用在火车上的弹性体，如橡胶密封圈，不但要达到防火的标准要求，其机械性能也应达到相应要求。
德国标准DIN 5514弹性体机械性能测试需根据以下标准进行测试：
◆DIN
铁道机车用的材料;弹性体,概念,材料的数据
Materials for railway vehicles; elastomers, terms , material indication
◆DIN
铁路机车用材料;弹性体;检验
Materials for railway vehicles; elastomers, testing
◆DIN
铁道机车用的材料;弹性体,功能组;永久性密封的门、窗型材,要求类别
Materials for railway vehicles; elastomers, functional group: permanent door and window seals, specification group
◆DIN
铁道机车用的材料;弹性体,功能组;非永久性密封的门、窗型材,要求类别
Materials for railway vehicles; elastomers; functional group: non permanent door and window seals; specification groups
◆DIN
有轨车辆用材料.弹性体.车身用型材.要求类别
Materials for rail vehicles; elastomers; function group: profiles for the vehicle superstructures; specification groups
◆DIN
铁路车辆用材料.弹性体.功能组.第6部分:制动零件、规范分组
Materials for railway vehicles; elastomerers; functional group: brakeparts, specification groups
德国标准DIN 5514弹性体（橡胶密封条）的机械性能测试包含以下内容：
•Hardness /硬度
•Tensile properties /抗拉强度
•Compression set /压缩强度
•Low-temperature performance /低温性能
•Ageing test /老化测试
•Ozon test /臭氧测试
•Resistance against cleaning agents /抗清洁剂测试
•等等
