COUNCIL DIRECTIVE of 17 September 1984 on the approximation of the laws of the Member States relating to the permissible sound power level of compressors (84/533/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 (1),

Having regard to the opinion of the European Parliament (2),

Having regard to the opinion of the Economic and Social Committee (3),

Whereas the 1973 and 1977 action programmes of the European Communities on the environment (4) reflect the importance of the problem of noise nuisance and in particular the need for action to regulate the worst noise sources;

Whereas disparity between the measures already applicable or in preparation in the various Member States concerning the limitation of the sound emission level of compressors creates unequal conditions of competition and thereby directly affect the functioning of the common market ; whereas it is therefore appropriate to proceed in that field with the approximation of laws for which Article 100 of the Treaty provides;

Whereas Council Directive 84/532/EEC of 17 September 1984 on the approximation of the laws of the Member States relating to common provisions for construction plant and equipment (5) has laid down, in particular, the procedure for EEC type-examination ; whereas it is necessary, pursuant to that Directive, to prescribe the harmonized requirements which each category of equipment must satisfy;

Whereas Council Directive 79/113/EEC of 19 December 1978 on the approximation of the laws of the Member States relating to the measurement of the sound level of construction plant and equipment (6), as amended by Directive 81/1051/EEC (7), laid down, in particular, the method which should be used for establishing the acoustic criteria for compressors;

Whereas owing to the effect of the noise emitted by compressors on the environment and, more particularly, on human well-being and health, it is necessary to bring about a progressive and appreciable reduction in the permissible sound power level of compressors;

Whereas it is important to be able to regulate the use of compressors in certain areas considered to be particularly sensitive so as to limit the nuisance caused by the airborne noise emitted by such compressors;

Whereas technical provisions must be adapted rapidly to technical advances ; whereas it is necessary to this end to provide for the application of the procedure set out in Article 5 of Directive 79/113/EEC,

HAS ADOPTED THIS DIRECTIVE:

Article 1

1. This Directive applies to the permissible sound power level of compressors used to perform work on civil engineering and building sites.

For the purposes of this Directive : "compressor" means any motor-driven device for circulating and compressing air other than the following two categories of device: - fans, i.e. devices producing air circulation at a positive pressure of not more than 1,1,

- vacuum pumps, i.e. devices or appliances for extracting air from an enclosed space at a pressure not exceeding atmospheric pressure.

Article 3

1. The approved bodies shall issue an EEC type-examination certificate for each type of compressor for which the sound power level of airborne noise, measured under the conditions set out in Annex I to Directive 79/113/EEC, as amended by Annex I to this Directive, does not exceed the permissible sound power levels given in the following table: >PIC FILE= "T0026405">

2. All applications for an EEC type-examination certificate in respect of the permissible sound power level of a compressor shall be accompanied by an information document conforming to the model shown in Annex II.

3. For each type of compressor which it certifies, the approved body shall complete all the sections of the EEC type-examination certificate conforming to the model given in Annex III to the framework Directive.

4. The period of validity of EEC type-examination certificates shall be limited to five years. This may be extended by five years provided that application is made during the 12 months preceding the expiry of the first five-year period.

However, at the end of a period of five years from notification of the Directive, EEC type-examination certificates shall cease to be valid unless they were issued for compressors which comply with the maximum level entering into force on that date.

5. By way of derogation from Article 19 (1) of the framework Directive, the advantages provided for in this Article shall, after a period of 5 1/2 years from notification of the Directive, no longer be available for compressors supplied with certificates of conformity drawn up on the basis of a type-examination certificate for the figures in the first period ; the period of validity shall accordingly be shown on the certificates of conformity concerned.

6. For every compressor built in conformity with the type certified by EEC type-examination, the manufacturer shall complete a certificate of conformity conforming to the model given in Annex IV to the framework Directive in the columns relating to the EEC type-examination certificate.

ANNEX I METHOD OF MEASURING AIRBORNE NOISE EMITTED BY COMPRESSORS

SCOPE

This measurement method is applicable to compressors. It specifies the test procedures for use in determining the sound power level of such equipment for the purpose of EEC type-examination and testing as to conformity.

These technical procedures shall comply with the requirements of Annex I to Directive 79/113/EEC.

All the sections in Annex I to Directive 79/113/EEC shall apply to compressors, subject to the following amendments:

4. CRITERIA TO BE USED FOR EXPRESSING RESULTS

4.1. The acoustic criterion for the environment of compressors is their sound power level.

6. MEASURING CONDITIONS

6.1. During testing, no tools shall be coupled to the compressor. At each measuring point, the noise level of release and escape of air from the external lines coupled to the air outlet valves of compressors shall be more than 10 dB lower than the noise level of the compressor.

6.2. Operation of the sound source during measurement.

6.2.1. Not applicable.

6.2.2. The compressor shall be brought to its steady-state temperature within the range specified by the manufacturer. It shall operate at its nominal speed and its nominal pressure.

The nominal speed and pressure are those appearing in the direction for use supplied to the purchaser.

In these operating conditions, the air flow shall be checked as laid down in International Standard ISO 1217, first edition, 1975.

6.3. Measuring site.

The compressor shall be installed on a reflecting plane of concrete or non-porous asphalt. Skid-mounted compressors shall be placed on supports 0,40 m high, unless otherwise required by the manufacturer's conditions of installation.

6.4.1. Measuring surface.

The measuring surface to be used for testing shall be a hemisphere. The centre of the hemisphere shall be the vertical projection onto the reflecting plane of the geometric centre of the compressor. The radius shall be: - 4 m, where the greatest dimension of the compressor to be tested is not more than 1,5 m,

- 10 m, where the greatest dimension of the compressor to be tested is more than 1,5 m but not more than 4 m,

- 16 m, where the greatest dimension of the compressor to be tested is more than 4 m.

Table I in Annex I to Directive 79/113/EEC gives the coordinates of the measuring points.

6.4.2.1. The x axis of the set of coordinates, in relation to which the positions of the measuring points are fixed, shall be parallel to the main axis of the compressor.

7. MEASUREMENTS

7.1.1. Only the background noise shall be taken into account for the purpose of corrections.

7.1.5. Presence of obstacles

A visual check in a circular zone with a radius of three times that of the measurement hemisphere and the centre of which coincides with the centre of that hemisphere is adequate to ensure that the provisions of the third subparagraph of section 6.3 of Annex I to Directive 79/113/EEC are complied with.

7.2. If the sound pressure levels at the measuring points are determined from readings taken by a sonometer, there shall be at least five such readings, taken at regular intervals.

8. USE OF RESULTS

8.2. Not applicable.

8.6.2. In view of 6.3, section 8.6.2 is not applicable and C = 0.
