scope:

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.
