Information technology - Automatic identification and data capture techniques - Bar code print quality test specification - Two-dimensional symbols (ISO/IEC 15415:2004)
ISO/IEC 15415:2004(E) specifies two methodologies for the measurement of specific attributes of two-dimensional bar code symbols, one of these being applicable to multi-row bar code symbologies and the other to two-dimensional matrix symbologies; defines methods for evaluating and grading these measurements and deriving an overall assessment of symbol quality; and gives information on possible causes of deviation from optimum grades to assist users in taking appropriate corrective action.
ISO/IEC 15415:2004(E) applies to those two-dimensional symbologies for which a reference decode algorithm has been defined, but its methodologies can be applied partially or wholly to other similar symbologies.

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 15415 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 31, Automatic identification and data capture techniques.

ISO/IEC 15415:2004(E)
Introduction
The technology of bar coding is based on the recognition of patterns encoded, in bars and spaces or in a
matrix of modules of defined dimensions, according to rules defining the translation of characters into such
patterns, known as the symbology specification. Symbology specifications may be categorized into those for
linear symbols, on the one hand, and two-dimensional symbols on the other; the latter may in turn be sub-
divided into «multi-row bar code symbols» sometimes referred to as «stacked bar code symbols», and «two-
dimensional matrix symbols». In addition there is a hybrid group of symbologies known as «composite
symbologies»; these symbols consist of two components carrying a single message or related data, one of
which is usually a linear symbol and the other a two-dimensional symbol positioned in a defined relationship
with the linear symbol.
Multi-row bar code symbols are constructed graphically as a series of rows of symbol characters, representing
data and overhead components
