Overview

prEN 1790 is a CEN draft standard for preformed road markings (marking tapes and preformed markings) intended primarily for permanent use on roads. It defines required product characteristics, laboratory test methods, reporting formats and the procedures for assessment and verification of the constancy of performance (AVCP). The document covers types I and II (structured and non‑structured) preformed products and aligns with related CEN work such as EN 1436:2018. Hot‑applied thermoplastics that require addition of drop‑on materials are excluded (see EN 1871:2020).

Key topics and technical requirements

• Essential characteristics: daytime visibility (reflection), night‑time visibility (retroreflection under vehicle headlamps), chromaticity coordinates for day and night colours, and skid resistance (SRT for non‑structured products).
• Durability testing: laboratory wear simulators (turntable) and road trial procedures to assess service life and performance retention.
• Resistance to UV exposure: accelerated ageing test methods for colour and retroreflectivity stability.
• Identification and composition tests: ash content, thermogravimetric analysis (TGA), FT‑IR and ATR spectroscopy for material fingerprinting and adhesive layer analysis.
• Sampling, test reporting and expression of results: standardized preparation of test samples and formats for test reports to support conformity claims.
• Assessment & verification of constancy of performance (AVCP): Factory Production Control (FPC) requirements, initial inspection, ongoing surveillance and procedures for modification and one‑off or prototype products.
• Annexes: normative methods for temporary preformed markings (removability), material identification, and detailed test procedures (TGA, FT‑IR, ash content, adhesive mass per unit area).

Applications and users

Who uses prEN 1790:

• Manufacturers of preformed tapes and sheets for product development, quality control and CE marking preparation.
• Independent testing laboratories conducting retroreflectivity, chromaticity, skid resistance and durability tests.
• Road authorities and specifiers writing procurement documents and performance specifications for permanent road markings.
• Contractors and installers needing to verify product conformity and installation quality.
• Conformity assessment bodies implementing AVCP and Factory Production Control (FPC) systems under the Construction Products Regulation (Regulation (EU) No. 305/2011).

Practical uses:

• Creating technical datasheets and performance declarations.
• Comparing products for retroreflectivity, durability and skid resistance.
• Supporting procurement decisions and lifetime cost assessments for road safety measures.

Introduction
A particular category of road marking materials, used for horizontal signalisation, are
preformed road markings, manufactured products in the form of sheets or on rolls, ready for
use on the road. They can be applied by means of adhesives, pressure or heat, with or without
the use of a primer. Preformed road marking materials can be linear, in pieces of a certain
length or in rolls. They can also be cut out in the form of symbols or signs or parts of them,
making it possible to assemble them on the road to achieve the desired shape.
Preformed road marking materials can be designed for use as permanent or temporary road
markings. Temporary road markings, as covered in Annex A, are applied with a view for later
removal and therefore the specific property of “removability” can be required.
Preformed road marking products are defined as Tape, preformed Cold Plastic road marking
or preformed Thermoplastic road marking.
These type of products are fully finished during manufacturing and do not change significantly
their properties during application. They are completely covered by this standard.
Release of dangerous substances
National regulations on dangerous substances may require verification and declaration on
release, and sometimes content, when construction products covered by this standard are
placed on those markets.
In the absence of European harmonized test methods, verification and declaration on
release/content should be done taking into account national provisions in the place of use.
NOTE An informative database covering European and national provisions on dangerous substances is
available at the Construction website on EUROPA accessed through: http://ec.europa.eu/growth/tools-
databases/cp-ds_en.
1 Scope
This document specifies construction products which are white and yellow, removable or non-
removable, preformed road marking materials, under the form of tape, cold plastic,
thermoplastics (without addition of drop-on materials during application), to be used for
permanent and/or temporary road markings in circulation areas. Other preformed road
marking products and colours intended for road markings are not covered in this document.
This document also gives specifications for the evaluation of conformity for white and yellow,
removable or non-removable, preformed road materials under the form of tape, cold plastic,
thermoplastics to be used for permanent and/or temporary road markings in circulation areas
including type testing and factory production control.
This document includes an Annex ZA for permanent tapes, preformed cold plastic road
marking and thermoplastic road marking with the clauses addressing the provisions of the EU
Construction Product Regulation for permanent road marking.

4 Product Characteristics
4.1 General
The performance is meant as characteristic of the material as fully finished product. The
performance can be assessed on samples in a laboratory, but also on samples applied on the
road or wear simulator. The performance shall be measured after removing any surface
coating used to protect the surface of the preformed road marking during roll-up and
transport, following the instructions of the manufacturer.
4.2 Essential Characteristics
4.2.1 Day-time Visibility (Reflection in daylight or under road lighting)
Reflection in daylight or under road lighting is measured either by the luminance coefficient
−2 −1
under diffuse illumination Qd in the direction of traffic and expressed in mcd⋅m ⋅lx ; or by
the luminance factor β.
a. When luminance coefficient under diffuse illumination Qd is measured, the preformed
road marking material is tested in accordance with 5.2.2 a), test results shall be expressed
by means of classes Q0 to Q5 of EN 1436:2018, Table 1.
b. When luminance factor β is measured, the preformed road marking material is tested in
accordance with 5.2.2 b), test results shall be expressed by means of classes B0 to B5 of
EN 1436:2018, Table 2.
4.2.2 Night-time Visibility (Retroreflection under vehicle headlamp illumination)
Retroreflection under vehicle headlamp illumination represents the brightness of a road
marking as seen by the vehicle driver under the illumination by the vehicle’s own headlamp.
−2 −1
The result is expressed by the coefficient of retroreflected luminance R in mcd·m ·lx .
L
The coefficient of retroreflected luminance, measured on dry conditions, changes during
wetness or during rain. Retroreflected luminance during wetness or during rain only applies
for type II road markings.
a. When preformed road marking material is tested on dry conditions, in accordance with
5.2.3 a), test results shall be expressed by means of classes R0 to R5 of EN 1436:2018,
Table 3.
b. When preformed road marking material is tested during wetness in accordance with 5.2.3
b), test results shall be expressed by means of classes RW0 to RW6 of EN 1436:2018,
Table 4 (only for type II road marking products).
c. When preformed road marking material is tested during rain in accordance with 5.2.3 c),
test results shall be expressed by means of classes RR0 to RR6 of EN 1436:2018, Table 5
(only for type II road marking products).
4.2.3 Day-time Visibility (Chromaticity coordinates)
Chromaticity in daylight shall be defined by means of (x,y) chromaticity coordinates.
When a white preformed road marking is tested in accordance with 5.2.4, test results shall be
expressed by means of colour regions defined by the corner points given in EN 1436:2018,
Table 6 for white road markings.
When a yellow preformed road marking is tested in accordance with 5.2.4, test results shall be
expressed by means of colour regions defined by the corner points given in EN 1436:2018,
Table 6 for yellow road markings.
4.2.4 Night-time Visibility (Chromaticity coordinates)
Chromaticity in nighttime for retroreflected light shall be defined by means of (x,y)
chromaticity coordinates.
When a dry yellow preformed road marking is tested in accordance with 5.2.5, test results
shall be expressed by means of colour regions defined by the corner points given in
EN 1436:2018, Table 7 for yellow road markings.
4.2.5 Skid resistance SRT value (only for non-structured road marking products)
Skid resistance represents the energy loss caused by the friction of a rubber slider over a
specified length of a road marking surface in wet conditions. The result is expressed in SRT
(Skid Resistance Tester) units.
Measured according to 5.2.6, test results shall be expressed by means of classes S0 to S5 of
EN 1436:2018, Table 8.
This test is valid for flat road markings and road markings with low degree of texture. Road
markings with high degree of texture or structured markings may not be suitable for
measurement of skid resistance by this method, see definitions in EN 1436:2018, 4.5.
4.3 Durability
4.3.1 General
Durability represents the capability of the preformed road marking material to retain the
performance of the essential characteristics declared by the manufacturer after being
submitted to road trials and/or wear simulator.
This European Standard considers two possible methods of verification and/or assessment of
durability taking into account that some Member States have national regulations based on
one of them and considering that state of the art on this matter does not allow to define a single
and unified test method.
The information corresponding to the durability method road trials or wear simulator shall
include the specific test conditions applicable to the test.
The following performance characteristics of the road marking assemblies are tested by road
trial or wear simulator:
— Retroreflection under vehicle headlamp illumination (see 4.2.2):
— coefficient of retroreflected luminance R expressed as class R on dry conditions (only
L
for retroreflective road marking products);
— coefficient of retroreflected luminance R expressed as class RW during wetness (only
L
for Type II road marking products) and/or;
— coefficient of retroreflected luminance R expressed as class RR during rain (only for
L
Type II road marking products);
— Reflection in daylight or under road lighting (see 4.2.1):
— luminance coefficient under diffuse illumination (Qd) or luminance factor (β)
— Colour – Chromaticity (see 4.2.3 and 4.2.4):
— chromaticity coordinates (x, y);
— Skid Resistance SRT value (only for non-structured road markings) (see 4.2.5).
4.3.2 Durability on road trials
When a preformed road marking material to be used for permanent road marking is tested
according to 5.3.2, the road marking product shall be exposed to at least roll-over class P1 of
prEN 1824:2018, Table 3. In the case of road trial with studded tyres, class P0 applies and the
actual value of wheel passages (to the nearest thousand wheel passages) shall be stated in the
test report.
For the requirements of the preformed road marking material specified in 4.2, the results are
expressed in terms of the respective class in EN 1436:2018 (with the exception of the colour,
for which pass/fail criteria is used) for the corresponding roll-over class (P) and accompanied
by studded tyres (Y/N).
4.3.3 Durability on wear simulator - turntable
When a preformed road marking material to be used for permanent road marking is tested
according to 5.3.3, the road marking product shall be exposed to at least traffic class P4 of
EN 13197:2011+A1:2014, Table 4.
For the requirements of the preformed road marking material specified in 4.2, the results are
expressed in terms of the respective class in EN 1436:2018 (with the exception of the colour
for which pass/fail criteria is used) for the corresponding roll-over class (P).
4.4 Technical Characteristics - Resistance to UV exposure
UV resistance shall be checked in accordance with 5.4. The chromaticity coordinates of
preformed road marking after UV exposure shall comply with the region for white road
markings or with region Y1 or Y2 for yellow road markings of Table 6 in EN 1436:2018,
respectively for white and yellow preformed road marking.
The preformed road marking materials shall be classified in accordance with Table 1, where
Δβ is the difference between the luminance factor before and after UV exposure.
Table 1 — Classes of UV resistance
Colour Class Δβ
White and yellow UV0 No value requested
White and yellow UV2 ≤ 0,10
5 Testing, assessment and sampling
5.1 Preparation of test samples
The preformed road markings are applied to a flat substrate, or on the road, or on samples for
the wear simulator, according to the recommendations of the manufacturer.
If not specified in the relevant test method, samples representative of the material shall be
taken from storage in accordance with EN 13459:2011.
In some cases, it can be necessary to take samples at interim stages of the manufacturing
process, e.g. before release coatings are applied that are needed for packaging and transport,
but do not remain on the product during use.
Smaller representative samples, of sufficient quantity to carry out all the tests required, could
be taken from the larger samples.
For preformed materials cut in symbols, legends or other special shapes, where lengths of at
least 1 m cannot be sampled, an equivalent area of at least 0,75 m , with a minimum width of
0,15 m and a length suitable for the tests mentioned in 5.2 shall be sampled.
5.2 Test methods for the essential characteristics
5.2.1 General
The requirements of 4.2 apply to the products as they leave the manufacturing site. They can
be applied on samples in a laboratory, but also on samples applied on the road or wear
simulator.
NOTE The parameters measured on new samples in a laboratory are not to be confused with the
initial measurements, applied for durability purpose, which are carried out in accordance with

5.2.2 Day-time Visibility (Reflection in daylight or under road lighting)
Day-time visibility may be measured either by:
−2 −1
a. the coefficient of luminance under diffuse illumination (Qd), expressed in mcd·m ·lx
according to EN 1436:2018, Annex A;
or
b. the luminance factor (β), according to EN 1436:2018, Annex C.
5.2.3 Night-time Visibility (Retroreflection under vehicle headlamp illumination)

EN 1436:2018, Annex B;
b. coefficient of retroreflected luminance with wetness (RW) in accordance with
EN 1436:2018, Annex B;
c. coefficient of retroreflected luminance during rain (RR) in accordance with
EN 1436:2018, Annex B.
NOTE The test condition b.) and c.) is not applicable for newly applied road markings, when the
surface is hydrophobic so that water forms puddles on the surface. The hydrophobic surface property
normally disappears a few weeks after a road marking is applied. See 5.1 for the preparation of test
samples.
5.2.4 Day-time Visibility (Chromaticity coordinates)
Chromaticity in daylight shall be tested in accordance with EN 1436:2018, Annex C.
5.2.5 Night-time Visibility (Chromaticity coordinates)
Chromaticity in nighttime for retroreflected light shall be tested in accordance with
EN 1436:2018, Annex C.
5.2.6 Skid resistance SRT value (only for non-structured road marking products)
Skid resistance shall be tested in accordance with EN 1436:2018, 4.5.
5.3 Test methods for durability
5.3.1 General
Test methods for determining the following performance characteristics of the preformed
road markings are stated in 5.2.2 – 5.2.6:
— Retroreflection under vehicle headlamp illumination (see 4.2.2):
— coefficient of retroreflected luminance R expressed as class R on dry conditions (only
L

5.3.2 Durability on road trials
Durability on road trials shall be tested in accordance with prEN 1824:2018. Testing
conditions shall be reported as in prEN 1824:2018, Clause 8, for the required roll-over classes
(P or T). For studded tyres roll-over class P0 the report shall include the actual value of wheel

Testing conditions shall be reported as in EN 13197:2011+A1:2014, Clause 9 for the required
traffic classes (P).
5.4 Test method for resistance to UV exposure
The samples shall be tested in accordance with EN ISO 4892-3:2016 for 168 h under lamp type
II (UVB - 313) in cycles of 8 h of radiation at (60 ± 2) °C and 4 h of condensation at (50 ± 2) °C.
6 Assessment and verification of constancy of performance — AVCP
6.1 General
The compliance of preformed road marking with the requirements of this standard and with
the performances declared by the manufacturer in the DoP shall be demonstrated by:
— determination of the product type;
— factory production control by the manufacturer, including product assessment.
The manufacturer shall always retain the overall control and shall have the necessary means
to take responsibility for the conformity of the product with its declared performance(s).
6.2 Assessment of performance
6.2.1 General
All performances related to characteristics included in this standard shall be determined when
the manufacturer intends to declare the respective performances unless the standard gives
provisions for declaring them without performing tests. (e.g. use of previously existing data,
CWFT and conventionally accepted performance).
Assessment previously performed in accordance with the provisions of this standard, may be
taken into account provided that they were made to the same or a more rigorous test method,
under the same AVCP system on the same product or products of similar design, construction
and functionality, such that the results are applicable to the product in question.
NOTE Same AVCP system means testing by an independent third party, under the responsibility of
a notified product certification body.
For the purposes of assessment, the manufacturer's products may be grouped into families,
where it is considered that the results for one or more characteristics from any one product
within the family are representative for the same characteristics for all products within that
same family.
Products may be grouped in different families for different characteristics.
Reference to the assessment method standards should be made to allow the selection of a
suitable representative sample.
In addition, the determination of the product type shall be performed for all characteristics
included in the standard for which the manufacturer declares the performance:
— at the beginning of the production of a new or modified preformed road marking (unless
a member of the same product range), or
— at the beginning of a new or modified method of production (where this may affect the
stated properties); or
they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the
preformed road marking design, in the raw material or in the supplier of the components, or
in the method of production (subject to the definition of a family), which would affect
significantly one or more of the characteristics.
Where components are used whose characteristics have already been determined, by the
component manufacturer, on the basis of assessment methods of other product standards,
these characteristics need not be re-assessed. The specifications of these components shall be
documented.
Products bearing regulatory marking in accordance with appropriate harmonized European
specifications may be presumed to have the performances declared in the DoP, although this
does not replace the responsibility on the preformed road marking manufacturer to ensure
that the preformed road marking as a whole is correctly manufactured and its component
products have the declared performance values.
6.2.2 Test samples, testing and compliance criteria
The number of samples of preformed road marking to be tested/assessed shall be in
accordance with Table 2

6.2.3 Test reports
The results of the determination of the product type shall be documented in test reports. All
test reports shall be retained by the manufacturer for at least 10 years after the last date of
production of the preformed road marking to which they relate.
6.3 Verfification of constancy of performance Factory production control (FPC)
6.3.1 Factory production control (FPC)
The manufacturer shall establish, document and maintain an FPC system to ensure that the
products placed on the market comply with the declared performance of the essential
characteristics.
The FPC system shall consist of procedures, regular inspections and tests and/or assessments
and the use of the results to control raw and other incoming materials or components,
equipment, the production process and the product.
All the elements, requirements and provisions adopted by the manufacturer shall be
documented in a systematic manner in the form of written policies and procedures.
This factory production control system documentation shall ensure a common understanding
of the evaluation of the constancy of performance and enable the achievement of the required
product performances and the effective operation of the production control system to be
checked. Factory production control therefore brings together operational techniques and all
measures allowing maintenance and control of the compliance of the product with the
declared performances of the essential characteristics.
In case the manufacturer has used shared or cascading product type results, the FPC shall also
include th
