EN 301 549 is a European standard that specifies accessibility requirements for ICT (Information and Communication Technology) products and services. It is published jointly by ETSI (European Telecommunications Standards Institute), CEN (European Committee for Standardization), and CENELEC (European Committee for Electrotechnical Standardization).
The standard covers web content, mobile applications, desktop software, hardware devices, documentation, and support services. For web content and digital interfaces, EN 301 549 incorporates WCAG 2.1 Level AA in its entirety and adds ICT-specific requirements that WCAG alone does not address.
Why it matters
EN 301 549 is the technical bridge between the European Accessibility Act and actual implementation. The EAA sets the legal obligation. EN 301 549 defines what compliance looks like in practice. Any organization subject to the EAA must meet EN 301 549 requirements for its covered products and services.
What it covers beyond WCAG
While WCAG focuses on web content, EN 301 549 extends accessibility requirements to:
- Hardware: physical controls, displays, audio output on devices, kiosks, and terminals.
- Software: desktop and mobile applications, not just web content.
- Documentation: user guides, technical specifications, and support materials must be accessible.
- Support services: help desks and customer support channels must accommodate users with disabilities.
- Two-way voice communication: real-time text, caller ID, and emergency services access.
- Video: real-time captions, audio description, and sign language support.
EN 301 549 and TTS
For TTS implementations, EN 301 549 inherits the six WCAG criteria that apply to audio content (audio control, text alternatives, keyboard access, ARIA roles, language declaration) and adds requirements for hardware devices that must provide TTS output as an accessibility option. Self-service terminals, kiosks, and consumer electronics with digital interfaces must support synthesized speech output.

How does EN 301 549 relate to WCAG?
For web content and digital interfaces, EN 301 549 maps directly to WCAG 2.1 Level AA. It incorporates all WCAG 2.1 AA success criteria and adds additional requirements specific to non-web ICT such as hardware, software, and documentation.
How does EN 301 549 relate to the EAA?
The European Accessibility Act references EN 301 549 as the technical standard that defines how to meet its accessibility requirements. Compliance with EN 301 549 demonstrates compliance with the EAA's technical obligations.
What version of EN 301 549 is current?
The current version is V3.2.1, published in March 2021. Future updates are expected to incorporate WCAG 2.2 requirements and may add TTS-specific provisions.
