      Examination of the Thermal Conditions of a Wood Floor Assembly above a Compartment Fire
      
            Test 1 (2:31) No audio.The floor system installed for this experiment was laminate flooring over OSB with composite wood I-joists spaced 24 inches apart. Video views from top left: Side A, BST thermal imager showing upper level floor, aSi thermal imager showing upper level floor, Clock, video showing upper level floor, VOx thermal imager showing upper level floor, CD corner, thermal imager view of lower level interior, video view of lower level interior.Ignition starts at 0 seconds. The first gypsum board is removed at 10 minutes, 10 seconds. The second gypsum board is removed from the doorway at 15 minutes, 35 seconds. Flashover occurs in the lower level at 17 minutes, 45 seconds. Flames come out of the lower level door at 18 minutes, 5 seconds. Thermal imagers are removed at 23 minutes, 25 seconds. The floor collapses at 24 minutes and 30 seconds. Extinguishment begins at 24 minutes, 50 seconds.
