21、EC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with

22、particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, 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

23、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 main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint t

24、echnical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national 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. IS

25、O and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 15423 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 31, Automatic identification and data capture techniques. This second edition cancels and replaces the

26、 first edition (ISO/IEC 15423:2004), which has been technically revised. BS EN ISO/IEC 15423:2010EN ISO/IEC 15423:2010 (E) ISO/IEC 2011 All rights reserved vIntroduction The technology of bar coding is based on the recognition of patterns encoded in bars and spaces of defined dimensions or arrangeme

27、nts of marks in matrix patterns both of which are constructed according to rules defining the translation of characters into such patterns, known as the symbology specification. Bar code symbols can be produced with a wide variety of printing and other techniques, and the overall symbol dimensions c

28、an be uniformly scaled to suit particular requirements. There is a wide range of bar code reading equipment using various scanning techniques, which enable bar code symbols to be read under many different conditions. Bar code symbols may be a) “linear” i.e. read in a single dimension, where the heig

29、ht of the bars provides redundancy of information, or b) “two dimensional”, either in stacked rows to be read unidimensionally with multiple scans, or as a matrix of elements requiring two dimensional reading. Bar code reading equipment must be capable of reliably converting the information represen

30、ted as a bar code symbol into a form meaningful to the host computer system or otherwise to the user. Manufacturers of bar code equipment, the producers of bar code symbols and the users of bar code technology require publicly available standard test specifications for bar code reading equipment to

31、ensure the accuracy and consistency of performance of this equipment.

32、 1 Scope This International Standard defines the test equipment and procedures to be used to determine the performance of bar code scanning and decoding equipment. It deals with bar code scanning and decoding equipment both as integrated reading systems and as discrete units. It defines performance

33、of the equipment in a particular configuration (e.g. a specific model) irrespective of the individual components used. It also defines in a normative annex operational parameters for the test equipment, and describes, in an informative annex, a means of classifying scanners. 2 Normative references T
