30、ake precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard.4DIN EN ISO 23771:2015-06 EN ISO 23771:2015 (E) 1 ScopeThis International Standard provides technical information on the design of textile mac

31、hinery with reduced noise emissions. Textile machines with a significant noise hazard are defined in ISO 11111 (all parts).This International Standard supports the technical designer with the development of low-noise textile machinery. For this purpose, the significant sources of noise of the indivi

32、dual types of textile machines and suitable noise control measures are described.Elements needed for the operation of the textile machine, which are, however, not part of the textile machine, are not covered by this International Standard (e.g. elements for transportation of process material, elemen

33、ts for provision of media).2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

37、hat for the machine user under real production conditions (environmental correction, environment noise, operation of several machines) an emission value of 80 dB(A) is attained or exceeded.3.2significant noise sourcenoise source which dominates the noise emission generated by a machine5DIN EN ISO 23

38、771:2015-06EN ISO 23771:2015 (E)4 Concept for noise emission control4.1 Substantial requirementsFor reduction of noise emissions from textile machines, the following substantial requirements should be considered for conceiving and designing textile machinery.The machine shall be conceived and design

39、ed so as to reduce hazards from noise emissions to the attainable lowest load by taking into consideration the technical progress and the available means for noise control, primarily at the source.4.2 ProcedureIn order to achieve the substantial aims according to 4.1, the following procedure is reco

40、mmended.Step 1: Detection of noise emission by measurement according to ISO 9902 (all parts)With an emission value of less than or equal to 70 dB(A) at a workstation, no further measures for noise control are required.Step 2: Identification of significant noise sourcesTo identify machine elements an

41、d physical processes dominating the noise emissions, the following methods might be useful:a) evaluation of revolutions and of the dominating frequencies of the radiated sound;b) comparative noise measurements with changing the parameters so as to draw conclusions with regard to significant noise so

42、urces;c) sound intensity measurements to be used for defining the loudest machine ranges;d) calculation of structure-borne noise (simulation).Step 3: Specifying and taking noise control measuresNoise control measures should concentrate on significant noise sources to allow good prospect of success o

43、f the measures taken. Thus, a favourable relation between expenditure and benefit might be expected.The measures shall be taken in the following order:a) reduction of sound generation;b) reduction of sound propagation;c) provision of conditions for installation, maintenance, inspection, repair, spar

44、e part specification, and quality of the used raw materials to be given for continuous low-noise operation of the machine;d) necessity to wear hearing protectors during operation of the machine.Step 4: Verification of the success of measures takenThe success of the measure shall be verified by noise

45、 measurements according to ISO 9902 (all parts). For these measurements, the machine should be operating in a mode specified by ISO 9902 (all parts). If the noise control attained is not sufficient, the procedure is repeated beginning with step 2. The measures for noise control may be concluded, if

46、the A-weighted emission sound pressure level at a workstation is less than or equal to 70 dB or the standard attainable according to the state-of-the-art technology of the machine type has been achieved or is below that level.6DIN EN ISO 23771:2015-06 EN ISO 23771:2015 (E) NOTE The state-of-the-art

47、technology represents the technical possibilities given at a certain time. The state-of-the-art technology also includes its economic feasibility.Step 5: DocumentationThe results of the working steps 1 to 4 shall be recorded in the technical documentation.The information for the machine user, which

48、is obtained during performing working steps 1 to 4, should be included in the instruction handbook5 Textile machinery with significant noise hazard5.1 GeneralTextile machinery with significant noise hazard is defined in ISO 11111 (all parts) and listed in detail in 5.2.
