Accessibility and usability of the built environment - Technical performance criteria and specifications

This document has been developed to support EN 17210, “Accessibility and usability of the built environment – Functional requirements”. This document provides and exemplifies technical performance criteria and specifications for an accessible and usable built environment, following the Design for All/Universal design principles. The document specifies what is necessary to align with these principles which will facilitate equitable and safe use for a wide range of users.
The technical performance criteria and specifications are applicable across the full spectrum of the built environment and can be used as criteria for awarding public contracts (in support of the Public Procurement Directives).
These technical performance criteria and specifications are specifically applicable to the design, construction, refurbishment or adaptation, and maintenance of public or public-use environments including external areas.
Alternatively, national standards and regulations may determine the technical performance criteria and specifications to fulfil the functional requirements of EN 17210.
NOTE 1     Design for All and Universal Design share a similar inclusive design philosophy. Universal Design means the design of products, environments, programmes and services to be usable by all people, to the greatest extent possible, without the need for adaptation or specialized design. Universal Design shall not exclude assistive devices for particular groups of persons with disabilities where this is needed (UN CRPD).
NOTE 2     Terms such as "design for all", "universal design", "accessible design", "barrier-free design", "inclusive design" and "transgenerational design" are often used interchangeably with the same meaning.

Barrierefreiheit und Nutzbarkeit der gebauten Umgebung - Technische Leistungskriterien und Anforderungen

Accessibilité et utilisabilité de l’environnement bâti - Critères et spécifications de performance technique

Le présent document a été élaboré pour venir à l’appui de l’EN 17210, « Accessibilité et utilisabilité de l’environnement bâti – Exigences fonctionnelles ». Il fournit des exemples illustrant les critères et spécifications de performance technique pour un environnement bâti accessible et utilisable selon les principes de conception universelle/conception pour tous. Le présent document spécifie les mesures nécessaires à mettre en oeuvre afin de respecter ces principes, qui ont pour vocation de faciliter l’utilisation sûre et équitable de l’environnement bâti pour un large éventail d’utilisateurs.
Les critères et spécifications de performance technique sont applicables à l’ensemble du spectre de l’environnement bâti et peuvent être utilisés comme critères pour la passation de marchés publics (à l’appui des directives relatives aux marchés publics).
Ces critères et spécifications de performance technique s’appliquent en particulier à la conception, à la construction, à la réhabilitation et à la maintenance d’environnements publics ou à usage public, y compris les espaces extérieurs.
Des normes nationales et des réglementations peuvent aussi déterminer les critères et spécifications de performance technique permettant de satisfaire aux exigences fonctionnelles de l’EN 17210.
NOTE 1 La « conception pour tous » et la « conception universelle » partagent une philosophie de conception inclusive analogue. La conception universelle désigne la conception de produits, d’environnements, de programmes et de services destinés à être utilisés par tous, dans la mesure du possible, sans nécessiter d’adaptations ni de conception spécifique. La conception universelle n’exclut pas les aides techniques destinées à certains groupes particuliers ou personnes handicapées qui en ont besoin (CDPH de l’ONU).
NOTE 2 Les termes tels que « conception pour tous », « conception universelle », « conception accessible », « aménagement à accès facile », « conception inclusive » et « conception transgénérationnelle » sont souvent utilisés indifféremment, mais dans le même sens.

Introduction
This document exemplifies the technical performance criteria and specifications to fulfil the functional
requirements given in the European Standard EN 17210. It demonstrates a proposal, or proposals, to
achieve the EN requirements and recommendations, drawing on performance criteria and specifications
given in International Standard ISO 21542, where these exist and/or with examples from other standards
and guidance documents, where relevant.
Alternatively, national standards or regulations may be used to determine the technical performance
criteria and specifications to fulfil the functional requirements of the EN 17210.
Another CEN-CENELEC Technical Report (CEN/TR 17622) will detail the assessment of conformity to the
functional requirements given in the European Standard EN 17210.
This document is intended to be read alongside EN 17210. The structure in CEN/TR 17621 follows the
EN structure, listing the equivalent headings, clauses and bullet points (a), b), c) etc.) and providing a
way, or ways, to achieve the functional requirements and recommendations.
Where there are no technical criteria related to the EN clause / sub-clause, such as the Rationale, this is
stated rather than leaving this blank.
Technical performance criteria and specifications from ISO 21542:2011 are used in the CEN/TR 17621
as the main source of information, and this is not referenced as the source each time, as this would be
repetitive. When the source is ISO 21542:2021 (Enquiry version) we include this source in brackets, and
other sources are also referenced.
Other sources are used where these have been identified as providing information not covered in
ISO 21542 or useful supplementary information.
Additional sources include:
— EN 16584-1, Railway applications – Design for PRM use – General requirements – Part 1: Contrast,
— EN 16584-2, Railway applications – Design for PRM use – General requirements – Part 2: Information.
— EN 16584-3, Railway applications – Design for PRM use – General requirements – Part 3: Optical and
friction characters.
— EN 16587, Railway applications – Design for PRM use –Requirements for obstacle free routes for
infrastructure,
— Other specific ENs and product related ENs,
— National standards,
— Guidance on a specific matter.

1 Scope
This document has been developed to support EN 17210, “Accessibility and usability of the built
environment – Functional requirements”. This document provides and exemplifies technical
performance criteria and specifications for an accessible and usable built environment, following the
Design for All/Universal design principles. The document specifies what is necessary to align with these
principles which will facilitate equitable and safe use for a wide range of users.
The technical performance criteria and specifications are applicable across the full spectrum of the built
environment and can be used as criteria for awarding public contracts (in support of the Public
Procurement Directives).
These technical performance criteria and specifications are specifically applicable to the design,
construction, refurbishment or adaptation, and maintenance of public or public-use environments
including external areas.
Alternatively, national standards and regulations can determine the technical performance criteria and
specifications to fulfil the functional requirements of EN 17210.
NOTE 1 Design for All and Universal Design share a similar inclusive design philosophy. Universal Design means
the design of products, environments, programmes and services to be usable by all people, to the greatest extent
possible, without the need for adaptation or specialized design. Universal Design does not exclude assistive devices
for particular groups of persons with disabilities where this is needed (UN CRPD).
NOTE 2 Terms such as "design for all", "universal design", "accessible design", "barrier-free design", "inclusive
design" and "transgenerational design" are often used interchangeably with the same meaning.

Introduction
This document exemplifies the technical performance criteria and specifications to fulfil the functional
requirements given in the European Standard EN 17210. It demonstrates a proposal, or proposals, to
achieve the EN requirements and recommendations, drawing on performance criteria and specifications
given in International Standard ISO 21542, where these exist and/or with examples from other standards
and guidance documents, where relevant.
Alternatively, national standards or regulations may be used to determine the technical performance
criteria and specifications to fulfil the functional requirements of the EN 17210.
Another CEN-CENELEC Technical Report (FprCEN/TR 17622) will detail the assessment of conformity
to the functional requirements given in the European Standard EN 17210.
This document is intended to be read alongside EN 17210. The structure in FprCEN/TR 17621 follows
the EN structure, listing the equivalent headings, clauses and bullet points (a), b), c) etc.) and providing a
way, or ways, to achieve the functional requirements and recommendations.
Where there are no technical criteria related to the EN clause / sub-clause, such as the Rationale, this is
stated rather than leaving this blank.
Technical performance criteria and specifications from ISO 21542:2011 are used in the
FprCEN/TR 17621 as the main source of information, and this is not referenced as the source each time,
as this would be repetitive. When the source is ISO/DIS 21542:2020 (Enquiry version) we include this
source in brackets, and other sources are also referenced.
Other sources are used where these have been identified as providing information not covered in
ISO 21542 or useful supplementary information.
Additional sources include:
 EN 16584-1, Railway applications – Design for PRM use – General requirements – Part 1: Contrast,
 EN 16584-2, Railway applications – Design for PRM use – General requirements – Part 2: Information.
 EN 16584-3, Railway applications – Design for PRM use – General requirements – Part 3: Optical and
friction characters.
 EN 16587, Railway applications – Design for PRM use –Requirements for obstacle free routes for
infrastructure,
 Other specific ENs and product related ENs,
 National standards,
 Guidance on a specific matter.

1 Scope
This document has been developed to support EN 17210, “Accessibility and usability of the built
environment – Functional requirements”. This document provides and exemplifies technical
performance criteria and specifications for an accessible and usable built environment, following the
Design for All/Universal design principles. The document specifies what is necessary to align with these
principles which will facilitate equitable and safe use for a wide range of users.
The technical performance criteria and specifications are applicable across the full spectrum of the built
environment and can be used as criteria for awarding public contracts (in support of the Public
Procurement Directives).
These technical performance criteria and specifications are specifically applicable to the design,
construction, refurbishment or adaptation, and maintenance of public or public-use environments
including external areas.
Alternatively, national standards and regulations may determine the technical performance criteria and
specifications to fulfil the functional requirements of the EN 17210.
NOTE 1  Design for All and Universal Design share a similar inclusive design philosophy. Universal Design means
the design of products, environments, programmes and services to be usable by all people, to the greatest extent
possible, without the need for adaptation or specialized design. Universal Design shall not exclude assistive devices
for particular groups of persons with disabilities where this is needed (UN CRPD).
NOTE 2  Terms such as "design for all", "universal design", "accessible design", "barrier-free design", "inclusive
design" and "transgenerational design" are often used interchangeably with the same meaning.
