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 clauses 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, with extra space at both
ends. 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 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 10% 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 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.

4.4 Road surface conditions and classes

Road trials shall be carried out on asphaltic road surfaces of an age of 1 year or more, which are in good condition
and not in need of repair for the duration of the road trials and are not damaged by the presence of wheel tracks,
fissures, cracks or similar. Highly porous surfaces shall be avoided.

NOTE 1 Road trials on cement concrete surfaces do not give repeatable results because of on-going chemical reactions.

NOTE 2 Road trials on highly porous surfaces do not give comparable results due to the draining properties.

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 :”Measurements of pavement surface macrotexture
depth using volumetric patch technique”

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 30m
on the test field. The transversal measurements locations are in the centre of the carriageway, near the right and
left edge line.

The averaged mean texture depth is derived from these measurements. The standard deviation shall be less than
0,15 mm.

NOTE 3 The averaged texture depth may also be directly determined in accordance with EN ISO 13473-1 “Characterization
of pavement texture by use of surface profiles – Part 1 – Determination of Mean Profile Depth”. 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 4 The texture depth has an influence on the result of road trials, at least for materials applied in thin layers.

4.5 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 7.2).

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.

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 7500 kg.

4.6 Studded tyres classes

For road trial sites where studded tyres are used to a significant degree, this shall be indicated on the test 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 some cases test markings may fall below the performance requirements of the road authority. In these
cases, it may be necessary for the markings to be removed.

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 30 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.

6.1 Periods for application

Road marking materials shall be applied when the weather conditions are as defined in 6.2.

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 number of wheel
passages is obtained, and the subsequent measurements carried out, prior to or after winter conditions.

6.2 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 .

6.3 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.

NOTE 1 The application instructions shall 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 application and the method to use.

Whenever possible the road marking material shall be applied using self-propelled road marking equipment, and
drop-on materials shall be applied mechanically.

NOTE 2 Most materials, except preformed materials, can be applied using self-propelled road marking equipment; this
ensures better repeatability of the application.

NOTE 3 The road marking equipment used can either be those put to general commercial use or special road marking
equipment. The road marking equipment can be operated by the usual crews or by staff at the test site.

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.

6.4 Sampling and measurements

6.4.1 Sampling

When samples are required for identification or other purposes, each road marking material, all the components of
a multiple component material, and drop-on materials shall be taken into account.

NOTE 1 The sampling may be realized according to EN13459.

---------------------- Page: 12 ----------------------
oSIST prEN 1824:2009
prEN 1824:2008 (E)
NOTE 2 For materials used in more than one application, it is not necessary to sample every application.

NOTE 3 The participating parties can agree to include further specifications for sampling, such as quantities to sample.

NOTE 4 If diluents are allowed and used for the application, the rate of dilution shall be verified sampling materials both from
the original container and from the tank.

6.4.2 Measurement of drying time and weather conditions

When required by the participating parties, the drying time shall be measured for paints and cold plastics.

The drying time shall be determined in accordance with annex D for every line that contains a measurement area
(see 7.2) for further measurements.

The drying time shall be reported together with an account of the weather conditions, including the ambient
temperature, the road surface temperature, the relative air humidity and the wind speed as measured during
application in accordance with annex E.

6.4.3 Determination of the useful and consummated rates of application

During the application of a road marking material, the useful rates of application of the material and of any drop-on
or non drop-on material shall be determined in accordance with annex C. When the consummated rates application
are also required, they should be also determined in accordance with annex C.

NOTE The participating parties can agree to include a criterion for the acceptability of the application of a road marking
material. For example, the application is rejected if any of the rates of application from the different lines deviates more than 10
% from the average rate of application, or if the average rate of application deviates more than, for example, 15 % from the rate
of application given in the specification for the material.

7 Measurements related to performance

Test lines shall only be washed when it is necessary to do so and by agreements between the
participating parties. Washing shall be with a soft brush using clear water. The performance shall be then
determined once the product is dry.

Annex A
(normative)

Köppen classification

The aim of this annex is to determine in which climatic area belongs a test field using the Köppen classification
system.

A.1 Generalities
The Köppen Climate Classification System is the most widely used for classifying the world's climates. It defines six
major climate types based on annual and monthly averages of temperature and precipitation. Each type is
designated by a capital letter (A, B, C, D, E and H).

Further sub-types, designated by a second lower case letter (f, m, s or w), were established to distinguish specific
seasonal characteristics of temperature and precipitation.

To further denote variations in climate a third lower letter (a, b, c, d, h or k) was added.

Clauses A.2 to A.5 present the different steps that shall be used to determine the Köppen climate type from
meteorological data measured closed to the test field. Temperature and rainfall parameters have to be derived from
the last 30 years.
A.2 Step 1 : Determine whether a climate is arid/semiarid (climate B)
A.2.1 Determine the annual rainfall r (in mm) and the annual average temperature t (in °C).

A.2.2 If r > 20 (t+14) it is not a climate B. Go to A.3.

A.2.3 Determine the rainfall distribution. Then determine Bs, Bw or neither according to the criteria given in table
A.1 below.

r > 20 x (t+7) 10 x (t+7) (neither of above)
A.3 Step 2 : If not a B Climate, identify the climate as A, C, D or E according to
temperature data
The climate is determine according to temperature of coldest (t ) and/or warmest month (t ).
