BS ISO IEC 24723:2010 pdf free 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 GS1Composite symbology. t specifies the GS1Composite symbology characteristics，data character encodation, symbol formats,dimensions and printquality requirements，error correction rules,and reference decoding algorithms. For those linear and 2Dcomponents of GS1 Composite symbols with published symbology specifications，those publishedspecifications apply, except as specifically noted in this International Standard.

3Terms, definitions, abbreviated terms and mathematical operators3.1Terms and definitions
For the purposes of this document, the terms and definitions given in lSOIEC 19762-1, ISOIEC 19762-2 andthe following apply.
3.1.1
2Dcomponentcc
two-dimensional portion of a GS1Composite symbol, which encodes supplemental information about an item,such as its lot number or expiration date
3.1.2
Al 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 MicroPDF417
NOTE 1 CC-A components can be autodiscriminated from MicroPDF417 symbols, because CC-A components have aunique Rotation of 32 between any two adjacent Row Address Patterns.
NOTE2 CC-A is one of the three choices for the 2D component in a symbol encoded in the GS1 Compositesymbology.
3.1.4
cc-B
2D. component that is a MicroPDF417 symbol which begins with PDF417 codeword 920， indicatingconformance with this International Standard
NOTE CC-B is one of the three choices for the 2D component in a symbol encoded in the Gs1 Compositesymbology.
