23、 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 constructed with these products depends not only on the properties of the product as it is required by this standard, but also on
24、the design, construction and performance of the roof in relation to the environment and conditions of use. DIN EN 502:2013-06 EN 502:2013 (E) 5 1 Scope This European Standard specifies requirements for roofing products used for assembly into coverings for pitched roofs, made from stainless steel, te
25、rne coated, tin coated or organic coated stainless steel sheet. 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 manufac
26、turers 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 conditions. Products can be prefabricated or semi
27、formed products as well as strip, coil and sheet for on-site-formed applications (e.g. standing seam roofs, roll cap). The European Standard applies to all discontinuously laid and fully supported roofing products made of stainless steel sheet. No requirements for application (e.g. methods of fixing
28、, supporting construction, design of roof system, 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 roofing products are given in EN 508-3. 2 Normative refer
