ISO 21849:2022

Overview

ISO 21849:2022 - "Aircraft and space - Industrial data - Product identification and traceability" defines a standardized schema and repeatable processes for identifying and tracing aircraft and space products/parts throughout their life cycle. The standard specifies the minimum essential identification information, data structures for use with automatic identification technologies (matrix symbologies, linear bar codes, RFID), and rules to establish a unique, permanent identifier that supports interoperability across manufacturers, suppliers, operators and maintenance organizations.

Key topics and technical requirements

• Unique identifier structure and rules: Defines how to create and manage permanent product/part identifiers that persist across ownership, repairs and configuration changes.
• Conformance classes: Provides classes to accommodate different identification practices and implementation needs (see Clauses on Conformance class 1 and 2).
• Data formats and element identifiers: Specifies supported data formats and machine-readable element schemes, including text element identifiers, GS1 application identifiers and ASC MH10 (codified in ISO/IEC 15418) mappings.
• Product/part marking: Guidance for direct marking, labels/nameplates, and marking symbologies (matrix symbols, linear bar codes), including layout, human-readable translation and extended data content.
• Automatic identification technologies: Requirements for using RFID tags, matrix codes and bar codes, including associated dimensional and quality parameters for machine-readability.
• Data dictionaries and annexes: Normative data dictionaries of essential and optional data elements, plus informative annexes on life‑cycle traceability, legacy schemas, encoding comparisons, and data exchange.
• Interoperability and repeatability: Emphasis on machine-readable media and standardized data structures to enable error-free data entry, configuration, reliability and maintenance management.

Practical applications and users

ISO 21849:2022 is intended for organizations that design, produce, certify, maintain or supply aircraft and space components, including:

• OEMs and parts manufacturers
• MRO providers and airlines
• Defense contractors and space agencies
• Logistics, inventory and supply‑chain teams
• Regulatory and quality assurance bodies

Typical uses include serialized part marking, life‑cycle traceability, configuration and maintenance records, counterfeit detection, inventory control, and automated data capture in production and service flows. The standard also supports tailored implementation guidelines between trading partners.

Related standards

• ISO/IEC 15418 (ASC MH10 data identifiers) - mapping and equivalencies referenced by ISO 21849.
• GS1 application identifier schemes - used for interoperability with commercial supply‑chain systems.
• ISO/IEC 646 and other cited normative references governing character sets and encoding.

Adopting ISO 21849:2022 helps aviation and space organizations improve data accuracy, automate identification workflows, and enable efficient cross‑enterprise exchange of life‑cycle product information.
