高速铁路动车组二等座座椅的防火标准对比分析及优化座椅的防火性能测试

针对高速铁路动车组二等座座椅中非金属材料的防火测试要求,对比分析了TB/T 3237—2010、DIN 5510-2—2009、BS 6853—1999等相关的常用防火标准与EN 45545-2—2013的异同。基于EN 45545-2—2013对座椅的防火性能进行测试,并提出了优化方案。优化方案不论在非金属材质还是整椅的燃烧性能上都满足EN45545-2—2013对车辆防火最高等级的要求。EN 45545-2—2013对非金属材料的要求更全面,但也存在着不足之处:其在针对座椅非金属材料的防火要求测试与整椅的燃烧测试上并不能完全对应,有待于进一步优化。

Comparative Analysis of Fire Standards and Improvement of Fire Performance Test for High-speed EMU Second Class Seat

According to the fire performance test requirements of nonmetallic materials for the high-speed EMU(electric multiple units)second class seat,the differences between current fire standards of TB/T 3237—2010,DIN 5510-2—2009,BS 6853—1999 and EN 45545-2—2013 are compared and analyzed.Then based on EN 45545-2—2013 standard,the seat fire performance is tested and an optimization scheme is proposed,which can meet the highest requirements of EN 45545-2—2013 standard in terms of non-metallic materials or the whole chair flammability.Though the requirements are more comprehensive,there are still deficiencies in EN 45545-2—2013 standard,the fire resistance test for seat nonmetallic materials and the combustion test of the whole seat are not completely corresponding,therefore the standard needs further optimization.
