This study investigated the combustion properties of hard wood 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 equations. The external heat flux was maintained at 50 kW/m2. Hard wood used Paulownia, Ash, Maple. Smoke performance index-V (SPI-V) of the specimens were increased by 5.6 to 6.3 times compared with Paulownia. The smoke risk due to smoke performance index-V increased in the order of Maple < Ash < PMMA < Paulownia. The smoke growth index-V increased from 1.4 to 7.2 times compared with Maple. The smoke risk due to smoke growth index-V increased in the order of PMMA < Maple < Ash < Paulownia. Smoke risk index-VI by smoke rating index increased in order of PMMA, Maple < Ash < Paulownia. According to comprehensive assessment of smoke risk properties, Maple showed lowest smoke risk materials among the woods. |
