27、IEC 2014 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES TEST CODE FOR THE DETERMINATION OF AIRBORNE ACOUSTICAL NOISE Part 2-1: Particular requirements for vacuum cleaners FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organiz
28、ation 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 and in addition to other activities, IE
29、C 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 Committee interested in the subject dealt wit
30、h 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 accordance with conditions determined by a
31、greement 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 interested IEC National Committees. 3) I
32、EC 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 responsible for the way in which they are u
33、sed 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 divergence between any IEC Publication and the
34、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 of conformity. IEC is not responsible
35、 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 and members of its technical committee
36、s 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 Publication or any other IEC Publications.
37、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 Publication may be the subject of patent ri
38、ghts. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60704-2-1 has been prepared by subcommittee 59F: Floor treatment appliances, of IEC technical committee 59: Performance of household and similar electrical appliances. This third edition
39、 cancels and replaces the second edition published in 2000. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) introduction of a measuring method on hard floors; b) inclusion of values for measurem
40、ent uncertainty; c) inclusion of values for standard deviation for declaration and verification; 4 IEC 60704-2-1:2014 IEC 2014 d) update of the definition of the standard test carpet. The text of this standard is based on the following documents: FDIS Report on voting 59F/255/FDIS 59F/259/RVD Full i
41、nformation on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This Part 2-1 is intended to be used in conjunction with IEC 60704-1:2010, Household and similar electrical appliances Test code for the determination of airborne acoustical
42、noise Part 1: General requirements. NOTE When “Part 1” is mentioned in this standard, it refers to IEC 60704-1. The relevant text of Part 1 as amended by this standard establishes the test code for vacuum cleaners. This Part 2-1 supplements or modifies the corresponding clauses in IEC 60704-1. When
43、a particular subclause of Part 1 is not mentioned in this Part 2-1, that subclause is applicable as far as reasonable. Where this standard states “addition“, “modification“ or “replacement“, the relevant requirements, test specifications or explanatory matter in Part 1 should be adapted accordingly.
44、 Subclauses, tables and figures that are additional to those in Part 1 are numbered starting from 101. Additional annexes are lettered AA, BB, etc. Unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including those in a replaced clause or subclause.
45、A list of all the parts in the IEC 60704 series, published under the general title Household and similar electrical appliances Test code for the determination of airborne acoustical noise, can be found on the IEC website. This publication has been drafted in accordance with the ISO/IEC Directives, P
46、art 2. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by
47、 a revised edition, or amended. IEC 60704-2-1:2014 IEC 2014 5 INTRODUCTION The measuring conditions specified in this part 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
48、 as possible the practical use of vacuum cleaners. It is recommended to consider the determination of noise levels as part of a comprehensive testing procedure covering many aspects of properties and performance of household vacuum cleaners. NOTE As stated in the introduction to IEC 60704-1, this te
49、st code is concerned with airborne noise only. 6 IEC 60704-2-1:2014 IEC 2014 HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES TEST CODE FOR THE DETERMINATION OF AIRBORNE ACOUSTICAL NOISE Part 2-1: Particular requirements for vacuum cleaners 1 Scope and object This clause of Part 1 is applicable except as follows: 1.1 Scope General 1.1.1 Replacement: These particular requirements apply to electrical vacuum cl
