IEC 60335-2-107:2017 specifies safety requirements and their verification for the design and construction of robotic battery powered electrical rotary lawnmowers and their peripherals with the rated voltage of the battery being not more than 75 V d.c.
EMC and environmental aspects, except noise, have not been considered in this standard.
This document does not apply to the additional risks associated with internal combustion engine(s), hybrid and fuel cell powered machines and associated charging systems.
This document deals with all the significant hazards presented by battery powered robotic lawnmowers and their peripherals when they are used as intended and under conditions of misuse which are reasonably foreseeable.
Throughout this document, the term machine is used to refer to the robotic lawnmower, separate from its charging station.
This document also provides requirements for the safety of mains powered charging stations and signal sources for perimeter delimiters.
Additional battery operation and charging requirements for robotic lawnmowers, including the charging of lithium ion batteries, are specified in Annex KK which replaces Annexes B and S (except for requirements for non-rechargeable batteries) of Part 1.
This document is not applicable to machines which are manufactured before the date of publication of this document by IEC.
This second edition cancels and replaces the first edition published in 2012. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- Clause 7: Markings and instructions, new requirements for markings, warnings and the instruction manual;
- Clause 8: Protection against access to live parts, new requirements for protection against electric shock for hazardous battery voltages;
- Clause 20: Stability and mechanical hazards, revised requirements for manual controller, manual stop, cutting means stopping time, traction drive stopping and restart procedures, as well as a new standing child foot probe test;
- Clause 22: Construction, revised requirements for disabling devices, working area, perimeter delimiter, sensors and manual controller, as well as new requirements for machine connectors used for charging and contact surfaces used as obstruction sensing devices;
- Clause 24: Components, revised requirements for switches and
- Clause 29: Clearances, creepage distances and solid insulation, revised requirements for the machine and non-mains-powered peripherals.
This standard series is a product family standard series dealing with the safety of appliances and takes precedence over horizontal and generic standards covering the same subject.
This publication is to be used in conjunction with the fifth edition (2010) of IEC 60335-1 and its amendments.

IEC 62841-4-2:2017 applies to hand-held hedge trimmers which are designed for use by one operator for trimming hedges and bushes, including extended-reach hedge trimmers with a maximum length of 3,5 m. The rated voltage is not more than 250 V for single-phase a.c. or d.c. tools, and 480 V for three-phase a.c. tools. The rated input is not more than 3 700 W. The limits for the applicability of this standard for battery tools are given in K.1 and L.1. This standard deals with the hazards presented by tools which are encountered by all persons in the normal use and reasonably foreseeable misuse of the tools. Hand-held electric tools, which can be mounted on a support or working stand for use as fixed tools without any alteration of the tool itself, are within the scope of this standard and such combination of a hand-held tool and a support is considered to be a transportable tool and thus covered by the relevant Part 3.
This standard is not applicable to hedge trimmers with a rotating blade.
This standard is not applicable to scissors type grass shears.
This Part 4-2 is to be used in conjunction with the first edition of IEC 62841-1:2014.
The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests.
It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 36 months from the date of publication
The contents of the corrigendum of June 2018 have been included in this copy.
Key words: Hedge trimmer, Hand-held tool, Safety

IEC 62841-4-1:2017 applies to chain saws for cutting wood and designed for use by one person. This standard does not cover chain saws designed for use in conjunction with a guide-plate and riving knife or in any other way such as with a support or as a stationary or transportable machine.
This standard does not apply to chain saws for tree service as defined in ISO 11681-2; or pole-mounted pruners.
Pole-mounted pruners will be covered by a future part of IEC 62841.
The chain saws covered by this standard are designed only to be operated with the right hand on the rear handle and the left hand on the front handle.
This Part 4-1 is to be used in conjunction with the first edition of IEC 62841-1:2014.
The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests.
It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 36 months from the date of publication.

Applies to hedge trimmers which are designed for use by one operator for trimming hedges and bushes, utilizing one or more linear reciprocating cutter blades. This standard is not applicable to hedge trimmers with a rotating blade.
