DIN EN 508-3:2009-07 EN 508-3:2008 (E) 5 Introduction Figure 1 indicates the position of this standard in the CEN framework of standards concerning
25、roofing products of metal. Roofing products of metal Self-supporting products Fully supported products EN 14782 Copper / Zinc EN 506 Steel 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
26、 calculation and a number of type tests. The performance of a roof constructed with these products depends not only on the properties of 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
27、 of use. DIN EN 508-3:2009-07 EN 508-3:2008 (E) 6 1 Scope This Part of EN 508 specifies requirements for self-supporting roofing products for discontinuous laying made from stainless steel sheet with or without additional metallic and/or organic coatings. The standard establishes general characteris
28、tics, definitions, classifications 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 comply with the requirements or by purchasers to verify that th
29、e products comply before they are despatched from the factory. It specifies the requirements for products which enable them to meet all normal service conditions. The standard applies to all discontinuously laid self-supporting external profiled sheets for roofing with the exception of tiles with a
30、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 transfer any resultant loads and infrequent maintenance loads to the structure. No requirements for supporting construction, design of roof system and e
31、xecution of connections and flashings are included. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including
32、 any amendments) applies.

34、e following terms and definitions apply. 3.1 General 3.1.1 self-supporting product Product which will, by virtue of its material and shape, support all applied loadings (e.g. snow, wind, foot traffic) and transmit these loadings to spaced structural supports. 3.2 Materials 3.2.1 stainless steel stee
35、l sheets with at least a content of 10,5 % chromium and max 1,2 % carbon NOTE For roofing products the stainless steel grades are: DIN EN 508-3:2009-07 EN 508-3:2008 (E) 7 ferritic; austenitic with or without molybdenum; austenitic ferritic (duplex); and higher alloyed grades. 3.2.2 terne coated sta
