ISO/IEC 15416:2025

This document
—     specifies the methodology for the measurement of specific attributes of bar code symbols,
—     defines a method for evaluating these measurements and deriving an overall assessment of symbol quality, and
—     gives information on possible causes of deviation from optimum grades to assist users in taking appropriate corrective action.
This document applies to those symbologies for which a reference decode algorithm has been defined, and which are intended to be read using linear scanning methods, but its methodology can be applied partially or wholly to other symbologies.
