ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and
10、 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 Directives, Part 2. The m

This second edition cancels and replaces the first edition (ISO/IEC 15417:2000), which has been technically revised. BS ISO/IEC 15417:2007v Introduction The technology of bar coding is based on the recognition o
14、f patterns encoded in bars and spaces of defined dimensions. There are numerous methods of encoding information in bar code form, known as symbologies. Code 128 is one such symbology. The rules defining the translation of characters into bar and space patterns, and other essential features of each s
15、ymbology, are known as the symbology specification. In the past, symbology specifications were developed and published by a number of organizations, resulting in certain instances in conflicting requirements for certain symbologies. Manufacturers of bar code equipment and users of bar code technolog
16、y require publicly available standard symbology specifications to which they can refer when developing equipment and software.
