Abstract

Interior finishing materials using noncombustible were regulated by the building codes to prevent the spread of fire and protect occupants. The average deed of stopping time of experimental mouse exposing combustion gas were measured by KS F 2271 gas toxicity test. At that time, The average deed of stopping time under 9 minutes were judged a inconsistence. This experiment method has limit to find out a cause of toxicity effect factor. In this study, particle size analysis were performed for investigate a major factor.

현행 건축법은 건축물의 규모, 용도에 따라 화재확산방지와 재실자의 보호를 위하여 실내 마감 재료를 불연, 준불연, 난연재료로 시공하도록 규정하고 있으며, 가스 유해성 시험(KS F 2271)에 따라 해당 시료의 연소 생성물에 노출된 실험용 쥐의 평균행동정지시간을 측정하여 연소 생성물의 유해성을 평가하고 있다. 실험용 쥐를 대상으로 가스상, 입자상 물질의 복합적 유해효과를 분석한 결과인 평균행동정지시간이 15분의 노출 시험 중 9분 이내로 측정된 경우, 연소 유해성 평가 결과가 부적합한 것으로 판정한다. 이에 본 연구에서는 연소 생성물에 포함된 가스상, 입자상 물질 중에서 실험용 쥐의 행동정지에 미치는 영향이 큰 요소를 규명하기 위하여 연소 생성물에 포함된 입자상 물질의 입도 분석을 실시하여 위험도의 상관관계를 밝혔다.
