significance And Use:

scope:

1.1 This practice describes a specific procedure for using a bar code verifier to measure and quantify the optical and symbology characteristics relative to the print quality of a bar code symbol and its performance within a bar code reading system. Measurements taken with bar code verifiers should conform to ANSI ANS X3.182-1995 [R] methodology. Various printing methods including direct thermal, thermal transfer, electrophotographic, dot matrix, and ink jet methods are used to produce bar code symbols. Use of this procedure will help assure repeatability of measurements between operators and pieces of equipment and traceability of those measurements.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
