EN45545标准规定的防火措施和要求的目的是一旦车辆着火保护乘客和铁路车辆工作人员免受损害。轨道车辆材料供应商都想豁免EN45545测试。EN45545-2标准中对于豁免的条件也做了明确规定。
EN45545-2标准为EN45545-2:2013+A1:2015，EN45545-2标准对于豁免的条件也做了明确规定。此原则适用于所有产品：
1. Products which comply with the highest level of reactive tofire performance and therefore need no further testing are
-products classified as A1 according to EN 13501-1
-all products described in commission decision 96/603/EC (asamended)
2. Products classified as A2-s1,d0 according to EN 13501-1 areconsidered compliant with regard to flame spread, heat release andsmoke emission requirement only. The toxic emissions limit shallsatisty the requirements of R1 HL3 (CIT＜0.75）
