National bodies that are members of ISO
20、 or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations
21、, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directi
22、ves, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the n
23、ational bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 24723 was prepared by Joint Technical Committee ISO/IE
24、C JTC 1, Information technology, Subcommittee SC 31, Automatic identification and data capture techniques. This second edition cancels and replaces the first edition (ISO/IEC 24723:2006), which has been technically revised. BS ISO/IEC 24723:2010ISO/IEC 24723:2010(E) vi ISO/IEC 2010 All rights reserv
25、edIntroduction Composite symbologies are a class of bar code symbology, the principal distinguishing feature of which is that they comprise two, or more, components, each of which is a distinct symbol, but which contain a set of related data. Typically one component is a linear symbol containing pri
26、mary data, which can be read on its own in some areas of the application. The other component(s) is a two-dimensional symbol containing supplementary data which qualifies the primary message, and requiring all components to be read to extract the complete message. The GS1 Composite symbology is one
27、such symbology. The use of the symbology is intended to comply with the GS1 General Specifications. A GS1 Composite symbol consists of a linear component (encoding the items primary identification) associated with an adjacent 2D component (encoding supplementary data, such as a batch number or expir
28、ation date). The GS1 Composite symbol always includes a linear component so that the primary identification is readable by all scanning technologies, and so that 2D imagers can use the linear component as a finder pattern for the adjacent 2D component. The GS1 Composite symbol always includes a mult
29、i-row 2D component, for compatibility with linear and 2D imagers, and with linear and rastering laser scanners. GS1 Composite symbols are intended for encoding identification numbers and data supplementary to the identification in accordance with the GS1 General Specifications. The administration of
30、 the numbering system by GS1 ensures that identification codes assigned to particular items are unique world-wide and that they and the associated supplementary data are defined in a consistent way.

It specifies the GS1 Composite symbology characteristics, data character encodation,
32、 symbol formats, dimensions and print quality requirements, error correction rules, and reference decoding algorithms. For those linear and 2D components of GS1 Composite symbols with published symbology specifications, those published specifications apply, except as specifically noted in this Inter
