Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations,

36、 governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further ma

37、intenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). A

41、 edition (ISO 20361:2007), which has been technically revised.iv ISO 2015 All rights reservedBS EN ISO 20361:2015ISO 20361:2015(E)IntroductionThe 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 th

42、e connected structures.On site, the perceived noise can be significantly increased by reverberation effects or by the radiation of extraneous sources.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 un

43、it, including the driver and the transmission elements but excluding the noise of the piping system;c) the noise emitted by the pump alone, excluding 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 i

44、n view of an efficient sound proofing of the installation.This International Standard describes methods for the determination of 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 press

45、ure level at the relevant work station (see 6.2).This International Standard is intended to enable the manufacturer to show the effectiveness of noise 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 provi

46、sions 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.The machinery concerned and the extent to which noise is covered are indicated in the scope of this International Standard.

48、erification 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 pressure levels at specified positions and th

49、e 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 emitted 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.
