1 Scope
This International Standard deals with the safety of electrical appliances for household and similar purposes, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances.
Appliances not intended for normal household use but which nevertheless may 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.
Note 1: Examples of such appliances are catering equipment, cleaning appliances for industrial and commercial use, and appliances for hairdressers.
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 2: 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, the national water supply authorities and similar authorities.
Note 3: 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);
– audio, video and similar electronic apparatus (GB 8898);
– appliances for medical purposes (GB 9706.1);
– hand-held motor-operated electric tools (GB 3883.1);
– personal computers and similar equipment (GB 4943);
– transportable motor-operated electric tools (GB 13960).

frequency range assigned to the appliance by the manufacturer, expressed by its lower and upper limits.
3.1.9 normal operation
conditions under which the appliance is operated in normal use when it is connected to the supply mains.
3.1.10 rated impulse voltage
voltage derived from the rated voltage and the overvoltage category of the appliance, characterizing the specified withstand capability of its insulation against transient over-voltages.
3.1.11 dangerous malfunction
unintended operation of the appliance that may impair safety.
3.2
3.2.1 detachable cord
flexible cord, for supply or interconnection, intended to be connected to the appliance by means of a suitable appliance coupler.
3.2.2 interconnection cord
external flexible cord provided as part of a complete appliance for purposes other than connection to the supply mains.
Note: A remote hand-held switching device, an external interconnection between two parts of an appliance and a cord connecting an accessory to the appliance or to a separate signalling circuit are examples of interconnection cords.
3.2.3 supply cord
flexible cord, for supply purposes, that is fixed to the appliance.
3.2.4 type X attachment
method of attachment of the supply cord such that it can easily be replaced.
Note: The supply cord may be specially prepared and only available from the manufacturer or its service agent.
A specially prepared cord may include a part of the appliance.
3.2.5 type Y attachment
method of attachment of the supply cord such that any replacement is intended to be made by the manufacturer, its service agent or similar qualified person
3.2.6 type Z attachment
method of attachment of the supply cord such that it cannot be replaced without breaking or destroying the appliance
3.2.7 supply leads
set of wires intended for connecting the appliance to fixed wiring and accommodated in a compartment within or attached to the appliance
