Comparative study on the Limited Oxygen Index of the gangway materials of the railroad vehicles

철도차량용 통로 연결막의 재질별 산소지수 비교연구

According to ISO 4589-2:2001, we studied on the fire characteristics of some gangway materials used as the interior materials of the railroad vehicles. Currently materials of the gangway used in the railroad vehicles tend to alternate PVC coated fabric mostly used in former days with synthetic rubber or silicone. Accordingly, we compared Limited Oxygen Index on them in this study. And we found that the test results of the synthetic rubber or silicone gangway are better than those of the PVC coated fabric gangway largely.
