本欧洲标准提供了一个系统，用于识别和呈现关于ILU的信息。识别系统旨在用于一般应用，例如在文档，控制和通信（包括自动数据处理系统）中，以及用于在ILU和其他非ISO容器上显示（即哪些尺寸和测试参数与由适用的ISO标准）用于欧洲运输。 包括通过永久标记在ILU上显示识别和特定其他数据（包括操作数据）的方法。 本欧洲标准规定: a）具有用于验证其使用准确性的相关系统的ILU识别系统，具有用于呈现用于视觉解释的识别系统的强制性标记，以及 b）用于ILU大小数据的编码系统，其显示对应的标记; c）强制性操作标记; d）在ILU上物理呈现标记。 欧洲标准的这一部分规定了半挂车编纂业务数据系统。编码为轨道上可用的覆盖区域分配给半拖车，以便能够选择这些轨道

This European Standard provides a system for the identification and presentation of information about the ILU. The identification system is intended for general application, for example in documentation, control and communication (including automatic data processing systems), as well as for display on the ILU and other non ISO containers (i.e. which dimensions and testing parameters differ from those defined by the applicable ISO standards) used in European transport. The methods of displaying identification and specific other data (including operational data) on the ILU by means of permanent marks are included. This European Standard specifies: a) an ILU identification system with an associated system for verifying the accuracy of its use, having mandatory marks for the presentation of the identification system for visual interpretation, and b) a coding system for data on ILU size, with corresponding marks for their display; c) mandatory operational marks; d) physical presentation of the marks on the ILU. This part of the European Standard prescribes the system of operational data for the codification of the semi-trailer. The codification assigns a maximum profile for the cover area available at the rail tracks to the semi-trailer in order to enable the selection of those rail tracks on which these semi-trailers can be transported without any danger. This part of the European Standard prescribes furthermore the additional operational markings, which are necessary for railway operation. This European Standard does not cover temporary operational marks of any kind, permanent marks, data plates, etc. which may be required by intergovernmental agreements, national legislation or non-governmental organisations other than CEN.
