Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). For brevity, this Standard will be referred to as \"CAN/CSA-ISO/IEC 15426-2\" throughout. This Standard supersedes CAN/CSA-ISO/IEC 15426-2:07 (adopted ISO/IEC 15426-2:2005). At the time of publication, ISO/IEC 15426-2:2015 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC. Scope This part of 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 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.
