IEC 62841-4-3-2020 Electric motor-operated hand-held tools, transportable tools and lawn and garden machinery – Safety – Part 4-3: Particular requirements for pedestrian controlled walk-behind lawnmowers. This clause of Part 1 is applicable, except as follows: Addition: This document applies to the design of pedestrian controlled walk-behind – cylinder lawnmowers; and – rotary lawnmowers equipped with – metallic cutting means; and/or – rigid non-metallic cutting means; and/or – non-metallic cutting means with one or more cutting elements pivotally mounted on a generally circular drive unit, where these cutting elements rely on centrifugal force to achieve cutting, and have a kinetic energy for each single cutting element of greater than 1 0 J. NOTE 1 01 Machines that have non-metallic cutting means and a kinetic energy for each single cutting element of less than or equal to 1 0 J are considered to be lawn trimmers. This document does not apply to – robotic lawnmowers; – remote-controlled lawnmowers; – flail mowers or flail-type attachments; – scissors type lawnmowers; – grassland mowers; – sickle bar mowers; – towed/semi-mounted grass-cutting machines; – scrub-clearing machines; – lawn trimmers and lawn edge trimmers; – lawn edgers; – grass trimmers; – brush cutters; – brush saws; – agricultural mowers; – trailing seat/sulky units; – ride-on machines; – non-powered lawnmowers; – combustion engine powered lawnmowers; – hybrid and fuel cell powered machines and associated charging systems; and – garden tractors or their attachments. NOTE 1 02 Robotic lawnmowers are covered by IEC 60335-2-1 07, and will be covered by a future part of IEC 62841 . NOTE 1 03 Lawn trimmers and lawn edge trimmers are covered by IEC 60335-2-91 . NOTE 1 04 Lawn trimmers, lawn edge trimmers, grass trimmers, brush cutters and brush saws will be covered by a future part of IEC 62841 . NOTE 1 05 Lawn edgers will be covered by a future part of IEC 62841 . 2 Normative references This clause of Part 1 is applicable, except as follows: Addition: IEC 60664-3, Insulation coordination for equipment within low-voltage systems – Part 3: Use of coating, potting or moulding for protection against pollution IEC 60664-4, Insulation coordination for equipment within low-voltage systems – Part 4: Consideration of high-frequency voltage stress IEC 61 058-2-6:201 8, Switches for appliances – Part 2-6: Particular requirements for switches used in electric motor-operated hand-held tools, transportable tools and lawn and garden machinery IEC 61 672-1 , Electroacoustics...
