EN 301 549

EN 301 549 is the European harmonised standard titled Accessibility requirements for ICT products and services. It is the single reference Europe points to when it needs to say, in concrete technical terms, what “accessible” means — not just for websites, but for the whole range of information and communications technology a public body or business might buy, build, or offer.

What it is

The standard is maintained jointly by the three European standards organisations — ETSI, CEN, and CENELEC. Rather than invent a fresh set of web rules, it gathers existing best practice into one testable document and adopts WCAG wholesale for its web and content requirements. Its real value is breadth: it turns a broad legal promise of accessibility into specific, checkable requirements that procurement teams, auditors, and suppliers can all work from.

Who must comply

EN 301 549 is the technical standard behind two pieces of European law. Through the Web Accessibility Directive it binds public sector bodies — government, public services, and the organisations that act for them — whose websites and mobile apps must meet it. Through the European Accessibility Act it reaches the private sector: conforming to EN 301 549 gives a presumption of conformance for the products and services the Act covers. In short, if you sell to or operate within the EU market, this is the standard your accessibility is measured against.

Relationship to WCAG

For anything web-facing, EN 301 549 does not write its own success criteria — it incorporates WCAG at Level A and Level AA. Version 3.2.1 of the standard references WCAG 2.1 AA; a newer revision aligns to WCAG 2.2. That means meeting WCAG A and AA satisfies the web portion of EN 301 549 directly. The standard then layers additional requirements on top for the things WCAG does not cover.

Key points

  • Harmonised European standard for the accessibility of ICT products and services.
  • Maintained jointly by ETSI, CEN, and CENELEC.
  • Adopts WCAG Level A and AA for web and content (3.2.1 references WCAG 2.1 AA; a newer revision aligns to 2.2).
  • Goes beyond web pages to non-web documents, software, hardware, biometrics, and support services.
  • Binds the public sector via the EU Web Accessibility Directive.
  • Provides presumed conformance for the private sector under the European Accessibility Act.

Build the practical skills behind this standard, and see the law it underpins:

  • Learn — the hands-on lessons that teach the WCAG techniques EN 301 549 incorporates.
  • European Accessibility Act — the private-sector law for which EN 301 549 is the presumed-conformance route.

Part of a bigger picture

EN 301 549 is one of several laws and standards covered in the Standards overview. They differ in jurisdiction and scope, but they share the same technical core: WCAG. Get WCAG right and you are most of the way to meeting all of them.
