23、5426-2:2006 (E) 4 Introduction 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 patterns, known as the symbology specification. Symbolo

24、gy 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 codes. Multi-row bar codes are constructed graphi

25、cally 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 characteristics of a linear bar code symbol and may be rea

26、d 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 determine its significance, and the symbol must there

27、fore 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 such a way as to be reliably decoded at the poi

28、nt 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. Manufacturers of bar code equipment, the producers of ba

29、r 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 of ISO/IEC 15426 is intended to be similar in te

30、chnical 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, which provides symbology-specific detail necessary f

31、or its application.

32、 and two-dimensional matrix symbologies, and specifies reference calibration standards against which these should be tested. This part of ISO/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 Conformanc

34、multi-row bar code symbols) or five measurements (for two-dimensional matrix symbols) of individual reported parameters are within the tolerances shown in Table 1 below.
