BS ISO IEC 24723:2010 pdf download – Information technology — Automatic identification and data capture techniques — GS1 composite bar code symbology specification
1Scope
This International Standard defines the requirements for the GS1 Composite symbology. It 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 published specifications 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 ISO/IEC 19762-1,ISOIEC 19762-2 andthe following apply.
3.1.1
2D componentcc
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
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.
3.1.5
cc-c
2Dcomponent that is a PDF417 symbol which begins with PDF417 codeword 920, indicating conformancewith this International Standard
NOTE cc-C is one of the three choices for the 2D component in a symbol encoded in the Gs1 Compositesymbology.
3.1.6
linear component
linear portion of a GS1 Composite symbol,which encodes the primary identification of an item
3.1.7
linkage flag
indicator encoded in a GS1 DataBar or GS1 -1 28 component to signal if a 2D component accompanies the linear component
3.1.8
RAP Rotation
difference between the number designating a Center or Right Row Address Pattern and the number
designating the nearest Row Address Pattern to the left, in the same row of a MicroPDF41 7 symbol, or a CC-A or CC-B component
3.2 Abbreviated terms
AI Application Identifier
3.3 Mathematical operators and notational conventions
For the purposes of this document, the following mathematical operators apply.
div integer division operator which discards the remainder
mod integer remainder after integer division
The following ISO notational conventions are used.
0,2 a comma between digits separates the integer from the decimal fraction (e.g. 0,2 equals 2/1 0) except when used as an (n,k) designation
1 2 345 a space between digits indicates factors of a thousand
4 Symbol description
4.1 Basic characteristics
A GS1 Composite symbol consists of a linear component associated with an adjacent 2D component. The characteristics of the GS1 Composite symbology are:
a) Encodable character set:
1 ) Both linear and 2D components encode a subset of ISO/IEC 646, consisting of the upper and lowercase letters, digits, and 21 selected punctuation characters.
2) The function character FNC1 and a Symbol Separator character.BS ISO IEC 24723 pdf download.
