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 Canadian Advisory Committee (CAC) 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). This Standard supersedes CAN/CSA-ISO/IEC 15421-02 (adoption of ISO/IEC 15421:2000, first edition, 2000-09-15). At the time of publication, ISO/IEC 15421:2010 is available from ISO and IEC in English only. CSA will publish the French version when it becomes available from ISO and IEC. Scope This International Standard specifies the requirements and test methods for physical and related attributes of a bar code master. It covers all forms of bar code master, irrespective of the mode of origination of the initial image, intended for reproduction by conventional printing processes. This International Standard does not cover processes in which there is no master, such as computer to plate (CTP).
