A comparative study on the interior materials of the railroad vehicles by the test of Oxygen Index and Fire Spread

In this study, we compared Oxygen Index by ISO 4589-2 with Fire Spread by ISO 5658-2. The result shows that the tset values of Fire Spread such as IT, CFE, Qsb have mutual relations with thoses of Oxygen Index values in some samples. And we found that the tset values of Fire Spread make up for the insufficient points of Oxygen Index has its limits to evaluate the properties of fire for the interior materials of the railroad vehicles.
