BS EN 507:2019 pdf free.Roofing and cladding products from metal sheet – Specification for fully supported products of aluminium sheet.
BS EN 507 The recommended minimum nominal thickness (excluding thickness of organic coatings), if not calculated or tested under service conditions, such as wind, snow and maintenance loads, and the product processing conditions, for trays, panels, or tiles for fully supported applications shall be 0,6 mm.
Depending on dimensional requirements for fixing and fabrication, manufactunng tolerances for the formed product shall be agreed at the time of ordering.
NOTE Some of the preformed products are fully defined and designed by a code of practice”. Other products need a verification of the capacity to take wind load. This can be done by either testing or calculation, see EN 508-
Safety in case of fire
Aluminium is non-combustible. It will not burn and will not support combustion. Its melting point is 570 °C up to 660 °C. As a result it will melt in an intense fire. It is essential that the effect of a fire is evaluated after studying the whole structure.
The packaging requirements and any special ordering conditions requirements to take account of particular conditions shall be agreed between manufacturer and purchaser at the time of ordering.
Transport, storage and handling
Any instructions regarding transport, handling or storage shall be clearly visible on the package.
The packages should be fully supported by means of battens or pallets providing sufficient space to permit good ventilation while avoiding any permanent deformations of the products. The packages should be inclined in order to promote drainage.
The packages should be stored under a covered warehouse or under a cover made from tarpaulin over a frame. The frame should allow sufficient space between tarpaulin and packages to allow air to circulate.
NOTE Moisture, in particular condensation inside packages, can lead to the formation of stains (e.g. black marks), and if there is prolonged contact with moisture, can cause aesthetic damage.
During transportation, dark spots can appear on light surfaces as a result of friction in contact with uncoated aluminium when packing allows movement between neighbouring surfaces.
If severe service conditions are expected during transportation, storage or processing, the product can be supplied with an additional protection of a temporary, strippable film, wax or oil, by agreement.
Type, thickness, adhesion properties, formability, tear strength and light fastness should be taken into consideration when choosing protective films.
All protective films can only be exposed to outdoor weathering for a limited period without deterioration. This depends on product specification that are provided by the protective film supplier.BS EN 507 pdf download.
