Introduction
An active road stud is a horizontal guiding device that is fixed to the surface of a road and emits light in
order to warn, guide or inform road users.
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.
An active road stud may be fitted with a retroreflector so that it provides a light output both directly
and by retroreflection.
An active road stud may 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.
As opposed to a self-contained active road stud, an active road stud may 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 standard.
An active road stud may have one or more luminous faces intended for emitting light in one or more
traffic directions.
An active road stud may emit light that appears constant to the human eye or be flashing at a low
frequency. The emitted light may be any of the colours white, yellow, orange, red, green or blue.
As with a retroreflective road stud, an active road stud may fixed to a road surface by being bonded too,
entered within or embedded within the road surface. Additionally, an active road stud may be
depressible or non-depressible. Finally, an active road stud may be intended for permanent or
temporary installation.

traffic.
If the active road stud consists of two or more parts, each replaceable part shall be removable only with
a tool recommended by the manufacturer
4.8 Dimensions
Dimensions of an active road stud are expressed by the height, width and length of that part of the
active road stud designed to be above the road surface after installation.
NOTE 1 For road studs with retroreflectors, classes of dimensions are provided in EN 1463-1:2009, 5.2.
NOTE 2 On roads where the use of studded tyres is common and for the winter maintenance, active road studs
can be installed in a milled groove so that all parts are below the road surface.
4.9 Tolerance to temperature

4.13 Daytime visibility of temporary active road studs
NOTE The daytime visibility of temporary retroreflective road studs is provided in EN 1463-1:2009, 5.4 in
terms of the chromaticity and the luminance factor of the body.
5 Testing, assessment and sampling methods
5.1 Test of luminous intensity
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.

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 manufacturers instructions.
If hardwired, the active road stud is supplied in accordance with the manufacturers instructions.
The luminous intensity in a particular direction is obtained by this procedure:

c) the illuminance E in lux (lx) with the active road stud turned on is recorded;
2
d) the luminous intensity in millicandela (mcd) is determined by I = 1 000 × (E - E ) × D .
0
A sufficient initial warm up time shall be allowed in order to obtain stable measurements.
5.2 Test of colour of emitted light
The chromaticity of the emitted light is measured in the same way as the luminous intensity, but only in
the reference direction and using a colorimeter instead of a photometer.
5.3 Test of durability in field trials
After exposure of 50 active road studs to a field trial, the following evaluations shall be carried out. The
results shall be entered into a separate road trial assessment form (RTAF) and lead to a separate
selection of 10 test active road studs.
The night time examination accounted for in EN 1463-2:2000, 5.3 shall be supplemented with an
evaluation of the light output of the active road stud. This evaluation shall be carried out at the location
prescribed for the evaluation of retroreflection, but with the headlamps turned off. If a test stud has no
visible light output at all it is non-conforming.
The number of remaining conforming active road studs is expressed by its percentage of the 50 active
road stud subjected to the field trial.
After cleaning of the luminous faces of the test studs, the luminous intensities in the reference direction
are measured in accordance with 5.1 and the arithmetic mean for the selected 10 test studs is
calculated.
The mean luminous intensity is expressed by its percentage of the mean luminous intensity in the
reference direction as declared.
5.4 Tolerance to temperature
With the active road stud placed in a climate chamber, the luminous intensity and the chromaticity shall
be measured in the reference direction at the lowest and highest ambient temperatures of the range
declared.
For both temperatures, the measured luminous intensity shall comply with the declared values, the
chromaticity shall be within the relevant box and there shall be no visible flicker.
5.5 Test of integral storage capacity
With a fully charged integral storage, the active road stud is set to operate in a mode declared by the
manufacturer without any charging from solar panels or external sources, and the number of hours in
which it operates in an acceptable manner is recorded.
NOTE Charging from solar panels can be avoided by placing the active road stud in darkness.
The operation shall be deemed not acceptable when the luminous intensity in the reference direction
falls below 80 % of the minimum value declared, the chromaticity leaves the relevant box or a visible
flicker develops.

5.6 Test of charging capacity of solar panels
The manufacturer shall provide methods to determine the states when the integral storage is empty
and fully charged.
With an empty integral storage and in the off state, the active road stud is illuminated by a light source
with a spectral emission in accordance with standard illuminant D65 as defined in EN ISO 11664-2. The
charge is to be applied in one continuous action until the integral storage is fully charged.

The irradiance on the plane of the active road stud I (W⋅m ) and the duration expressed in the number
of hours N it takes to provide a full charge of the integral storage is recorded. The charging capacity is
−2
expressed by the radiant exposure I × N (W⋅h⋅m ).
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
product certification body.
For the purposes of assessment, the manufacturer's products may be grouped into families, where it is
considered that the results for one or more characteristics from any one product within the family are
representative for that same characteristics for all products within that same family
Products may be grouped in different families for different characteristics.
Reference to the assessment method standards should be made to allow the selection of a suitable
representative sample.
In addition, the determination of the product type shall be performed for all characteristics included in
the standard for which the manufacturer declares the performance:
— at the beginning of the production of a new or modified active road stud (unless a member of the
same product range); or
12

---------------------- Page: 14 ----------------------
oSIST prEN 1463-3:2017
prEN 1463-3:2017 (E)
— at the beginning of a new or modified method of production (where this may affect the stated
properties); or
they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the active road
stud design, in the raw material or in the supplier of the components, or in the method of production
(subject to the definition of a family), which would affect significantly one or more of the characteristics.
Where components are used whose characteristics have already been determined, by the component
manufacturer, on the basis of assessment methods of other product standards, these characteristics
need not be re-assessed. The specifications of these components shall be documented.
Products bearing regulatory marking in accordance with appropriate harmonized European
specifications may be presumed to have the performances declared in the DoP, although this does not
replace the responsibility on the active road stud manufacturer to ensure that the active road stud as a
whole is correctly manufactured and its component products have the declared performance values.
6.2.2 Test samples, testing and compliance criteria
The number of samples of active road studs to be tested/assessed shall be in accordance with Table 2.
