16、m for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees col
17、laborate 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 of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standar
18、ds 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 International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication
19、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 document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such paten
20、t rights. ISO/IEC 19762-1 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 31, Automatic identification and data capture techniques. This second edition cancels and replaces the first edition (ISO/IEC 19762-1:2005), which has been technically revised.
21、ISO/IEC 19762 consists of the following parts, under the general title Information technology Automatic identification and data capture (AIDC) techniques Harmonized vocabulary: Part 1: General terms relating to AIDC Part 2: Optically readable media (ORM) Part 3: Radio frequency identification (RFID)
22、 Part 4: General terms relating to radio communications Part 5: Locating systems SANS 19762-1:2009This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .ISO/IEC 19762-1:2008(E) ISO/IEC 2008 All rights reserved vIntroduction ISO/IEC 19762 is intended
23、 to facilitate international communication in information technology, specifically in the area of automatic identification and data capture (AIDC) techniques. It provides a listing of terms and definitions used across multiple AIDC techniques. Abbreviations used within each part of ISO/IEC 19762 and
24、 an index of all definitions used within each part of ISO/IEC 19762 are found at the end of the relevant part.

26、of ISO/IEC 19762 provides general terms and definitions in the area of automatic identification and data capture techniques on which are based further specialized sections in various technical fields, as well as the essential terms to be used by non-specialist users in communication with specialists
27、 in automatic identification and data capture techniques. 2 Classification of entries The numbering system employed within ISO/IEC 19762 is in the format nn.nn.nnn, in which the first two numbers (nn.nn.nnn) represent the “Top Level” reflecting whether the term is related to 01 = common to all AIDC
28、techniques, 02 = common to all optically readable media, 03 = linear bar code symbols, 04 = two-dimensional symbols, 05 = radio frequency identification, 06 = general terms relating to radio, 07 = real time locating systems, and 08 = MIIM. The second two numbers (nn.nn.nnn) represent the “Mid Level”
29、 reflecting whether the term is related to 01 = basic concepts/data, 02 = technical features, 03 = symbology, 04 = hardware, and 05 = applications. The third two or three numbers (nn.nn.nnn) represent the “Fine” reflecting a sequence of terms. The numbering in this part of ISO/IEC 19762 employs “Top
30、 Level” numbers (nn.nn.nnn) of 01. 3 Terms and definitions 01.01.01 data reinterpretable representation of information in a formalized manner suitable for communication, interpretation, or processing cf. information ISO/IEC 2382-1:1993, 01.01.02 NOTE 1 Data can be processed by humans or by automatic
