FOREWORD
This amendment has been prepared by IEC technical committee 61: Safety of household and
similar electrical appliances.
The text of this amendment is based on the following documents:
FDIS Report on voting
61/3692/FDIS 61/3746/RVD
Full information on the voting for the approval of this amendment can be found in the report
on voting indicated in the above table.
The committee has decided that the contents of this amendment and the base publication will

publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or

NOTE The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations may need a transitional period following publication of a new, amended or revised IEC publication in
which to make products in accordance with the new requirements and to equip themselves for conducting new or
revised tests.
It is the recommendation of the committee that the content of this publication be adopted for implementation
nationally not earlier than 12 months or later than 36 months from the date of publication.

Title
Replace the title by the following:
HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
SAFETY –
Part 2-31: Particular requirements for range hoods and other cooking
fume extractors
INTRODUCTION
Replace the fifth paragraph by the following:
When a part 2 standard does not include additional requirements to cover hazards dealt with
in Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
60335-2-31 Amend. 2 © IEC:2008 – 3 –
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
1 Scope
Replace the second paragraph by the following:
This International Standard deals with the safety of electric range hoods and other cooking
fume extractors intended for installing above, beside, behind or under household cooking
ranges, hobs and similar cooking appliances, their rated voltage being not more than 250 V.
Replace the two dashed items in the fourth paragraph by the following:
– 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.
3 Definitions
Add the following new definition:
3.102
down-draft system
a ventilation system intended for installation adjacent to household cooking ranges, hobs and
similar cooking appliances that draws vapour down into an internal exhaust duct
NOTE The filtered air may be discharged back into the room or ducted away.
5 General conditions for the tests
Add the following subclause:
5.7 Addition:
For down-draft systems, the tests specified in Clauses 11 and 13 are carried out at an
ambient temperature of 40 °C ± 2 °C.
Add the following new subclause:
5.101 Down-draft systems intended to be installed above the cooking surface are tested as
specified for range hoods.
7 Marking and instructions
7.1 In the addition, replace “5012 of IEC 60417-1” by “IEC 60417-5012 (2002-10)”.
7.12 Add the following dashed item:

– 4 – 60335-2-31 Amend. 2 © IEC:2008
– CAUTION: Accessible parts may become hot when used with cooking appliances.
7.12.1 Replace the second dashed item by the following:
– the minimum distance between the supporting surface for the cooking vessels on the hob
and the lowest part of the range hood. (When the range hood is located above a gas
appliance, this distance shall be at least 65 cm. If the instructions for installation for the
gas hob specify a greater distance, this has to be taken into account. The distance of
65 cm can be reduced for
– non-combustible parts of range hoods, and
– parts operating at safety extra low voltage,
provided these parts do not give access to live parts if deformed).
