Tactile paving surface indicators produced from concrete, clay and stone
This document specifies the method of measurement and acceptance criteria for the dimensions for surface profile features and patterns for the surface of pedestrian paving units, used to convey information for visually impaired people. It applies to paving units made of concrete, clay and stone where the tactile profiles are monolithic with the unit.
The surface profiles are intended to be applied to units manufactured to EN 1338, EN 1339, EN 1341, and EN 1344 which can be square or rectangular as specified by the designer.
It does not specify dimensions of a single tactile paving layout or profile but proposes ranges within which these dimensions should fall. Default dimensions are given in the absence of a national requirement.
This document proposes methods of measurement of profiles, light reflectance and colour but does not specify requirements for these characteristics. These properties will be decided by the designer taking into account the regulations, codes of practice, and guidance in the place of use of the units.
It does not specify material characteristics.
Taktile Bodenindikatoren gefertigt aus Beton, Ton und Stein
Dieses Dokument legt das Messverfahren und die Akzeptanzkriterien für die Maße der Elemente von Oberflächenprofilen und der Oberflächenmuster von Profilplatten für Fußgängerbereiche fest, die zur Übermittlung von Informationen an sehbehinderte Menschen verwendet werden. Es gilt für Profilplatten, die aus Beton, Ton und Stein gefertigt sind und bei denen die taktilen Profile monolithisch mit der Platte verbunden sind.
Die Oberflächenprofile sind für Platten vorgesehen, die nach EN 1338, EN 1339, EN 1341 und EN 1344 gefertigt werden und je nach Vorgabe des Gestalters quadratisch oder rechteckig sein können.
Es werden keine Maße von Layout oder Profil einer einzelnen taktilen Profilplatte festgelegt, sondern es werden Bereiche vorgeschlagen, in denen diese Maße liegen sollten. Beim Fehlen einer nationalen Anforderung werden Standardmaße angegeben.
Dieses Dokument gibt Verfahren zur Messung von Profilen, Lichtreflexionswert und Farbe an, legt aber keine Anforderungen für diese Merkmale fest. Diese Eigenschaften werden vom Gestalter unter Berücksichtigung der am Verwendungsort der Platten geltenden Vorschriften, Regeln der Technik und Leitlinien festgelegt.
Es werden keine Materialkennwerte festgelegt.

European foreword
This document (FprCEN/TS 15209:2019) has been prepared by Technical Committee CEN/TC 178
“Paving units and kerbs”, the secretariat of which is held by BSI.This document is currently submitted to the Vote on TS.
This document will supersede CEN/TS 15209:2008.
The following changes have been made in CEN/TS 15209:2008 compared with FprCEN/TS 15209:2019:
a) IntroductionThe introduction has been extended to cover the measurement of light reflectance values of units to
enable designers to implement adequate visual contrast between tactile units and adjacent surfaces in
accordance with standards in the place of use.This introduction confirms that the given default values should be used where no standards exist.
b) ScopeThe scope covers the method and acceptance criteria for the dimensions of the surface and profile features
for tactile paving units. It does not specify requirements for profile and dimensions of a single tactile
paving unit but proposes ranges within which these dimensions should fall. These properties should be
decided by the designer taking into account the regulations, codes of practice, and guidance in the place of
use of the units.c) Definitions
Generally updated to include light reflectance value, visual contrast and designer.
Requirements for tactile paving surface indicators.Dimensions and tolerances restated. Consolidated layouts and profiles added with ranges and default
values given.Light reflectance value (LRV) of paving surface indicators.
Methods for determining light reflectance values defined.
d) Annex A
Use of the value declared in place of use replaces Guide to the various specifications of tactile surfaces in a
number of European countries.e) Annex B
Guide to the preferred dimensions for tactile paving surface indicator profiles for use in a number of
European countries deleted and replaced with old Annex C Measurement of the dimensions of a single
tactile paving unit.f) Annex C

Introduction
The nature of visual impairment varies considerably among individuals. Generally, the result of different
eye conditions will lead to the following types of impairment:— a limited field of vision, being unable to see to the sides or up and down;
— some loss of central vision limiting the ability to see fine detail;
— acute short‐sightedness, seeing the world as a continuous blur;
— uncontrollable oscillations of the eyeball leading to an inability to see objects clearly;
— night blindness, a sensitivity to light and a tendency to be dazzled by glare.Visually impaired people detect information about the environment by the use of non‐visual features, for
example, audible and tactile features. A loss of sight is not accompanied by an increase in the effectiveness
of other non‐visual senses. However, visually impaired people generally place more emphasis on
information received via other senses, for example the sense of touch.The use of tactile information: when moving around the pedestrian environment, visually impaired
people, using a range of mobility equipment including the long cane, will actively seek and make use of
tactile paving surface information, particularly detectable contrasts in surface texture.
The ability to detect contrasts in texture underfoot varies from one individual to another. For example,
older visually impaired people and people who have lost their sight through certain medical conditions,
such as diabetes, can have reduced sensitivity in their feet.It is important that tactile warnings of potential hazards, e.g. a road crossing or a stair, are rigorous
enough to be detectable by most people but without constituting a trip hazard or causing extreme
discomfort.Considering the walking speed and the length of one step by a visually impaired pedestrian, the width of
any warning surface is a critical parameter.Visually impaired people who have some residual vision will make use of the luminance contrast between
surfaces for orientation and guidance, in addition to tactile information. To provide visual and tactile
guidance as well as to accentuate the presence of hazards and amenities, luminance contrast between
tactile paving units and the adjacent surface needs to be considered by designers, planners, engineers and
others involved in the design of the built and pedestrian environments.Whereas this standard covers the measurement of light reflectance values of individual units, it does not
cover the required criteria necessary to enable designers to implement adequate luminance contrast since
this relies on the difference between adjacent surfaces, which do not both need to be tactile surfaces.
However, manufacturers should be aware of this issue in considering the range of colour and tones they
provide in their tactile products. Methods for measurement of light reflectance values and the colour of
individual units is proposed in this Standard.This standard is not intended to set requirements for the layout of tactile paving units, but to allow
manufacturers to place their products on the market with a CE marking. It is intended that layouts and the
specific layout of individual tactile profiles within units will be set locally taking into account regulations,
Codes of Practice, standards and guidance at the place of use and be within the ranges given in this
standard. Where no local guidance is available default values are given which should be used.
