ÖNORM EN 504

This European Standard specifies requirements for roofing products used for assembly into coverings for pitched roofs, made from copper sheet. The standard establishes general characteristics, definitions 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 conform to the requirements or by purchasers to verify that the products conform to the requirements 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 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 copper sheets and strips. No requirements for supporting construction, design of roof system application and execution of connections and flashings are included. NOTE The standard deals partly with flat products, partly with formed (prefabricated) products. Requirements for preformed self-supporting products are given in prEN 506.
