철도차량용 재료의 독성성분 정량화 향상기법 연구

초록

This study is on the fire resistance evaluation method, expecially on the toxicity of smoke gases generated from the fire, of materials for railway car and structures. Until now, Although international standard related to the quantifying evaluation method of smoke gas is provided but the specific procedure is not contained. On this reason, Test results of toxicity show deviation with the different technique being applied. For now, In advanced railway country, various instrument, like ion chromatography and etc., is used but FT-IR is recommended due to its lots of advantages. while FT-IR has a lot of strong points but still has some problems like water vapor interferences. In this paper, To improve credibility and repeatability of FT-IR it contains some technical solutions in quantifying the 8 toxic components.
