ISO/IEC 15426-2:2015 defines test methods and minimum accuracy criteria applicable to verifiers using the methodologies of ISO/IEC 15415 for multi-row bar code symbols and two-dimensional matrix symbologies, and specifies reference calibration standards against which these should be tested. It provides for testing of representative samples of the equipment.
NOTE ISO/IEC 15426-1 applies to verifiers for linear bar code symbols.
