Representatives of manufacturers and users of pumps, and of the employers liability insurance associations contributed to this standard. This standard contains specifications giving detail to the essential requirements set out in Annex I
7、of the “Machinery Directive”, Directive 2006/42/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of that directive. Once this standard is cited in the Offi
8、cial Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The International Standards referred to in Clause 2 and the Bibliography, and
9、 which have been taken over as European Standards have been published as the corresponding DIN EN ISO Standards with the same number. Where the International Standards and documents referred to are not also DIN ISO Standards with the same number, there are no national standards available. Amendments
10、 This standard differs from DIN EN ISO 20361:2010-10 as follows: a) the Annexes referring to the old EU Directive 98/37/EC and to European publications have been deleted; b) the standard has been editorially revised.

38、oise 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 the radiation of extraneous sourc
39、es.Depending on the type of pump it can be useful to know the following: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 the pump alone, excludi
40、ng the noise from the driver, transmission elements, and the piping;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 International Standard describes methods for the determination of the noise emitted
41、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 International Standard is intended to enable the manufacturer to show the effectiveness of no
42、ise reduction, and declare the noise emission levels.This International Standard is a type C standard as stated in ISO 12100-1 and ISO 12100-2.When provisions of this type C standard are different from those which are stated in A or B standards, the provisions of this type C standard take precedence
43、.The machinery concerned and the extent to which noise is covered are indicated in the scope of this International Standard.DIN EN ISO 20361:2016-05 EN ISO 20361:2015 (E)6 1 ScopeThis International Standard specifies all the information necessary to carry out efficiently and under standardized condi
44、tions 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 used for the test.Noise emission characteristics include emission sound pr
45、essure levels at specified positions and the sound power level. The determination of these quantities is necessary for declaring the noise emission values, and purpose of noise control at source at the design stage.The determination of these quantities is also necessary for comparing the noise emitt
46、ed by liquid pumps on the market.The use of this International Standard ensures the reproducibility of the determination of the airborne noise-emission characteristics within specified limits determined by the grade of accuracy of the basic airborne noise measurement method used. Noise measurement m
47、ethods according to this International Standard are engineering methods (grade 2) and survey methods (grade 3).This International Standard does not deal with the characterization of the structure-borne sound and liquid-borne noise generated by liquid pumps.NOTE This International Standard is intende
