European foreword
This document (prEN 1463-3:2020) has been prepared by Technical Committee CEN/TC 226 “Road
equipment”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association, and supports basic work requirements of
Regulation (EU) Nr. 305/2011.
For relationship with Regulation (EU) 305/2011, see informative Annexe ZA, which is an integral part of
this document.
Introduction
The development of this document has been prompted by the appearance of road studs which contain an
active element which emits light instead of, or as well as, reflecting light from headlights.
1 Scope
This document specifies the initial and the retained performance requirements and laboratory test
methods for solar powered, hardwired and communicating active road studs intended for use as
permanent road marking materials.
In accordance with Low Voltage Directive 2014/35/EU, product characteristic electrical safety is
applicable only to those active road studs which are designed with voltage rating between 50 and 1 000 V
for alternating current and between 75 and 1 500 V for direct current. Voltage ratings refer to the voltage
of the electrical input or output, not to voltages that may appear inside the equipment.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 1463-1 and the following apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— IEC Electropedia: available at http://www.electropedia.org/
— ISO Online browsing platform: available at http://www.iso.org/obp
3.1
active road stud
horizontal guiding device that is fixed to the surface of a road and emits light in order to warn, guide or
inform road users
Note 1 to entry: An active road stud provides a light output by itself, while a retroreflective road stud provides
retroreflected light when illuminated by the headlamps of a vehicle. Retroreflective road studs are covered by
EN 1463-1:2009.
Note 2 to entry: An active road stud can be fitted with a retroreflector so that it provides a light output both
directly and by retroreflection.
Note 3 to entry: An active road stud can be self-contained in the sense that it incorporates all light generation
means and does not rely on an external source of light or power. Light generation means include one or more light
sources, typically LED’s, and a power supply, typically a battery that is charged by a solar panel integrated in the
upper surface of the road stud.
Note 4 to entry: As opposed to a self-contained active road stud, an active road stud can also be hardwired in the
sense that it receives light through fibre optics or power through a wire. Means to feed light or power are not
considered in this document.
Note 5 to entry: An active road stud can have one or more luminous faces intended for emitting light in one or
more traffic directions.
Note 6 to entry: An active road stud can emit light that appears constant to the human eye or be flashing at a low
frequency. The emitted light can be any of the colours white, yellow/amber, red, green or blue.
Note 7 to entry: As with a retroreflective road stud, an active road stud can be fixed to a road surface by being
bonded to, entered within or embedded within the road surface. Additionally, an active road stud can be depressible
or non-depressible.
3.2
luminance expressed as light output (cd)
for the purpose of this document the term luminance expressed as light output (cd) is used to describe
luminous intensity measured in cd
3.3
chromaticity co-ordinates (x,y)
chromaticity coordinates of the colours are defined in accordance with the CIE 1931 Standard
Colorimetric 2° Observer as referenced in CIE 15
Note 1 to entry: For the purpose of this standard colours white, red, yellow/amber, orange, green and blue are
defined using chromaticity coordinates of corner points of chromaticity regions for emitted radiation as specified
in Table 1 and outlined in Figure 1.

The declared values shall be tested in accordance with 5.1.
4.1.3 Chromaticity coordinates (x,y) (for day and night-time visibility)
When tested in accordance with 5.2, the emitted radiation of each luminous face of an active road stud
shall be described by measured chromaticity coordinates (x,y) and declared as either of the colours white,
red, yellow/amber, orange, green or blue.
Chromaticity coordinates (x,y) of retro-reflected light (only for retroflecting active road studs) are
provided in EN 1463-1:2009, 5.3.
4.2 Light output frequency
Active road studs can emit light in pulses/flashes. The lowest flashing frequency of the light emitted is
determined as the number of pulses per minute and expressed in Hz. The lowest flashing frequency of
the light emitted shall be measured in accordance with 5.3.
4.3 Electrical safety
Active road studs with input or output voltages between 50 and 1 000 V for alternating current and
between 75 and 1 500 V for direct current shall conform to EN 60598-1:2015 when tested in accordance
with EN 60598-2-13:2006.
4.4 Electromagnetic compatibility

4.5 Ingress protection (IP code)
Protection against dust and water shall be declared in accordance with EN 60529 and tested in
accordance with 5.4.
4.6 Durability on road trials
The durability of retro-reflectivity for night-time visibility of retroflecting active road studs is tested after
road trials in accordance with EN 1463-2. During this test, the retroflecting active road studs need not
have any light output.
The durability of the following characteristics of active road studs shall be tested after a road trial in
accordance with 5.5:
— Luminance (for day and night-time visibility) expressed as Light output (Cd) declared in accordance
with 4.1.2 in reference direction.
— Chromaticity coordinates (x,y), for night-time declared in accordance with 4.1.3.
— Light output frequency (Hz declared in accordance with 4.2.
The characteristics are measured both before and after exposure to the road trial.
5 Testing, assessment and sampling methods
5.1 Test of light output (luminous intensity cd)
A luminous face of an active road stud is assigned a reference centre and a reference direction, which
points against the traffic direction intended for that luminous face.
The active road stud is mounted in a goniometer such as shown in Figure 2, with the reference centre in
the rotation centre of the goniometer and the reference direction pointing along the optical bench
towards a photometer.
The photometer is placed at such a distance D between the locations 1 and 4 in Figure 2 that neither the
luminous face nor the receptive surface of the photometer exceeds 10’ (minutes of arc) as seen from that
distance.
Key
1 rotation centre of goniometer
2 horizontal angle
3 vertical angle
4 photometer
Figure 2 — Goniometer and optical bench with a photometer
The goniometer is placed in a darkened room with an ambient temperature of 25 °C. If operated on
integral storage, the active road stud is fully charged in accordance with the manufacturer’s instructions.
If hardwired, the active road stud is supplied in accordance with the manufacturer’s instructions.
The light output (luminous intensity cd) in a particular direction is obtained by this procedure:
a) the desired horizontal and vertical angles from reference direction are set;
b) the illuminance E in lux (lx) with the active road stud turned off is recorded;
c) the illuminance E in lux (lx) with the active road stud turned on is recorded;
d) the light output (luminous intensity cd) in candela (cd) is determined by I = (E - E ) × D .
An initial warm up time in accordance with the manufacturer’s instructions shall be allowed in order to
obtain stable measurements.
5.2 Test of Chromaticity coordinates (x,y) (for day and night-time visibility)
The set up for test of chromaticity of the emitted light is done in the same way as for the test of the light
output (luminous intensity cd) as described in 5.1 but using a colourimeter instead of a photometer.
The chromaticity coordinates are obtained by this procedure:
a) the reference direction is set;
b) the chromaticity coordinates are recorded;
An initial warm up time in accordance with the manufacturer’s instructions shall be allowed in order to
obtain stable measurements
5.3 Test of light output flashing frequency
Flashing frequency shall be measured using a suitable timing device to determine the total number of
complete on/off cycles in one minute.
5.4 Ingress protection (IP code)
Declarations of protection against dust and water shall be tested in accordance with EN 60529:1991,
Clause 13 and 14.
5.5 Test of durability on road trials
The durability of the following characteristics is tested on road trials:
— Luminance (for day and night-time visibility) expressed as Light output (cd) tested in accordance
with 5.1. Only reference direction is used for testing.
— Chromaticity coordinates (x,y), for night-time visibility tested in accordance with 5.2.
— Light output flashing frequency (Hz) tested in accordance with 5.3.
This test needs to involve only 10 active road studs emitting white light, and only measurement of the
light output and the chromaticity coordinates in reference direction.
Application of active road studs on test site shall be in accordance with the instructions of the
manufacturer. During this test, the active road studs need not have any light output.
NOTE 1 For example, in case of hard-wired active road studs it is not necessary to power and operate the road
studs during the road trial.
The volume of traffic shall be such as to ensure that at least three active road studs are exposed to
minimum 200 000 wheel passages.
A road trial shall include at least one full climatic cycle of one year.
NOTE 2 Special requirements (e.g. snow clearance, studded tyres) considered indispensable for some countries
or special applications, may be taken into account by the participating parties for the selection of the test site and
recorded in the general report for the test site.
6 Assessment and verification of constancy of performance – AVCP
6.1 General
The compliance of active road studs with the requirements of this standard and with the performances
declared by the manufacturer in the DoP shall be demonstrated by:
— determination of the product type;
— factory production control by the manufacturer, including product assessment.
The manufacturer shall always retain the overall control and shall have the necessary means to take
responsibility for the conformity of the product with its declared performance(s).
6.2 Type testing
6.2.1 General
All performances related to characteristics included in this standard shall be determined when the
manufacturer intends to declare the respective performances unless the standard gives provisions for
declaring them without performing tests. (e.g. use of previously existing data, CWFT and conventionally
accepted performance).
Assessment previously performed in accordance with the provisions of this standard, may be taken into
account provided that they were made to the same or a more rigorous test method, under the same AVCP
system on the same product or products of similar design, construction and functionality, such that the
results are applicable to the product in question.
NOTE 1 Same AVCP system means testing by an independent third party, under the responsibility of a notified
