요약
본 연구에서는 그라스울 샌드위치패널의 연소특성을 판단하기 위하여 밀도와 두께가 다른 총 6종류(밀도: 48/64 K, 두께: 50/75/100 T)의 시편을 선정하여, KS F ISO 9705 시험법을 준용하여 실물화재 시험을 실시하였다. 실물화재 시험은 $2.4(L){ imes}3.6(W){ imes}2.4(H)m$ 크기의 화재실 내부에 시험체를 설치하여 프로판 버너에 의해 시편을 화염에 노출시켜 연소특성을 판단하게 된다. 총 25분에 시험 시간 동안 프로판 버너는 100 kW(10분), 300 kW(10분)로 출력되며, 시험을 통해 열방출률, 열류량, 내부 온도가 측정된다. 실물화재 시험을 실시한 결과, 버너 열량을 포함하여 각 시편의 최대 열방출률은 333.2~365.5 kW, 최대 열류량은 12.4~12.9 kW/$m^2$로 나타났으며, 최대 내부온도는 모든 시편에서 $500^{circ}C$를 초과하지 않았다. 실물화재 시험 중에 플래시오버 현상은 발생하지 않았으며, 각 시편의 열방출률, 열류량, 내부 온도 측정결과 시편의 밀도 및 두께에 따른 차이점은 나타나지 않았다.
Abstract
A real A real scale fire test was performed in accordance with KS F ISO 9705 test method to investigate the combustion characteristics of glass wool sandwich panels. To do this, six kinds of specimens having different density and thickness were examined. The glass sandwich panels were installed inside the room, which had internal dimensions of 2.4 m wide${ imes}3.6m$ deep${ imes}2.4m$ high. also, combustion characteristic are determined through the exposure of specimens to flame by the propane gas burner has a capacity of 100 kW (10 minutes) and 300 kW (10 minutes) for total 25 minutes of test time. Results of the real sale fire test, it was found that maximum HRR of each specimen was 333.2~365.5 kW, maximum heat flux was 12.4~12.9 kW/$m^2$ And, maximum internal temperature for all specimens was not over $500^{circ}C$. During the real scale fire test, flash-over didn't occur and the difference by density and thickness of specimen was not found from the results of HRR, heat flux, and internal temperature measurement.
