Safety of Household and Similar Electrical Appliances

IEC 60335-2-107:2017+A1:2020 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. This consolidated version consists of the second edition (2017) and its amendment 1 (2020). Therefore, no need to order amendments in addition to this publication.

IEC 60335-2-103:2015+A1:2017+A2:2019 deals with the safety of electric drives for horizontally and vertically moving gates, doors, garage doors and windows for household and similar purposes, their rated voltage being not more than 250 V for single-phase drives and 480 V for other drives. It also covers the hazards associated with the movement of the driven part.
Battery-operated drives and other d.c. supplied drives are within the scope of this standard. Dual supply drives, either mains-supplied or battery-operated, are regarded as battery-operated drives when operated in the battery mode.
Drives not intended for normal household use but which nevertheless may be a source of danger to the public, such as drives intended to be used by laymen in shops, offices, hotels, restaurants, hospitals, in industry and on farms, are within the scope of this standard.
Requirements for drives for doors that may be used in emergency routes and exits are given in Annex AA.
Examples of drives within the scope of this standard are drives for:
- folding doors;
- revolving doors;
- rolling doors;
- roof windows;
- sectional overhead doors;
- swinging and sliding gates or doors.
Drives may be supplied with a driven part.
As far as is practicable, this standard deals with the common hazards presented by drives that are encountered by all persons in and around the home. However, in general, it does not take into account
- persons (including children) whose
- physical, sensory or mental capabilities; or
- lack of experience and knowledge
prevents them from using the drive safely without supervision or instruction;
- children playing with the drive.
Attention is drawn to the fact that in many countries additional requirements are specified by the national authorities responsible for the protection of labour and similar authorities.
This standard does not apply to drives
- for vertically moving garage doors for residential use (60335-2-95);
- for shutters covering doors and windows (including locations where the door is set back from the shutter), awnings, blinds and similar equipment (60335-2-97);
- intended exclusively to be used by trained persons in commercial and industrial premises;
- for specific purposes, such as fire doors;
- for natural smoke exhaust ventilators not used as windows (ISO 21927-2);
- intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas).
This standard does not apply to movement of a pedestrian door where such movement is based solely on stored energy.
This third edition cancels and replaces the second edition published in 2006 and its Amendment 1 (2010). It constitutes a technical revision.
The principal changes in this edition as compared with the second edition of IEC 60335 2 103 are as follows:
- modification of requirements in Clause 20 by introduction of new annexes.
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments. It was established on the basis of the fifth edition (2010) of that standard.
This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as to convert that publication into the IEC standard: Safety requirements for electric drives for gates, doors and windows.
This publication is to be read in conjunction with IEC 60335-1:2013.
This consolidated version consists of the third edition (2015), its amendment 1 (2017) and its amendment 2 (2019). Therefore, no need to order amendments in addition to this publication.

IEC 60335-1:2020 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 60335-1:2020 edition 6.0 and the previous edition IEC 60335-1:2010+AMD1:2013+AMD2:2016 CSV edition 5.2. Futhermore, comments from IEC TC 61 experts are provided to explain the reasons of the most relevant changes.

IEC 60335-1:2020 deals with the safety of electrical appliances for household and similar purposes, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances including direct current (DC) supplied appliances and battery-operated appliances.
