18、CAL COMMISSION _ ELECTRIC MOTOR-OPERATED HAND-HELD TOOLS, TRANSPORTABLE TOOLS AND LAWN AND GARDEN MACHINERY SAFETY Part 3-10: Particular requirements for transportable cut-off machines FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization com

19、prising 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, IEC publishes International Sta

20、ndards, 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 with may participate in this pre

21、paratory 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 agreement between the two orga

22、nizations. 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) IEC Publications have the form

23、 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 used or for any misinterpretat

24、ion 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 corresponding national or reg

25、ional 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 for any services carried out

26、 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 committees and IEC National Committees

27、 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. 8) Attention is drawn to the

28、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 rights. IEC shall not be held r

29、esponsible for identifying any or all such patent rights. International Standard IEC 62841-3-10 has been prepared by IEC technical committee 116: Safety of motor-operated electric tools. The text of this standard is based on the following documents: FDIS Report on voting 116/240/FDIS 116/253/RVD Ful

30、l information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. IEC 62841-3-10:2015 IEC 2015 5 This Part 3-10 is to be used in conjunction with the fi

31、rst edition of IEC 62841-1 (2014). This Part 3-10 supplements or modifies the corresponding clauses in IEC 62841-1, so as to convert it into the IEC Standard: Particular requirements for transportable cut-off machines. Where a particular subclause of Part 1 is not mentioned in this Part 3-10, that s

32、ubclause applies as far as relevant. Where this standard states “addition”, “modification” or “replacement”, the relevant text in Part 1 is to be adapted accordingly. The following print types are used: requirements: in roman type; test specifications: in italic type; notes: in small roman type. Wor

33、ds in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the associated noun are also in bold. Subclauses, notes and figures which are additional to those in Part 1 are numbered starting from 101. A list of all parts of the IEC 62841 series, under th

34、e general title: Electric motor-operated hand-held tools, transportable tools and lawn and garden machinery Safety, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http

35、:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. NOTE The attention of National Committees is drawn to th

36、e fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the rec

37、ommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 36 months from the date of publication. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be use

38、ful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 6 IEC 62841-3-10:2015 IEC 2015 ELECTRIC MOTOR-OPERATED HAND-HELD TOOLS, TRANSPORTABLE TOOLS AND LAWN AND GARDEN MACHINERY SAFETY Part 3-10: Particular requirements for transportable
