European Commission has published a built environment standard for accessibility. It describes basic, common minimum functional requirements using universal design principles. The accessibility and usability requirements relate to the design, construction, refurbishment and maintenance of indoor and outdoor environments. This one is for standards gurus.
The standard was based on consensus between relevant stakeholders. The CEN-CENELEC webpage has more detail about the standard and what it contains. The document is titled, EN 17210:2021 Accessibility and usability of the built environment – Functional requirements.
The “CEN-CENELEC Protocol on accessibility following a Design for All approach in standardization” outlines the procedure to help technical bodies decide whether accessibility, with a Design for All approach, should be addressed when developing or revising a standardization deliverable.
The European Committee for Standardization is one of three European Standardization Organizations (together with CENELEC and ETSI) that have been officially recognized by the European Union and by the European Free Trade Association (EFTA) as being responsible for developing and defining voluntary standards at European level.
The websites are not the easiest to navigate but there is more information if you care to start searching their standards.
