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
61/5366/FDIS 61/5394/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
remain unchanged until the stability date indicated on the IEC website under
"http://webstore.iec.ch" in the data related to the specific publication. At this date, the
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• withdrawn,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.

11.2 Replacement:
Hoods are operated in accordance with the manufacturer’s instructions.
Hoods intended to be placed above a hob are installed so that the distance between their
lowest point and the hob surface is the minimum distance specified in the instructions for
installation. The hob selected for the test shall have uniformly arranged gas burners with a
total heat input equal to 30 kW/m of the gross area (width times depth) of the hood. Vessels
containing water are placed without lids on the gas burners, which are operated to maintain
boiling. The diameters or sizes of the vessels are approximately equal to that of the cooking
zones.
Other hoods are operated in the most severe conditions according to the manufacturer’s
instructions.
Hoods intended to be used in combination with other appliances are tested in combination
with the other appliance in normal operation. Hoods that are not interlocked with the
appliance are also tested with the appliance in operation and the fan switched off.
Hoods are placed in a test corner as follows:
– hoods normally fixed to a wall are fixed to one of the walls, as near to the other wall and
floor or ceiling as is likely to occur, taking into account the instructions;
– hoods normally fixed to a ceiling are fixed to the ceiling as near to the walls as is likely to
occur, taking into account the instructions;
– other hoods are placed as near to the walls as possible.
Dull black-painted plywood approximately 20 mm thick is used for the test corner.
Hoods intended to be used in combination with other appliances are placed as required for
the appliance.

© IEC 2017
Instead of the permissible leakage current for stationary class I appliances, the following
applies:
– for cord and plug connected appliances 0,75 mA or 1 mA per kW rated power input
of the appliance with a maximum of 10 mA,
whichever is higher.
– for other appliances 0,75 mA or 1 mA per kW rated power input
of the appliance with no maximum, whichever
is higher.
For portable class I appliances, instead of the permissible leakage current, the following
applies:
– for cord and plug connected appliances 0,75 mA or 1 mA per kW rated power input
of the appliance with a maximum of 10 mA,
whichever is higher.
15 Moisture resistance
Delete Subclause 15.3 and replace the text by the following:
