Directive 2000/14/EC of the European Parliament and of the CouncilShow full title

Scope U.K.

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.

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

• 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 K_2A

  • 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.
