요약

건축물 구획공간에 따른 화재성상 및 열방출율을 측정하기 위하여 실물규모 침대 매트리스의 표준화재시험방법(KS F ISO 12949 : 2011)으로 화재시험을 수행하였다. 개방형공간과 구획공간 모두 버너착화 후 초기 약 3분까지는 유사한 화재성장의 경향을 보이는 것으로 확인되었다. 3분후 구획공간에서의 열방출율이 개방형 공간보다 증가되어 높은 것으로 확인되었다. 침대 매트리스(SS)의 경우, 개방형 공간에서의 최대열방출율은 735 kW이며, 구획공간에서의 최대열방출율은 992 kW 로 측정되었다. 침대 매트리스(Q)의 경우 3분후 구획공간에서의 열방출율이 개방형 공간보다 급격하게 증가되는 것으로 확인되었다. 개방형 공간에서의 최대열방출율은 1,087 kW, 이 때의 측정시간은 346s 이며, 구획공간에서의 최대열방출율은 2,127 kW, 이때의 측정시간은 287 s 측정되어 구획공간에 따른 최대열방출율 및 측정시간의 차이가 확인되었다.

Abstract

To measure the full scale fire test and heat release rate of bed mattresses according to the building compartment space, a fire test was performed using the Standard test method to determine the heat release rate of mattresses and mattress sets (KS F ISO 12949: 2011). Both test locations showed similar fire growth until approximately 3 minutes after burner ignition. After 3 minutes, the heat release rate in the test room was higher than the open calorimeter. For bed mattresses (SS), the maximum heat release rate in the open calorimeter was 735 kW and the maximum heat release rate in the test room was 992 kW. For bed mattresses (Q), the heat release rate in the test room increased more rapidly than the open calorimeter. The maximum heat release rate in the open calorimeter was 1,087 kW (346 s) and the maximum heat release rate in the test room was 2,127 kW (287 s). The difference between the maximum heat release rate and the measurement time according to the test location was confirmed.
