
This document specifies technical conditions for inspection and delivery of alloys EN AW-6060
and EN AW-6063 extruded precision profiles manufactured with and without a thermal barrier (see
Figures 1 and 2) and without further surface treatment.
Precision profiles for which this document is applicable are distinguished from extruded profiles for
general applications covered in EN 755-9 by the following characteristics:
— they are designed with mostly uniform wall-thicknesses;
— they are mainly used for mechanical engineering, architectural and automotive (except crash-
elements) applications;
— the maximum weight by meter is 10 kg/m;
— the max. wall-thickness proportion (tmax/tmin) of 3,5.
In the case of profiles, which, due to the complexity of their design are difficult to manufacture and
specify, then special agreements between supplier and purchaser may need to be reached.
NOTE The effect of the thermal barrier material on the dimensional tolerances is covered by EN 12020-2
although the actual thermal barrier material itself is not (see EN 14024).
