The work of preparing International Standards is normally carried out through ISO tech
19、nical 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, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
20、 with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to
21、the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 1680 was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 1, Noise. This first edition of ISO 1680 cancels an
22、d replaces ISO 1680-1:1986 and ISO 1680-2:1986, which have been combined and technically revised. Annexes A and B of this International Standard are for information only.

23、91:0861 OSI v Introduction This International Standard is a noise test code giving methods for determining the airborne sound radiation of rotating electrical machines operating under steady-state conditions. To characterize the airborne sound radiation, procedures are given to determine sound power
24、 levels and additionally emission sound pressure levels, if required. Furthermore, requirements are given for the declaration and verification of noise emission values. Basic standards giving methods for determining sound power levels are as follows: a) using sound pressure: grade 1 (precision): ISO
25、 3741 and ISO 3745; grade 2 (engineering): ISO 3743-1, ISO 3743-2, ISO 3744, ISO 3747; grade 3 (survey): ISO 3746; b) using sound intensity: all grades: ISO 9614-1; grades 2 and 3: ISO 9614-2. The emission sound pressure level is determined on the basis of ISO 11203. Declaration and verification of
26、noise emission values follow ISO 4871. This International Standard has been drafted in accordance with ISO 12001.

28、ly 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 specifies the operating and mounting conditions that shall be used for the test. No
29、ise 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 the noise emitted, and for the purposes of noise control. The use of this I
30、nternational 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 used. Noise measurement methods allowed by this International Standard a
31、re laboratory 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 any length, width or height. 2 Normative references The following norm
32、ative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard
