DIRECTIVE 2000/14/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL

of 8 May 2000

on the approximation of the laws of the Member States relating to the noise emission in the environment by equipment for use outdoors







Article 1

Objectives

The aim of this Directive is to harmonise the laws of the Member States relating to noise emission standards, conformity assessment procedures, marking, technical documentation and collection of data concerning the noise emission in the environment of equipment for use outdoors. It will contribute to the smooth functioning of the internal market, while protecting human health and well-being.

Article 2

Scope

1. This Directive applies to equipment for use outdoors listed in Articles 12 and 13 and defined in Annex I. This Directive only covers equipment that is placed on the market or put into service as an entire unit suitable for the intended use. Non-powered attachments that are separately placed on the market or put into service shall be excluded, except for hand-held concrete-breakers and picks and for hydraulic hammers.

2. The following shall be excluded from the scope of this Directive:

— all equipment primarily intended for the transport of goods or persons by road or rail or by air or on waterways,

— equipment specially designed and constructed for military and police purposes and for emergency services.

Article 3

Definitions

For the purpose of this Directive the following definitions shall apply:

(a) ‘equipment for use outdoors’ means all machinery defined in Article 1(2) of Directive 98/37/EC of the European Parliament and of the Council of 22 June 1998 on the approximation of the laws of the Member States relating to machinery ( 1 ) which is either self-propelled or can be moved and which, irrespective of the driving element(s), is intended to be used, according to its type, in the open air and which contributes to environmental noise exposure. The use of equipment in an ambience where the transmission of sound is not or not significantly affected (for instance under tents, under roofs for protection against rain or in the shell of houses) is regarded as use in the open air. It also means non-powered equipment for industrial or environmental applications which is intended, according to its type, to be used outdoors and which contributes to environmental noise exposure. All these types of equipment are hereinafter referred to as ‘equipment’;

(b) ‘conformity assessment procedures’ means the procedures laid down in Annexes V to VIII, based on Decision 93/465/EEC;

(c) ‘marking’ means the visibly, legibly and indelibly affixing on the equipment of the CE marking defined in Decision 93/465/EEC accompanied by the indication of the guaranteed sound power level;

(d) ‘sound power level L WA’ means the A-weighted sound power in dB in relation to 1 pW as defined in EN ISO 3744:1995 and EN ISO 3746:1995;

(e) ‘measured sound power level’ means a sound power level as determined from measurements as laid down in Annex III; measured values may be determined either from a single machine representative for the type of equipment or from the average of a number of machines;

(f) ‘guaranteed sound power level’ means a sound power level determined in accordance with the requirements laid down in Annex III which includes the uncertainties due to production variation and measurement procedures and where the manufacturer, or his authorised representative established in the Community, confirms that according to the technical instruments applied and referred to in the technical documentation it is not exceeded.

Article 4

Placing on the market

This Annex lays down the methods of measurement of airborne noise that shall be used for the determination of the sound power levels of equipment covered by this Directive with a view to the conformity assessment procedures of this Directive.

Part A of this Annex for each type of equipment referred to in Article 2(1) lays down

— basic noise emission standards

— general supplements to these basic noise emission standards

for measuring the sound pressure level on a measurement surface enveloping the source and for calculating the sound power level produced by the source.

— a recommended basic noise emission standard including — — a reference to the basic noise emission standard chosen from Part A — the test area — the value of the constant K2A — the shape of the measurement surface — the number and position of microphones to be used

— operating conditions including — — the reference to a standard, if any — requirements relating to mounting of the equipment — a method to calculate the resulting sound power levels in the event that several tests with different operating conditions are to be used

— further information.

When testing specific types of equipment, the manufacturer or his authorised representative in the Community may in general choose one of the basic noise emission standards of Part A and apply the operating conditions of Part B for this specific type of equipment. In the event of a dispute, however, the recommended basic noise emission standard laid down in Part B has to be used together with the operating conditions of Part B.









PART A

BASIC NOISE EMISSION STANDARD

For the determination of the sound power level of equipment for use outdoors as defined by Article 2(1) the basic noise emission standards

EN ISO 3744:1995

EN ISO 3746:1995

may generally be used subject to the following general supplements:

1. Measurement uncertainty

Measurement uncertainties are not taken into account in the framework of conformity assessment procedures in the design phase.

2. Operation of source during test

2.1. Fan speed

If the engine of the equipment or its hydraulic system is fitted with (a) fans(s) it (they) must operate during the test. The fan speed is, in accordance with one of the following conditions, stated and set by the manufacturer of the equipment and must appear in the test report, this speed being used in further measurements.

(a) Fan drive directly connected to the engine

If the fan drive is directly connected to the engine and/or hydraulic equipment (e.g. by belt drive) it must operate during the test.

(b) Fan drive with several distinct speeds

If the fan can work at several distinct speeds the test shall be carried out either

— at its maximum working speed, or

— in a first test with the fan set at zero speed and in a second test the fan set at maximum speed. The resulting sound pressure level L pA shall then be calculated by combining both test results using the following equation: —

— where: — L pA,0 % is the sound pressure level determined with the fan set at zero speed — L pA,100 % is the sound pressure level determined with the fan set at maximum speed.

(c) Fan drive with continuous variable speed

If the fan can work at continuous variable speed, the test shall be carried out either according to 2.1(b) or with the fan speed set by the manufacturer at no less than 70 % of the maximum speed.

2.2. Test of powered equipment free of load

For these measurements, the engine and hydraulic system of the equipment must be warmed up in accordance with the instructions, and safety requirements must be observed.

The test is carried out with the equipment in a stationary position without operating the working equipment or travelling mechanism. For the purpose of the test, the engine will idle at no less than the rated speed corresponding to the net power ( *1 ).

If the machine is powered by a generator or from the mains, the frequency of the supply current, specified for the motor by the manufacturer, shall be stable at ± 1 Hz if the machine is equipped with an induction motor, and the supply voltage at ± 1 % of the rated voltage if the machine is equipped with a commutator motor. The supply voltage is measured at the plug of a non-detachable cable or cord, or at the inlet of the machine if a detachable cable is provided. The waveform of the current supplied from the generator shall be similar to that obtained from the mains.

If the machine is powered by battery, the battery shall be fully charged.

The speed used and the corresponding net power are stated by the manufacturer of the equipment and must appear in the test report.

If the equipment is fitted with several engines, they must work simultaneously during the tests. If this is not possible, each possible combination of engine(s) is to be tested.

2.3. Test of powered equipment under load

For these measurements, the engine (driving device) and hydraulic system of the equipment must be warmed up in accordance with the instructions, and safety requirements must be observed. No signalling device such as a warning horn or reversing alarm is to be operated during the test.

The speed or velocity of the equipment during the test must be recorded and appear in the test report.

If the equipment is fitted with several engines and/or aggregates they must work simultaneously during the tests. If this is not possible, each possible combination of engine(s) and/or aggregates is to be tested.

For each type of equipment that is to be tested under load, specific operating conditions must be laid down which shall, in principle, produce effects and stresses similar to those encountered under actual working conditions.

2.4. Test of hand-operated equipment

Conventional operating conditions for each type of hand-operated equipment shall be laid down that produce effects and stresses similar to those undergone under actual working conditions.

3. Calculation of surface sound pressure level

The surface sound pressure level shall be determined at least three times. If at least two of the determined values do not differ by more than 1 dB, further measurements will not be necessary; otherwise the measurements shall be continued until two values differing by no more than 1 dB are obtained. The A-weighted surface sound pressure level to be used for calculating the sound power level is the arithmetic mean of the two highest values that do not differ by more than 1 dB.

4. Information to be reported

The A-weighted sound power level of the source under test shall be reported to the nearest whole number (less than 0,5 use the lower number; greater than or equal to 0,5 use the higher number).

The report shall contain the technical data necessary to identify the source under test as well as the noise test code and the acoustical data.
