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.
