1 Scope
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.
