Aluminium and aluminium alloys - Extruded precision profiles in alloys EN AW-6060 and EN AW-6063 - Part 2: Tolerances on dimensions and form
This part prEN 12020 specifies the tolerances on dimensions and form of extruded precision profiles, in alloys EN AW-6060 and EN AW-6063 manufactured with and without a thermal barrier (see figures 1 and 2). This applies to as extruded products supplied without further surface treatment.
Aluminium und Aluminiumlegierungen - Stranggepresste Präzisionsprofile aus Legierungen EN AW-6060 und EN AW-6063 - Teil 2: Grenzabmaße und Formtoleranzen
Dieser Teil von EN 12020 legt die Grenzabmaße und Formtoleranzen für stranggepreßte Präzisionsprofile aus den Legierungen EN AW-6060 und EN AW-6063, die mit oder ohne Wärmedämmung (siehe Bild 1 bzw. Bild 2) hergestellt werden, fest. Er gilt für stranggepreßte Erzeugnisse, die ohne weitere Oberflächenbehandlung hergestellt werden.Die Präzisionsprofile, die Gegenstand dieser Norm sind, unterscheiden sich von den stranggepressten Profilen für allgemeine Anwendungen nach EN 755-9 wie folgt:
- sie sind hauptsächlich für Anwendungen im Architekturbereich vorgesehen;
- sie entsprechen strengeren Anforderungen im Hinblick auf den Zustand der sichtbaren Oberflächen;
- der maximale Durchmesser des Umschlingungskreises CD ist 300mm;
- sei weisen engere Grendzabmaße und Formtoleranzen auf.
Bei Profilen, die aufgrund ihrer komplexen Konstruktion schwierig herzustellen und zu spezifizieren sind, können besondere Vereinbarungen zwischen Kunden und Hersteller notwendig sein.
Aluminium et alliages d'aluminium - Profilés de précision filés en alliages EN AW-6060 et EN AW-6063 - Partie 2: Tolérances sur dimensions et forme
La présent partie de la norme EN 12020 spécifie les tolérances sur dimensions et forme des profilés filés de précision en alliages EN AW-6060 et EN AW-6063 fabriqués avec ou sans barriere thermique (voir Figures 1 et 2). Elle s'applique aux produits filés fournis sans traitement de surface spécifique. Les profilés de précision couverts dans cette norme sont distincts des produits filés pour application générale couverts dans l'EN 755-9 par les caractéristiques suivantes :
3 ils sont principalement destinés pour applications architecturales ;
3 ils rencontrent des exigences plus rigoureuses en ce qui concerne l'état de surface des surfaces visibles ;
3 le diametre du cercle circonscrit CD est de 300 mm ;
3 ils sont fabriqués avec des tolérances sur les dimensions et forme plus serrées.
Dans le cas de profilés lesquels, en raison de la complexité de leurs dessins, sont difficiles a fabriquer et a spécifier, des accords spéciaux entre acheteur et fabricant sont a rechercher.
NOTE 1 Le matériau de barriere thermique n'est pas couvert par cette norme.
NOTE 2 Des produits cités dans la présente norme peuvent faire l'objet de brevet ou de demandes de brevets, et leur inclusion dans la présente norme ne doit en aucune façon considérée comme l'attribution d'une licence au regard des droits attachés a de tels brevets.
Le CEN/TC 132 confirme que dans le cas ou le détenteur d'un brevet refuse de céder des licences sur les produits normalisés sous des conditions raisonnables et non discriminatoires, alors ce produit serait éliminé de la norme correspondante

Page 4EN 12020-2:20011 ScopeThis part of EN 12020 specifies tolerances on dimensions and form of extruded precision profiles, in alloysEN AW-6060 and EN AW-6063 manufactured with and without a thermal barrier (see Figures 1 and 2). It applies toas extruded products supplied without further surface treatment. Precision profiles covered in this standard aredistinguished from extruded profiles for general applications covered in EN 755-9 by the following characteristics : they are mainly for architectural applications ; they meet more stringent requirements regarding the surface condition of visible surfaces ; the maximum diameter of the circumscribing circle CD is 300 mm ; they are made to closer tolerances on dimensions and form.In the case of profiles which, due to the complexity of their design, are difficult to manufacture and specify, thenspecial agreements between purchaser and manufacturer may need to be reached.NOTE 1The thermal barrier material is not covered by this standard.NOTE 2Some of the products listed in the present standard can be subject to patent or patent applications, and their listingherein does not in any way imply the granting of a licence under such patent right.CEN/TC 132 affirms it is its policy that in the case when a patentee refuses to grant licences on standardised standard productsunder reasonable and not discriminatory conditions then this product shall be removed from the corresponding standard.Dimensions in millimetresKey1Thermal barrierFigure 1 — Profile without thermal barrier(example)Figure 2 — Profile with thermal barrier(example)
