CAN/CSA-ISO/IEC 15416:18

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 — provides 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.
