Overview
ISO/IEC TR 24244:2022 is a technical report that explains the changes introduced in ISO/IEC 15416:2016 compared with the 2000 edition. It documents the evolution of bar code print quality grading and measurement for linear symbols, why the changes were made, and their practical impact for users in industry and standards development.
Key topics
- Historical background - lineage from ANSI X3.182 and widespread use of ISO/IEC 15416 across industries (retail POS, supply chain, warehousing, logistics, pharmaceutical labelling).
- Continuous grading - change from five integer grade levels (0–4) to a finer scale of 41 steps (0.0 to 4.0 in 0.1 increments). This reduces abrupt grade jumps and measurement variability.
- Defect measurement changes - introduction of a weighting scheme for peaks and valleys in scan reflectance profiles so very small fluctuations are discounted while larger defects (fully weighted at ~7.5% of symbol contrast) retain full impact.
- Measurement practice - final barcode grade is normally an average of multiple scan samples (preferably at least 10 equally spaced scans) and reported to the nearest tenth.
- Impact on application standards - the finer grading and tendency toward higher grades can affect acceptance thresholds in application standards that historically referenced minimum grades (e.g., the historical “C”/1.5 threshold).
Practical applications
- Quality control for barcode printing - helps label printers and converters reduce false failures and better track true print defects.
- Conformance testing and certification - test labs can apply continuous grading to generate more stable, representative quality scores for linear barcodes.
- Standards and procurement - standards authors and purchasing specifications can reassess minimum grade requirements (for instance, where 1.5 was commonly used) to align acceptance criteria with ISO/IEC 15416:2016 behavior.
- Scanner performance correlation - by reducing grade variability and reflecting modern scanning capabilities, the revised grading improves the relationship between measured grade and real-world read rates.
Who should use this report
- Barcode quality engineers, print and label manufacturers, compliance test labs
- Systems integrators and logistics/retail quality teams
- Standards developers and regulators updating application-specific barcode requirements
