Description (English):

This document — specifies two methodologies for the measurement of specific attributes of two-dimensional bar code symbols – one of which applies to multi-row bar code symbologies and the other to two-dimensional matrix symbologies; — specifies methods for evaluating and grading these measurements and deriving an overall assessment of symbol quality; — gives information on possible causes of deviation from optimum grades to assist users in taking appropriate corrective action. This document applies to two-dimensional symbologies for which a reference decode algorithm has been defined, however the methodologies in this document can be applied partially or wholly to other similar symbologies. NOTE While this document can be applied to direct part marks, better correlation between measurement results and scanning performance can be obtained with ISO/IEC 29158 in combination with this document.

Abstract

Overview

ISO/IEC 15415:2024 - Automatic identification and data capture techniques - Bar code symbol print quality test specification - Two-dimensional symbols - is the third edition of the international standard for assessing the print quality of two-dimensional (2D) bar code symbols. It defines objective measurement and grading methodologies for both multi-row bar code symbologies (stacked/row-based) and two-dimensional matrix symbologies (matrix/module-based). The standard specifies how to obtain and process test images, compute parameter scores, derive an overall symbol grade, and interpret deviations to support corrective action.

Key topics and technical requirements

Two measurement methodologies: one for multi-row (stacked) symbologies and one for matrix symbologies; methodologies can be applied fully or partially to similar symbologies where a reference decode algorithm exists.
Image acquisition and optical setup: requirements for obtaining test images, measuring aperture convolution, inspection area and measurement conditions.
Reference and processed images: guidance on raw, reference grey-scale and binarized images used for grading.
Grading parameters: includes symbol contrast (Rmin/Rmax), modulation, reflectance margin, fixed pattern damage, axial and grid non-uniformity, unused error correction, print growth, and additional image assessment parameters.
Grading methods: continuous (decimal) grading introduced in this edition, procedures for per-parameter grading and computation of an overall symbol grade.
Decode considerations: use of a reference decode algorithm and decode-based grading (e.g., codeword yield, unused error correction).
Guidance and diagnostics: annexes provide thresholding algorithms, interpretation of scan vs. symbol grades, selection of grading parameters, substrate characteristics, and parameter overlays.
Applicability to DPM: can be applied to direct part marks, but better correlation with scanning performance is achieved when combined with ISO/IEC 29158.

Practical applications and users

ISO/IEC 15415:2024 is used for:

Quality control and verification of 2D barcode production (labels, packaging, tickets, documents).
Verifier manufacturers to implement compliant measurement and grading functionality.
Equipment integrators and system developers ensuring barcode print/read reliability in supply chains, logistics, retail, healthcare and manufacturing.
Application specifiers and auditors defining acceptable symbol grades for operational requirements.
Process improvement: diagnosing printing defects and guiding corrective actions via parameter-level feedback.
