ÖNORM EN 501

This European Standard specifies requirements for roofing products used for assembly into coverings for pitched roofs, made from Zinc-copper-titanium ) alloy sheet with or without additional coatings. The standard establishes the general characteristics, definitions, labelling and quality control for the products. Products can be prefabricated or semiformed products (e.g. interlocking tiles, slates, flashings) as well as strip, coil, sheet for on-site-formed applications (e.g. standing seam roofs, roll cap). The standard applies to all discontinuously laid and fully supported roofing made of Zinc-copper-titanium alloy (Zn-Cu-Ti). No requirements for application (e.g. methods of fixing, supporting construction, design of roof system, execution of connections and flashings) are included. It defines the requirements for roofing products made from zinc sheets, slit coils, coils and cut lengths to comply with normal service conditions. NOTE : The standard deals partly with flat products, partly with formed (prefabricated) products. Valuable information regarding preformed products is found in prEN 506.
