10、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 est
11、ablished 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 t
12、he field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria need

This second edition cancels and replaces the first edition
17、(ISO/IEC 15416:2000), which has been technically revised with the following changes, as well as minor editorial modifications: the computation of “Defects” was modified in this revision of ISO/IEC 15416 (see Note 3 in 5.4.8); and sharp boundaries between grade levels are avoided by assigning grades
18、within grade boundaries to the first decimal place (see the Notes in 6.2.2 and 6.2.3).iv ISO/IEC 2016 All rights reserved ISO/IEC 15416:2016(E) Introduction The technology of bar coding is based on the recognition of patterns encoded in bars and spaces of defined dimensions according to rules defini
19、ng the translation of characters into such patterns, known as the symbology specification. The bar code symbol is produced in such a way as to be reliably decoded at the point of use, if it is to fulfil its basic objective as a machine readable data carrier. Manufacturers of bar code equipment and t
20、he producers and users of bar code symbols therefore require publicly available standard test specifications for the objective assessment of the quality of bar code symbols, to which they can refer to when developing equipment and application standards or determining the quality of the symbols. Such
21、 test specifications form the basis for the development of measuring equipment for process control and quality assurance purposes during symbol production, as well as afterwards. The performance of measuring equipment is the subject of a separate standard, ISO/IEC 15426-1. This document is to be rea
22、d in conjunction with the symbology specification applicable to the bar code symbol being tested, which provides symbology-specific detail necessary for its application. This methodology provides symbol producers and their trading partners a universally standardized means for communicating about the
23、 quality of bar code symbols after they have been printed.
