External exposure of roofs to fire — Part 1: Test method

ISO 12468-1:2003 specifies a test method to determine the resistance of roofs to external fire exposure. This method evaluates the behaviour of the roof when exposed to two types of burning brands combined with wind and with or without heat radiation, concerning the fire spread across the external surface of the roof, the fire spread within the roof, the fire penetration and the production of flaming droplets or debris falling through the roof, from the underside of the roof or from the exposed surface.
