Overview
ISO 9999:2022 - Assistive products - Classification and terminology is the seventh edition (2022) of the international classification that standardizes how assistive products and related terminology are organized. The standard specifies a three-level, function-based classification (classes, subclasses, divisions) and a consistent coding system to describe assistive products - including devices, equipment and software - that optimize functioning and reduce disability. It also clarifies what is excluded (e.g., medicines, implanted devices, non-technical solutions, items used solely by healthcare professionals or teachers).
Key topics and technical structure
- Three-level hierarchy and codes: each item is located by a code composed of three pairs of digits (class / subclass / division). Codes determine position and support national extension.
- Function-based classification: products are classified by primary function; multifunctional products and software are classified by their principal function.
- Rules, titles and explanatory notes: classes/subclasses/divisions include titles, explanatory notes, inclusions, exclusions and cross-references to ensure consistent interpretation.
- Parts & accessories: parts and accessories are usually classified together with the associated product group or as close as possible when shared across groups.
- National adaptations: specific code ranges are reserved for national use (e.g., classes 01, 02, and 90–99 and corresponding subclass/division slots).
- Supporting material: Annexes include a conversion table from ISO 9999:2016 to 2022, membership in the WHO Family of International Classifications (WHO‑FIC), an updated definition of assistive product, and an alphabetical index to aid retrieval.
- Editorial changes: the 2022 edition includes substantive updates (e.g., deletion of a class in prior editions and major revisions to some classes) and about 23 new and 116 revised titles.
Practical applications
ISO 9999:2022 provides a uniform classification and terminology for:
- Procurement and inventory management of assistive technology
- Product labelling, catalogs and e-commerce listings for assistive devices and software
- Policy development, service planning and statistical reporting in rehabilitation and disability services
- Interoperability and data exchange between health and social care systems, registries, and research databases
- Manufacturers and product designers for consistent product categorization and market access
Who uses this standard
- Assistive technology manufacturers and suppliers
- Rehabilitation professionals, clinicians and occupational therapists
- Health and social care administrators, procurement officers and policy makers
- Insurers, registries and statistical agencies
- Accessibility and disability researchers, and IT developers building assistive‑technology software or inventory systems
Related standards and references
- International Classification of Functioning, Disability and Health (ICF, WHO) - used for harmonized terminology and framework
- ISO/IEC Directives and collaborations with CEN (CEN/TC 293) govern editorial and development context
