| 摘要： | All vehicle restraint devices on European roads are - or should be - certified according to the European impact standard EN 1317, implying conformity. But it doesn't necessarily ensure that the crash barrier will perform its main aim of saving the vehicle occupants' lives. This is especially the case for frontal barriers, such as crash cushions and end terminals. The so-called capacitive test for crash cushions performed by using the heaviest vehicles is a frontal test at 110kph using a 1,500kg vehicle. The impact of this one-and-a-half-tonne vehicle with the obstacle generates around 701 kJ of kinetic energy. |
