1 Scope
This clause of GB 4706.1-2005 is replaced by the following.
This part deals with the safety of electric fans for household and similar purposes, their rated voltage being not more than 250V for single-phase appliances and 480V for other appliances.
NOTE 101: Examples of fans that are within the scope of this standard are
- ceiling fans;
- duct fans;
- partition fans;
- pedestal fans;
- table fans.
This standard also applies to separate controls supplied with fans.
Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended for use 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 appliances that are encountered by all persons in and around the home.
However, in general, it does not take into account:
- the use of appliances by young children or infirm persons without supervision;
- playing with the appliance by young children.
NOTE 102: 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;
- in many countries additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour and similar authorities.
NOTE 103: This standard does not apply to
- appliances intended exclusively for industrial purposes;
- appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);
- fans incorporated in other appliances.
