19、nal Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established b
20、y the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field o
21、f information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft Int
22、ernational Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this docum
23、ent may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO/IEC 15424 was prepared by Joint Technical Committee ISO/IEC JTC1, Information technology, Subcommittee SC 31, Automatic identification and data capture techniques. This secon
24、d edition cancels and replaces the first edition (ISO/IEC 15424:2000), which has been technically revised.

25、 need exists to identify the data carrier a reader detects in autodiscrimination environments. The Symbology Identifier concept provides a standardized way for a device receiving data from a reader to differentiate between the data carriers. This International Standard deals mostly with bar code sym
26、bologies; the terms Symbology Identifier, symbology, and bar code are therefore used throughout this International Standard although they are intended to apply to other data carriers as well. This identification is achieved by the addition of an optional feature to readers enabling the reader to pre
27、fix a standard string of characters to data messages. This preamble contains information about the decoded symbol (or other data carrier) and any processing the reader has done. The information is not encoded or otherwise explicitly or implicitly represented in the symbol, except that the presence o
28、f some optional features may be detected by the reading equipment, whereas others require the reader to be expressly configured to implement them. This International Standard is intended to be read in conjunction with the relevant symbology specifications. SANS 15424:2009This s tandard may only be u

30、 Automatic identification and data capture techniques Data Carrier Identifiers (including Symbology Identifiers) 1 Scope This International Standard applies to automatic identification device communication conventions and standardizes the reporting of data carriers from bar code readers and other au
31、tomatic identification equipment. It specifies a preamble message generated by the reader and interpretable by the receiving system, which indicates the bar code symbology or other origin of transmitted data, together with details of certain specified optional processing features associated with the
32、 data message. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

39、ymbologies for which a symbology specification has been published by ISO/IEC JTC 1, AIM Global, or another recognized international standards body. In addition there is a fixed number of symbologies which do not have a full standard but do have a reference document available from AIM Global. These s
40、ymbologies are included in this International Standard because of their historical usage. 4.2 Structure The symbology identifier shall be an ASCII character string prefixed by the reading equipment to the data contained in a bar code symbol. The structure of the symbology identifier string shall be
41、as follows: cm. where (ASCII value 93) represents the symbology identifier flag character; c represents the code character as defined in Table 1; m. represents the modifier character(s) as defined for the symbology in question. NOTE The sign is the character assigned to ASCII value 93 in the United
42、States ASCII character set in accordance with ISO/IEC 646. If a reader is enabled to transmit symbology identifiers, it shall always transmit a symbology identifier at the beginning of each message. The application must know whether or not the reader has symbology identifiers enabled. Therefore, the
43、 symbol data may start with a and still be interpreted unambiguously. When these ASCII characters are transmitted in a 16-bit (double byte) system, an 8-bit byte of all zeros shall be transmitted before each of the above ASCII characters (bytes).

44、inted by approved subscription and freemailing clients of the SABS .ISO/IEC 15424:2008(E) ISO/IEC 2008 All rights reserved 34.3 Code characters Code characters shall be drawn from the set of upper- and lower-case alphabetic letters A through Z (ASCII values 65 through 90) and a through z (ASCII valu
45、es 97 through 122). The currently assigned code characters are listed in Table 1. These code characters are case sensitive, i.e. a capital “A” is a different code character from a lower case “a”. The code character Y is not assigned to a specific symbology but will be used for system expansion. The
46、first modifier character following Y will be a digit from 1 to 9 defining the number of remaining modifier characters in the symbology identifier prefix string. All code characters not given here are reserved for future use. Maintenance of the list of code characters (and of options given in 4.3) sh
47、all be in accordance with annex A of this International Standard. Certain symbologies emulate the data content of other symbologies, using their assigned symbology identifier. See annex B.
