This European Standard specifies requirements for roofing products used for assembly into coverings for pitched roofs, made from aluminium sheet with or without additional organic coatings. The standard establishes general characteristics, definitions and labelling of 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. Products can be prefabricated or semiformed products as well as strip, coil and sheet for on-site-formed applications (e.g. standing seam roofs). The standard applies to all discontinuously laid and fully supported roofing products made of aluminium sheets. No requirements for supporting construction, design of roof system and execution of connections and flashings are included. NOTE The standard deals partly with flat products, partly with preformed (prefabricated) products. Requirements for preformed self-supporting products are given in prEN 508-2.
