IEC 60335-2-51:2023 deals with the safety of electric stationary circulation pumps for house-hold and similar purposes intended for use in heating systems or in service water sys-tems, 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. The hydraulic and electrical parts of the pump can be in the same enclosure, so that the water flows through the motor and serves as a coolant, or they can be separated. Appliances not intended for normal household use, but that nevertheless can be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard. As far as is practicable, this standard deals with the common hazards presented by ap-pliances that are encountered by all persons in and around the home. However, in gen-eral, it does not take into account:

- children playing with the appliance.
Attention is drawn to the fact that
