Roofing products of metal Self supporting products Fully supported produ

20、cts Zinc EN 501 Stainless steel EN 502 Copper EN 504 Steel EN 505 Aluminium EN 507 References regarding Materials Quality assurance Figure 1 Framework of standards In this European Standard, the performance of the product has been defined in terms of a number of type tests. The performance of a roof

21、 constructed with these products depends not only on the properties of the product as it is required by this European Standard, but also on the design, construction and performance of the roof as a whole in relation to the environment and conditions of use. Metallic coated steel sheet can be easily

22、fabricated. It can be sheared, punched, pressed, drawn, folded, roll-formed without difficulty within the given limits of the properties listed in the respective material specifications. Coil coated sheet can be fabricated like metallic coated steel sheet in most applications, but minimum bend radii

23、, design of forming tools, process temperature etc are chosen according to material properties. BS EN 505:2013EN 505:2013 (E) 5 1 Scope This European Standard specifies requirements for roofing products used for assembly into coverings for pitched roofs, made from metallic coated steel sheet with or

24、 without additional organic coatings. The European 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 thei

25、r 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

26、 strip, coil and sheet for on-site-formed applications (e.g. standing-seam and clip fixroofs). The European Standard applies to all discontinuously laid and fully supported roofing products made of steel sheets. No requirements for supporting construction, design of roof system and execution of conn

27、ections and flashings are included. NOTE The European Standard deals partly with flat products, partly with formed (prefabricated) products. Requirements for preformed self-supporting products are given in EN 508-1. 2 Normative references The following documents, in whole or in part, are normatively
