The present document specifies the functional accessibility requirements applicable to ICT products and services, together with a description of the test procedures and evaluation methodology for each accessibility requirement in a form that is suitable for use in public procurement within Europe. The present document might be useful for other purposes such as procurement in the private sector.
The relationship between the present document and the essential requirements of Directive 2016/2102 on the
accessibility of the websites and mobile applications of public sector bodies is given in Annex A.
The present document contains the necessary functional requirements and provides a reference document such that if procedures are followed by different actors, the results of testing are similar and the interpretation of those results is clear. The test descriptions and evaluation methodology included in the present document are elaborated to a level of detail compliant with ISO/IEC 17007:2009, so that conformance testing can give conclusive results.
All clauses except those in clause 12, related to documentation and support services, are self-scoping. This means they are introduced with the phrase ‘Where ICT ‘. Compliance is achieved either when the pre-condition is true and the corresponding test (in Annex C) is passed, or when the pre-condition is false (i.e. the pre-condition is not met or not valid).
NOTE 1: Compliance issues are covered in normative clause C.1.
The inherent nature of certain situations makes it impossible to make reliable and definitive statements that accessibility requirements have been met. In those situations therefore, the requirements in the present document are not applicable:
• when the product is in a failure, repair or maintenance state where the ordinary set of input or output functions are not available;
• during those parts of start-up, shutdown, and other state transitions that can be completed without user
NOTE 2: Even in the above situations, it is best practice to apply requirements in the present document wherever it is feasible and safe to do so.

Relevance to Active and Healthy Ageing: High

Older Person Specific: No

Usage / Adoption status: This document supports the Web Accessibility Act (WAD)


This document covers any ICT product or service. As ICT is a key element for communication and participation, EN 301 549 should be taken into account as a really useful standard. It reflects the consensus of all the relevant European stakeholders, represented by all the 3 ESOs (CEN, CENELEC and ETSI). It is also harmonized to a great extent with the US Section 508.
EN 301 549:2018 (v.2.1.2) is the second major revision of EN 301 549. Its purpose was mainly to support the requirements of the Web Accessibility Directive. Therefore, it has been fully harmonized with the new WCAG 2.1 of W3C, and a table to check the fulfilment of the requirements of mobile applications has been added to the former one on web sites.
The works on a new revision, v.3.1.1, have already started. This project will improve the usability of the document and will further develope some clauses.
