This part of ISO/IEC 15415
¿ 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 twodimensional
matrix symbologies;
¿ defines methods for evaluating and grading these measurements and deriving an overall assessment of
symbol quality;
¿ gives information on possible causes of deviation from optimum grades to assist users in taking
appropriate corrective action.
This International Standard 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.
