Council Directive 93/30/EEC of 14 June 1993 on audible warning devices for two- or three-wheel motor vehicles (repealed) (c. 30)

ANNEX II REQUIREMENTS APPLYING TO THE FITTING OF AUDIBLE WARNING DEVICES TO TWO- OR THREE-WHEEL MOTOR VEHICLES

2. REQUIREMENTS

2.1. All vehicles must be fitted with an audible warning device that has been component type-approved pursuant to this Directive or to Council Directive 70/388/EEC on the approximation of the laws of the Member States relating to audible warning devices for motor vehicles(1); however, mopeds equipped with an engine of no more than 0,5 kW, whose maximum design speed does not exceed 25 km/h, may be fitted either with an approved audible warning device or an unapproved mechanical warning device. In the latter case, the manufacturer must declare that such mechanical device complies with the requirement for that type of device in the Member State in which the low-performance moped is to be marketed.

2.2. The test voltage must be as laid down in section 3.3 in Annex I.

2.3. The sound pressure levels must be measured under the conditions laid down in section 3.2 in Annex I.

2.4. The A-weighted sound pressure level emitted by the device(s) fitted to the vehicle must be measured 7 m ahead of the vehicle, which must have been placed on a clear space, the ground being as smooth as possible and, in the case of direct-current audible warning devices, the engine of the vehicle being shut down.

2.5. The microphone for the measuring device must be located roughly in the median longitudinal plane of the vehicle.

2.6. The pressure level of the ambient noise and of the noise generated by the wind must be at least 10 dB(A) lower than the sound level to be measured.

2.7. The maximum sound pressure level must be sought within a segment lying between 0,5 and 1,5 m above ground level.

2.8. When measured under the conditions specified in sections 2.2 to 2.7 the maximum sound level value (section 2.7) of the audible warning under test must be at least:

(a)

75 dB(A) and at the most 112 dB(A) for mopeds;

(b)

80 dB(A) and at the most 112 dB(A) for motorcycles and tricycles developing a power of not more than 7 kW;

(c)

93 dB(A) and at the most 112 dB(A) for motorcycles and tricycles developing a power of more than 7 kW.
