24、N 508-2:2008 (E) 5 Introduction Figure 1 indicates the position of this standard in the CEN framework of standards concerning roofing products of metal.

25、ss 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 the product as required by this stand
26、ard, but also on the design, construction and performance of the roof as a whole in relation to the environment and conditions of use. DIN EN 508-2:2009-07 EN 508-2:2008 (E) 6 1 Scope This part of EN 508 specifies requirements for self-supporting roofing products for discontinuous laying made from a
27、luminium sheet with or without additional organic coatings. The standard establishes general characteristics, 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 man
28、ufacturers 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. The standard applies to all disco
29、ntinuously laid self-supporting external profiled sheets for roofing. 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
30、 roof system and execution of connections and flashings are included. 2 Normative references The following referenced documents are indispensable for the application of this document.
