What is ISO/IEC 15415?
ISO/IEC 15415 is the international standard that defines how to evaluate the print quality of two-dimensional barcodes, such as QR codes, Data Matrix, and Aztec codes. This standard ensures that 2D barcodes are consistently scannable by verifiers and scanners under controlled conditions, reducing errors in industries like healthcare, logistics, and manufacturing. In this post, we’ll explore how ISO 15415 works, its key parameters, and why businesses should prioritise 2D barcode verification to ensure data accuracy and global compliance.
Key Parameters Graded Under ISO/IEC 15415
- Symbol contrast: Measures the difference in brightness between the light and dark areas of the barcode.
- Modulation: Assesses how evenly the contrast is maintained across the entire symbol.
- Unused error correction: Indicates how much of the barcode’s built-in error correction capacity remains available, which reflects how well the symbol is printed.
- Axial and grid non-uniformity: Evaluate how well the barcode’s modules align to a perfect grid, which affects scanner accuracy.
- Fixed pattern damage: Checks for defects in the essential patterns that help scanners locate and interpret the barcode.
How ISO 15415 Verification Works
Verification is performed under standardized lighting and viewing conditions, using calibrated equipment. By following ISO/IEC 15415, businesses can ensure their 2D barcodes are reliable, scannable, and compliant with global quality expectations.
