Alcance
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.
