be supplied in single or multi-component systems. The solids comprise are inorganic and/or organic fillers,
pigments and additives

prEN 12802:2008 (E)
3.1.1.2
single-Component-High Solid paints (SCHS)
the cohesive film of a single-component High Solid is formed only by evaporation of the solvent and physical
curing.
3.1.1.3
multi-Component-High Solid paints (MCHS)
multi-component-High Solid paints consist of two or more components. The cohesive film is formed after mixing all
components by the evaporation of the solvent and a chemical reaction. The Application is possible within the pot-
life-time.
3.1.2
waterborne Paints
a liquid product containing suspended solids in an aqueous liquid. It can be supplied in single or multicomponent
systems. When applied it produces a cohesive film by the process of aqueous liquid evaporation and /or chemical
process
3.1.2.1
dispersions
dispersions are liquid or viscous products containing solids and liquid additives dispersed in an aqueous liquid. The
aqueous liquid consists of the binder polymers and mainly of water. The solids comprise inorganic and/or organic
fillers, pigments and additives. The content of volatile organic solvents is limited to 2 % weight by weight, the total
amount of volatile organic compounds (VOC) is limited to 3 % weight by weight.
3.1.2.2
dispersion paints
the volatile component is mainly water. The content of organic solvents is limited to 2 % weight by weight, the total
amount of volatile organic compounds (VOC) is limited to 3 % weight by weight.
The solid content is lower than 80 % weight by weight. The cohesive film of a dispersion paint is produced by the
process of water evaporation.
3.1.2.3
high solid dispersions
the volatile component of a high solid dispersion is mainly water with a content lower than 20 % weight by weight,
the content of solids is equal to or higher than 80 % weight by weight. The content of organic solvents is limited to 2
% weight by weight, the total amount of volatile organic compounds (VOC) is limited to 3 % weight by weight. The
cohesive film of a High-Solid dispersion is produced by the process of water evaporation and a chemical cross-
linking reaction.
3.2
cold plastics
cold plastics are viscous products supplied in two or multi-component forms (at least one main component and a
hardener system). They are free from solvents. The cohesive film is formed after mixing of all components only by
a chemical reaction. Following the reaction the liquid becomes a solid.
3.2.1
cold-setting reactive materials (cold plastics)
cold plastics consist of a minimum of two components. One component contains a hardener and another
component the accelerator. Depending on the system the components are mixed in various ratios. The application
is only possible within the pot-life-time.
3.2.2 energy Induced Curing Materials (EICM)
energy induced curing materials produce a cohesive film under the influence of energy
(e.c. heat, UV-radiation).

3.3
thermoplastics
a solvent-free marking substance supplied in block, granular or powder forms. It is heated to a molten state and
then applied. It forms a cohesive film by cooling.
NOTE Additional materials to those described in 3.1 to 3.3 can include, if recommended by the manufacturer,
primers which are liquid products which may contain solids and liquid additives suspended in an organic solvent or
in water. The solids comprise inorganic and/or organic fillers, pigments and additives. The content of volatile
organic solvents is not limited.
Primers are used to precoat road surfaces before the road marking system is applied. They improve the adhesion
of the road marking and protect against disintegration, discolouring etc. caused by incompatible compounds in the
road surface.
4 Sampling
Samples representative of each component of the material shall be taken from storage in accordance with ENV
13459-1. Smaller representative samples, of sufficient quantity to carry out all the tests required, shall be taken
from the larger samples. For paints and cold plastics approximately 1 l of the basic component shall be taken.
In the case of thermoplastic in powder form sufficient quantity shall be taken in accordance with ENV 13459-1 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 1 kg of homogeneous solid material shall be taken for
