BS EN 508-3 is the third part of multiple series that specifies requirements for self-supporting products for roof covering, wall cladding, lining, liner tray and tile products for discontinuous laying made from stainless steel sheets with or without additional metallic and/or organic coatings. Sheets intended to be used with insulation and membranes are also covered.
BS EN 508-3 applies to all discontinuously laid self-supporting external profiled sheets for the roof covering, wall cladding, lining, liner trays and tile products apart from tiles with a surface area less than 1 m2 and 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.
NOTE-
BS EN 508-3 does not cover products for structural purposes, i.e., it does cover products used in structural class III (according to EN 1993-1-3), does not cover products used in constructions of structural classes I and II (according to EN 1993-1-3) intended to contribute to the global or partial stability of the building structure by providing racking resistance or resistance to permanent static loads (excluding self-weight of the metal sheet).
No requirements for supporting construction, design of roof or cladding, lining, tile system and execution of connections and flashings are included.

Why should you use BS EN 508-3?
Stainless steel is the best choice for fire safety and prevention. It cannot catch fire easily as it has a high resistance to corrosion. Low alloyed grades resist corrosion in atmospheric conditions whereas highly alloyed grades can resist corrosion in most acids, alkaline solutions, and chloride bearing environments, even at elevated temperatures and pressures.
BS EN 508-3 establishes general characteristics, definitions, classifications and labelling for the products, together with requirements for the materials from which the products can be manufactured. If you are a manufacturer, it helps you to comply with the requirements or if you are a purchaser, it helps you to verify that the products comply when purchased before, they are dispatched from the factory. It specifies the requirements for products that enable you to meet all normal service conditions.
Consequently, if you are planning for a fire-resistant project, BS EN 508-3 helps you with the specifications and test methods for self-supporting products for roof covering, wall cladding, lining, liner tray and tile products for discontinuous laying made from stainless steel sheets with or without additional metallic and/or organic coatings where fire prevention and safety is essential.
