Large-scale fire tests are sometimes necessary to assess the validity of fire safety proposals that would restrict the use of wood products in buildings. Simulated dwelling burns in 1967 and mobile home burns in 1976 were sponsored by the Hardwood Plywood Manufacturers Association. In both series of burns, the performance of Class A and Class C flamespread wall interior finish was compared. Early limiting occupant egress conditions appeared to be primarily influenced by the combustible contents typical of and contained within the test structures.
