CSA 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). For brevity, this Standard will be referred to as \"CAN/CSA-ISO/IEC 24724\" throughout. This Standard has been formally approved, without modification, by the Technical Committee and has been approved as a National Standard of Canada by the Standards Council of Canada. Scope This International Standard defines the requirements for the GS1 DataBar symbology family. It specifies the characteristics of the GS1 DataBar symbology family, data character encodation, symbol formats, dimensions, print quality requirements, error detection, and decoding algorithms. For GS1 Composite symbols, ISO/IEC 24723 defines the two-dimensional component.
