In normal building fires, the main risk of combustion expansion is not only the combustibles materials in a building but also the risk to the spread of surface combustion of the interior finishing materials. Therefore, it is important to regulate the methods and standards for testing the performance of flame retardant in fire law and building ordinances. In this study, the fire characteristics of interior finishing materials are analyzed through the cone-calorimeter test, the flame retardant performance test and the VSR measuring test of building material. First, the results of the cone-calorimeter test confirmed that the ignition and flame combustion were started as soon as the radiant heat shield was removed, which could be a rapid propagation factor of the flame in the event of fire. Second, the results of the VSR measuring test showed that harmful gases for human body were released from the interior finishing materials. As observed from the result of examination, the interior finishing materials(five species including form blocks) should be used not only in the multi-use facilities occupied by unspecified majority but also in residences because of the sudden increase of the combustion in case of fire. Hence, it is urgent to limit the combustion characteristics of materials based on the use of interior finishing materials, the maximum thermal discharge rate and the emission of harmful gases.
