AbstractThe purpose of this apparatus is to measure the linear flame penetration along the length of seams in a floor assembly. This is used to indicate when the floor system has failed and to determine the time of floor failure in the fire tests conducted in the Fire Performance of Houses test facility. The principal of operation is the electrical conductivity present in open flames due to the ionization of the fire gases. A conductor wire is stapled to the joint in the floor seam and a porous metal screen is positioned over the conductor wire. When flame penetrates through the floor seam electron current flows between the two conductors and the amount of current flow is directly proportional to the length of flame passing through the seam.
