Consisting of organic compounds, plastic ignites easily and burns fast. In addition, a large amount of toxic gas is produced while it is burning. When plastic is heated, its volume decreases because its surface is melted. The decomposition of its molecular bond generates combustible liquid of low viscosity, which accelerates plastic combustion and spreads the flames. Radiant heat produced in the process propagates the fire to increase the risk of human and property damages. In Korea, plastics used as interior cladding materials are rated as noncombustible, semi noncombustible or flame-retarding. Since KS F ISO 5660-1 (cone calorimeter) which determines whether the materials are flame-retarding or not is based on heat release rate only, it is not dependable enough to judge their fire propagation characteristics. In this study, tests to identify the chemical and thermal characteristics, flammability characteristics and fire propagation characteristics of plastics were conducted using a fire propagation apparatus (FPA) provided in ISO 12136 and ASTM E 2058.
