RESIDENTIAL UPHOLSTERED FURNITURE IN THE UNITED STATES AND FIRE HAZARD

摘要

Full scale fire tests were performed on three items of upholstered furniture used in US residential applications. The items were virtually identical, except that two of them contained foam padding that complied with the California TB 117 requirements and one did not. In all three cases, the furniture was easily ignited by the effect of a small open flame in the middle of the seat and released heat sufficiently fast (well over 2 MW) to cause flashover in the fire test room. The major fire performance difference between the CA TB 117 foam products and the standard foam product was the fact that a slightly more intense igniting flame was needed for the former. For comparison purposes, an alternative commercial item of upholstered furniture, which used well fire-retarded foam, was also tested; it easily resisted ignition by small open flames.
