Abstract

This European Standard specifies three methods for determining the performance of roofs to external fire exposure. The three methods assess the performance of roofs under the following conditions:test 1 - with burning brandstest 2 - with burning brands and windtest 3 - with burning brands, wind and supplementary radiant heat.The tests assess the fire spread across the external surface of the roof, the fire spread within the roof, the fire penetration (tests 1 and 3) and the production of flaming droplets or debris falling from the underside of the roof or from the exposed surface (tests 1 and 3).Tests 2 and 3 are not applicable to geometrically irregular roofs or roof mounted appliances e.g. ventilators and roof lights.NOTE The three tests listed above do not imply any ranking order. Each test stands on its own without the possibility to substitute or exchange one for another.
