11、n publication. This Standard was prepared by the Australian members of the Joint Standards Australia/Standards New Zealand Committee EL-009. After consultation with stakeholders in both countries, Standards Australia and Standards New Zealand decided to develop this Standard as an Australian Standar

This Standard is identical with, and has been reproduced from IEC 60034-9, Ed. 4.1 (2007), Rotating electr

25、ODUCTION Acoustic quantities can be expressed in sound pressure terms or sound power terms. The use of a sound power level, which can be specified independently of the measurement surface and environmental conditions, avoids the complications associated with sound pressure levels, which require addi
26、tional data to be specified. Sound power levels provide a measure of radiated energy and have advantages in acoustic analysis and design. vi NOTES The Standard is downloaded from Standard Sharing www.standards.org.au Standards Australia 1 STANDARDS AUSTRALIA AustralianStandard Rotating electrical m
27、achines Part 9: Noise limits 1 Scope This part of IEC 60034: specifies test methods for the determination of sound power level of rotating electrical machines; specifies maximum A-weighted sound power levels for factory acceptance testing of network-supplied, rotating electrical machines in accordan
28、ce with lEC 60034-1, having methods of cooling according to lEC 60034-6 and degrees of protection according to lEC 60034-5, and having the following characteristics: standard design, either a.c. or d.c., without additional special electrical, mechanical, or acoustical modifications intended to reduc
29、e the sound power level; rated output from 1 kW (or kVA) up to and including 5 500 kW (or kVA); rated speed not greater than 3 750 min1. provides guidance for the determination of noise levels for a.c. cage induction motors supplied by converters. Excluded are a.c. motors supplied by converters. For
30、 these conditions see IEC 60034-17 for guidance. The object of this standard is to determine maximum A-weighted sound power levels, LWA in decibels, dB, for airborne noise emitted by rotating electrical machines of standard design, as a function of power, speed and load, and to specify the method of
31、 measurement and the test conditions appropriate for the determination of the sound power level of the machines to provide a standardized evaluation of machine noise up to the maximum specified sound power levels. This standard does not provide correction for the existence of tonal characteristics.
32、Sound pressure levels at a distance from the machine may be required in some applications, such as hearing protection programs. Information is provided on such a procedure in Clause 8 based on a standardized test environment. NOTE 1 This standard recognizes the economic reason for the availability o
33、f standard noise-level machines for use in non-critical areas or for use with supplementary means of noise attenuation. NOTE 2 Where sound power levels lower than those specified in Tables 1 or 2 are required, these should be agreed between the manufacturer and the purchaser, as special electrical,
34、mechanical, or acoustical design may involve additional measures. 2 Normative references The following referenced documents are indispensable for the application of this document.

45、 document, the terms and definitions given in the standards listed in the normative references together with the following apply. 3.1 sound power level LW ten times the logarithm to the base 10 of the ratio of the sound power radiated by the source under test to the reference sound power Wo = 1 pW (
46、1012 W) expressed in decibels 3.2 sound pressure level Lp ten times the logarithm to the base 10 of the ratio of the square of the sound pressure to the square of the reference sound pressure Po = 20 Pa (2 105 Pa) expressed in decibels 4 Methods of measurement 4.1 Sound pressure level measurements a
47、nd calculation of sound power level produced by the machine shall be made in accordance with ISO 3744, unless one of the alternative methods specified in 4.3 or 4.4 below applies. NOTE It is recommended that the hemispherical method be used for machines with shaft height up to 180 mm and the paralle
48、lepiped method used for machines larger than 355 mm. Either method may be used for intermediate shaft heights. 4.2 The maximum sound power levels specified in Tables 1 and 2 or adjusted by Table 3, relate to measurements made in accordance with 4.1. 4.3 When appropriate, one of the methods of precis
49、ion or engineering grade accuracy, such as the methods of ISO 3741, ISO 3743-1, ISO 3743-2, ISO 3745, ISO 9614-1 or ISO 9614-2, may be used to determine sound power levels. 4.4 The simpler but less accurate method specified in ISO 3746 or ISO 3747 may be used, especially when the environmental conditions required by ISO 3744 cannot be satisfied (for example, for large machines).
