BS ISO IEC 24723 pdf download Information technology — Automatic identification and data capture techniques — GS1 Composite bar code symbology specification
1 Scope
This International Standard defines the requirements for the GS1 Composite symbology. It specifies the GS1 Composite symbology characteristics, data character encodation, symbol formats, dimensions and print quality requirements, error correction rules, and reference decoding algorithms. For those linear and 2D components of GS1 Composite symbols with published symbology specifications, those published specifications apply, except as specifically noted in this International Standard.

3 Terms, definitions, abbreviated terms and mathematical operators
3.1 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO/IEC 1 9762-1 , ISO/IEC 1 9762-2 and the following apply.
3.1.1
2D component
CC
two-dimensional portion of a GS1 Composite symbol, which encodes supplemental information about an item, such as its lot number or expiration date
3.1.2
AI element string
character string containing an application identifier followed by its associated data field
3.1.3
CC-A
2D component that is a structural variant of MicroPDF41 7
NOTE 1 CC-A components can be autodiscriminated from MicroPDF41 7 symbols, because CC-A components have a unique Rotation of 32 between any two adjacent Row Address Patterns.
NOTE 2 CC-A is one of the three choices for the 2D component in a symbol encoded in the GS1 Composite symbology.
3.1.4
CC-B
2D component that is a MicroPDF41 7 symbol which begins with PDF41 7 codeword 920, indicating conformance with this International Standard
NOTE CC-B is one of the three choices for the 2D component in a symbol encoded in the GS1 Composite symbology.
