scope:

This part of ISO/IEC 15415

Specifies tow methodologies for the measurement of specific attributes of two-dimensional bar code symbols, one of these being applicable to multi-row bar code symbolgies and the other to two dimensional 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.
