Foreword
ISO (the International 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 by 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 of 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 International
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 document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 15423 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 31, Automatic identification and data capture techniques.
This first edition cancels and replaces ISO/IEC 15423-1:2001, which has been technically revised.

ISO/IEC 15423:2004(E)
Introduction
The technology of bar coding is based on the recognition of patterns encoded in bars and spaces of defined
dimensions or arrangements of marks in matrix patterns both of which are constructed according to rules
defining the translation of characters into such patterns, known as the symbology specification.
Bar code symbols can be produced with a wide variety of printing and other techniques, and the overall
symbol dimensions can be uniformly scaled to suit particular requirements.
There is a wide range of bar code reading equipment using various scanning techniques, which enable bar
code symbols to be read under many different conditions.
Bar code symbols may be a) “linear” i.e. read in a single dimension, where the height of the bars provides
redundancy of information, or b) “two dimensional”, either in stacked rows to be read unidimensionally with
multiple scans, or as a matrix of elements requiring two dimensional reading.
Bar code reading equipment must be capable of reliably converting the information represented as a bar code
symbol into a form meaningful to the host computer system or otherwise to the user.
Manufacturers of bar code equipment, the producers of bar code symbols and the users of bar code
technology require publicly available standard test specifications for bar code reading equipment to ensure the
accuracy and consistency of performance of this equipment.

performance testing
1 Scope
This International Standard defines the test equipment and procedures to be used to determine the
performance of bar code scanning and decoding equipment. It deals with bar code scanning and decoding
equipment both as integrated reading systems and as discrete units. It defines performance of the equipment
in a particular configuration (e.g. a specific model) irrespective of the individual components used. It also
defines in a normative annex operational parameters for the test equipment, and describes, in an informative
annex, a means of classifying scanners.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO/IEC 19762 and the following apply.
3.1
contact scanner
particular type of scanner in which the scanning action takes place with the scanner in actual or near contact
with the symbol, e.g. wand or light pen
3.2
composite symbology
bar code symbol composed of both a linear bar code symbol and a two-dimensional bar code symbol
3.3
decode redundancy
acquisition of a predetermined number of identical decodes before acceptance by a decoder of a valid decode
EXAMPLE Decode redundancy of 2 requires two identical decodes.
3.4
exit window
datum point from which the reading diagram is measured, positioned on the beam midpoint and closest to the
reading end of the scanner
3.5
maximum reading distance
distance from the exit window to the end of the depth of field
NOTE See R in Figure 2.
3.6
minimum reading distance
distance from the exit window to the beginning of the depth of field

3.7
raster
projection of a laser beam to create multiple, nearly parallel scan lines instead of a single line
3.8
raster distance
distance between the two most widely spaced adjacent scan lines projected on a plane at a defined distance

See D in Figure B.3.
3.10
reading angle
angular rotation of a symbol in an axis relative to a scan line
NOTE Three different reading angles, tilt, skew and pitch are illustrated in Figure 1. Tilt refers to rotation around the

5 Categories of scanning equipment
In order to enable the most appropriate set of tests for a given scanning device or unit to be selected,
scanners are grouped for the purposes of this International Standard into three categories. The basis for this
categorisation is the nature of the reading diagram applicable. Examples of various types of scanners are
given in Annex B. Each category may be further subdivided into ‘continuously operating’ scanners, in which
the scanning operation is already in progress when the symbol enters the reading zone, and ‘triggered’
scanners, where the symbol is already in the reading zone when the scanning operation is initiated.
