本文件提供了一个识别和显示货运集装箱信息的系统。识别系统用于一般应用，例如在文件、控制和通信（包括自动数据处理系统）中，以及用于在容器本身上显示。 包括通过永久标记在容器上显示标识和某些其他数据（包括操作数据）的方法。 本文件规定: a） 一种集装箱识别系统，具有用于验证其使用准确性的相关系统，具有: -视觉判读识别系统呈现的强制性标志，以及 -用于可选自动设备识别（AEI）和电子数据交换（EDI）的功能； b） 集装箱尺寸和类型数据的编码系统，以及相应的显示标记； c） 操作标记，强制和可选； d） 容器上标记的物理呈现。 本文件中的术语“强制性”和“可选”用于区分所有容器必须满足的ISO标记规定与所有容器不需要的ISO标记规定。包含可选标记是为了进一步理解和促进可选标记的统一应用。如果选择显示可选标记，则应适用本文件中与该标记相关的规定。术语“强制性”和“可选”并不指任何监管机构的要求。 本文件适用于国际标准ISO 668、ISO 1496第1部分至第5部分、ISO 8323涵盖的所有货运集装箱，并应在适当和可行的情况下适用于: -适用于第2条所述国际标准涵盖范围以外的集装箱； -至容器相关和/或可拆卸设备。 注1:根据ISO 6346先前版本标记的容器无需重新标记。 本文件不包括政府间协议、国家立法或非政府组织可能要求的任何类型的临时操作标志、永久标志、铭牌等。 注2:本文件未涵盖集装箱标记要求的一些主要国际公约如下: -《国际集装箱安全公约》（1972年，经修订）（CSC），国际海事组织（IMO）； -1956年和1972年集装箱海关公约，涉及临时入境和海关封印运输。 -《临时入境公约》（1990年6月26日，伊斯坦布尔），与临时入境有关。 不应假设此列表是详尽的。 本文件不包括罐式集装箱技术数据的显示（见ISO 1496）- 3） 也不以任何方式包括可能在货运集装箱中运输的货物的识别标志或安全标志。

This document provides a system for the identification and presentation of information about freight containers. The identification system is intended for general application, for example in documentation, control and communications (including automatic data processing systems), as well as for display on the containers themselves. The methods of displaying identification and certain other data (including operational data) on containers by means of permanent marks are included. This document specifies: a) a container 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 —    features to be used in optional Automatic Equipment Identification (AEI) and electronic data interchange (EDI); b) a coding system for data on container size and type, with corresponding marks for their display; c) operational marks, both mandatory and optional; d) physical presentation of marks on the container. The terms “mandatory” and “optional” in this document are used to differentiate those ISO marking provisions which shall necessarily be fulfilled by all containers from those which are not required of all containers. The optional marks are included to further comprehension and promote uniform application of the optional mark. If a choice has been made to display an optional mark, the provisions laid down in this document relating to the mark shall be applied. The terms “mandatory” and “optional” do not refer to requirements of any regulatory body. This document applies to all freight containers covered by International Standards ISO 668, parts 1 to 5 of ISO 1496, ISO 8323 and should, wherever appropriate and practicable, be applied: —    to containers other than those covered by the International Standards mentioned in Clause 2; —    to container-related and/or detachable equipment. NOTE 1    Containers marked according to previous editions of ISO 6346 need not be re-marked. This document does not cover temporary operational marks of any kind, permanent marks, data plates, etc. which may be required by intergovernmental agreements, national legislation or nongovernmental organizations. NOTE 2    Some of the major international conventions whose container-marking requirements are not covered in this document are as follows: —     International Convention for Safe Containers (1972, as amended) (CSC), International Maritime Organization (IMO); —     Customs Convention on Containers 1956 and 1972, related to temporary admission and transport under customs seal. —     Convention on Temporary Admission (Istanbul, 26 June 1990), related to temporary admission. It should not be assumed that this list is exhaustive. This document does not cover the display of technical data on tank containers (see ISO 1496-3), nor does it, in any way, include identification marks or safety signs for items of cargo which may be carried in freight containers.
