SIST EN 301549:2021

Accessibility requirements for ICT products and services

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 is intended to be used with Web based technologies, non-web technologies and hybrids that use both. It covers both software and hardware as well as services. It is intended for use by both providers and procurers, but it is expected that it will also be of use to many others as well.
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.

Exigences d’accessibilité pour les produits et services TIC

Le présent document définit les exigences d’accessibilité fonctionnelle applicables aux produits et services TIC et
fournit une description des modes opératoires d’essai et de la méthodologie d’évaluation pour chaque exigence
d’accessibilité sous une forme adaptée à une utilisation dans le cadre des marchés publics en Europe. Le présent
document est destiné à être utilisé avec les technologies Web, les technologies non Web et les hybrides utilisant les
deux. Il couvre à la fois le logiciel et le matériel ainsi que les services. Il est destiné à être utilisé à la fois par les
fournisseurs et les acheteurs, mais il est attendu qu’il sera également utilisé par beaucoup d’autres.
La relation entre le présent document et les exigences essentielles de la Directive 2016/2102 relative à l’accessibilité des
sites Internet et des applications mobiles des organismes du secteur public [i.28] est indiquée dans l’Annexe A.
Le présent document contient les exigences fonctionnelles nécessaires et fournit un document de référence permettant,
si les procédures sont suivies par les différents acteurs, d’obtenir des résultats d’essais similaires et une interprétation
claire de ces résultats. Les descriptions des essais et la méthodologie d’évaluation figurant dans le présent document
sont élaborées à un niveau de détail conforme à l’ISO/IEC 17007:2009 [i.14], afin que les essais de conformité puissent
aboutir à des résultats concluants.
