The performance of a roof constructed with these products depends not

27、 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 of use.

28、 EN 508-3:2008EN 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 characteristics, definition

29、s, 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 the products compl

30、y 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 surface area les

31、s 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 execution of conn

32、ections 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 any amendments)
