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).

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).

La norme EN 12020-2:2016 se concentre sur les tolérances dimensionnelles et de forme des profils extrudés en aluminium et en alliages d'aluminium, spécifiquement les alliages EN AW-6060 et EN AW-6063. Cette norme européenne constitue un cadre essentiel pour garantir la précision et la qualité des profils extrudés, surtout dans le domaine architectural où les exigences esthétiques et fonctionnelles sont élevées. L'un des principaux atouts de cette norme est son application aux profils extrudés qui doivent répondre à des exigences de surface plus strictes que celles généralement requises pour des applications standards. En définissant des tolérances plus serrées, EN 12020-2:2016 assure que les produits finis non seulement respectent les dimensions requises mais bénéficient également d'une finition de surface optimisée pour une visibilité accrue. De plus, la norme se distingue par sa prise en compte des profils élaborés, pour lesquels des accords spéciaux entre le fournisseur et l'acheteur peuvent être nécessaires en raison de la complexité de leur conception. Cela montre la flexibilité de la norme et son adéquation aux besoins spécifiques des projets architecturaux contemporains. La mention explicite des dimensions maximales, telles que le diamètre maximal du cercle circonscrit fixé à 350 mm, ainsi que l'intégration des exigences liées à l'impact des matériaux de barrière thermique sur les tolérances dimensionnelles, renforcent la pertinence de cette norme pour les fabricants et les utilisateurs finaux. En somme, la norme EN 12020-2:2016 propose un cadre rigoureux et adapté pour les profils extrudés en aluminium qui sont essentiels dans les applications architecturales, garantissant ainsi des niveaux de qualité et de précision nécessaires à la satisfaction des exigences du marché moderne.
EN 12020-2:2016は、アルミニウムおよびアルミニウム合金の押出精密プロファイルに関する非常に重要な標準です。本標準は、特にEN AW-6060およびEN AW-6063合金で製造された押出精密プロファイルの寸法および形状に関する公差を規定しています。この標準は、異なるサーモバリアーの有無に関わらず製造された押出製品に適用され、表面処理が施されていない状態の製品にも対応しています。 本標準の強みは、建築用用途を主に対象としている点です。これは、一般の用途に対する押出プロファイルがEN 755-9で規定されているのに対し、EN 12020-2では、可視面の表面状態により厳しい要求を満たす必要があるためです。さらに、最大直径は350mmの外接円を持つことが許可されており、寸法および形状に関する公差がより厳格に設定されています。 また、デザインが複雑なプロファイルに関しては、製造や仕様が難しい場合には、供給者と購入者の間で特別な合意が必要となることが明記されています。これにより、実際の製造過程における柔軟性が確保され、顧客のニーズに応じたプロファイル製造が可能となります。 さらに、熱バリアー材が寸法公差に与える影響についても文書内で触れられており、熱バリアー材自体の規定は含まれていないことが明確に示されています。この点は、製造者やエンジニアが理解しておくべき重要な情報です。 総じて、EN 12020-2:2016は、アルミニウム及びアルミニウム合金の精密プロファイルの性能基準を確立し、建築分野における要求を満たすための強力なガイドラインとなっています。この標準は、業界の専門家や製造者にとって不可欠なリソースとして、その関連性と重要性は非常に高いと言えるでしょう。
표준 EN 12020-2:2016은 알루미늄 및 알루미늄 합금의 압출 정밀 프로파일에 대한 치수 및 형태의 공차를 규정하는 유럽 표준입니다. 이 표준은 EN AW-6060 및 EN AW-6063 합금을 사용하여 제조된 압출 제품에 적용되며, 열 차단이 있는 제품과 없는 제품 모두에 해당합니다. 특히, 이 표준의 적용 범위는 건축용 응용 분야에 주로 사용되는 정밀 프로파일로 한정되며, 일반적인 응용 분야에 사용되는 압출 프로파일은 EN 755-9 표준에 의해 다루어집니다. 이 표준의 주요 강점 중 하나는 보이는 표면의 표면 상태에 대한 엄격한 요구사항을 충족한다는 점입니다. 또한, 이 표준에 따라 제조된 프로파일은 최대 지름이 350 mm인 circumscribing circle CD를 갖고 있으며, 치수 및 형태에 대해 보다 밀접한 공차를 제공합니다. 이는 고객이 요구하는 품질 기준에 부합하는 정밀성을 보장합니다. 또한, 복잡한 디자인으로 인해 제조 및 규격화가 어려운 프로파일에 대해서는 공급자와 구매자 간에 특별한 계약이 필요할 수 있다는 점이 명시되어 있습니다. 이러한 특별 계약은 고객의 요구사항을 보다 세밀하게 반영하고, 성능 및 디자인의 일관성을 유지할 수 있는 방법으로 작용합니다. 마지막으로, 열 차단 재료가 치수 공차에 미치는 영향을 다루고 있는 점도 EN 12020-2:2016의 중요한 내용입니다. 이 표준은 제품의 품질 및 사용성을 높이는 데 있어 매우 중요한 참고 자료가 됩니다. 따라서 건축 및 정밀 기계 설계에서 알루미늄 압출 프로파일을 사용할 때 이 표준의 준수가 필수적입니다.
Die Norm EN 12020-2:2016 bietet eine präzise Spezifikation der Toleranzen für Abmessungen und Formen von extrudierten Präzisionsprofilen aus Aluminiumlegierungen, insbesondere EN AW-6060 und EN AW-6063. Der Geltungsbereich dieser europäischen Norm ist sehr relevant, da sie spezifische Toleranzen für Produkte definiert, die in der Architektur verwendet werden. Dies ist besonders wichtig, da die Anforderungen an die Oberflächenbeschaffenheit sichtbarer Flächen wesentlich strenger sind als bei allgemeinen Profilen, die in EN 755-9 behandelt werden. Die Stärken der Norm liegen in ihrer detaillierten Definition von Toleranzen, die eine qualitativ hochwertige Produktion von strukturellen Komponenten in der Architekturgestaltung ermöglicht. Durch die Festlegung auf maximal 350 mm Durchmesser des umschreibenden Kreises CD und die Festlegung engerer Toleranzen auf Abmessungen und Form, wird sichergestellt, dass die gefertigten Profile den hohen Ansprüchen der Bauindustrie gerecht werden. Ein weiteres wichtiges Element, das in dieser Norm behandelt wird, ist die Berücksichtigung von Profilen mit thermischen Barrieren. Die Norm bietet Klarheit über die Auswirkungen des Materialeinflusses auf die Maßtoleranzen, obwohl das thermische Barriermaterial selbst nicht explizit behandelt wird. Dies ermöglicht eine umfassende Betrachtung der Fertigung und der technischen Anforderungen, die in speziellen Vereinbarungen zwischen Lieferant und Käufer weiterhin spezifisch ausgehandelt werden können. Insgesamt stellt die EN 12020-2:2016 sicher, dass extrudierte Präzisionsprofile höchste Qualitätsstandards erreichen und ist damit unverzichtbar für alle, die in den Bereichen Architektur und Aluminiumverarbeitung tätig sind.
The standard EN 12020-2:2016 provides a comprehensive framework for establishing tolerances on dimensions and form for extruded precision profiles made from aluminium alloys EN AW-6060 and EN AW-6063. Its scope is particularly relevant to manufacturers and suppliers in the architectural sector, where these precision profiles are predominantly applied. This standard delineates important specifications that differentiate precision profiles from general extruded profiles, notably highlighting the stringent requirements for the surface conditions of visible areas, thereby ensuring aesthetic and functional quality in architectural applications. One of the strengths of this standard lies in its detailed definitions and parameters, which address the close tolerances required for dimensions and form, thus facilitating enhanced manufacturing accuracy and compliance with industry standards. The inclusion of guidance on profiles manufactured both with and without a thermal barrier underscores its practical applicability in diverse production scenarios, while ensuring that the implications of thermal barriers on dimensional tolerances are adequately accounted for. The standard’s provision for complex profile manufacturing, which may necessitate special agreements between suppliers and purchasers, adds a layer of flexibility that can accommodate specific project needs. This aspect ensures that even profiles with intricate designs can adhere to the defined tolerances, fostering a collaborative approach between stakeholders. Overall, the relevance of EN 12020-2:2016 in the field of architectural applications cannot be overstated, as it sets a benchmark for quality and precision in the production of extruded aluminium profiles, promoting consistency and reliability in the supply chain. The emphasis on the stringent requirements, combined with clear delineations of tolerances, positions this standard as an essential reference for industry practitioners aiming to achieve superior results in their projects.
