BS EN 16704-2-2:2016规定了障碍物的要求，以便用户能够防止 工人不得使用此类屏障无意中进入危险区。本标准规定了这些障碍物的最低要求和测试程序 尺寸、稳定性和电气性能。本标准还提供了有关人员所在位置的标记（视觉分界线）的建议 就会进入危险区。有关屏障和TW的组合，另见EN 16704-2-1:2016。本标准包含对第三轨道系统电气危害的参考。注:城市轨道系统也有相同的情况，但可能有其他单独的轨距。EN 16704-1不包括城市轨道系统。使用屏障作为安全措施具有相同的目的 那种铁路系统。本标准特别不涉及:工作期间轨道安全防护的风险评估； 作业期间轨道安全防护的安全措施等级；在工地区域提供安全工作和安全列车运行的安全措施；在轨道上规划和操作障碍物的国家安全法规；安全法规和附加要求，例如，由于国家或操作规则或 用户与制造商之间的协商；不同带电电路的不同电位引起的电气危害。交叉引用:EN 364:1992EN 1263-1EN 12811-2EN 12811-3:2002EN 13374:2013EN 14067-4EN 50110-1EN 50110-2EN 50122-1EN 50122-2EN 50122-3EN 50125-3:2003EN ISO 13857ISO 13857EN 16704-1:2016EN 16704-3:2016EN 15273-3购买本文件时可用的所有现行修订均包括在购买本文件中。

BS EN 16704-2-2:2016 deals with requirements for barriers to give users the possibility to prevent workers from entering the danger zone unintentionally by the use of such barriers.This standard defines minimum requirements and test procedures for these barriers concerning the dimensions, the stability and electrical properties.This standard also gives recommendations for the marking (visual demarcation line) where a person would enter the danger zone.For combinations of barriers and TWS see also EN 16704-2-1:2016.This standard contains references to electrical hazards from third rail systems.NOTE Urban rail systems do have the same situations but may have other individual track gauges. EN 16704-1 does not cover Urban rail systems. The use of barriers as a safety measure has the same intention independently of the kind of railway system.This standard in particular does not deal with:risk assessment for safety protection on the track during work;hierarchy of safety measure for safety protection on the track during work;safety measure to provide safe working and safe train operation in the area of a work site;national safety regulations to plan and operate barriers in track;safety regulations and additional requirements e.g. due to national or operational rules or negotiation between the user and the manufacturer;electrical hazards by different potential of different electrified circuits.Cross References:EN 364:1992EN 1263-1EN 12811-2EN 12811-3:2002EN 13374:2013EN 14067-4EN 50110-1EN 50110-2EN 50122-1EN 50122-2EN 50122-3EN 50125-3:2003EN ISO 13857ISO 13857EN 16704-1:2016EN 16704-2-1:2016EN 16704-3:2016EN 15273-3All current amendments available at time of purchase are included with the purchase of this document.
