4 Test sites and conditions
4.1 General
Test sites shall be arranged at suitable locations in accordance with 4.2 to 4.5. The test results may
depend on test field location, climate, road surface and traffic which shall be described according to 4.2
to 4.6.
4.2 Test sites characteristics and location
The test site shall be located in an area which belongs to one of the climatic classes defined in 4.3.
The test site shall consist of a field, where the road marking materials are to be applied. The roads used
for test sites should be straight and flat and without junctions, substantial obstacles to daylight, sources
of frequent dirt (quarries, field exits, etc.) or tracked vehicles.
NOTE It is desirable to have additional areas at the roadsides and/or at both ends in order to allow safe
working conditions and convenient operation of application with road marking equipment.
The percentage of heavy vehicles on the test site shall be 5 % to 25 % of all vehicles.
The location of the test site shall be indicated in the test report.
4.3 Climatic conditions and classes
Climatic classes (see Table 1) are defined according to the Köppen classification and the use of winter
maintenance.
Köppen classification shall be determined according to Annex A.
Winter maintenance is defined by the number of times that snowplough have operated on the test field
during the road trials. Winter maintenance is applicable if this number is equal to or greater than 20
and shall be considered only for the Köppen zone Cfb.

prEN 1824:2018 (E)
NOTE 1 Road trials on cement concrete surfaces do not give repeatable results because of on-going chemical
reactions.
At the commencement of a road trial, a road surface report of the road trial shall be available. The test
surface report shall include a general description of the road surface and an account of the texture
depth (MTD: mean texture depth), determined in accordance with EN 13036-1.
The MTD shall be measured at several locations on the test field. The number of measurements depends
on the test field length. Measurements shall be carried out, at least, at three transversal locations and
repeated every 30 m on the test field. The transversal measurements locations are in the centre of the
carriageway, near the right and left edge line.
The average mean texture depth is derived from these measurements. The standard deviation shall be
less than 0,15 mm.
The averaged texture depth may also be directly determined in accordance with EN ISO 13473-1.
Depending to the averaged measured texture depth, the test field roughness is described in term of
roughness class according to Table 2.
Table 2 — Test field roughness classes
Roughness class Averaged measured texture depth
RG1 ≤ 0,60 mm
RG2 > 0,60 mm and ≤ 0,90 mm
RG3 > 0,90 mm and ≤ 1,20 mm
RG4 > 1,20 mm
NOTE 2 The texture depth has an influence on the result of road trials, at least for materials applied in thin
layers.
4.5 Roll-over classes
The volume of traffic shall be such as to ensure that one or more measurement areas with the desired
roll-over class can be selected (see 7.3).
At the termination of a road trial, a traffic report for the duration of the road trial should be made
available. The traffic report shall include the roll-over classes according to Table 3, determined on the
measurement area(s) in accordance with Annex B.

P5 1 000 000 ± 20 %
P5.5 1 500 000 ± 10 %
P6 2 000 000 ± 10 %
NOTE The roll-over classes T0, T1 and T2 are for materials intended for
temporary road markings, while the roll-over classes P0 to P6 are for materials
intended for permanent road markings.
The traffic report should further include the percentage of heavy vehicles together with an indication of
the counting method used.
A vehicle is considered a heavy vehicle if its maximum gross mass is above 7 500 kg.
4.6 Studded tyres
For road trial sites where studded tyres are used, this shall be indicated on the test report. When
available, the percentage of vehicles with studded tyres shall be indicated in the report.
NOTE From general experience, such traffic conditions can be relevant to the erosion of road markings.
5 Organization of road trials
5.1 Duration
A road trial shall include at least one full climatic cycle of one year for materials intended for permanent
road marking and up to 6 months for materials intended for temporary road marking. In order to be
able to organize road trials on a yearly basis on the same road site, the minimum duration may be
reduced to 10 months (provided that the winter period is included in these 10 months). The test
reports shall always precise the duration of the road trials.
5.2 Transverse and longitudinal application patterns
5.2.1 General
Road marking materials shall be applied in patterns of lines either transverse or longitudinal to the
road.
When a long (more than 40 cm) measurement area is necessary, the transverse pattern cannot be used.
When both the transverse and longitudinal patterns are used on the same test site, they shall be used on
separate parts of that test site.

5.2.2 Transverse pattern
At least three lines shall be applied for each road marking material. The distance between two adjacent
lines should be at least 0,35 m and the width at least 0,15 m as shown in Figure 1. The application could
be done across one or two lanes.
NOTE Lines of the same material need not be adjacent.

5.2.3 Longitudinal pattern
Lines are applied in transverse rows and longitudinal columns. For each of the road marking materials
there shall be one line in each column containing measurement areas (see 7.3.2.3).
The lines should be at least 0,13 m wide and at least 1 m long as shown in Figure 2. Unmarked space
between the lines is a minimum of 0,5 m in the longitudinal direction.

6.2 Periods for application
Road marking materials shall be applied when the weather conditions are as defined in 6.3.
NOTE The participating parties can agree to include one or more periods for application. One period can, for
instance, be for materials intended for use as temporary road markings and another for materials intended for use
as permanent road markings. There are practical advantages to having the period(s) as short as possible.
For temporary road marking materials, the application period shall be such that the required roll-over
classes are reached, and the subsequent measurements carried out, prior to or after winter conditions.
6.3 Conditions suitable for application
Conditions shall be deemed suitable when:
a) the road surface appears to be dry and dew is not being formed;
b) the road surface temperature is within limits agreed upon by the participating parties;
c) the wind speed is less than the maximum agreed upon by the participating parties.
Special road marking materials can be applied in other weather conditions, which shall be noted in the
individual test report (see Clause 8).
EXAMPLE The road surface temperature is at least 3 °C above the dew point of the air, the road surface
−1
temperature is between 10 °C and 50 °C and the maximum wind speed is less than 10 m × s .
6.4 Technical specification for application
Prior to the commencement of the road trials, the applicant shall submit to the test authority the
application instructions of the road marking material.
Motorized equipment shall be used to apply the base material, with the exception of the preformed road
markings that are to be applied manually. Other methods of application may be proposed with technical
justification from the applicant and approval of the organization.
The drop-on material shall be applied mechanically. If the test authority and the applicant agree to test
road marking equipment prior to the application of a road marking material, the rate of application of
marking materials and of drop-on materials shall be adjusted and the rate of application applied
verified in accordance with Annex C. A road marking equipment shall be rejected if any of three rates of
application applied in three successive test runs deviates more than 20 % from the average rate of
application.
NOTE 1 The application instructions will include preparation methods (such as how to melt a thermoplastic
material), what type of application to use (e.g. extrusion of a thermoplastic material), any particular road marking
equipment required, the pattern of application (e.g. plain or a certain type of structure), the rate(s) of application
(in grams per square metre), what drop-on materials to add, their rate(s) of a
