The buildings perimeter fire containment system is a unique building construction detail not addressed by other fire test methods. This test method is intended to simulate a post flashover fire exposure within a compartment venting to the exterior of the building and causing fire to spread to the floor above through or around the building perimeter containment system via the exterior of the building. This standard evaluates the fire performance of a perimeter wall assembly, including the interface between the perimeter joint system and the interior surface of the exterior wall and the vision glass, in terms of its ability to prevent the external spread of fire to the room above due to flame or heat transfer. Among its other functions, a building perimeter containment system impedes the vertical spread of fire from the floor of origin to the floor(s) above, at the buildings exterior perimeter and accommodates various movements such as those induced by thermal differentials, seismicity, and wind loads.
