35、 Technical Committee CEN/TC 197, Pumps, the Secretariat of which is held by AFNOR.

This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative annex ZA, which is
37、an integral part of this standard.

39、00 B SI 0002-50 Introduction The noise emitted by a pump unit can be radiated by the casing of the pump, the driving system (e.g. motor, gear box, coupling), the piping system and all the connected structures. On site the perceived noise can be significantly increased by reverberation effects or by
40、the radiation of extraneous sources. Depending on the type of pump it may be useful to know: a) the noise of the pumping system (including piping); b) the noise of the pump unit, including the driver and the transmission elements but excluding the noise of the piping system; c) the noise emitted by
41、the pump alone, excluding the noise from the driver, transmission elements and the pipings; d) the noise emitted by each of those elements in respect to a given requirement or in view of an efficient sound proofing of the installation. This European Standard describes methods for the determination o
42、f the noise emitted by a pump unit (case b) or a pump alone (case c). Noise emission is expressed in terms of the sound power level of the machine and the emission sound pressure level at the relevant work station (see 6.2). This European Standard is intended to enable the manufacturer to: ? show th
43、e effectiveness of noise reduction; ? declare the noise emission levels. This European Standard is a type C standard as stated in EN 292. The machinery concerned and the extent to which noise is covered are indicated in the scope of this standard. When provisions of this type C standard are differen
44、t from those which are stated in A or B standards, the provisions of this type C standard take precedence. Licensed Copy: sheffieldun sheffieldun, na, Sat Oct 28 06:29:57 GMT+00:00 2006, Uncontrolled Copy, (c) BSI Page 5 EN 12639:2000 B SI 0002-50 1 Scope This European Standard specifies all the inf
45、ormation necessary to carry out efficiently and under standardized conditions the determination, declaration and verification of the airborne noise emission of liquid pumps or pump units (see 4.1). It specifies the noise measurement methods and the operating and mounting conditions that shall be use
46、d for the test. Noise emission characteristics include emission sound pressure levels at specified positions and the sound power level. The determination of these quantities is necessary for: ? declaring the noise emission values; ? purpose of noise control at source at the design stage. NOTEThe det
47、ermination of these quantities is also necessary for comparing the noise emitted by liquid pumps on the market. The use of this European Standard ensures the reproducibility of the determination of the airborne noise emission characteristics within specified limits determined by the grade of accurac
48、y of the basic airborne noise measurement method used. Noise measurement methods according to this European Standard are engineering methods (grade 2) and survey methods (grade 3). This European Standard does not deal with the characterization of the structure-borne sound and liquid-borne noise gene
49、rated by liquid pumps. This European Standard is intended to complement EN 809. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorpora
