EN 301 549
Definition
Its full title is 'Accessibility requirements for ICT products and services', and it is published jointly by ETSI, CEN and CENELEC, the three European standards bodies. It is broader than a web standard: separate clauses cover hardware, software, documentation and support services, two-way communication, and non-web documents. Clause 9 handles web content and maps criterion for criterion onto WCAG at levels A and AA, clause 10 applies the same requirements to documents that are not web pages, which is where a PDF or a spreadsheet lands, and clause 11 covers software and mobile apps. The version cited under the Web Accessibility Directive, Directive (EU) 2016/2102, is V3.2.1, published in March 2021, which adopts WCAG 2.1 level AA. A 4.x revision has been prepared to sit alongside newer EU legislation, so check ETSI's current publication rather than assuming a version number. This page is general information and not legal advice.
Why It Matters
It is the document that turns an accessibility principle into a procurement checkbox. Public sector bodies across the EU — councils, universities, health services, ministries — are required to make their websites and mobile apps accessible, and this is the standard their tender documents name, which means a supplier who cannot answer against its clauses is often filtered out before anyone reads the pitch. The clause 10 requirement for non-web documents catches organisations off guard more than anything else, because it applies to every PDF form, report and agenda they publish, not just the pages around them. Meeting a harmonised standard also carries a presumption of conformity with the legislation it supports, which is a useful place to stand. The European Accessibility Act has pushed the same standard toward private-sector products and services as well.
How It Works
Conformance is assessed clause by clause, and clause 9 will already be familiar to anyone who has tested against WCAG, since the criteria are identical in substance. Beyond that come requirements with no web equivalent: closed functionality where no assistive technology can be attached, such as a ticket machine; biometric identification alternatives; and the rule that documentation and support services must themselves be accessible. Annex A maps the clauses to the Web Accessibility Directive, and Annex C gives the specific test procedures, so an evaluation follows a defined method rather than an opinion. Suppliers usually report results in the EN 301 549 edition of a VPAT, or in the INT edition that also covers WCAG and Revised Section 508. Public bodies additionally publish an accessibility statement in the format the Directive sets out, naming known failures and offering a feedback route.
Real-World Example
A translation agency bidding for a city council contract is asked to state conformance with EN 301 549 V3.2.1. Their website passes on clause 9, but the 6 MB rate card they send every client is a scanned, untagged PDF, which fails clause 10 outright. Re-exporting it from the original document with structure tags and republishing it at rates.99helpers.site made the same file readable by assistive technology and searchable at the same time. 99helpers hosts whatever you upload without altering it, so the remediation happened in the authoring tool and the link stayed the same.
Common Mistakes
- ✕Reading it as a web-only standard — clause 10 covers the PDFs and office documents an organisation publishes, and that is where most public-sector failures are found
- ✕Quoting the standard with no version number — V3.2.1 adopts WCAG 2.1 level AA, and a newer revision changes what you are claiming
- ✕Assuming a WCAG-only conformance report answers a European tender — the buyer needs the clauses their own obligations are written against, not an approximate equivalent
Related Terms
European Accessibility Act
The European Accessibility Act is EU legislation that extends accessibility requirements from the public sector to a defined list of products and services sold to consumers in the EU. It has applied since 28 June 2025.
WCAG
WCAG, the Web Content Accessibility Guidelines, is the W3C standard that defines what accessible web content is. Its success criteria at Levels A, AA and AAA are what accessibility law and procurement point to.
VPAT
A VPAT, or Voluntary Product Accessibility Template, is the form a vendor fills in to describe how far a product meets a named accessibility standard. The completed document is properly called an Accessibility Conformance Report.
ADA Compliance
ADA compliance refers to meeting the Americans with Disabilities Act as it has been applied to websites and digital services. The statute names no web standard, so the picture is built from regulation and case law rather than from a single document.
GDPR
The European Union's General Data Protection Regulation, in force since 25 May 2018, governing how personal data about people in the EU may be collected and used. The UK keeps a near-identical version in its own law.
