EN IEC 60335-2-40:2024/A11:2024 modifies the European standard EN IEC 60335-2-40:2024.
IEC 60335-2-40 deals with the safety of electric heat pumps, sanitary hot water heat pumps and air conditioners, incorporating motor compressors as well as hydronic fan coils units, dehumidifiers (with or without motor compressors), thermoelectric heat pumps and partial units. Their maximum rated voltage is not more than 300 V for single-phase appliances and 600 V for multi-phase appliances.
Appliances and machines intended to be used by expert or trained users in shops, in light industry and on farms, and appliances and machines which are declared to be for commercial use by lay persons are covered by IEC 60335-2-40..
IEC 60335-2-40 deals with the reasonably foreseeable hazards presented by appliances and machines that are encountered by all persons. However, in general, it does not take into account:
— children playing with the appliance,
— the use of the appliance by very young children,
— the use of the appliance by young children without supervision.
