BS EN 60335-2-98:2003+A2:2008 Household and similar electrical appliances. Safety. Particular requirements for humidifiers
BS EN 60335-2-98 deals with the safety of electric humidifiers for household and
similar use, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances.
Examples of appliances that are within the scope of the standard are
– appliances that atomize water
– appliances that evaporate water by heating;
– appliances that blow air through a moist element.
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 BS EN 60335-2-98.
As far as is practical, BS EN 60335-2-98 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.
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.
BS EN 60335-2-98 does not apply to:
- Humidifiers intended for use with heating, ventilation or air-conditioning systems (IEC 60335-2-88);
- Appliances for medical purposes (BS EN 60601)
- 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).
