Defines safety requirements and their verification for the design and construction of electric powered walk-behind and hand-held 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 75 V d.c..

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 electric powered walk-behind and hand-held 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 75 V d.c..

NOTE 101 The method of calculating the kinetic energy for the purposes of this standard is given in 22.103.

In this European Standard, hand-held and walk-behind lawn trimmers and lawn edge trimmers are referred to collectively as machine(s).

This European Standard does not apply to

• scissor type or lawn trimmers and lawn edge trimmers with cutting means other than those described above;

• lawn trimmers and lawn edge trimmers with collecting devices;

• self-propelled lawn trimmers or lawn edge trimmers;

EMC and environmental aspects, except noise, have not been considered in this European Standard.

This European Standard does not apply to chargers as covered by EN 60335-2-29.

This European Standard does not apply to batteries as covered by EN 62133.

This European Standard deals with all the significant hazards presented by hand-held and walk-behind lawn trimmers and lawn edge trimmers when they are used as intended and under conditions of misuse which are reasonably foreseeable.
