ISO 21007-1:2005

Overview

ISO 21007-1:2005 - "Gas cylinders - Identification and marking using radio frequency identification technology - Part 1: Reference architecture and terminology" defines a common framework for the data structure and terminology used to identify gas cylinders with RFID. It establishes a non-prescriptive, frequency- and air-interface‑agnostic reference architecture that enables interoperability across different commercial RFID systems while focusing solely on the data element structure (not on hardware, air interface or protocols).

Key topics and technical requirements

• Reference architecture for unambiguous identification of single or manifolded gas cylinders and related data elements.
• Numbering scheme architecture: views the Identification (ID) as a data element and defines a common basic structure as a data identifier code.
• Adoption of ASN.1 (Abstract Syntax Notation One) to encode data identifiers, enabling adaptability, expandability and minimal transmission/storage overhead.
• Interoperability and scalability: not tied to a specific frequency or air interface - supports high population capability and upward migration to more capable systems.
• EDI compatibility: data constructs can be recognized and used within Electronic Data Interchange environments to identify messages originating from gas cylinders.
• Terminology: authoritative definitions (e.g., transponder, interrogator, issuer, CSI) to ensure consistent use across industry implementations.
• Design principles: use existing standard codings where possible, avoid carrying unnecessary information, and provide mechanisms for harmonization among commercial systems.

Practical applications

• Unique RFID-based identification of gas cylinders for safety, inventory control, traceability and quality assurance.
• Encoding variable data (e.g., content type, fill date, batch, maintenance/test history) while keeping basic ID minimal for low-cost tags.
• Integration into supply-chain and logistics systems for automated tracking, EDI messaging and asset management.
• Supporting specialty gases, manifold configurations and diverse industry sectors (medical, industrial, research).

Who should use it

• Gas producers, bottlers and distributors (issuers) implementing RFID marking on cylinders.
• System integrators, RFID solution providers and software vendors building EDI-compatible cylinder-tracking systems.
• Asset management, compliance and safety teams seeking consistent, interoperable identification schemes for cylinders.
• Standards developers and regulatory bodies aligning labeling/identification practices.

Related standards

• ISO 21007-2 (Numbering schemes for RFID) - subsequent part that defines specific data structures.
• ISO/IEC 8824 & 8825 - ASN.1 encoding standards referenced by ISO 21007-1.
• ISO 13769, ISO 32, ISO 7225 - related cylinder marking and labeling standards cited for traditional identification methods.
• ISO 9897 - referenced EDI message structure compatibility.
