23、orldwide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to oth

24、er activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IE

25、C also participate in this preparation. The IEC collaborates closely with the InternationalOrganization for Standardization (ISO) in accordance with conditions determined by agreement between thetwo organizations.2) The formal decisions or agreements of the IEC on technical matters express, as nearl

26、y as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3) The documents produced have the form of recommendations for international use and are published in the formof standards, technical

27、specifications, technical reports or guides and they are accepted by the NationalCommittees in that sense.4) In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regiona

28、l standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one

29、of its standards.6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.This part of International Standard IEC 60335 has been prepared b

30、y IEC subcommittee 61F:Safety of hand-held motor-operated electric tools, of IEC technical committee 61: Safety ofhousehold and similar electrical appliances.This second edition cancels and replaces the first edition published in 2000. It constitutes atechnical revision.The text of this standard is

31、based on the following documents:FDIS Report on voting61F/453/FDIS 61F/474/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and itsamend

32、ments. It was established on the basis of the fourth edition (2001) of that standard.NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60335-1.This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as toconvert that publication into the IEC standard: Safe

33、ty requirements for pedestrian-controlledmains-operated electric lawn scarifiers and aerators.60335-2-92 IEC:2002(E) 5 When a particular subclause of Part 1 is not mentioned in this part 2, that subclause appliesas far as is reasonable. When this standard states “addition”, “modification” or “replac

34、ement”,the relevant text in Part 1 is to be adapted accordingly.NOTE 2 The following numbering system is used: subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1; unless notes are in a new subclause or involve notes in Part 1, they are numbered start

35、ing from 101, includingthose in a replaced clause or subclause; additional annexes are lettered AA, BB, etc.NOTE 3 The following print types are used: requirements proper: in roman type; test specifications: in italic type; notes: in small roman type;Words in bold in the text are defined in Clause 3

36、. When a definition concerns an adjective, the adjective and theassociated noun are also in bold.The committee has decided that the contents of this publication will remain unchanged until2004. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended.A

37、bilingual version of this publication may be issued at a later date. 6 60335-2-92 IEC:2002(E)INTRODUCTIONIt has been assumed in the drafting of this international standard that the execution of itsprovisions is entrusted to appropriately qualified and experienced persons.This standard recognizes the

38、 internationally accepted level of protection against hazards suchas electrical, mechanical, thermal, fire and radiation of appliances when operated as innormal use taking into account the manufacturers instructions. It also covers abnormalsituations that can be expected in practice.This standard ta

39、kes into account the requirements of IEC 60364 as far as possible so thatthere is compatibility with the wiring rules when the appliance is connected to the supplymains. However, national wiring rules may differ.If an appliance within the scope of this standard also incorporates functions that are c

40、overedby another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, asfar as is reasonable. If applicable, the influence of one function on the other is taken intoaccount.This standard is a product family standard dealing with the safety of appliances and takesprecedenc

41、e over horizontal and generic standards covering the same subject.An appliance that complies with the text of this standard will not necessarily be considered tocomply with the safety principles of the standard if, when examined and tested, it is found tohave other features that impair the level of

42、safety covered by these requirements.An appliance employing materials or having forms of construction differing from those detailedin the requirements of this standard may be examined and tested according to the intent ofthe requirements and, if found to be substantially equivalent, may be considere

43、d to complywith the standard.60335-2-92 IEC:2002(E) 7 HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES SAFETY Part 2-92: Particular requirements for pedestrian-controlledmains-operated lawn scarifiers and aerators1 ScopeThis clause of Part 1 is replaced by the following.This International Standard deals

44、with the safety of pedestrian-controlled mains-operatedelectrical lawn scarifiers and aerators with rotating cutters for regenerating lawns by, forinstance, combing out grass thatch and moss, or by cutting vertically into the lawn face.These scarifiers are designed primarily for use at and around th

45、e home or for similarpurposes, their rated voltage being not more than 250 V single phase.This standard does not, in general, take into account: the use of appliances by young children or infirm persons without supervision; playing with the appliance by young children.NOTE 101 Attention is drawn to

46、the fact that in many countries additional requirements are specified by the national authorities responsible for the protectionof labour.NOTE 102 This standard does not apply to lawnmowers (IEC 60335-2-77); lawn trimmers and lawn edge trimmers (IEC 60335-2-91); lawn edgers, flail mowers, sickle-bar

47、 mowers or agricultural mowers.2 Normative referencesThis clause of Part 1 is applicable except as follows.Addition:ISO 2758:2001, Paper Determination of bursting strengthISO 3411:1995, Earth-moving machinery Human physical dimensions of operators andminimum operator space envelopeISO 3767-1:1998, T
