4.1 Turntable
The mobile part of the wear simulator consists of a turntable with an external diameter of 6,4 m comprising a
number of running wheels with loaded axles, a number of test plates mounted in a plane and driving mechanism
capable of a relative movement, in which the wheel(s) overrun the test plates repeatedly. The rotation can be done
in both directions (see figure 1) at a tangential speed between 5 and 90 km/h.

prEN 13197:2008 (E)


4.2 Test plates housing
The turntable's rim is provided with a number of housings to fix the test plates. These housings must
comply with the following requirements.
4.2.1 Dimensions
They have to be sufficient to allow the use of the appropriate measurement equipment. The minimum
required dimension on the parallel direction to the movement of the loading wheels is 190 mm, although
the use of some commercial measuring equipment requires longer distances.
4.2.2 Location
All of them shall be fixed at a position in the rim to provide a rolling-line defined by a diameter of 585 cm ±
5 cm measured by the central point in the cap of tyre. The layout must guarantee that the location of the
test plates has no influence in the results.
4.2.3 Fixation system
The fixation of the test plates allows
- the top of the test plates to be at the same level that the housing external part to avoid create jumping,
- a uniform rolling surface without skidding or vibration and
- an absolute immobility of the test plates on their housings.
4.3 Cleaning system
The wear simulator shall have appropriate equipment in order to eliminate effectively and in a few wheel
passages the particles that, potentially, could leave the film and to keep the tyres clean and cool; they may
be:
- Brushes
- Jet air
- Vacuum cleaner
- Water and air atomizers
- others
NOTE 1: During the wearing process, some components of the road marking materials (mainly particles of drop-on
materials) may leave the film and, if not removed, may adhere the tyres and cause an additional and uncontrolled
wear. This effect may be especially serious when the materials under test are thermoplastics and the tyres, if not
sufficient cool and clean, may become tacky as consequence of the adherence of thermoplastic binder.
NOTE 2: The test method may also specify additional cleaning possibilities such as to include an initial short cycle
with the aim of removing in a first stage the particles badly adhered to the applied road marking and the possibility
of allowing the tyres to wheel passages the road marking and the pavement (test plates without road marking
material) alternatively
4.4 Water dispenser
The wear simulator shall have a water dispenser able to add water over the test plates.
4.5 Test room
The wear simulator is located into a test room isolated and air-conditioned.
4.6 Wheels
Stress load is created by the effect of a number of wheels rolling over the test plates. The stress load
depends on the number of wheels, on the type of tyres, on the load itself, on the inflate pressure, on the
support and steering angles and on the alignment.
4.6.1 Number of wheels
The stress load may be created by the effect of two or four pairs of wheels situated in opposite positions.
For CE marking purposes two pairs shall be used.
4.6.2 Type of tyres
For the selection of the tyres the following recommendations shall be followed:
- dimensions: The tyres will have a commercial size of 205/65, able to give an homogeneous rolled width of,

prEN 13197:2008 (E)
at least, 150mm.
- pattern: symmetric (whenever possible)
- nature: specific commercial tyres
NOTE: Manufacturers are continuously modifying both the nature and the pattern of the commercial tyres for what
it is not advisable to establish any specification.
The approval of the specific commercial tyres shall be done by submitting the control plate (see 7.2) to a
real run test, using the wheels to be tested, up to a minimum traffic class of P6 (see 8.4.3 table 4). The
tyres shall be approved if the result on the control plate does not deviate from the known and controlled
characteristics in excess of the percentages listed in 8.2.
New tyres shall be used for each test
4.6.3 Wheel load
The wheel load on the turntable may range between 0 N and 4 000 N.
4.6.4 Inflate pressure
It may range between 0 and 0,3 Mpa.
4.6.5 Steering and support angles
The fixation system of the wheels has to allow the adjustment of the steering angle with a tolerance of
±10’and the support angle with a tolerance of max. -20’
NOTE: The steering angle can considerably influence the amount of abrasion of the marking material. The support
angle influences in case of differenced diameters and velocities between inside and outside the tyres the nature of
abrasion pattern.
4.6.6 Alignment
The fixation system of the wheels has to allow small adjustments in the alignment in order to compensate
the effects of different tyre’s patterns.
NOTE: Some patterns of the commercial tyres may cause –when the wheels are aligned- the presence of some
narrow lines with lower abrasion. This effect may be compensated with slight changes on the alignment.
4.7 Measurements in relation to equipment
The following parameters shall be measured, controlled and recorded:
- Date and time
- Turntable speed
- Turning direction
- Room temperature
- Test plate surface temperature
- Load per wheel
- Number of wheel passages (wp)
- Steering angle
- Support angle
- Inflate pressure
The Laboratory shall have available the necessary equipment and procedures to ensure the traceability of
the measurements

5 Test plates
The road marking materials to be tested in the wear simulator have to be applied on test plates. The
results are highly dependent on the substrate: roughness but also on the nature and size (for a reliable
result a minimum surface of road marking material has to be tested).
5.1 Substrate nature
The body of test plates shall be manufactured with materials of sufficient rigidity to do not modify the
surface texture during the test process and to be able to be handled without obvious bending or breaking
up at temperatures up to 50 °C .

When other than a bituminous material is used for manufacturing the test plates the surface shall be
coated with approximately 50 g/m² of bitumen Type B 70/100 or similar. The bitumen may be applied in
one or more coating of diluted bitumen in such a way that enough adherence of the bitumen to the
substrate is achieved.

prEN 13197:2008 (E)

5.2 Roughness
The roughness of the test plate surfaces, measured as texture depth in accordance with the method
described in EN 13036-1, shall comply with some of the classes listed in Table 1.
For CE marking purposes only classes RG1 and RG2 shall be used.

Table 1- Classes of roughness
Class of roughness texture depth in mm according EN 13036-1
RG1 0,40 ± 0,10
RG2 0,70 ± 0,10

RG3 1,00 ± 0,10

RG4 ≥ 1,20

A sample of test plates shall be submitted periodically to the test process in order to determine if after the
test process they are still in the same class of roughness.

NOTE Sometimes, to stabilise the texture of the test plates it is convenient to submit them to a
preparatory wheel passages process.

5.3 Size (useful surface)
The size of the test plates shall to be sufficient both for the wheels to pass entirely over the plate and for
the necessary measurements to be performed allowing the use of the appropriate measurement
equipment.
For testing a road marking material, there shall be used the necessary number of test plates to complete a
measurement area of, at least, 800 cm².
NOTE: The longer are the test plates (in one piece) the more reliable are the photometric measurements
particularly for night-time visibility under wet and rain conditions. Test plates of 45 cm have shown good
performance in these cases.

6 Sampling
For identification of tested road marking materials and for laboratory tests the necessary samples shall be
taken according to EN 13459 from each road marking material, from all of its components in case of a
multiple component material, and from drop-on materials.

NOTE 1 For materials used in more than one application, it is sufficient to take samples in connection with one
application only.

NOTE 2 The participants can agree to include further specifications for sampling, such as quantities to sample.

7 Preparation of samples (application on the test plates)
The test results depend on various factors related to the application of the road marking materials, mainly
on the application instructions (type of application and quantities applied) on the direction of application (in
relation to the wearing process and the direction of measurements) and on the drying or hardening
conditions (conditioning).
A particular case is the preparation of a sample as a reference or control plate.

7.1 Application instructions
The applicant shall specify the application instructions for the road marking system including all needed
components and quantities of those, also the type of application.

oSIST prEN 13197:2009
prEN 13197:2008 (E)
7.1.1 Type of application
In principal, road marking materials should be applied using the type of application (e.g. spray or extrusion)
used in practice.
Other methods of application, appropriate for laboratory conditions, may be used whenever they ensure
the required layer thickness or weight and distribution (transversal and longitudinal) and be approved by
the manufacturer (applicant).
The method and data of application shall be recorded in an application report.

7.1.2 Quantities applied (rate of application)
The application shall be carried out in such a way that
- The layer thickness and/or the layer weight and
- the quantity of drop on materials remaining on the road marking to be tested.
when measured in accordance with the specifications given in clause 7.5.3 does not differ by more than 10
% from the required quantities specified by the manufacturer.
NOTE: The remaining material on the road marking is relevant for performance information. The consumption may
be relevant for cost information and the participating parties may agree its evaluation for this purpose.
7.2 Control plate (reference)
At least one test plate of a standard material and with a standard road marking material shall be included
in each test run for indication of correct procedure (control plate).
The control plate is defined for each laboratory including the specifications of the material(s), the
application instructions and the results to be achieved under the standard test conditions. If relevant for the
intended use, the laboratory may define more than one control plate.
The results of the control plate in each particular test shall be used as an acceptance or rejection criteria
for the particular test. The successive results shall be used for determining the repeatability of the test
method.
7.3 Test plate orientation (direction of application)
The application on the test plates have to be carried out taking into account that the test plates have to be
aligned in the wear simulator so that the road markings are parallel to the movement of the loading wheels
relative to the test plates.
7.4 Conditioning
The prepared test plates shall be dried (or to harder) in a conditioned chamber at a temperature of 20°
(±5°C) and a relative humidity comprising between 45% and 75%.
Test operation for paints will commence eight days, at the earliest, and twelve days, at the latest, following
the application of test samples. The conditioning periode for water-based paints shall be one week more
than solvent paints. For other products the minimum conditioning period is 48 hours.
Other conditions, if required for the applicant, shall be possible and reported.
7.5 Measurements in relation to application
7.5.1 Test conditions during application
Road marking materials shall be applied when the air temperature is between +10 °C and + 35 °C and
relative humidity is below a maximum of 80 %. The prevailing climatic conditions during application shall
be measured and reported.
7.5.2 No pickup-time
When required by the participating parties, the no pickup time shall be measured in conjunction with the
application of a road marking material as sp
