Abstract

A room scale fire test was done for interior materials from a subway vehicle installed within an ISO 9705 fire test room. The interior materials are the old ones which were made before the new fire safety guideline of subway vehicles. The output of ignition burner was increased in controlled steps to CEN/TS 45545-1. The objectives of this interior fire test are to assess the fire performance in terms of ignition and flame spread on interior lining materials and to provide data on an enclosure fires involving subway vehicle interior materials that grow to flashover. Temperatures, heat flux and heat release rate variations verse time of the test are measured. Heat release rate is compared with that of calculated by modified flaming area based summation method. These test results will be used for verification of CFD fire simulation of full subway vehicle.

구형 지하철 전동차의 내장재에 대하여 ISO 9705 시험 설비를 이용하여 화재시험을 수행하였다. 시험에 사용된 점화용 버너는 CEN/TS 45545-1 규정에 따라 출력을 조정하였다. 이 내장재 화재시험의 목적은 화원의 규모에 따라서 철도차량에서의 화재거동과 화염의 전파 경로를 평가함과 동시에 객실 내장재의 화재가 플래시오버로 진행하는 경로의 화재 데이터를 제공하는 것이다. 시험으로부터 시간에 따른 위치 별 온도 값과 열류량 및 열방출률을 측정하였고 열방출률은 수정된 화염면적기반 합량법으로 계산한 결과와 비교하였다. 이 시험 결과는 CFD 화재 시뮬레이션 기법을 이용한 철도차량 화재해석의 검증 데이터로 활용될 수 있을 것이다.
