ISO/IEC 15419:2009描述了条形码数字成像系统的特征和分类，确定了需要控制的每个系统的属性，并规定了这些属性的最低要求。它定义了评估这些属性与ISO/IEC 15419:2009一致性的测试方法。它旨在与国际标准结合使用，这些标准详细说明了评估条形码符号质量的方法，如ISO/IEC 15416。ISO/IEC 15419:2009不适用于ISO/IEC 15421涵盖的条形码母版。

ISO/IEC 15419:2009 describes the characteristics and defines categories of bar code digital imaging systems, identifies the attributes of each system which are required to be controlled, and specifies minimum requirements for those attributes. It defines test methods for assessing the conformance of those attributes with ISO/IEC 15419:2009. It is intended to be used in conjunction with International Standards which detail the methodology for assessing the quality of a bar code symbol, such as ISO/IEC 15416. ISO/IEC 15419:2009 does not apply to Bar Code Masters, which are covered by ISO/IEC 15421.
