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 of EN 12020 specifies tolerances on dimensions and form of extruded precision profiles, in alloys EN AW-6060 and EN AW-6063 manufactured with or without a thermal barrier (see Figure 1 and 2). It applies to as extruded products supplied without further surface treatment. Precision profiles covered in this standard are distinguished 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 350 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, then special agreements between supplier and purchaser may need to be reached.

Aluminium und Aluminiumlegierungen - Stranggepresste Präzisionsprofile aus Legierungen EN AW-6060 und EN AW-6063 - Teil 2: Grenzabmaße und Formtoleranzen

Dieses Dokument 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. Es 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 beträgt 350 mm;
-   sie weisen engere Grenzabmaße und Formtoleranzen auf.
Bei Profilen, die aufgrund ihrer komplexen Konstruktion schwierig herzustellen und zu spezifizieren sind, können besondere Vereinbarungen zwischen Lieferer und Käufer notwendig sein.
ANMERKUNG   Der Einfluss des Materials für die Wärmedämmung auf die Grenzabmaße wird in prEN 12020 2 berücksichtigt, wenngleich das eigentliche Material für die Wärmedämmung nicht enthalten ist (siehe EN 14024 [1]).

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

Le présent document 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 :
-   ils sont principalement destinés pour applications architecturales ;
-   ils rencontrent des exigences plus rigoureuses en ce qui concerne l'état de surface des surfaces visibles ;
-   le diametre du cercle circonscrit CD est de 350 mm ;
-   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   Les effets du matériau de barriere thermique sur les tolérances dimensionnelles est couvert par ce document, cependant que le matériau de la barriere thermique lui-meme ne l'est pas (voir EN 14024 [1]).

EN 12020-2:2008 (E) 4 1 Scope This document specifies 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). It applies to extruded products supplied without further surface treatment. Precision profiles covered in this standard are distinguished 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 350 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, 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 this document although the actual thermal barrier material itself is not (see EN 14024).
