Overview
ISO/IEC 15417:2007/Amd 1:2026 is an amendment to the international standard for Code 128 bar code symbology specification. Developed by ISO/IEC Joint Technical Committee 1, Subcommittee 31, this document refines requirements related to automatic identification and data capture (AIDC) techniques, focusing specifically on Code 128, one of the most commonly used high-density, alphanumeric bar code standards in information technology and industry worldwide.
This amendment streamlines referenced terminology, enhances clarity around character value conversion, and ensures that implementations of Code 128 remain consistent, interoperable, and compatible with current international vocabulary.
Key Topics
- Updated References: Replaces outdated references to ISO/IEC 19762-1 and ISO/IEC 19762-2 with the consolidated ISO/IEC 19762, which standardizes vocabulary across AIDC technologies.
- Terminology and Definitions: Clarifies that terms and definitions used in the document shall conform to ISO/IEC 19762, ensuring international consistency in AIDC-related language.
- Annex D Revision: Provides updated guidance for the relationship between symbol character values and ASCII values in Code 128. Formulas are specified to accurately convert between symbol values and ASCII values, supporting software developers and system integrators.
- Code set A:
- If S ≤ 63: V = S + 32
- If 64 ≤ S ≤ 95: V = S - 64
- Code set B:
- Describes the effect of special function characters, such as FNC4, for additional ASCII values.
- Alignment to International Character Encoding: Notes that ASCII values referenced align with the ISO/IEC 646 IRV coded character set, facilitating compatibility with global IT systems.
Applications
Code 128 bar code symbology is widely adopted in numerous industries for its ability to encode a wide range of data efficiently and reliably. This amendment to ISO/IEC 15417 is relevant for:
- Manufacturing and Logistics: Enables accurate product identification, inventory tracking, and supply chain management by ensuring seamless data capture and exchange between different IT systems.
- Retail and Distribution: Supports automated checkout, point-of-sale scanning, and stock control by maintaining globally recognized bar code standards.
- Healthcare: Facilitates patient identification, medication tracking, and medical asset management, where reliable and standardized bar code interpretation is critical.
- Software Development: Guides application developers and hardware integrators in ensuring that encoding and decoding routines for Code 128 comply with internationally accepted formulas and character associations.
- Data Interoperability: Promotes consistent data formatting and interpretation across borders and platforms through standardized character encoding and bar code printing.
