23、International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee
24、 has been established has the right to be represented on that committee. International organizations, 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 electrotechnic
25、al standardization.The procedures used to develop this document and those intended for its further maintenance 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
26、accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

The mac

31、s of the other standards, for machines that have been designed and built according to the provisions of this type C standard.

32、is International Standard provides technical information on the design of textile machinery 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-nois
33、e textile machinery. For this purpose, the significant sources of noise of the individual 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
34、 International Standard (e.g. elements for transportation of process material, elements 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.

38、n operating position higher than 70 dBNote 1 to entry: In this case, it is probable that 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 sourc

40、he following substantial requirements should be considered for conceiving and designing textile machinery.The machine shall be conceived and designed so as to reduce hazards from noise emissions to the attainable lowest load by taking into consideration the technical progress and the available means
41、 for noise control, primarily at the source.4.2 ProcedureIn order to achieve the substantial aims according to 4.1, the following procedure is recommended.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
42、 workstation, no further measures for noise control are required.Step 2: Identification of significant noise sourcesTo identify machine elements and physical processes dominating the noise emissions, the following methods might be useful:a) evaluation of revolutions and of the dominating frequencies
43、 of the radiated sound;b) comparative noise measurements with changing the parameters so as to draw conclusions with regard to significant noise sources;c) sound intensity measurements to be used for defining the loudest machine ranges;d) calculation of structure-borne noise (simulation).Step 3: Spe
44、cifying and taking noise control measuresNoise control measures should concentrate on significant noise sources to allow good prospect of success of the measures taken. Thus, a favourable relation between expenditure and benefit might be expected.The measures shall be taken in the following order:a)
45、 reduction of sound generation;b) reduction of sound propagation;c) provision of conditions for installation, maintenance, inspection, repair, spare 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 pr
46、otectors during operation of the machine.Step 4: Verification of the success of measures takenThe success of the measure shall be verified by noise 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
47、the noise control attained is not sufficient, the procedure is repeated beginning with step 2. The measures for noise control may be concluded, if 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
48、 technology of the machine type has been achieved or is below that level.2 ISO 2015 All rights reservedBS EN ISO 23771:2015ISO 23771:2015(E)NOTE The state-of-the-art technology represents the technical possibilities given at a certain time.
