IEC 60335-2-21:2022 deals with the safety of electric storage water heaters for household and similar purposes and intended for heating water below boiling temperature, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances including direct current (DC) supplied appliances and battery-operated appliances.
This standard also deals with:
appliances not intended for normal household use, but which nevertheless possibly pose a source of danger to the public, such as appliances intended to be used by laymen in shops and on farms;
immersion heater units intended to be retrofitted in a heat exchange closed water heater having provision for retrofitting. Additional requirements are given in Annex AA.
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 authorities responsible for the protection of labour and similar authorities
