Information technology — Automatic identification and data capture techniques — Bar code symbol print quality test specification — Two-dimensional symbols

This document
 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 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 document 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.

Note While this document may be applied to direct part marks, it is possible that better correlation between measurement results and scanning performance will be obtained with ISO/IEC 29158 in combination with this document.
