ISO/IEC 15426-1:2006 PDF

Overview

ISO/IEC 15426-1:2006 - Information technology - Automatic identification and data capture techniques - Bar code verifier conformance specification - Part 1: Linear symbols - defines how to test and certify the accuracy and consistency of bar code verifiers for linear (1D) bar code symbols. It specifies required verifier functions, test methods using primary reference test symbols, reflectance calibration requirements, and minimum accuracy tolerances for reported parameters to ensure reliable barcode quality assessments.

Key topics and requirements

• Conformance criteria
  • Verifiers must implement the mandatory functions in Clause 6.3 and produce measurement results (arithmetic mean of ten scans) within the tolerances in Table 1:
    • Rmax: ±5% reflectance
    • Rmin: ±3% reflectance
    • Decodability: ±0.08
    • Defects: ±0.08
  • Tests are performed on representative production samples selected per manufacturer quality control.
• Mandatory functions
  • Collect reflectance measurements along scan paths
  • Build and analyse scan reflectance profiles
  • Report individual parameter grades and overall symbol grade (including aperture diameter and peak wavelength)
  • Report decoded data and all encoded characters
• Reflectance calibration
  • Verifiers must provide means to calibrate reflectance against reference samples (two-point calibration near high and low reflectance).
• Test methods
  • Use primary reference test symbols manufactured to tight tolerances and traceable to national standards
  • Perform ten consecutive scans per symbol; compare reported values to supplied reference measurements
  • Tests conducted under manufacturer-specified environmental conditions (power, temperature, humidity, ambient light)
• Documentation & operational requirements
  • Manufacturer-specified installation, maintenance, power, temperature, humidity and ambient light conditions
  • Optional reporting functions (e.g., number of scans used, bar-width deviations, symbology)

Applications and users

• Ensures consistent, comparable barcode quality assessment across:
  • Barcode verifier manufacturers (product development and QC)
  • Barcode printer/label producers and converters (process control)
  • System integrators, logistics, retail, healthcare and manufacturing (quality assurance and compliance)
• Supports procurement and certification decisions where verifier accuracy and traceability are required
