Bibliography

Defines: - the methodology for the measurement of specific attributes of bar code symbols; - a method for evaluating these measurements and deriving an overall assessment of symbol quality; - information on possible causes of deviation from optimum grades to assist users in taking appropriate corrective action.

This International Standard

• 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;

• gives information on possible causes of deviation from optimum grades to assist users in taking appropriate corrective action.

This International Standard 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.
