Clause 9 — Web

Clause 9 is the clause most people mean when they talk about “EN 301 549 for websites.” It incorporates the Web Content Accessibility Guidelines (WCAG) by reference, success criterion by success criterion.

What it covers

• Meeting Clause 9 means meeting WCAG 2.1 Level A and AA in full (V4.1.1 moves this to WCAG 2.2 AA — see the caveat below).
• Applies to websites, web applications, and web content delivered as part of a product or service — including content produced by authoring tools and content management systems.
• Covers the full set of WCAG principles: perceivable, operable, understandable, robust — text alternatives, keyboard access, colour contrast, predictable navigation, compatibility with assistive technology, and more.

Who this applies to

Public sector websites and intranets/extranets under the Web Accessibility Directive, and private-sector websites and web apps in scope of the EAA — e-commerce, banking, transport ticketing, e-books, and similar services delivered over the web.

For the fuller narrative — what's in scope, how the WCAG principles translate in practice — see the Web overview.

V4.1.1 is the newest published edition, aligned with WCAG 2.2 AA. It is not yet cited in the EU Official Journal, so V3.2.1 (WCAG 2.1 AA) remains the version with current legal effect for EAA presumption of conformity — see the timeline for the expected citation date.
