COMMISSION 
Proposal for a Council Directive on the approximation of the laws of the Member States relating to the spray-
suppression devices of certain categories of motor vehicle and their trailers 
COM(87) 132 final 
(Submitted by the Commission to the Council on 12 August 1987) 
(87/C 265/01) 
THE COUNCIL OF THE EUROPEAN COMMUNITIES, 
Having regard to the Treaty establishing the European 
Economic Community, and in particular Article 100A 
thereof, 
Having regard to the proposal from the Commission, 
In cooperation with the European Parliament, 
Having regard to the opinion of the Economic and 
Social Committee, 
Whereas it is important to adopt measures with the 
aim of progressively establishing the internal market 
over a period expiring on 31 December 1992; whereas 
the internal market shall comprise an area without 
internal frontiers in which the free movement of goods, 
persons, services and capital is ensured; 
Whereas the technical requirements which certain 
vehicle categories must satisfy pursuant to national laws 
relate inter alia to the spray-suppression devices of 
motor vehicles and their trailers; 
Whereas these requirements differ from one Member 
State to another; whereas it is therefore necessary that 
all Member States adopt the same requirements either 
in addition to or in place of their existing rules in order, 
in particular, to allow the EEC type-approval procedure 
which was the subject of Council Directive 70/156/EEC 
of 6 February 1970 on the approximation of the laws 
of the Member States relating to the type-approval of 
motor vehicles and their trailers (l), as last amended by 
the Act of Accession of Spain and Portugal, to be 
introduced in respect of each type of vehicle; 
(') OJ No L 42, 23. 2. 1970, p. 1. Whereas, with a view to ensuring road safety, .it is 
considered important that all vehicles in higher weight 
categories and with a certain minimum design speed 
should be equipped with efficient spray-suppression 
devices in order to retain water and small objects 
thrown upwards and sideways from the vehicle tyres; 
whereas, for practical reasons, it is felt necessary to fix 
different deadlines for the application of the provisions 
of this Directive in respect of new type approvals, all 
new vehicles and all vehicles on the road; 
Whereas the approximation of national laws relating 
to motor vehicles entails the mutual recognition by 
Member States of the inspections carried out by each 
of them on the basis of common requirements, 
HAS ADOPTED THIS DIRECTIVE: 
Article 1 
1. Member States shall grant EEC component type-
approval for any type of device, hereinafter referred to 
as 'spray-suppression device', intended to prevent or 
limit the production of spray or the throwing-up of 
mud and stones, coming from tyres of moving vehicles, 
which satisfies the requirements of Annex II. 
2. A Member State which has granted EEC com­
ponent type-approval shall take the measures required 
to verify, in so far as is necessary and, if need be, in 
cooperation with the competent authorities of the other 
Member States, that production models conform to the 
approved type. For this purpose the Member State shall 
apply the provisions of Annex IV. 
No C 265/2 Official Journal of the European Communities 5. 10. 87 
Article 2 
Member States shall, for each spray-suppression device 
which they approve pursuant to Article 1, issue to the 
manufacturer or to his authorized representative an 
EEC component type-approval mark in conformity 
with the specimen in Appendix 3 to Annex II. 
Member States shall take all appropriate measures to 
prevent the use of marks liable to create confusion 
between spray-suppression devices which have been 
component type-approved pursuant to Article 1 and 
other devices. 
Article 3 
1. No Member State may prohibit the placing on 
the market of spray-suppression devices on grounds 
relating to their construction if they bear the EEC 
component type-approval mark. 
2. Nevertheless, a Member State may prohibit the 
placing on the market of spray-suppression devices 
bearing the EEC component type-approval mark which 
consistently fail to conform to the approved type. 
That Member State shall forthwith inform the other 
Member States and the Commission of the measures 
taken, specifying the reasons for its decision. The pro­
visions of Article 5 shall also apply. 
Non-conformity with the approved type, within the 
meaning of the first subparagraph, shall exist if the 
requirements of Annex II have not been respected. 
Article 4 
The competent authorities of each Member State shall, 
within one month, send the competent authorities of 
the other Member States copies of the component type-
approval certificates completed for each type of spray-
suppression device which they approve or refuse to 
approve. 
Article 5 
1. If the Member State which has granted EEC com­
ponent type-approval finds that a number of spray-
suppression devices bearing the same EEC component 
type-approval mark do not conform to the type which 
it has approved, it shall take the necessary measures to 
ensure that production models conform to the approved 
type. The competent authorities of that State shall 
advise those of the other Member States of the measures taken, which may extend to withdrawal of EEC com­
ponent type-approval. The said authorities shall take 
the same measures if they are informed by the com­
petent authorities of another Member State of such 
failure to conform. 
2. The competent authorities of the Member States 
shall within one month inform each other of any with­
drawal of EEC component type-approval by means 
of a copy of the component type-approval certificate, 
signed and dated and bearing in large letters the words 
'EEC TYPE-APPROVAL WITHDRAWN', and of the 
reasons for any such measure. 
3. If the Member State which has granted the EEC 
component type-approval disputes the alleged lack of 
conformity, the Member States concerned shall endeav­
our to settle the disagreement. The Commission shall 
be kept informed. Where necessary, it shall arrange for 
appropriate discussions with a view to arriving at a 
solution. 
Article 6 
Any decision taken pursuant to the provisions adopted 
in implementation of this Directive to refuse or with­
draw EEC component type-approval for spray-sup­
pression devices, to refuse this registration, or to pro­
hibit their placing on the market or their use, shall set 
out in detail the reasons on which it is based. Such 
decisions shall be notified to the party concerned, who 
shall at the same time be informed of the remedies 
available to him under the laws in force in the Member 
States and of the time limits fixed for availing himself 
of such remedies. 
Article 7 
For the purposes of this Directive, 'vehicle' means any 
motor vehicle in categories N2 and N3 and trailers in 
categories 03 and 04, as defined in Annex I to Directive 
70/156/EEC, designed for use on the road, with or 
without bodywork, and with a maximum design speed 
exceeding 50 km/h. 
Article 8 
1. No Member State may refuse to grant EEC type-
approval or national type-approval in respect of a 
vehicle on grounds relating to its spray-suppression 
devices if the latter bear the EEC component type-
approval mark and if they have been fitted pursuant to 
the provisions of Annex III. 
2. No Member State may refuse or prohibit the sale, 
registration, entry into service or use of any vehicle on 
grounds relating to its spray-suppression devices if these 
5. 10. 87 Official Journal of the European Communities No C 265/3

ANNEX 1 
DEFINITIONS AND GENERAL REQUIREMENTS 
Definitions 
1.1. Spray-suppression device 
A device intended to retain water thrown upwards by vehicle tyres, to reduce the pulverization thereof 
and to deflect same towards the road surface at a low speed, at the same time reducing the risk of 
danger to other road users created by small objects (stones, mud, etc.) being thrown away from the 
vehicle by its tyres. 
1.2. Wheelguard (mudguard) 
The part of the spray-suppression device intended to trap the water, etc., thrown up by the tyre and 
to direct it towards the ground. Mudguards may form an integral part of the vehicle bodywork. 
1.3. Rain flap 
The flexible part of the spray-suppression device mounted vertically behind the wheel, on the lower 
part of the chassis or on the mudguard.

Appendix 1 
TESTS ON CATEGORY I SPRAY-SUPPRESSION DEVICES 
1. Principle 
The aim of this test is to quantify the ability of a spray suppressor to retain the water directed against 
it by a series of jets. The test assembly is intended to reproduce the conditions under which the equipment 
is to function when fitted to a vehicle as regards the volume and speed of the water thrown up by the 
ground contact patch of the tyre. 
2. Equipment 
See figure 8 for a description of the test assembly, based on British Standard AU 200 1984, as adapted 
by Amendment No 1 (1986). Tests must be conducted in a draught-free environment. 
3. Procedure 
3.1. Secure a 500 ( + 0/ —5) mm wide, 750 mm long sample of the equipment to be tested, or attach the 
device to the vertical frame of the testing equipment, making sure that the sample or device lies well 
within the limits of the collector, and that no mounting is able to deflect the water, either before or 
after its impact. 
3.2. Set the water flow rate at 0,675 (± 0,01) litres per second and direct at least 90 litres onto the sample 
from a horizontal distance of 500 (± 2) mm (figure 8). 
3.3. Allow the water to trickle from the sample into the collector and calculate the percentage (difference) 
between the quantity of water collected and the quantity of water sprayed. 
3.4. Repeat the test five times and calculate the average percentage amount of water collected. 
4. Results 
4.1. The calculated average percentage of water collected during the five tests shall not be less than 65% of 
the amount of water directed onto the device. 
4.2. If the highest and lowest percentages of water recovered depart from the average percentage by more 
than 5 %, the test will not be valid and shall be repeated. 
If even in this second test the highest and lowest percentages of water recovered again depart from the 
average percentage by more than 5 %, and/or if the average value, does not satisfy the requirements of 
4.1 of this Appendix, approval is refused. 
Appendix 2 
TESTS ON CATEGORY II SPRAY-SUPPRESSION DEVICES (AIR/WATER SEPARATORS) 
1. Secure the device in accordance with 7.2.2 of Annex III, but at a distance of 0,85 R from a vertical line 
passing through the centre of the wheel, at 75 mm from a plane parallel to the wheel in the straight-
ahead position. 
2. Turn the wheel at an angular velocity equivalent to a speed of 50 km/h and pass the wheel through the 
device 500 times by simulating a steering motion of approximately 30°. 
3. Examine the device and check that any openings for the tyre close automatically when the wheel returns 
to the straight-ahead position. 
Check whether the tyre has clearly deteriorated.

5.3.5. 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 (b)). 
5.3.6. Rain flaps shall 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 50 mm above the lower edge of the flaps. 
5.3.7. The whole of the front surface of the flap must be fitted with spray suppression material complying 
with the specifications set out in Annex II. 
6. Spray reduction devices for rigid axles (see 4.2 above) 
6.1. Outer valances 
Preferably, outer valances should cover the area from the bodywork above, down to the side of the 
tyres and around the tyre circumference, from the front of the (first) tyre to the guards or flaps 
behind the (last) tyre. 
The following minimum requirements apply: 
6.1.1. Height: The outer valance must cover the distance between the lower part of the vehicle's structure 
and the horizontal plane tangential to the tip of the tyre(s). Its depth shall not be less than 100 mm. 
6.1.2. Length: The outer valance must cover the distance between the outer edge of the flap (at the rear) 
and the vertical plane tangential to the front of the tyre (figure 5 (b)). If in implementation of 5.3.5 
there are no rain flaps behind each wheel, in the case of multiple axles, the valance must cover the 
distance between the outer edge of the flap and the vertical plane tangential to the front of the tyre 
on the wheel on the first axle (figure 5 (a)). 
6.1.3. The entire inner surface of the outer valance must be fitted with a spray-reduction device complying 
with the specifications set out in Annex II.

ANNEX IV 
CONFORMITY OF PRODUCTION, GENERAL SPECIFICATIONS, CESSATION OF PRODUCTION 
1. Conformity of production 
1.1. Any device bearing the EEC type-approval mark shall conform with the type approved. The authority 
issuing the type-approval mark shall keep one sample which, together with the type-approval form, may 
be used to establish whether the devices marketed which bear the type-approval mark meet this 
requirement. 
1.2. A type of device shall be defined by the model and descriptive documents lodged at the time of 
application for type-approval. Devices whose characteristics are identical with those of the pattern 
device and whose other components do not differ from those of the pattern device except for variants 
not effecting the properties referred to in this annex may be considered to belong to the same type. 
1.3. The manufacturer shall carry out routine checks in order to guarantee the conformity of production of 
the product type approved. 
To this end the manufacturer shall: 
— 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 shall be made available for inspection by the competent 
authorities for at least one year. 
5. 10. 87 Official Journal of the European Communities No C 265/15 
1.4. The competent authorities may also conduct spot checks. 
1.5. Conformity of production with the type approved device shall be checked under the conditions and in 
accordance with the methods provided for in Annex II. 
Manufacturers shall, at the request of the authority which granted type approval, place at its disposal 
devices of the type previously approved, for the purpose of conformity tests or checks. 
1.6. Conformity of production exists if nine out of 10 specimens chosen at random satisfy the requirements 
of point 4 of Annex II (Appendix 1). 
1.7. If the condition specified in 1.6 is not satisfied, a further 10 specimens chosen at random must be 
examined. 
The average of all measurements taken must be in conformity with the specifications of point 4 of 
Annex II (Appendix 1), and no individual measurement must be less than 95% of the value specified. 
2. General specifications 
2.1. Manufacturers or their agents holding a type-approval shall not sell the product unless this is accompanied 
by a technical note containing the fitting requirements specific to it—as set out in Annex III. Any further 
vendor shall be required to act in the same manner. 
2.2. Devices of this type shall be constructed in such a way that they shall operate properly and continue to 
do so when used normally on wet roads. Moreover, they shall incorporate no structural or manufacturing 
defect detrimental to their proper functioning or behaviour. 
3. Cessation of production 
3.1. If the holder of a type-approval entirely ceases production of a device he shall immediately inform the 
competent authority thereof.
