(70/388/EEC)
THE COUNCIL OF THE EUROPEAN COMMUNITIES,
Having regard to the Treaty establishing the European Economic
Community, and in particular Article 100 thereof;
Having regard to the proposal from the Commission;Having regard to the Opinion of the European Parliament;
Having regard to the Opinion of the Economic and Social Committee;
Whereas the technical requirements which motor vehicles must satisfy
pursuant to national laws relate, inter alia, to their audible warning
devices;
Whereas those requirements differ from one Member State to another;
whereas it is therefore necessary that all Member States adopt the samerequirements either in addition to or in place of their existing rules, inorder, in particular, to allow the EEC type approval procedure whichwas the subject of the Council Directive(
1) 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 to be applied in respect
of eachtype of veh icle;
Whereas rules on audible warning devices should include requirements
relating not only to the fitting of such devices on vehicles but also to
the construction of such devices;
Whereas a harmonised type approval procedure for audible warning
devices makes it possible for eachMember State to ch eck compliancewithth e common requirements relating to construction and testing andto inform the other Member States of its findings by sending a copy of
the type approval certificate completed for each type of audible
warning device; whereas the placing of an EEC type approval markon all devices manufactured in conformity withth e approved typeobviates any need for technical checks on these devices in the otherMember States;
HAS ADOPTED THIS DIRECTIVE:
Article 1
1. EachMember State sh all approve any type of audible warning
device which satisfies the construction and testing requirements laiddown in item 1 of Annex I.
2. The Member State which has granted type approval shall take the
necessary measures to verify, in so far as is necessary and if need be inco-operation with the competent authorities in the other Member States,that production models conform to the approved type. Such verificationshall be limited to spot checks.
Article 2
Member States shall issue to the manufacturer, or to his authorised
representative, an EEC type approval mark which shall conform to themodel shown in item 1.4 of Annex I, for each type of audible warningdevice which they approve pursuant to Article 1.1970L0388 — EN — 28.07.1970 — 000.001 — 2
(1) OJ No L 42, 23.2.1970, p. 1.
▼B
Member States shall take all appropriate measures to prevent the use of
marks liable to create confusion between audible warning deviceswhich have been type approved pursuant to Article 1 and other devices.
Article 3
1. No Member State may prohibit audible warning devices from
being marketed on grounds relating to their construction or method ofoperation if those devices bear the EEC approval mark.
2. Nevertheless, this provision shall not prevent a Member State
from taking suchmeasures in respect of audible warning devicesbearing the EEC approval mark which, by their design, do not conformto the approved prototype.
That State shall inform the other Member States and the Commission
forthwith of the measures taken, specifying the reasons for its decision.The provisions of Article 5 shall also apply.
There shall be failure to conform to the approved prototype, within the
meaning of the first subparagraph, where the upper or lower limitspecified in item 1.2.1.6 of Annex I is not observed.
Article 4
The competent authorities of each Member State shall within one
month send to the competent authorities of the other Member States acopy of the type approval certificate for each type of audible warning
device which they approve or refuse to approve.
Article 5
1. If the Member State which has granted EEC approval finds that a
number of audible warning devices bearing the same approval mark donot conform to the type which it has approved, it shall take the neces-sary measures to ensure that production models conform to theapproved type. The competent authorities of that State shall advise
those of the other Member States of the measures taken, which may,
where necessary, extend to withdrawal of EEC approval. The saidauthorities shall take the same measures if they are informed by thecompetent authorities of another Member State of such failure toconform.
2. The competent authorities of the Member States shall within one
month inform each other of any withdrawal of EEC type approval, andof the reasons for such measures.
3. If the Member State which has granted EEC type approval
disputes the failure to conform notified to it, the Member Statesconcerned shall endeavour to settle the dispute. The Commission shall
be kept informed and shall, where necessary, hold appropriate consulta-
tions for the purpose of reaching a settlement.
Article 6
All decisions taken pursuant to the rules adopted in implementation of
this Directive and refusing or withdrawing approval for an audiblewarning device or prohibiting its marketing or use shall state in detailthe reasons on which they are based. A decision shall be notified to theparty concerned, who shall at the same time be informed of the reme-
dies available to him under the laws in force in the Member States and
of the time limits allowed for the exercise of such remedies.
Article 7
No Member State may refuse to grant EEC type approval or national
type approval of a vehicle on grounds relating to its audible warningdevice if that device bears the EEC approval mark and if it is fitted inaccordance withth e requirements laid down in item 2 of Annex I.1970L0388 — EN — 28.07.1970 — 000.001 — 3

1. EEC TYPE APPROVAL OF AN AUDIBLE WARNING DEVICE
1.1 The warning device shall emit a continuous sound.
1.2 The warning device shall have acoustic characteristics (frequency spec-
trum of the sound, level of sound pressure) and mechanical
characteristics such that it can satisfy the following tests, in the order
indicated.
1.2.1Measurement of sound level
1.2.1.1 The warning device shall be tested in a sufficiently silent and open
area(1) (ambient noise and wind noise at least 10 db (A) below the noise
being measured) or in an anechoic chamber; the microphone of the
measuring instrument shall be located in the direction in which the
subjective sound level is at a maximum and 2 m from the front surface
of the device, the microphone and the device being positioned at a
height of 1·20 m above ground level.
1.2.1.2 The measurements shall be made on the ‘A’ weighting scale of the IEC
(International Electrotechnical Commission) standard, by means of
sound-level meters conforming to the type described in Publications
179, 1st ed. (1965), of the International Electrotechnical Commission.
1.2.1.3 The device shall be supplied with a voltage of 6·5, 13 or 26 volts
measured at the terminal of the source of electric power, corresponding
respectively to a rated voltage of 6, 12 or 24 volts.

terminals and contacts, must be:
0·05 ohms for a 6 volt circuit
0·10 ohms for a 12 volt circuit0·20 ohms for a 24 volt circuit
1.2.1.5 The device shall be rigidly mounted, using the part or parts provided by
the manufacturer, on a support whose mass is at least ten times that of
the device and not less than 15 kg.
1.2.1.6 Under the above conditions, the subjective sound pressure level must be
not more than 118 dB (A) and not less than 105 dB (A).
1.2.1.7 The time lapse between the moment of activation and the moment at
which the sound reaches the minimum level laid down in item 1.2.1.6
above may not exceed 0·2 seconds, measured in an ambient temperature
of 20±5 ºC.
This provision shall apply in particular to pneumatically or electro-pneu-
matically operated devices.
1.2.1.8 Devices which are pneumatically or electro-pneumatically operated
must, with the pneumatic circuit arranged in accordance with the manu-
facturer's specification, have the same acoustic performance as that
required for electrically operated audible warning devices.
