5. Title, number of pages  and language(s)  of the notified document:  BOS IEC 60335 -2-
40:2013, Household and similar electrical appliances  - Safety - Part 2 -40: Particular 
requirements for fans Scope (155 pages, in English).  
6. Descr iption of content:  This part of IEC 60335 deals with the safety of electric heat 
pumps, including sanitary hot water heat pumps, air conditioners and dehumidifiers 
incorporating motor -compressors and hydronic room fan coils, their maximum rated 
voltages be ing not more than 250 V for single phase appliances and 600 V for all 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 for use in shops, in light industry and 
on farms, are within the scope of this standard.  
This standard also applies to electric heat pumps, air conditioners and dehumidifiers 
containing flammable refrigerant. Flammable refrigerants are defined in 3.121.  
The appliances referenced ab ove may consist of one or more factor y made assemblies. If 
provided in more than one assembly, the separate assemblies are to be used together, and 
the requirements are based on the use of matched assemblies.  
NOTE 101 A definition of "motor compressor " is given in IEC 60335 -2-34, which includes 
the statement that the term motor -compressor is used to designate either a hermetic 
motor -compressor or semi -hermetic motor -compressor.  
NOTE 102 Requirements for refrigeration safety are covered by ISO 5149, and 
requirements for containers intended for storage of the heated water included in sanitary G/TBT/N/BWA/48  
 
- 2 - 
 
  hot water heat pumps are, in addition covered by IEC 60335 -2-21. 
This standard does not take into account chemicals other than group A1, A2, or A3 as 
defined by ANSI/ASHR AE [ISO] classification.  
This standard specifies particular requirements for the use of flammable refrigerants. 
Unless specifications are covered by this standard, including the annexes, requirements for 
refrigerating safety are covered by ISO 5149. The se ctions and clauses in ISO 5149 of 
particular concern to this standard are as follows:  
 Section 3: "Design and construction equipment " applies to all appliances and 
systems.  
 Section 4: "Requirements for utilization " applies to appliances and systems which 
are for "similar electric appliances ", i.e. commercial and light industrial.  
 Section 5: "Operating procedures " applies to appliances and systems which are for 
"similar electric appliances ", i.e. commercial and light industrial.  
Supplementary heaters, or a pr ovision for their separate installation, are within the scope 
of this standard, but only heaters which are designed as a part of the appliance package, 
the controls being incorporated in the appliance  
NOTE 103 Attention is drawn to the fact that  for applia nces intended to be used in vehicles 
or on board ships or aircraft  additional requirements may be necessary;  for appliances 
subjected to pressure, additional requirements may be necessary;  in many countries, 
additional requirements are specified by the nat ional health authorities responsible for the 
protection of labour and national authorities responsible for storage, transportation, 
building constructions and installations.  
NOTE 104 This standard does not apply to : 
 humidifiers intended for use with heatin g and cooling equipment (IEC 60335 -2-88); 
 appliances designed exclusively for industrial processing;  
 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).
