Roofing 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 roofing products for discontinuous laying made from aluminium 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 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. 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 - Spezifikation für selbsttragende Bedachungselemente aus Stahlblech, Aluminiumblech oder nichtrostendem 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 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 plaques de couverture pour pose en discontinu en tôle d'aluminium 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. 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. 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 roofing products for discontinuous laying made
from aluminium 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 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. 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.

NOTE 2 It should be noted that different coating systems behave in different ways under various climatic conditions.
The primer and/or adhesive should be chosen taking into account which type of substrate, pretreatment and top coat are
used.
Reverse side painting or coating is used if being required for handling and storage reasons as well as for
corrosion protection in some installation conditions.
Performance and test methods for coil coated aluminium shall be in accordance with EN 1396.
NOTE 3 Special coatings or films may be applied to the reverse side to reduce the dripping of moisture caused by
condensation.
4.3 Products
4.3.1 Mechanical resistance
The product shall resist the design loads from snow, wind and maintenance. These loads shall be factored
such that they will not impair the performance of the roof.
NOTE The load level, the levels of safety and permissible deflection are defined in national building regulations.
4.3.2 Calculation and tests of mechanical resistance
The mechanical performance of the product shall be stated by the manufacturer, together with details of how
the values were determined in accordance with the national regulations of the country where the product is to
be used.
NOTE 1 For calculation and testing either national regulations or EN 1999-1-4 may be used.
NOTE 2 Calculation and test methods referred to in this EN mainly deal with trapezoidal sheets. Tiles, standing seam
sheets and concealed fix sheets are used in proprietary roofing systems, no structural requirements are given within this
standard for these products. These products should normally be designed by testing.
4.3.3. Dimensions
4.3.3.1 General
The dimensions of the product shall be fixed in order that the roof constructed with these products can fulfil its
functions.
4.3.3.2 Thickness
Measurements of the thickness of manufactured products such as profiled sheets shall be made not less than
10 mm from the edges in accordance with EN 485-4.
Products shall be classified according to tolerance on thickness as follows:
class 1: full minus nominal normal tolerance according to EN 485-4;
class 2: 1/2 minus nominal normal tolerance according to EN 485-4;
class 3: zero minus tolerance.
NOTE 1 For products of class 3, mechanical resistance is calculated using the minimum thickness of the aluminium
core guaranteed by the manufacturer.
NOTE 2 National regulations will state the class of product that it will be possible to use.
