PART 1
Requirements for spray suppression devices
0. GENERAL
SPECIFICATIONS
0.1. Spray-suppression
devices
must
be
constructed
in
such
a
way
that
they
operate
properly
when
used
normally
on
wet roads. Moreover, they must incorporate no structural or manufacturing defect detrimental to their proper
functioning or behaviour.
1. TESTS
TO
BE
CARRIED
OUT
1.1. Depending
on
their
physical
operating
principle
spray-suppression
devices
are
subjected
to
the
relevant
tests
as
described in Parts 2 and 3 and must deliver the results required in point 5 of those Parts.
2. APPLICATION
FOR
EC
COMPONENT
TYPE-APPROVAL
2.1. The application for EC component type-approval pursuant to Article 7 of Directive 2007/46/EC of a type of spray-
suppression device shall be submitted by the manufacturer.
2.2. A
model
for
the
information
document
is
set
out
in
Part
1
of
Annex
II.
2.3. The following shall be submitted to the technical service responsible for conducting the type-approval tests:
Four samples: three of which are for tests and a fourth is to be kept by the laboratory for any subsequent
verification. The test laboratory may require further samples.
2.4. Markings
2.4.1. Each sample must be clearly and indelibly marked with the trade name or mark and an indication of the type and
include a space that is large enough for the EC component type-approval mark.
2.4.2. A symbol ‘A’ for devices of the energy-absorption type or ‘S’ for devices of the air/water separator type shall be
added to the approval mark in accordance with point 1.3 of the Appendix of Annex VII to Directive 2007/46/EC.
PART 2
Tests on spray-suppression devices of the energy-absorber type
1. PRINCIPLE
The aim of this test is to quantify the ability of a device to retain the water directed against it by a series of jets.
The test assembly is intended to reproduce the conditions under which the device is to function when fitted to a
vehicle as regards the volume and speed of the water thrown up from the ground by the tyre tread.
2. EQUIPMENT
See Figure 8 in Annex VI for a description of the test assembly.
3. TEST
CONDITIONS
3.1. The
tests
must
be
carried
out
in
a
closed
room
with
a
still-air
environment.
3.2. The ambient temperature and the temperature of the test pieces must be 21 (± 3) °C.
3.3. De-ionised
water
is
to
be
used.
3.4. The test pieces must be prepared for each test by wetting.
4. PROCEDURE
4.1. Secure a 500 (+ 0/– 5) mm wide 750 mm high sample of the equipment to be tested to the vertical plate of the
testing equipment, making sure that the sample lies well within the limits of the collector, and that no obstacle is
able to deflect the water, either before or after its impact.

PART 3
Test on spray-suppression devices of the air/water separator type
1. PRINCIPLE
This test is intended to determine the effectiveness of a porous material intended to retain the water with which it
has been sprayed by means of a pressurised air/water pulveriser.
The equipment used for the test must simulate the conditions to which the material would be submitted, with
regard to the volume and speed of the water sprays produced by the tyres, if it were fitted to a vehicle.
2. EQUIPMENT
See Figure 9 in Annex VI for a description of the test assembly.
3. TEST
CONDITIONS
3.1. The
tests
must
be
carried
out
in
a
closed
room
with
a
still-air
environment.
3.2. The ambient temperature and the temperature of the test pieces must be 21 (± 3) °C.
3.3. De-ionised
water
must
be
used.
3.4. The test pieces must be prepared for each test by wetting.
4. PROCEDURE
4.1. Secure a 305 × 100 mm sample vertically in the test assembly, check that there is no space between the sample
and the upper curved plate and that the tray is properly in position. Fill the pulveriser tank with 1 ± 0,005 litres of
water and place this as described in the diagram.
4.2. The
pulveriser
must
be
regulated
as
follows:
pressure (at pulveriser): 5 bar + 10 %/– 0 %
flowrate: 1 litre/minute ± 5 seconds
pulverisation: circular, 50 ± 5 mm in diameter at 200 ± 5 mm from the sample, nozzle 5 ± 0,1 mm in diameter.
4.3. Pulverise until there is no more water mist and note the time taken. Let the water flow out of the sample on to the
tray for 60 seconds and measure the volume of water collected. Measure the quantity of water left in the pulveriser
tank. Calculate the percentage by volume of water collected versus the volume of water pulverised.

4.4. Carry out the test five times and calculate the average percentage of the quantity collected. Check before each test
that the tray, pulveriser tank and measuring vessel are dry.
5. RESULTS
5.1. The
average
percentage
calculated
in
point
4.4
must
be
85
%
or
higher.
5.2. If within a series of five tests the highest and lowest percentages of water collected depart from the average
percentage by more than 5 %, the series of five tests must be repeated. If within a second series of five tests the
highest and lowest percentages of water recovered again depart from the average percentage by more than 5 %,
and if the lower value does not satisfy the requirements of point 5.1, type-approval shall be refused.
5.3. Where the vertical position of the device influences the results obtained, the procedure described in points 4.1 to
4.4 must be repeated in the positions giving the highest and lowest percentages of water collected; the
requirements of point 5.2 remain in force.
The requirement of point 5.1 remains in force in order to give the results of each test.

ANNEX IV
Requirements for type-approval of vehicles with regard to their spray suppression systems
0. GENERAL
0.1. Category
N
and
O
vehicles,
with
the
exception
of
off-road
vehicles
as
defined
in
Annex
II
to
Directive
2007/46/EC, shall be constructed and/or fitted with spray suppression systems in such a way as to meet the
requirements laid down in this Annex. In the case of chassis/cab vehicles, these requirements may only be
applied to the wheels covered by the cab.
For vehicles of category N 1 and N 2 with a permissible maximum laden mass not exceeding 7,5 tonnes, the
requirements of Council Directive 78/549/EEC ( 1 ) may be applied as alternative to the requirements of this
Regulation at the request of the manufacturer.
0.2.
The requirements of this Annex relating to spray-suppression devices, as defined in Article 2(4), are not
mandatory for categories N, O 1 and O 2 vehicles with a permissible maximum laden mass not exceeding 7,5
tonnes, chassis/cab vehicles, unbodied vehicles or vehicles on which the presence of spray-suppression devices
would be incompatible with their use. However, if such devices are fitted to those vehicles, they must conform to
the requirements of this Regulation.
1.
A vehicle representative of the vehicle type to be approved, fitted with its spray-suppression system, must be
submitted to the technical service conducting the approval tests.
GENERAL REQUIREMENTS
2. AXLES
2.1. Retractable
axles
Where a vehicle is fitted with one or more retractable axles, the spray-suppression system must cover all the
wheels when the axle is lowered and the wheels in contact with the ground when the axle is raised.
2.2. Self-tracking
axles
For the purpose of this Regulation, a self-tracking axle of the ‘pivot steering’ type is considered to be, and treated
as, an axle fitted with steered wheels.
Where a vehicle is fitted with a self-tracking axle, the spray-suppression system must satisfy the conditions
applicable to non-steered wheels if mounted on the pivoting part. If not mounted on that part it must satisfy the
conditions that are applicable to steered wheels.
3. POSITION
OF
OUTER
VALANCE
The distance ‘c’ between the longitudinal plane tangential to the outer tyre wall, apart from any tyre bulge near
the ground, and the inner edge of the valance must not exceed 100 mm (Figures 1a and 1b of Annex VI).
4. STATE
OF
VEHICLE
For the checking of compliance with this Regulation the vehicle must be in the following state:
(a) it must be unladen and with the wheels in the straight-ahead position;
(b) in the case of semi-trailers, the loading surfaces must be horizontal;
(c) the tyres must be inflated to their normal pressure.
5. SPRAY-SUPPRESSION
SYSTEMS
5.1. The
spray-suppression
system
must
meet
the
specifications
set
out
in
point
6
or

5.2.
The spray-suppression system for non-steered or self-steered wheels that are covered by the bodywork floor, or
by the lower part of the load platform, must meet either the specifications set out in point 6 or 8 or else those
in point 7.
SPECIFIC REQUIREMENTS
6. Requirements
concerning
energy-absorption
spray
suppression
systems
for
axles
fitted
with
steered
or
self-
steering or non-steered wheels.
6.1. Mudguards
6.1.1. The mudguards must cover the zone immediately above, ahead and behind the tyre or tyres in the following
manner:
(a) in the case of a single or multiple axle, the forward edge (C) must extend forwards to reach a line O-Z where
Θ (theta) is no more than 45° above the horizontal.
The rearmost edge (Figure 2 of Annex VI) must extend downwards in such a way as not to be more than
100 mm above a horizontal line passing through the centre of the wheel;
(b) in the case of multiple axles the angle Θ relates only to the foremost axle and the requirement relating to the
height of the rearmost edge applies only to the rearmost axle;
(c) the mudguard must possess a total width ‘q’ (Figure 1a of Annex VI) at least adequate to cover the width of
the tyre ‘b’ or the entire width of two tyres ‘t’ in the case of twin wheels, account being taken of the extremes
for the tyre/wheel unit specified by the manufacturer. Dimensions ‘b’ and ‘t’ shall be measured at hub height,
excluding any markings, ribs, protective bands, etc., on the tyre walls.
6.1.2. The front side of the rear part of the mudguard must be fitted with a spray-reduction device complying with the
specifications set out in Part 2 of Annex III. This material must cover the inside of the mudguard up to a height
determined by a straight line running from the centre of the wheel and forming an angle of at least 30° with the
horizontal (Figure 3 of Annex VI).
6.1.3. If the mudguards are made up of several components, when fitted, they must not incorporate any aperture
enabling spray to exit while the vehicle is in motion. This requirement is deemed to be met if, when the vehicle
is either laden or unladen, any radial jet running outwards from the wheel centre over the entire width of the
tyre running surface and within the range covered by the mudguard always strikes against a part of the spray
suppression system.
6.2. Outer
valances
6.2.1. In the case of single axles, the lower edge of the outer valance may not be situated beyond the following
distances and radii, as measured from the centre of the wheel, except at the lowest extremities that may be
rounded (Figure 2 of Annex VI).
Air suspension:
(a) Axles fitted with steered wheels or self-steering wheels:
9
From the front edge (towards the front of the vehicle) (tip C)
= R v ≤ 1,5 R
To the rear edge (towards the rear of the vehicle) (tip A)
;
(b) Axles fitted with non-steered wheels:
9
From the front edge (tip C)
= R v ≤ 1,25 R
To the rear edge (tip A)
;
Mechanical suspension
(a) general case} R v ≤ 1,8 R
(b) non-steered wheels for vehicles with a technically permissible laden mass more than 7,5 t} R v ≤ 1,5 R
where R is the radius of the tyre fitted to the vehicle, and Rv the distance, expressed as a radius, at which the
lower edge of the outer valence is situated.

6.2.2. In the case of multiple axles the requirements laid down in point 6.2.1 do not apply between the vertical
transversal planes passing through the centre of the first and the last axles where the outer valance may be
straight in order to ensure the continuity of the spray suppression system. (Figure 4 of Annex VI).
6.2.3. The distance between the uppermost and the lowermost points of the spray suppression system (mudguard and
outer valance) measured in any cross section perpendicular to the mudguard (see Figures 1b and 2 in Annex VI)
must extend to not less than 45 mm at all points behind a vertical line passing through the centre of the wheel
or the first wheel in the case of multiple axles. This dimension may be gradually reduced in front of this line.
6.2.4. No openings enabling spray to emerge when the vehicle is moving are allowed in the outer valances or between
the outer valances and the other parts of the mudguards.
6.2.5. The requirements of points 6.2.3 and 6.2.4 may not be respected locally when the valance is composed by
different elements with relative movement.
6.2.6. Tractors for semi-trailers with a low chassis, namely those which may have a height of coupling face (defined in
point 6.20 of standard ISO 612 of 1978) equal to or less than 1 100 mm, may be designed in such a way as to
be exempted from the requirements of points 6.1.1(a), 6.1.3 and 6.2.4. In this regard, mudguards and valances
may not cover the area immediately above the tyres of the rear axles, when these tractors are coupled to a semi-
trailer, in order to avoid the spray-suppression system being destroyed. However, the mudguards and valances of
these vehicles must conform to the requirements of the above points, in sectors more than 60° from the vertical
line passing through the centre of the wheel, in front and behind these tyres.
Those vehicles must therefore be designed in such a way as to meet the requirements set out in the first
paragraph when they are operated without a semi-trailer.
In order to be able to meet those requirements, mudguards and valances may, for example, comprise a
removable part.
6.3. Rain
flaps
6.3.1. The width of the flap must fulfil the requirement for ‘q’ in point 6.1.1(c), except for any part of the flap that is
contained within the mudguards. In such cases this part of the flap must be at least equal in width to the tread of
the tyre.
The width of the part of the rain flaps positioned beneath the mudguard must satisfy the condition laid down in
this paragraph with a tolerance of ± 10 mm at each side.
6.3.2. The
orientation
of
the
flap
must
be
basically
vertical.
6.3.3. The maximum height of the bottom edge must not exceed 200 mm (Figure 3 of Annex VI).
This distance is increased to 300 mm in the case of the last axle where the radial distance of the lower edge of
the outer valancing, Rv, does not exceed the dimensions of the radius of the tyres fitted to the wheels on that
axle.
The maximum height of the bottom edge of the rain flap in relation to the ground, may be raised to 300 mm if
the manufacturer deems it technically appropriate with regard to the suspension characteristics.
6.3.4. The rain flap must not be more than 300 mm from the rearmost edge of the tyre, measured horizontally.
6.3.5. In the case of multiple axles where distance d between the tyres on adjacent axles is less than 250 mm, only the
rear set of wheels must be fitted with rain flaps. There must be a rain flap behind each wheel when distance d
between the tyres on adjacent axles is at least 250 mm (Figure 4 of Annex VI).
6.3.6. Rain flaps must not be deflected by more than 100 mm towards the rear under a force of 3 N per 100 mm of
flap width, applied to a point located 50 mm above the lower edge of the flaps.
6.3.7. The whole of the front face of the part of the rain flap having the minimum dimensions required must be fitted
with a spray-suppression device that meets the specifications set out in Part 2 of Annex III.

6.3.8. No openings enabling spray to emerge are allowed between the lower rear edge of the mudguard and the rain
flaps.
6.3.9. Where the spray-suppression device meets the specifications relating to rain flaps (point 6.3), no additional rain
flap is required.
7.

certain axles that are fitted with non-steered or self-steering wheels (see point 5.2).
7.1. Mudguards
7.1.1. Mudguards must cover the zone immediately above the tyre or tyres. Their front and rear extremities must
extend at least to the horizontal plane that is tangent to the upper edge of the tyre or tyres (Figure 5 of Annex
VI). However, the rear extremity may be replaced by the rain flap, in which case this must extend to the upper
part of the mudguard (or equivalent component).
7.1.2. All of the inner rear part of the mudguard must be fitted with a spray-suppression device that meets the
requirements set out in Part 2 of Annex III.
7.2. Outer
valances
7.2.1. In the case of single or multiple axles where the distance between the adjacent tyres is at least 250 mm, the outer
valance must cover the surface extending from the lower to the upper part of the mudguard up to a straight line
formed by the tangent to the upper edge of the tyre or tyres and lying between the vertical plane formed by the
tangent to the front of the tyre and the mudguard or rain flap located behind the wheel or wheels (Figure 5b of
Annex VI).
In the case of multiple axles an outer valance must be located by each wheel.
7.2.2. No openings enabling spray to emerge are allowed between the outer valance and the inner part of the
mudguard.

8.2.2. In the case of single or multiple axles where the distance between the tyres on adjacent axles exceeds 300 mm,
the lower edge of the spray-suppression device fitted to the outer valance must have the following maximum
dimensions and radii, starting from the centre of the wheel (Figures 6 and 7 of Annex VI):
(a) Axles fitted with steered wheels or self-steering wheels:
9
from the front edge (towards the front of the vehicle) (tip C at 30°)
= R v ≤ 1,05 R
to the rear edge (towards the rear of the vehicle) (tip A at 100 mm)
(b) Axles fitted with non-steered wheels:
; 9
from the front edge (tip C at 20°)
=
to the rear edge (tip A at 100 mm)
; R v ≤ 1,00 R
where
R = is the radius of tyre fitted to the vehicle;
R v = the radial distance from the lowest edge of the outer valance to the centre of the wheel.
8.2.3. In the case of multiple axles where the distance between the tyres on adjacent axles does not exceed 300 mm,
the outer valances located in the inter-axle spaces must follow the path specified in point 8.1.3, and must extend
downwards in such a way as not to be more than 100 mm above a horizontal straight line passing through the
wheel centres (Figure 7 of Annex VI).
8.2.4. The depth of the outer valance must extend to not less than 45 mm, at all points behind a vertical line passing
through the centre of the wheel. This depth may be gradually reduced in front of this line.
8.2.5. No openings enabling spray to emerge are allowed in the outer valances or between the outer valances and the
mudguards.
8.3. Rain
flaps
8.3.1. Rain
flaps
must:
(a) comply with point 6.3 (Figure 3 of Annex VI); or
(b) comply with points 6.3.1, 6.3.2, 6.3.5, 6.3.8 and 8.3.2 (Figure 6 of Annex VI).

8.3.2.2. The spray-suppression device must be at least 100 mm deep.
8.3.2.3. Apart from the lower part, which includes the spray-suppression device, the rain flap as referred to in point
8.3.1(b) must not bend by more than 100 mm towards the rear under the effect of a force of 3 N per 100 mm
of width of the rain flap measured at the intersection of the rain flap with the spray-suppression device in its
working position, applied at a distance of 50 mm above the lower edge of the rain flap.
8.3.3. The rain flap must not be more than 200 mm from the rearmost edge of the tyre, measured horizontally.
9.
In the case of multiple axles, the spray-suppression system of one axle, which is not the furthest back, may not
need to cover the entire width of the tread of the tyre when there is, locally, the possibility of interference
between the spray-suppression system and the structure of the axles or of the suspension or of the undercarriage.

ANNEX V
Conformity of production and cessation of production
1. Conformity
of
production
1.1. Any spray-suppression device bearing the EC component type-approval mark must conform to the type that has
been approved. The authority issuing the EC type-approval mark keeps one sample which, together with the EC
component type-approval certificate, may be used to establish whether the devices marketed which bear the EC
component type-approval mark meet the stated requirements.
1.2. A type of device is defined by the model and descriptive documents lodged at the time of application for EC
component type-approval. Devices whose characteristics are identical to those of the pattern device and whose other
components do not differ from those of the pattern device except for variants not affecting the properties referred to
in this Annex may be considered as belonging to the same type.
1.3. The manufacturer carries out routine checks in order to guarantee the conformity of production of the type that has
been approved.
To this end the manufacturer must either have available a laboratory which is sufficiently well-equipped for the
execution of the essential tests, or have the production-conformity tests carried out by an approved laboratory.
The results of the production conformity checks are made available for inspection by the competent authorities for
at least 1 year.
1.4. The competent authorities may also conduct spot checks.
1.5. Conformity of production with the type of device that has been approved must be checked under the conditions and
in accordance with the methods provided for in Annex III.
At the request of the authorities which have granted component type-approval, manufacturers shall provide them
with devices of the type previously type-approved for the purpose of tests or conformity checks.
1.6. Devices are deemed to conform if 9 out of 10 samples chosen at random satisfy the requirements of point 4 of Part
2 and point 4 of Part 3 of Annex III.
1.7. If the condition specified in point 1.6 is not satisfied, a further 10 samples chosen at random must be examined.
The average of all measurements taken must be in conformity with the specifications of point 4 of Part 2 and point
4 of Part 3 of Annex III, and no individual measurement must be less than 95 % of the value specified.
2. Cessation
of
production
An EC component type-approval holder ceasing production must forthwith inform the competent authorities of
that fact.
