4、 meaning of the Gerte- und Produktsicherheitsgesetz (GPSG) (German Equipment and Product Safety Act). This standard has been prepared by Technical Committee CEN/TC 144 “Tractors and machinery for agriculture and forestry” (Secretariat: AFNOR, France), Working Group WG 7 “Garden equipment” (Secretari
5、at: BSI, United Kingdom). The responsible German body involved in its preparation was the Normenausschuss Eisen, Blech- und Metall-waren (Hardware, Tinware and Metal Products Standards Committee), Technical Committee NA 020-00-11 AA Garten- und Rasenpflegegerte. This standard contains specifications
6、 meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 98/37/EC, (valid until 28 December 2009) and the “revised Machinery Directive”, Directive 2006/42/EC, which takes effect on 29 December 2009, and which apply to machines that are either first placed on the
7、 market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of the directives. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this sta
8、ndard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). Amendments This standard differs from DIN EN 14910:2007-08 as follows: a) In subclause 6.1, a NOTE has been included relating to information on noise emission in the sales literature. b) In su
9、bclause 6.2.1, the marking requirements have been brought in line with the Machinery Directive. c) Annex ZA (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 98/37/EC” has been revised. d) Annex ZB (informative) “Relationship between this Europ

34、N 14910:2009-08 EN 14910:2007+A1:2009 (E) 6 1 Scope This European Standard deals with all significant hazards, hazardous situations and events relevant to walk-behind trimmers, powered by a combustion engine, with cutting means using non-metallic filament line or freely pivoting non-metallic cutter(
35、s), of which the cutting elements rely on centrifugal force to achieve cutting with the kinetic energy of a single cutting element not exceeding 10 J, designed for cutting grass or similar plant material, when they are used as intended and under conditions of misuse which are reasonably foreseeable
36、by the manufacturer (see Clause 4). This European Standard is not applicable to: a) walk-behind trimmers with cutting means other than those described above; b) self propelled walk-behind trimmers or walk-behind edge trimmers; c) lawnmowers using non-metallic filament line or freely pivoting non-met
37、allic cutting elements with greater than 10 J kinetic energy; NOTE 1 EN 836 applies for machines using non-metallic filament line or freely pivoting non-metallic cutting elements with greater than 10 J kinetic energy. d) motor mowers using metal or other solid cutting elements. NOTE 2 EN 12733 appli
38、es for machines using metal or other solid cutting elements. EMC and environmental hazards other than noise have not been considered in this European Standard. This European Standard is not applicable to walk-behind trimmers which are manufactured before the date of its publication as EN. NOTE 3 Law
