It also incorporates the Technical Corrigendum ISO 11200:1995/Corr.1:1997.iv ISO 2014 All rights reservedBS EN ISO 11200:2014ISO 11200:2014(E)Introduction0.1 For many users of machinery and equipment, the control of noise

33、 is a major issue which requires effective exchange of acoustical information among the several parties concerned. These include the manufacturer, installer and user of the machinery or equipment. This acoustical information is obtained from measurements. The main flow of information goes from the m

34、anufacturer to the user.These measurements are useful only if the conditions under which they are carried out are specified, if they yield defined acoustical quantities, and if they are carried out using standardized instruments.Two quantities which complement one another can be used to describe the

35、 sound emission of machinery or equipment: the sound power level and the emission sound pressure level at a specified position. The International Standards which describe the basic methods of determining the sound power level are ISO 3740,2ISO 3741, ISO 3743 (all parts), ISO 3744, ISO 3745, ISO 3746

36、 and ISO 3747 (determination from sound pressure level measurements), and ISO 9614-1, ISO 9614-2 and ISO 9614-3 (determination from sound intensity measurements). This International Standard introduces a group of five International Standards describing various methods for determining emission sound

37、pressure levels of machinery and equipment taking into account possible situations for the source under test (mobile machine, fixed machine, various test rooms, various instrumentations, different kinds of work stations, etc.).It is not the intention of this group of International Standards to descr

38、ibe procedures for measuring the occupational noise exposure of workers; for occupational noise exposure, see ISO 9612.40.2 Emission sound pressure levels in conjunction with sound power levels are used for declaration of the noise emitted under the defined conditions, verification of declared value

39、s, comparison of the noise emitted by machinery of various types and sizes, comparison with limits specified in a purchasing contract or a regulation, engineering work to reduce the noise emission of machinery, and prediction of noise exposure at the specified positions.Included in this group of Int

40、ernational Standards are three, which describe procedures for measuring emission sound pressure levels directly, in different test environments (ISO 11201, ISO 11202 and ISO 11204), a fourth (ISO 11203), which gives procedures for determining emission sound pressure levels from the sound power level

41、 and a fifth (ISO 11205), which gives a procedure for determining the emission sound pressure level from measured values of the sound intensity level.0.3 In general, these sound pressure levels are different from those which occur if the machinery or equipment operates in its installed surroundings,

42、 where the environment influences the sound pressure level at work stations or other specified positions. The selection of standards for the determination of the sound power level can, for practical reasons, have consequences on the selection of standards for the determination of the emission sound

43、pressure level. It is preferable to make the choice of standards concurrently with respect to the two noise emission quantities.0.4 Standards in the ISO 11201, ISO 11202, ISO 11203, ISO 11204 and ISO 11205 group are often used in practice through their reference in standardized noise test codes (see

44、 3.25). If a particular noise test code exists for a family of machinery, it is intended that it be used. For drafting a noise test code, it is recommended to be familiar with ISO 12001.60.5 The reasons for revising the ISO 11201, ISO 11202, ISO 11203, ISO 11204 and ISO 11205 group were manifold: th

45、e need arose to introduce a grade 1 method into the group in order to enhance the similarity with the ISO 3741, ISO 3743 (all parts), ISO 3744, ISO 3745, ISO 3746 and ISO 3747 group of International Standards on the determination of sound power level; feedback from experience with the use of the gro

46、up showed that the ISO 11202 method gave more precise results than initially thought, hence the introduction into ISO 11202 of the possibility to get grade 2 results; as source directivity plays a key role with regard to the emission sound pressure level, pragmatism led to introduce this parameter i

47、nto the ISO 11202 and ISO 11204 methods; ISO 2014 All rights reserved vBS EN ISO 11200:2014ISO 11200:2014(E) as measurement uncertainty was becoming a more and more central issue, the need arose to address the issue again in the light of the experience gained with the use of ISO/IEC GUIDE 98-3.No re

48、search was carried out in order to revise the ISO 11201, ISO 11202, ISO 11203, ISO 11204 and ISO 11205 group.
