Fire Containment
ASTM E2307 measures the ability of perimeter fire barrier systems to maintain a seal and prevent interior fire spread as the exterior wall assembly deflects and deforms during fire exposure. The ASTM E2307 test exposes the joint to fire from the room of fire origin and the exterior wall to fire from both the interior and the exterior as the fire plume exits the room of fire origin through a window opening. ASTM E 2307 determines the period of time that the perimeter fire containment system will limit flame penetration through the opening between the exterior wall assembly and the floor assembly.
