26、rt 2-21: Particular Requirements For Drain Cleaners. It is the rst edition of CAN/CSA-C22.2 No. 60745-2-21 and the rst edition of UL 60745-2-21. This standard is an adoption of IEC 60745-2-21, rst edition. This Standard CAN/CSA-C22.2 No. 60745-2-21/UL 60745-2-21, rst edition, supersedes: a) the rst
27、edition of CAN/CSA-C22.2 No. 745-2-35/UL 745-2-35 published in 1995; and b) CAN/CSA-C22.2 No. 745-4-35/UL 745-4-35, published in 1995 (requirements for battery tools and battery packs are now incorporated into the requirements of CAN/CSA-C22.2 No. 60745-2-21, rst edition, and UL 60745-2-21, rst edit
28、ion). The standard number has been aligned to correspond with the equivalent IEC 60745-2-21 standard. This common standard was prepared by the Canadian Standards Association (CSA) and Underwriters Laboratories Inc. (UL). This standard was reviewed by the CSA Subcommittee on Safety of Hand-Held Motor
29、-Operated Electric Tools, under the jurisdiction of the CSA Technical Committee on Consumer and Commercial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been approved as a Nati
30、onal Standard of Canada by the Standards Council of Canada (SCC). This standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Note: Although the intended primary application of this Standard is stated in its scope, it is important to note tha
31、t it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose. Where reference is made to a specic number of samples to be tested, the specied number shall be considered a minimum quantity. Level of Harmonization This standard adopts the IEC text
32、with no national differences. This standard is published as an identical standard for CSA and UL. An identical standard is a standard that is exactly the same in technical content except for national differences resulting from conicts in codes and governmental regulations. Presentation is word for w
33、ord except for editorial changes. Interpretations The interpretation by the standards development organization of an identical or equivalent standard is based on the literal text to determine compliance with the standard in accordance with the procedural rules of the standards development organizati
34、on. If more than one literal interpretation has been identied, a revision is to be proposed as soon as possible to each of the standards development organizations to more accurately reect the intent.

38、ATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTERNATIONAL ELECTROTECHNICAL COMMISSION HAND-HELD MOTOR-OPERATED ELECTRIC TOOLS SAFETY PART 2-21: PARTICULAR REQUIREMENTS FOR DRAIN CLEANERS FOREWORD 1) The International Electrotechnical Commission (IEC) is
39、 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 elds. To this end and in addition to ot
40、her activities, IEC publishes International Standards, Technical Specications, Technical Reports, Publicly Available Specications (PAS) and Guides (hereafter referred to as IEC Publication(s) ). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subj
41、ect dealt with may participate in this preparatory work. International, governmental and nongovernmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions dete
42、rmined 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 interested IEC National Commi
43、ttees. 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 responsible for the way in which
44、 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 divergence between any IEC Publicati
45、on and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that
46、 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 committees and IEC National Committees for any personal injury, property damage or other damage of any natu
47、re 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. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced
48、 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 rights. IEC shall not be held responsible for identifying any or all such patent rights. This part o
49、f International Standard IEC 60745 has been prepared by subcommittee 61F: Safety of hand-held motor-operated electric tools, of IEC technical committee 61: Safety of household and similar electrical appliances This consolidated version of IEC 60745-2-21 consists of the rst edition (2003) documents 61F/483/FDIS and 61F/504/RVD and its amendment 1 (2008) documents 61F/739/FDIS and 61F/759/RVD.
