This clause of GB 4706.1-2005 is replaced by the following.
This part of GB 4706 deals with the safety of electric battery chargers for household and similar use having an output at safety extra-low voltage, their rated voltage being not more than 250 V.
Battery chargers not intended for normal household use, but which nevertheless may be a source of danger to the public, such as battery chargers intended for use in garages, shops, light industry and on farms, are within the scope of this standard.
As far as is practicable, this part deals with the common hazards presented by appliances 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 appliance safely without supervision or instruction;
— Children playing with the appliance.
Note 101: Attention is drawn to the fact that:
— For appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary;
