3. Notified under Article 2.9.2 [X], 2.10.1 [   ], 5.6.2 [   ], 5.7.1 [   ], other:   
4. Products covered (HS or CCCN where applicable, otherwise national tariff heading. 
ICS numbers may be provided in addition, where applicable):  Household and similar 
electrical appliances - Safety, Part 2-21: Particular requirements for storage water heaters ICS: 91.140.65; 13.120 
5. Title, number of pages and language(s) of the notified document:  Household and similar 
electrical appliances - Safety, Part 2-21: Particular requirements for storage water heaters (21 pages in English) 
6. Description of content:  This International Standard deals with the safety of electric storage 
water heaters for household a nd similar purposes and intend ed 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.  
Appliances not intended for normal household use but that nevertheless may be a source of 
danger to the public, such as appliances intended to be used by laymen in shops and in light 
industry and farms, are within  the scope of the standard. 
As far as is practicable, th is standard deals with the co mmon hazards presented by the 
appliances that are encountered by all persons in and around the home. However, in general, it 
does not take into account  G/TBT/N/BWA/4 
Page 2  
 
  - Persons (including children) whose 
- Physical , sensory or mental capabilities; or  
- Lack of experience and knowledge preven ts them from using the appliance safely 
 without supervision or instruction; 
- Children playing with the appliance. Note 101 Attention is drawn to the fact that 
- For the appliances intended to be used at high altitudes, additional requirements may 
 be necessary; 
- For the appliances intended to be used in  vehicles or on board ships or aircraft, 
 additional requiremen ts may be necessary; 
- In many countries additional requireme nts are specified by the national health 
 authorities, the national authorities res ponsible for the protection of labour and 
 similar authorities; 
- In many countries regulations exist for th e installation of equipment connected to the 
 water mains. 
Note 102 This standard does not apply to  
- Appliances for boiling water (IEC 60335-2-15); 
- Instantaneous water heaters (IEC 60335-2-35); 
- Commercial dispensing appliances a nd vending machines (IEC 60335-2-75); 
- Appliances intended exclusively for industrial purposes; - Appliances intended to be used in locati ons where special conditions prevail, such as 
 the presence of a corrosive or explos ive atmosphere (dust, vapour or gas).
