    Durable Fire Testing Equipment ENV 1187 Test 2 Roof Testing With Burning Brands / Wind

    ENV 1187 Test 2 Roofing Test with Burning Brands and Wind, Fire Testing Equipment


    Description:


    This European Specification specifies four methods for determining the performance of roofs to external fire exposure. The four methods assess the performance of roofs under the following conditions:

    Test 1 - with burning brands

    Test 2 - with burning brands and wind

    Test 3 - with burning brands, wind and supplementary radiant heat

    Test 4 – with two stages incorporating 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 (Tests 1, 2 and 3), the fire penetration (Tests 1, 3 and 4) and the production of flaming droplets or debris falling from the underside of the roof or from the exposed surface (Tests 1, 3 and 4). Tests 2 and 3 are not applicable to geometrically irregular roofs or roof mounted appliances e.g. ventilators and roof lights.

    The four 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.
