4 Sampling

Samples may be taken from storage, from material provided on work site, or from the application

equipment on site.

Samples representative of each component of the material shall be taken from storage in accordance

with EN 13459.

Sampling prior to application can be carried out from the application unit of the road marking machine

and/or the provided container. If the material is suspect to be non-homogeneous take some samples

from different areas of the container or during the application of the road marking out of the application

unit. For paints and cold plastics at minimum 2 × 1 l of the basic component shall be taken.

In the case of thermoplastic in powder form, sufficient quantity shall be taken so that it can be melted in

a metal container and mixed to a homogeneous mass. After cooling and casting into solid sheets or

blocks, representative samples of approximately 2 × 1 kg of homogeneous solid material shall be taken

for testing.

5.3 Preformed road markings
The identification methods for preformed road markings are laid down in EN 1790.
5.4 Premix particles and/or glass beads
5.4.1 Granulometry

The granulometry shall be determined using digital image analysis or the method laid down in EN 1424

or EN 1423.
5.5 Tolerances
Tolerances are as shown in Table 1.
Manufacturers tolerances shouldn't be greater than in Table 1 declared.

If the manufacturer can't provide values or parameters requested by the authorities necessary for the

certification process the authorities authorized lab determines that values or parameters.

For the initial testing of a material, tolerances apply to the manufacturers declared mean values for the

properties tested and the initial test results shall be within the tolerances, related to the mean value, in

Table 1.

When the values fall inside the tolerances then the values initially declared by the manufacturer are

considered to be verified.
When values fall outside of the tolerances there are four possibilities:
— the manufacturer can decide that the test be terminated;

— by agreement between the participants the test can be repeated with the same samples;

— by agreement between the participants the test can be repeated with new samples;

— by agreement between the participants the manufacturer can submit revised declared values;

peaks are present or there are additional occurrences which are significantly different from the baseline

to stand out. The relative height levels between the peaks shall not change significantly.

At the end of the tests, the test report shall be made available. The test report shall include at least: a

reference to this standard and to the test method (Annex A to Annex H); the critical testing conditions;

Annex A
(normative)
Paint – Test method for the determination of the solids/solvent content
A.1 Principle

The volatile constituents of the paint are evaporated at 105 °C. The residual solids are weighed and the

solids content calculated.
A.2 Apparatus
a) Porcelain basins with a minimum diameter of 40 mm.
b) Analytical balance, with an accuracy of 0,001 g, with zero point correction.
A lower accuracy balance may be used provided large sample size is used.

c) Warming cupboard, with forced fresh air ventilation and flame-proof interior capable of being

heated to 105 °C ± 2 °C.
d) Desiccator, with drying agent, e.g. silica gel.
A.3 Reagents

Thinner consisting of a suitable solvent/thinner as recommended by the manufacturer.

A.4 Procedure
A.4.1 Carry out two determinations.

A.4.2 Mark porcelain plates with numbers. Record the mass of the empty plates (L) to the nearest

0,01 g. Place approximately 2 g of the paint, and homogenized, in the plate with a spoon. Weigh to the

nearest 0,01 g (mass M ).

A.4.3 Place the plates containing the sample in a warming cupboard at a temperature of 105 °C ± 2 °C

and store there for at least 3 h or until constant mass is reached. Constant mass is reached when, the

mass loss is less than Δ = 0,2 % change in mass. Cool the plate to room temperature in the desiccator,

and weigh to the nearest 0,01 g.
A.5 Test result

The percentage solids content of the paint by mass, S, shall be calculated according to the following

formula:
100 ML−
( )
2 S
S= (A.1)
ML−
1 S
and the difference to the initial mass give the solvent content SC:
SC 100− S (A.2)
---------------------- Page: 11 ----------------------
oSIST prEN 12802:2019

where
M is the initial mass of paint together with the empty plate, in grams;
M is the final mass of solid together with the plate, in grams;
L is the mass of the empty plate, in grams.

If the results of the individual determinations differ by more than 0,5 % by mass the procedure shall be

repeated. The mean of the two individual results shall be calculated and the solids content given

rounded to the nearest 0,1 % by mass.

Annex B
(normative)
Paint, thermoplastics and cold plastics – Test method for the determination
and identification of organic constituents
B.1 Principle

The determination of the part of organic constituents is carried out by combustion. The binder type of

paints and thermoplastics and cold plastics is identified by IR spectra using a potassium bromide (KBr)

pellet or window.

Volatile components of paints and cold plastics (solvents and monomers) are identified using the

method described in Annex F.

The inorganic constituents are kept for further IR examination (Annex C), determination of titanium

dioxide (Annex D) and the glass bead/premix content (Annex E).

b) centrifuge bowls, steel bowls or glass tubes, each with a capacity of about 80 cm

c) spatula;
