基于欧盟标准的车辆材料防火指标分析

Analysis of Fire Protection Index of Vehicle Materials Based on EU Standard

介绍了欧盟EN 45545标准实施背景。基于火焰蔓延、点燃性、热释放速率、烟密度及烟毒性等五项材料防火性能指标,对EN 45545-2:2013、DIN 5510-2:2009及BS 6853:1999中的材料测试标准进行了对比分析,以了解DIN 5510-2:2009、BS 6853:1999与EN 45545-2:2013中材料防火性能水平差异,为轨道交通车辆材料防火优化提供了设计依据。

The background information to implement EN 45545 standard in EU is briefly introduced.Based on five material fire protection indexes,as in flame spread,flammability,heat release rate,smoke density and smoke toxicity,the material test standards in EN 45545-2:2013,DIN 5510-2:2009 and BS 6853:1999 standards are compared and analyzed.The differences of expected fire protection performance in EN 45545-2:2013,DIN 5510-2:2009 and BS 6853:1999 standards are introduced to provide a design reference for rail transit vehicle fire protection improvement.
