SIST EN 508-2:2019

Roofing and cladding products from metal sheet - Specification for self-supporting products of steel, aluminium or stainless steel sheet - Part 2: Aluminium

This part of EN 508 specifies requirements for self-supporting external profiled sheets for roof covering wall cladding, lining and liner tray products for discontinuous laying made from aluminium sheet with or without surface treatment (additional organic coatings or anodising).
The standard establishes general characteristics, definitions, classifications and labelling for the products, together with requirements for the materials from which the products can be manufactured. It is intended to be used either by manufacturers to ensure that their products comply with the requirements or by purchasers to verify that the products comply before they are made available on the market before being despatched from the factory. It specifies the requirements for products which enable them to meet all normal service conditions.
The standard applies to all discontinuously laid self-supporting external profiled sheets for roof covering, wall cladding, lining and liner trays with the exception of tiles with a surface area less than 1 m2 and produced by stamping. These profiled roof sheets are designed to keep wind, rain and snow out of the building, and to transfer any resultant loads and infrequent maintenance loads to the structure.
This standard does not cover products for structural purposes, i.e. it does not cover products used in structural class III (according to EN 1999 1 4), it does not cover products used in constructions of Structural Classes I and II (according to EN 1999 1 4) intended to contribute to the global or partial stability of the building structure by providing racking resistance or resistance of permanent static loads (excluding self-weight of the metal sheet).
No requirements for supporting construction, design of roof system and execution of connections and flashings are included.

Dachdeckungs- und Wandbekleidungselemente aus Metallblech - Spezifikation für selbsttragende Bedachungselemente aus Stahlblech, Aluminiumblech oder nichtrostende Stahlblech - Teil 2: Aluminium

Dieser Teil von EN 508 legt Anforderungen an selbsttragende Dacheindeckungsprodukte zur überlappenden Verlegung fest, die aus Aluminiumblech, mit oder ohne zusätzliche organische Beschichtung, gefertigt wurden. Die Norm legt die allgemeinen Merkmale, Definitionen, Klassifizierungen und die Beschriftung für die Produkte fest, sowie die Anforderungen an die Werkstoffe, aus denen die Produkte hergestellt werden können. Sie ist dafür bestimmt, entweder vom Hersteller verwendet zu werden, um sicherzustellen, dass seine Produkte den Anforderungen entsprechen, oder vom Käufer, um zu überprüfen, ob die Produkte den Anforderungen entsprechen, bevor sie das Werk verlassen. Die Norm legt die Anforderungen an Produkte fest, unter denen die Produkte allen normalen Einsatzbedingungen gerecht werden können. Die Norm gilt für alle bei der Dacheindeckung außen verwendeten, diskontinuierlich verlegten, selbst-tragenden Profilbleche. Diese Profilbleche zur Dacheindeckung sind so ausgelegt, dass das Eindringen von Wind, Regen und Schnee in das Gebäude verhindert wird und dass alle daraus und alle aus nicht ständig durchgeführten Instandhaltungsarbeiten resultierenden Lasten auf das Bauwerk übertragen werden. Anforderungen an die Unterkonstruktion, die Konstruktion des Dachsystems und an die Ausführung der Verbindungen und Kehlbleche sind nicht Gegenstand dieser Norm.

Produits de couverture et bardage en tôle métallique - Spécification pour les plaques de couverture en tôle d'acier, d'aluminium ou d'acier inoxydable - Partie 2 : Aluminium

Cette partie de l'EN 508 spécifie les prescriptions relatives aux produits autoportants de toiture, couverture, bardages intérieurs et extérieurs, cloison pour pose en discontinu en tôle d'aluminium avec ou sans traitement de surface (revêtements organiques supplémentaires ou anodisation).
La norme donne les caractéristiques générales, les définitions, les classifications et l'étiquetage applicables aux produits, de même que les prescriptions relatives aux matériaux à partir desquels les produits peuvent être fabriqués. Elle est destinée à être utilisée soit par des fabricants en vue de démontrer que leurs produits sont conformes aux prescriptions, soit par des acheteurs pour vérifier que les produits sont conformes avant leur expédition de l’usine. Elle spécifie les prescriptions relatives aux produits pour leur permettre de répondre à toutes les conditions normales en service.
La norme s'applique à toutes les plaques autoportantes profilées extérieures de couverture, de bardages intérieurs et extérieurs, de cloisons posées en discontinu, à l'exception des dalles d'une surface inférieure à 1 m2 et produites par emboutissage.  Ces plaques profilées sont conçues pour empêcher le vent, la pluie et la neige de pénétrer dans le bâtiment et transmettent à la structure porteuse les charges qui en résultent ainsi que les charges occasionnelles dues aux opérations d'entretien.
La présente norme ne couvre pas les produits pour applications structurelles, c'est-à-dire qu'elle  ne couvre pas les produits utilisés dans la classe structurelle III (selon EN 1999-1-4), elle ne couvre pas les produits destinés aux constructions de classes structurelles I et II (selon EN 1999-1-4) destinés à contribuer à la stabilité globale ou partielle de la structure du bâtiment ou apportant un contreventement ou une résistance aux charges statiques permanentes (à l'exclusion du poids propre de la plaque métallique).
Aucune exigence relative à la structure porteuse, à la conception du système de toiture et à la réalisation des assemblages et des finitions n'est incluse.

In this standard the performance of the product has been defined in terms of calculation and a number
of type tests.
The performance of a roof constructed with these products depends not only on the properties of the
product as required by this standard, but also on the design, construction and performance of the roof
as a whole in relation to the environment and conditions of use.

1 Scope
This part of EN 508 specifies requirements for self-supporting external profiled sheets for roof covering
wall cladding, lining and liner tray products for discontinuous laying made from aluminium sheet with
or without surface treatment (additional organic coatings or anodising).
The standard establishes general characteristics, definitions, classifications and labelling for the
products, together with requirements for the materials from which the products can be manufactured.
It is intended to be used either by manufacturers to ensure that their products comply with the
requirements or by purchasers to verify that the products comply before they are made available on the
market before being despatched from the factory. It specifies the requirements for products which
enable them to meet all normal service conditions.
The standard applies to all discontinuously laid self-supporting external profiled sheets for roof
covering, wall cladding, lining and liner trays with the exception of tiles with a surface area less than
2
1 m and produced by stamping. These profiled roof sheets are designed to keep wind, rain and snow
out of the building, and to transfer any resultant loads and infrequent maintenance loads to the
structure.
This standard does not cover products for structural purposes, i.e. it does not cover products used in
structural class III (according to EN 1999-1-4), it does not cover products used in constructions of
Structural Classes I and II (according to EN 1999-1-4) intended to contribute to the global or partial
stability of the building structure by providing racking resistance or resistance of permanent static
loads (excluding self-weight of the metal sheet).
No requirements for supporting construction, design of roof system and execution of connections and
flashings are included.
