20、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 has been established has the right to be represented on that committee. International organizations, govern

21、mental 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 maintenan

22、ce 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, www.iso.org/directives.Attention is d

26、ernational Standard specifies all the information necessary to carry out efficiently and under standardized conditions the determination, declaration, and verification of the noise emission characteristics of rotating electrical machines. It specifies noise measurement methods that can be used, and

27、specifies the operating and mounting conditions required for the test.Noise emission characteristics include the sound power level and emission sound pressure level. The determination of these quantities is necessary: for comparing the noise emitted by machines; to enable manufacturers to declare th

28、e noise emitted; and for the purposes of noise control.The use of this International Standard as a noise test code ensures the reproducibility of the determination of the noise emission characteristics within specified limits determined by the grade of accuracy of the basic noise measurement method

29、used. Noise measurement methods allowed by this International Standard are precision methods (grade 1), engineering methods (grade 2) and survey methods (grade 3). Methods of engineering grade (grade 2) are to be preferred.This International Standard is applicable to rotating electrical machines of

30、any length, width or height.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
