ASTM F 1851 Document Information:
Title
Standard Practice for Bar Code Verification
ASTM International
Publication Date:
Feb 10, 1998
Scope:
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.
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.
