Aluminium and aluminium alloys - Extruded precision profiles in alloys EN AW-6060 and EN AW-6063 - Part 2: Tolerances on dimensions and form

This European Standard 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).

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

Diese Europäische Norm 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. Sie gilt für stranggepresste Erzeugnisse, die ohne weitere Oberflächen¬behandlung 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 (en: diameter of the circumscribing circle (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 Hersteller und Käufer notwendig sein.
ANMERKUNG   Der Einfluss des Materials für die Wärmedämmung auf die Grenzabmaße wird in diesem Dokument berücksichtigt, wenngleich das eigentliche Material für die Wärmedämmung nicht enthalten ist (siehe EN 14024).

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 présente Norme européenne 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 barrière thermique (voir Figures 1 et 2). Elle s’applique aux produits filés fournis sans traitement de surface spécifique. Les profilés de précision couverts par cette norme sont distincts des produits filés pour application générale couverts par l’EN 755-9 par les caractéristiques suivantes :
-   ils sont principalement destinés aux applications architecturales ;
-   ils satisfont à des exigences plus rigoureuses en ce qui concerne l’état des surfaces visibles ;
-   le diamètre maximal du cercle circonscrit CD est de 350 mm ;
-   ils sont fabriqués avec des tolérances sur dimensions et forme plus serrées.
Dans le cas de profilés qui, en raison de la complexité de leur conception, sont difficiles à fabriquer et à spécifier, des accords spéciaux sont à trouver entre l’acheteur et le fournisseur.
NOTE   Les effets du matériau de barrière thermique sur les tolérances dimensionnelles sont couverts par le présent document, même si le matériau de la barrière thermique lui-même ne l’est pas (voir l'EN 14024).

Aluminij in aluminijeve zlitine - Precizni iztiskani profili v zlitinah EN AW-6060 in EN AW-6063 - 2. del: Tolerance mer in oblike

Ta Evropski standard določa tolerance mer in oblike preciznih iztiskanih profilov v zlitinah EN AW-6060 in EN AW-6063, izdelanih s termično prevleko ali brez nje (glej sliki 1 in 2). Uporablja se za iztiskane proizvode, dobavljene brez nadaljnje površinske obdelave. Precizni profili, ki jih zajema ta standard, se razlikujejo od iztiskanih profilov za splošno uporabo, ki so zajeti v standardu EN 755-9, po naslednjih lastnostih:
– namenjeni so zlasti arhitekturni uporabi;
– izpolnjujejo strožje zahteve glede stanja vidnih površin;
– največji premer odprtine CD je 350 mm;
– izdelani so z manjšimi tolerancami mer in oblike.
Pri profilih, ki jih je zaradi kompleksnosti zasnove težko izdelati in določiti, je morda treba doseči posebne dogovore med dobaviteljem in kupcem.
OPOMBA: Učinek termične prevleke na tolerance mer je zajet v tem dokumentu, čeprav sam material termične prevleke ni zajet (glej standard EN 14024).
