of correct procedure

4 Wear simulator facility
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.

1 wheel stations 6 wheel suspension
2 test tyre (8) 7 bearing
3 road marking samples 8 electric/hydraulic engine
4 turnable diameter 6,40 9 samples, test surface
5 turntable bearing assembly

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
