This study investigated the combustion properties of wood specimens for the constructional interiors, especially focusing on smoke risk properties in fire scenarios. Smoke risk properties were measured by using a cone calorimeter (ISO 5660-1) and analyzed using Chung’s equation-V, -VI. The external heat flux was maintained at 35 kW/m2. Smoke performance index-V (SPI-V) of the specimens were increased by 2.6 to 3.7 times compared with Japanese cedar. The smoke growth index-V increased from 1.2 to 3.5 times compared with Red pine. Smoke risk index-VI by smoke rating index increased in order of Spruce, Red pine < PMMA, Lauan < Japanese cedar. According to comprehensive assessment of smoke risk properties, Spruce, Red pine showed lowest smoke risk materials among the woods. |
