21、 and the United Kingdom. BS EN 506:2008EN 506:2008 (E) 5 Introduction Figure 1 indicates the position of this standard in the CEN framework of standards concerning roofing products of metal. Roofing products of metal Self-supporting products Fully supported products EN 14782 Copper / Zinc EN 506 Ste
22、el EN 508-1 Aluminium EN 508-2 Stainless steel EN 508-3 Figure 1 Framework of standards 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
23、 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. BS EN 506:2008EN 506:2008 (E) 6 1 Scope This European Standard specifies requirements for self-supporting roofing products for
24、discontinuous laying made from copper or zinc-copper-titanium alloy sheet with or without additional organic coatings. The standard establishes general characteristics, definitions and labelling for the products, together with requirements for the materials from which the products can be manufacture
25、d. 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 con
26、ditions. The standard applies to all discontinuously laid self-supporting external profiled sheets for roofing with the exception of tiles with a surface area less than 1 m2and produced by stamping. These profiled roof sheets are designed to keep wind, rain and snow out of the building and to transf
27、er 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. 2 Normative references The following referenced documents are indispensable for the application of thi
28、s document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
