IEC 60335-2-105:2026 part of IEC 60335 deals with the safety of electric multifunctional shower cabinets and
electric separate multifunctional shower units for household and similar purposes, their
rated voltage being not more than 250 V for single-phase appliances and 480 V for other
appliances including DC supplied appliances.
Appliances not intended for normal household use but which nevertheless can be a source of
danger to the public, such as appliances intended to be used by laymen in hotels, fitness
centres and similar locations, 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
– 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 can be necessary;
– in many countries, additional requirements are specified by the national health authorities,
the national water supply authorities, the national authorities responsible for the protection
of labour and similar authorities;
– in many countries, mechanical strength, impact resistance and shattering properties of
shower enclosures can be covered by national regulations.
If an appliance incorporates a part that is within the scope of IEC 60598 series or IEC 62368
series, the part is tested in accordance with the relevant standard as far as reasonable.
This standard does not apply to
– instantaneous water heaters used for showering (IEC 60335-2-35);
– shower-boost pumps (IEC 60335-2-41);
– appliances intended for medical 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).
