BS EN 14910:2007+A1:2009EN 14910:2007+A1:2009 (E) 5 Introduction This European Standard is a type C standard as stated in EN ISO 12100-1. The machinery concerned and the extent to which hazards, hazardous
28、situations and events are covered are indicated in the scope of this European Standard. 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 provisions of the other standards, for m
29、achines that have been designed and built according to the provisions of this type C standard. BS EN 14910:2007+A1:2009EN 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 combust
30、ion engine, with cutting means using non-metallic filament line or freely pivoting non-metallic cutter(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 ma
31、terial, when they are used as intended and under conditions of misuse which are reasonably foreseeable 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
32、or walk-behind edge trimmers; c) lawnmowers using non-metallic filament line or freely pivoting non-metallic 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
33、10 J kinetic energy. d) motor mowers using metal or other solid cutting elements. NOTE 2 EN 12733 applies 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 applica
34、ble to walk-behind trimmers which are manufactured before the date of its publication as EN. NOTE 3 Lawn trimmers and lawn edge trimmers (electric powered) are dealt with in EN 786, grass trimmers (internal combustion engine powered) are dealt with in EN 11806 and lawn mowers (internal combustion en
35、gine powered) are dealt with in EN 836. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including an

46、cant hazards, the significant hazardous situations and events covered by this European Standard, that have been identified by risk assessment as being significant for this type of machine, and which require specific action to eliminate or to reduce the risk.
