BS EN 13848-5:2017规定了轨道几何质量等级的最低要求， 并规定了EN 13848-1中定义的每个参数的安全相关限值，由 EN 13848-2、EN 13848-3和EN 13848-4中定义的任何轨道几何测量系统。本欧洲标准涵盖以下主题:立即行动限制（IAL）；关于隔离缺陷公差水平的建议；参数相对于车辆行为的相对重要性。测量的必要性、测量频率和测量参数的选择 不在本欧洲标准范围内。本欧洲标准适用于高速和常规线路，包括道岔和交叉口， 如果在这些线路上运行的车辆符合 EN 14363和其他车辆安全标准。本欧洲标准不适用于城市铁路系统。 交叉引用:EN 14363:2016BS EN 14363:2016EN 13803:2017ORE B 55EN 13848-6:2014EN 13848-3:2009EN 13848-2:2006EN 13848-4:2011CEN/TR 16978:2016EN 13231-1:2013购买本文件时可提供的所有当前修改件均包含在购买本文件中。

BS EN 13848-5:2017 defines the minimum requirements for the quality levels of track geometry, and specifies the safety related limits for each parameter as defined in EN 13848-1 and measured by any track geometry measurement system as defined in EN 13848-2, EN 13848-3 and EN 13848-4.This European Standard covers the following topics:immediate action limits (IAL);recommendations on tolerance levels for isolated defects;relative importance of parameters with respect to the vehicle behaviours.The necessity to measure, the frequency of measurements and the selection of measured parameters are not covered by this European Standard.This European Standard applies to high-speed and conventional lines, including switches and crossings, of 1 435 mm and wider gauge railways provided that the vehicles operated on those lines comply with EN 14363 and other vehicle safety standards.This European Standard does not apply to Urban Rail Systems.Cross References:EN 14363:2016BS EN 14363:2016EN 13803:2017ORE B 55EN 13848-6:2014EN 13848-3:2009EN 13848-2:2006EN 13848-4:2011CEN/TR 16978:2016EN 13231-1:2013All current amendments available at time of purchase are included with the purchase of this document.
