This European Standard shall be given the status of a nati

19、onal standard, either by publication of an identical text or by endorsement, at the latest by January 2009, and conflicting national standards shall be withdrawn at the latest by January 2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of pate

23、osition 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 Steel EN 508-1 Aluminium EN 508-2 Stainless steel EN 508-3 Figure 1 Framework of standards In thi

24、s 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 standard, but also on the design, construction and performanc

25、e of the roof as a whole in relation to the environment and conditions of use. BS EN 508-2:2008EN 508-2:2008 (E) 6 1 Scope This part of EN 508 specifies requirements for self-supporting roofing products for discontinuous laying made from aluminium sheet with or without additional organic coatings. T

26、he 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 manufacturers to ensure that their products comply with the requ

27、irements 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 discontinuously laid self-supporting external profiled sheets for

28、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 roof system and execution of connections and flashings are i
