本文件规定了为减少PTW乘客在从PTW车辆上跌落后沿地面滑动时碰撞安全栅而设计的系统的碰撞性能要求。相关保护系统是安装在障碍物上的系统，或具有PTW驾驶员固有保护或降低风险能力的障碍物。本文件不包括对障碍物的车辆约束能力及其对碰撞车辆乘员的风险的评估。EN 1317-1和EN 1317-2涵盖了碰撞车辆的屏障性能评估。 本文件定义了性能等级，其中考虑了骑手速度等级、影响严重性和 与骑手碰撞有关的系统工作宽度。 对于设计用于添加到标准屏障的系统，只有当系统 适用于试验中使用的屏障模型，因为如果 该系统安装在不同的屏障上。交叉引用:EN 1621-1ISO 6487EN 1317-2UNE 135900-2UNE 135900-1EN 1317-1EN 1317-7SAE J1733SAE J1727SAE J211-1EN 1317-3ISO 13232（所有零件）EN ISO 4762EN 1317-5购买本文件时可提供的所有现行修订件均包含在购买本文件中。

This document specifies requirements for the impact performance of systems designed for the reduction of impact severity for PTW riders impacting safety barriers whilst sliding along the ground, having fallen from their PTW vehicle. The protection systems concerned are those fitted to barriers or barriers that have an inherent PTW rider protection or risk reduction capability. This document excludes the assessment of the vehicle restraint capabilities of barriers and the risk that they represent to the occupants of impacting cars. The assessment of barrier performance with respect to impacting vehicles is covered by EN 1317-1 and EN 1317-2. This document defines performance classes taking into account rider speed classes, impact severity and the working width of the system with respect to rider impacts. For systems designed to be added to a standard barrier, the test results are valid only when the system is fitted to the model of barrier used in the tests since the performance will not necessarily be the same if the system is fitted to a different barrier.Cross References:EN 1621-1ISO 6487EN 1317-2UNE 135900-2UNE 135900-1EN 1317-1EN 1317-7SAE J1733SAE J1727SAE J211-1EN 1317-3ISO 13232 (all parts)EN ISO 4762EN 1317-5All current amendments available at time of purchase are included with the purchase of this document.
