46、on of patterns encoded in bars and spaces of defineddimensions according to rules defining the translation of characters into such patterns, known as the symbologyspecification.The bar code symbol must be produced in such a way as to be reliably decoded at the point of use, if it is to fulfil itsbas

47、ic objective as a machine readable data carrier.Manufacturers of bar code equipment and the producers and users of bar code symbols therefore require publiclyavailable standard test specifications for the objective assessment of the quality of bar code symbols, to which theycan refer when developing

48、 equipment and application standards or determining the quality of the symbols. Suchtest specifications form the basis for the development of measuring equipment for process control and qualityassurance purposes during symbol production as well as afterwards.The performance of measuring equipment is

49、 the subject of a separate International Standard, ISO/IEC 15426.This International Standard is intended to be substantially equivalent in technical content to EN 1635 and ANSIstandards X3.182 - 1990 and ANSI/UCC5 on which it has been based. It should be read in conjunction with thesymbology specification applicable to the bar code symbol being tested, which provides symbology-specific detailnecessary for its application.There are currently many methods of assessing bar code quality at different sta
