Abstract

This paper presents the study of a fire risk to the backside of two miniatures of ISO 9705 2/5 using a lightweight partition for indoor space division and reproduction of the ISO 9705 test. An SGP partition, stud partition, glass wool panel, urethane foam panel, sandwich panel, and glass partition were selected as the test specimens, which are frequently used in construction. According to the ISO 9705 test standard, stabilization was achieved using a measuring device that recorded data before the ignition of a burner and continued recording for 120 s thereafter. After ignition was achieved, the power was increased to 300 kW for 600 s and then reduced to 100 kW for 600 s. The specimens were subsequently observed for 180 s, and the fire risk to the backside and the fire pattern of the wall unit were analyzed. Owing to the amount of heat generated by the ignition source, the maximum temperature of the backside was observed to be 67.7 ℃ for the SGP partition, 55.1 ℃ for the stud partition, 52.4 ℃ for the glass wool panel, 727.4 ℃ for the sandwich panel, 561 ℃ for the urethane foam panel, and 630.5 ℃ for the glass partition. In the cases of the sandwich and urethane foam panels, the explosion of flammable gas occurred by virtue of fusion of the interior materials. The reinforced glass was fractured owing to the temperature difference between the heat- and nonheat-responsive parts. Ultimately, the fire risk to the nearby section room was deemed to be high.

본 논문은 ISO 9705 2/5축소모델 2개를 실내 공간구획에 사용되는 경량칸막이를 이용하여 구획 한 후 ISO 9705 시험을 재현하여 이면부로의 화재위험성에 관한 연구이다. 실험 시료는 시공 시 가장 많이 사용되고 있는 SGP 칸막이, 스터드 칸막이, 그라스울 패널, 우레탄폼 패널, 샌드위치 패널, 유리 칸막이를 선정 하였고, ISO 9705시험 기준에 따라 버너에 점화 전 측정 장치와 데이터의 기록을 시작하여 120 s간 유지시켜 안정화를 취하고, 점화 후 600 s 동안 100 kW, 이후 600 s 동안 300 kW까지 증가하였다가 종료 후 180 s동안 관찰하여 이면부로의 화재 위험성 및 벽체의 화재 패턴을 분석하였다. 점화원에서 발생된 열량으로 인한 최대 이면온도는 SGP 칸막이 67.7 ℃, 스터드 칸막이 55.1 ℃, 그라스울 패널 52.4 ℃, 샌드위치 패널 727.4 ℃, 우레탄폼 패널 561 ℃, 유리 칸막이 630.5 ℃로 측정되었다. 샌드위치 패널과 우레탄폼 패널의 경우 내장재에 용융으로 인한 가연성 가스의 폭발 현상이 발생하였고 강화유리는 수열부와 비수열부의 온도차이로 인하여 유리가 파열되며 인접구획실로의 화재 위험성이 높은 것으로 판단된다.
