Discussion on Flame Retardant Test Method of Interior Materials and Components for Railway Vehicle
Based on the main flame retardant standards of interior materials and components for rail vehicles at home and abroad and the cited method standards,the differences of eight test methods,including ignitability,flammability,heat release,flame propagation,smoke generation,smoke toxicity,fire partition and overall seat fire protection,are compared and discussed from the aspects of equipment,combustion mode,specimen requirements,specimen placement and result expression.The content of flame retardant standards in various countries is similar,but there are significant differences in equipment,focus and testing methods.The EN 45545 standard has detailed classification and comprehen-sive test methods.The experience of this standard can be used for reference in China to develop new fire protection stand-ards,which is conducive to the management of railway vehicle fire safety in China.
