Roofing products from metal sheet - Specification for self-supporting products of steel, aluminium or stainless steel sheet - Part 1: Steel
This Part of EN 508 specifies requirements for self-supporting roofing products for discontinuous laying made from metallic coated steel sheet with or without additional organic coatings.
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 when purchased before they are 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 roofing 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.
No requirements for supporting construction, design of roof system and execution of connections and flashings are included.
Dachdeckungsprodukte aus Metallblech - Festlegungen für selbsttragende Bedachungselemente aus Stahlblech, Aluminiumblech oder nichtrostendem Stahlblech - Teil 1: Stahl
Dieser Teil von EN 508 legt Anforderungen an selbsttragende Dacheindeckungsprodukte zur überlappenden Verlegung fest, die aus Stahlblech mit metallischem Überzug, 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 außen verwendeten, überlappend verlegten, selbsttragenden Profilbleche, sie gilt nicht für Dachpfannen mit einer Oberfläche < 1 m2 und gepresste Dachpfannen. Diese Profilbleche zur Dacheindeckung sind so ausgelegt, dass sie das Eindringen von Wind, Regen und Schnee in das Gebäude verhindern 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 an Kehlbleche sind nicht Gegenstand dieser Norm.
Produits de couverture en tôle métallique - Spécification pour les plaques de couverture en tôle d'acier, d'aluminium ou d'acier inoxydable - Partie 1 : Acier
Cette partie de l'EN 508 spécifie les prescriptions relatives aux plaques de couverture pour pose en discontinu en tôles d'acier revêtues avec ou sans revêtement organique supplémentaire.
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 profilées extérieures de couverture posées en discontinu à l’exception des tuiles de surface inférieure à 1 m² et produites par estampage. Ces plaques profilées sont conçues pour empêcher le vent, la pluie et la neige de pénétrer dans le bâtiment et pour transmettre à la structure porteuse les charges qui en résultent ainsi que les charges non permanentes dues aux opérations d'entretien.
Aucune prescription relative à la structure porteuse, à la conception du système de toiture et à la réalisation des assemblages et des finitions n'est incluse

Figure 1 — Framework of standards 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. SIST EN 508-1:2008
