19、hdrawn (dow) 2008-09-01 This standard has to be used in conjunction with EN 60335-1, Safety of household and similar electrical appliances - Part 1: General requirements, and EN 836, Garden equipment - Powered lawnmowers - Safety. This Part 2 supplements or modifies the corresponding clauses of EN 6
20、0335-1, so as to convert it into the European Standard: Household and similar electrical appliances - Safety - Particular requirements for pedestrian-controlled mains-operated lawn-mowers. When a particular subclause of Part 1 is not mentioned in this Part 2, that subclause applies as far as is reas
21、onable. When this standard states “addition”, “modification” or “replacement”, the relevant text of Part 1 is to be adapted accordingly. This European Standard has been prepared under a mandate given to CEN and CENELEC by the European Commission and the European Free Trade Association and supports t
22、he essential health and safety requirements of the Machinery Directive. See Annex ZZ. Other harmonised standards referred to this European Standard are listed in Annex ZC of Part 1 and this part. The annex lists the valid edition of those documents at the time of issue of this EN. All references are
23、 however to be understood as references to the latest edition. NOTE 1 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 startin

36、EC annexes and ISO 5395.54 5 EN 60335-2-77:2006 INTRODUCTION It has been assumed in the drafting of this international standard that the execution of its provisions is entrusted to appropriately qualified and experienced persons. This standard recognizes the internationally accepted level of protect
37、ion against hazards such as electrical, mechanical, thermal, fire and radiation of appliances when operated as in normal use taking into account the manufacturers instructions. It also covers abnormal situations that can be expected in practice. This standard takes into account the requirements of I
38、EC 60364 as far as possible so that there is compatibility with the wiring rules when the appliance is connected to the supply mains. However, national wiring rules may differ. If an appliance within the scope of this standard also incorporates functions that are covered by another part 2 of IEC 603
39、35, the relevant part 2 is applied to each function separately, as far as is reasonable. If applicable, the influence of one function on the other is taken into account. This standard is a product family standard dealing with the safety of appliances and takes precedence over horizontal and generic
40、standards covering the same subject. An appliance that complies with the text of this standard will not necessarily be considered to comply with the safety principles of the standard if, when examined and tested, it is found to have other features that impair the level of safety covered by these req
41、uirements. An appliance employing materials or having forms of construction differing from those detailed in the requirements of this standard may be examined and tested according to the intent of the requirements and, if found to be substantially equivalent, may be considered to comply with the sta

EN 60335-2-77:2006 6 HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES SAFETY Part 2-77: Particular requirements for pedestrian controlled mains-operated lawnmowers 1 Scope This clause of Part 1 is replaced by: This European Standard specifies safety requirements and their verification for the desi
43、gn and construction of pedestrian controlled mains-operated electrical cylinder or rotary lawnmowers with a rated voltage being not more than 250 V single phase. This standard does not apply to lawn trimmers, lawn edge trimmers, lawn edgers, fail mowers, sickle-bar mowers or agricultural mowers. Thi
44、s standard is not applicable to rotary lawnmowers for which the cutting means is a generally circular central drive unit on which is mounted, either one or more non-metallic filaments or one or more non-metallic, pivotally mounted cutting elements. These cutting elements rely on centrifugal force to
45、 achieve cutting, with the kinetic energy of a single cutting element not exceeding 10 J. This document is not applicable to pedestrian controlled mains operated lawnmowers which are manufactured before the date of publication of this document by CENELEC. This standard does not in general take into
46、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 the fact that in many countries additional requirements are specified by the national health authorities, the national authorities respo
47、nsible for the protection of labour, and similar authorities. NOTE 102 This standard does not apply to lawn trimmers, lawn edge trimmers, lawn edgers, flail mowers, sickle-bar mowers, or agricultural mowers. 2 Normative references This clause of Part 1 is applicable except as follows.
