22、2:2006EN ISO/IEC 15426-2:2006 (E)iv Foreword ISO (the International Organization for Standardization) and IEC (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 In
23、ternational 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, governmental and non-governmental, in liai
24、son 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 main task of the joint tech
25、nical 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 national bodies casting a vote. Attention is
26、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 15426-2 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommit
27、tee SC 31, Automatic identification and data capture techniques. ISO/IEC 15426 consists of the following parts, under the general title Information technology Automatic identification and data capture techniques Bar code verifier conformance specification: Part 1: Linear symbols Part 2: Two-dimensio
28、nal symbols BS EN ISO/IEC 15426-2:2006EN ISO/IEC 15426-2:2006 (E)vIntroduction The technology of bar coding is based on the recognition of patterns encoded, in bars and spaces or in a matrix of modules of defined dimensions, according to rules defining the translation of characters into such pattern
29、s, known as the symbology specification. Symbology specifications may be categorised into linear symbols, on the one hand, and two-dimensional symbols on the other; the latter may in turn be sub-divided into multi-row bar codes sometimes referred to as stacked bar codes, and two-dimensional matrix c
30、odes. Multi-row bar codes are constructed graphically as a series of rows of symbol characters, representing data and overhead components, placed in a defined vertical arrangement to form a (normally) rectangular symbol, which contains a single data message. Each row of the symbol has the characteri
31、stics of a linear bar code symbol and may be read by linear symbol scanning techniques. Two-dimensional matrix symbols are usually rectangular arrangements of modules placed at the intersections of a grid of two (sometimes more) axes; the coordinates of each module need to be known in order to deter
32、mine its significance, and the symbol must therefore be analysed two-dimensionally before it can be decoded. Unless the context requires otherwise, the term symbol in this part of ISO/IEC 15426 may refer to either type of symbology. The symbol, as a machine-readable data carrier, must be produced in
33、 such a way as to be reliably decoded at the point of use, if it is to fulfil its basic objective. Standard methodologies have been developed for measuring and assessing the quality of symbols for process control and quality assurance purposes during symbol production as well as afterwards. Manufact
34、urers of bar code equipment, the producers of bar code symbols and the users of bar code technology require publicly available standard conformance specifications for measuring equipment applying these methodologies, to ensure the accuracy and consistency of performance of this equipment. This part
35、of ISO/IEC 15426 is intended to be similar in technical content (mutatis mutandis) to the linear bar code verifier conformance standard, ISO/IEC 15426-1, on which it has been based. It should be read in conjunction with the symbology specification applicable to the bar code symbol being tested, whic
36、h provides symbology-specific detail necessary for its application.

37、ISO/IEC 15426 defines test methods and minimum accuracy criteria applicable to verifiers using the methodologies of ISO/IEC 15415 for multi-row bar code symbols and two-dimensional matrix symbologies, and specifies reference calibration standards against which these should be tested. This part of IS
38、O/IEC 15426 provides for testing of representative samples of the equipment. NOTE ISO/IEC 15426-1 applies to verifiers for linear bar code symbols. 2 Conformance The instrument shall be considered to conform with this part of ISO/IEC 15426 if it performs the functions defined in 6.3 and if the resul
