Scope

This clause of Part 1 is replaced by the following. This International Standard deals with the safety of electric powered walk-behind and handheld lawn trimmers and lawn edge trimmers@ with cutting element(s) of non-metallic filament line or freely pivoting non-metallic cutter(s)@ with a kinetic energy of not more than 10 J each@ used by a standing operator for cutting grass@ their rated voltage being not more than 250 V for a.c. or 50 V d.c.. In this standard@ hand-held and walk-behind lawn trimmers and lawn edge trimmers are referred to collectively as trimmer(s). So far as is practicable@ this standard deals with the common hazards presented by trimmers which are encountered by all persons in the normal use and reasonably foreseeable misuse of the trimmers. NOTE 101 Attention is drawn to the fact that in many countries additional requirements are specified by the national health authorities@ the national authorities responsible for the protection of labour@ the national water supply authorities and similar authorities. This standard does not apply to ?C scissor type or lawn trimmers and lawn edge trimmers with cutting means other than those described above; ?C self-propelled lawn trimmers or lawn edge trimmers; ?C lawn trimmers or lawn edge trimmers which do not have a distance of at least 600 mm between the cutting means control and the cutting head; ?C battery-powered trimmers fitted with batteries that have to be removed for charging. NOTE 102 Requirements for tools with this type of battery can be found in Annexes K and L of IEC 60745-1. EMC and environmental aspects@ except noise@ have not been considered in this standard. NOTE 103 The method of calculating the kinetic energy for the purposes of this standard is given in 22.103.
