13、ted electric tools, of IEC TC 61, Safety of household and similar electrical appliances, together with the common modifications prepared by the Technical Committee CENELEC TC 61F, Safety of hand-held and transportable motor-operated electric tools, was submitted to the CENELEC formal vote and was ap
14、proved as EN 60335-2-77 on 2010-09-01. This document supersedes EN 50338:2006 and EN 60335-2-77:2006. The text of EN 60335-2-77:2006 has been revised by CLC/TC 116/WG 5, Garden appliances, to add the mechanical requirements and bring this standard in line with the Machinery Directive 2006/42/EC. Add
15、itionally the safety requirements for battery powered lawnmowers have been included to replace EN 50338:2006; therefore the title is renamed. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and CENELEC shall not be held respon
16、sible for identifying any or all such patent rights. The following dates were fixed: latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2011-09-01 latest date by which the national standards conflicting with th
17、e EN have to be withdrawn (dow) 2013-09-01 This Part 2-77 is to be used in conjunction with EN 60335-1. This Part 2-77 supplements or modifies the corresponding clauses of EN 60335-1, so as to convert it into the European Standard: Particular requirements for pedestrian-controlled walk-behind electr
18、ically powered lawn mowers. When a particular subclause of Part 1 is not mentioned in this Part 2-77, that subclause applies as far as is reasonable. When this standard states “addition”, “modification” or “replacement”, the relevant text of Part 1 is to be adapted accordingly. This European Standar
19、d has been prepared under Mandate M/396 given to CENELEC by the European Commission and the European Free Trade Association and covers essential requirements of EU Directive 2006/42/EC. See Annex ZZ. There are no special national conditions causing a deviation from this European Standard, other than
20、 those listed in Annex ZA to EN 60335-1. There are no national deviations from this European Standard, other than those listed in Annex ZB to EN 60335-1. Other harmonised standards referred to in this European Standard are listed in Annex ZC of Part 1 and this Part 2. The annex lists the valid editi
21、on of those documents at the time of issue of this EN. All references are however to be understood as references to the latest edition. BS EN 60335-2-77:2010- 3 - EN 60335-2-77:2010 The following numbering system is used: subclauses that are numbered starting from 101 are additional to those in Part

The machinery concerned and the extent to which hazards, hazardous situations and events are covered is as indicate
39、d in the scope of this document. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the other standards, for machines which have been built and designed to the provisions of this type
40、 C standard. BS EN 60335-2-77:2010EN 60335-2-77:2010 - 8 - 1 Scope This clause of Part 1 is replaced by the following. This European Standard specifies safety requirements and their verification for the design and construction of pedestrian controlled walk-behind electrically powered lawnmowers. Thi
41、s standard applies in conjunction with EN 60335-1. This European Standard does not apply to lawn trimmers, lawn edge trimmers, lawn edgers, flail mowers, scrub cutters, automatic (robot) lawn mowers, sickle-bar mowers, agricultural mowers, trailing seat/sulky units, ride-on machines or non-powered l
42、awnmowers 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 achieve cutting, with
43、 the kinetic energy of a single cutting element not exceeding 10 J, battery powered lawnmowers with a rated voltage of the battery more than 42 V d.c. Requirements for battery chargers, including those incorporated into the machine are dealt with in EN 60335-2-29. This European Standard is not appli
