요약
ISO 9705 room-corner test 기준에 따른 가연성 내장재의 화재위험성 평가를 위해 개발된 Quintiere 모델의 검증을 위해 이태리 L. S. F의 실대 화재 실험 결과와 비교 분석하였다. ISO 9705 시험은 최초 10분간은 100 kW, 이후 10분간은 300 kW의 화원에 노출된 벽, 천장재의 화염확산 성능 평가방법으로 열 방출비율이 1 MW에 이르면 플레쉬오버가 발생한다고 판단한다. 총 13개의 재료 중 실제 화재 시 용융, 박락, 변형 등이 나타나는 경우는 단위 면적 당 발생 열량 수정 값을 적용하였다. 바탕 면에 계속 부착되어 있는 마감재의 예측결과는 실험 결과에 근접하였다. 또한 Large-scale Test의 실험결과와 모델의 예측성능도 비교 분석하였다.
Abstract
New examination of a predictive model for the ISO 9705 room-corner test have been m made for materials studied by L S Fire Laboratories, Italy. The ISO 9705 test subjects wall a and ceiling mounted materials to a comer ignition source of 100 kW for a duration of 10 m minutes; if flashover does not occur this is followed by 300 kW for another 10 minutes. The m materials that did not stay in place during combustion because of melting, dripping, or d distorting were simulated by an adjustment to the material's total available energy. For m mat려als that remain in place the simulation model appears to do well in its prl어ictions. A l large-s떠Ie room test results 뾰 compar벼 with the m여el’s prediction also.
