It provides a listing of terms and definitions used across multiple AIDC techniques.
22、Abbreviations used within each part of ISO/IEC 19762 and an index of all definitions used within each part of ISO/IEC 19762 are found at the end of the relevant part. 4 EN ISO/IEC 19762-1:2012 (E) DIN EN ISO/IEC 19762-1:2012-06 1 Scope This part of ISO/IEC 19762 provides general terms and definition

24、es. 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 techniques, 02 = common to all optically readable medi
25、a, 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” reflecting whether the term is related to 01 = basic
26、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 Level” numbers (nn.nn.nnn) of 01. 3 Terms and definit
