This document 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.
