BS EN 508-2 specifies requirements for self supporting roofing products for discontinuous laying made from aluminium 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 manufacturers 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.
BS EN 508-2 applies to all discontinuously 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 roof system and execution of connections and flashings are included.
