Описание (английский):

This document specifies the test methods for representative samples of the equipment and the minimum accuracy criteria applicable to verifiers using the methodologies of ISO/IEC 15415 for multi-row bar code symbols and two-dimensional matrix symbologies. This document also specifies reference calibration standards for verifier conformance. NOTE ISO/IEC 15426-1 applies to verifiers for linear bar code symbols.

Overview

ISO/IEC 15426-2:2023 is the international conformance specification for bar code verifiers that assess two-dimensional symbols (including multi-row/stacked bar codes and matrix symbologies). It defines the test methods, minimum accuracy criteria, and reference calibration standards for verifiers that apply the ISO/IEC 15415 print-quality methodology. The standard ensures verifier measurements are accurate, repeatable and traceable to primary reference test symbols.

Key topics and technical requirements

Scope and purpose: Applies to verifiers for multi-row and two‑dimensional matrix symbols; ISO/IEC 15426-1 covers linear symbols.

Test methods and sampling: Specifies how to select representative equipment samples and perform measurements (Clause 8). Arithmetic means of measurements (10 for multi-row, 5 for matrix) must meet tolerances.

Accuracy tolerances: Examples of required tolerances include R and Rmax/Rmin reflectance (±5% and ±3% respectively), and symbol-specific parameter tolerances (e.g., decodability, defects, codeword yield, grid/axial nonuniformity). Fixed-pattern damage for Aztec code is addressed.

Reflectance calibration: Verifiers must support calibration against reference reflectance materials (two calibration points near high and low reflectance), traceable to the ISO/IEC 15415 reference.

Mandatory functions:

For multi-row bar codes: collect multi-scan reflectance profiles, analyse profiles, report profile and overall grades, report codeword yield, unused error correction and decoded data.
For matrix symbols: capture framed grey-scale area including quiet zones, produce reference grey-scale and binarized images, and compute matrix-specific metrics.

Construction/operational requirements: Installation, power, temperature/humidity ranges, ambient light immunity and maintenance expectations are specified.

Reference test symbols and reporting: Primary reference test symbols and verification requirements are normative; test reports and labelling/declaration rules are mandated.

Applications and who uses it

Verifier manufacturers: design and validate conformance of hardware and software verifiers.

Barcode printers and label producers: ensure printed two‑dimensional symbols meet quality criteria for downstream scanning.

Quality assurance and production: define acceptance testing and process control for symbol production.

System integrators and purchasers: evaluate and procure compliant verifier equipment for logistics, retail, healthcare, manufacturing and supply-chain systems.

Regulatory and certification bodies: establish objective measurement baselines and traceability for interoperability.
