20、TECHNICAL COMMISSION _ HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES TEST CODE FOR THE DETERMINATION OF AIRBORNE ACOUSTICAL NOISE Part 2-10: Particular requirements for electric cooking ranges, ovens, grills, microwave ovens and any combination of these FOREWORD 1) The International Electrotechnical C

21、ommission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end a

22、nd in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committ

23、ee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in acco

24、rdance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all in

25、terested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held respo

26、nsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergenc

27、e between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks

28、 of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts

29、and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publi

30、cation or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publi

40、0 IEC:2011 INTRODUCTION The measuring conditions specified in this Part 2-10 of IEC 60704 provide for sufficient accuracy in determining the noise emitted and comparing the results of measurements taken by different laboratories, whilst simulating as far as possible the practical use of electric coo

41、king ranges, ovens, grills, microwave ovens and any combination of these. It is recommended to consider the determination of noise levels as part of a comprehensive testing procedure covering many aspects of the properties and performance of household appliances. Compared to the first edition (2004)

42、 of this Part 2-10, the second edition doesnt contain the description of an appropriate test enclosure which has now been incorporated in Part 1. NOTE As stated in the Introduction to IEC 60704-1, this test code is concerned with airborne noise only. 60704-2-10 IEC:2011 5 HOUSEHOLD AND SIMILAR ELECT

43、RICAL APPLIANCES TEST CODE FOR THE DETERMINATION OF AIRBORNE ACOUSTICAL NOISE Part 2-10: Particular requirements for electric cooking ranges, ovens, grills, microwave ovens and any combination of these 1 Scope and object This clause of Part 1 is applicable except as follows: 1.1 Scope 1.1.1 General

44、Addition: These particular requirements apply to electric cooking ranges, ovens, grills, microwave ovens and any combination of these for household and similar use. NOTE 101 These particular requirements do not apply to hobs due to lack of standardised load (pans) representative of normal use and en

45、suring a good repeatability of tests. For these applications, the loading and operating conditions are under consideration. This standard does not apply to appliances or parts of appliances that use gas energy. 1.1.2 Types of noise Replacement: The methods specified in ISO 3743-1, ISO 3743-2 and ISO

46、 3744 can be used for measuring noise emitted by electric cooking ranges, ovens, grills, microwave ovens and any combination of these. 1.1.3 Size of the source Replacement: The method specified in ISO 3744 is applicable to noise sources of any size. When applying ISO 3743-1 and ISO 3743-2, care shou

47、ld be taken that the maximum size of the appliance under test fulfils the requirements specified in 1.3 of ISO 3743-1:1994 and ISO 3743-2:1994. 1.2 Object Addition: The methods described are specified for appliances without an operator present. Requirements for the declaration of noise emission valu

48、es are not within the scope of this standard. NOTE 101 For determining and verifying noise emission values declared in product specifications, see IEC 60704-3. 6 60704-2-10 IEC:2011 1.3 Measurement uncertainty Replacement: The estimated values of standard deviations of sound power levels, determined

49、 according to this standard, are as follows: Table 101 Standard deviations of sound power levels Standard deviation dB r(repeatability) R(reproducibility) 0,4 1,0 1.101 Standard deviation for declaration and verification For the purpose of determining and verifying declared noise emission values according to IEC 60704-3, the following values apply: Table 102 Standard deviations for declaration and
