Overview
ISO 14289-1:2014 (PDF/UA-1) - Document management applications - Electronic document file format enhancement for accessibility - Part 1: Use of ISO 32000‑1 - specifies how to use ISO 32000-1:2008 (PDF) to produce accessible electronic documents. Commonly referred to as PDF/UA, the standard defines which PDF components and usage patterns are required so documents can be reliably interpreted by people using assistive technology (screen readers, magnifiers, etc.). The standard also defines requirements for conforming files, conforming readers, and conforming assistive technology. It does not cover conversion processes, rendering implementation, storage media, or required hardware/operating systems.
Key topics and technical requirements
ISO 14289-1 organizes accessibility requirements across file structure, content, and interoperability. Major technical topics include:
- Conformance model: requirements for conforming files, readers, and assistive technology (clauses 6–9).
- File format requirements: obligations on text, graphics, headings, lists, tables, mathematical expressions, page headers/footers, notes, optional content, embedded files, and article threads (clause 7).
- Navigation and metadata: structured navigation, document language declaration, and accessibility metadata to support discovery and use.
- Annotations and actions: handling annotations, links and interactive actions so they are accessible (clauses 7.18–7.19).
- Fonts and digital signatures: guidance to ensure text is readable and signatures do not impede access (clauses 7.21, 7.13).
- Security and optional content: rules to avoid rendering barriers from security settings or hidden layers.
- Conforming reader and AT behavior: minimum behavior expectations for PDF viewers and assistive technology to present semantic structure and reading order (clause 8–9).

Practical applications and who uses it
ISO 14289-1 is used to create, validate and consume accessible PDF documents across sectors:
- Document creators and publishers produce compliant PDFs for web, government, education, healthcare and archives.
- Software vendors (PDF authoring, conversion, validation and reader apps) implement PDF/UA features to ensure compatibility with screen readers and other assistive technology.
- Accessibility specialists and QA teams use PDF/UA as the benchmark for testing and certification of accessible documents.
- Procurement and policy makers reference PDF/UA in accessibility requirements for contracts and public-sector publishing.
- Libraries and archives apply PDF/UA when preserving digital content intended to remain accessible.
Related standards
- ISO 32000-1:2008 (PDF specification) - normative foundation for PDF/UA.
- ISO 19005 (PDF/A) - archival PDF profile (can be used alongside PDF/UA).
- ISO 15930 (PDF/X) - printing and exchange profiles.
By following ISO 14289-1:2014 (PDF/UA-1), organizations can produce semantically rich, machine-readable PDFs that improve accessibility and interoperability with assistive technologies.
