FOREWORD
This amendment has been prepared by subcommittee 61B: Safety of microwave appliances
for household and commercial use, of 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
61B/494/FDIS 61B/505/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 web site 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• withdrawn,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
• amended.
NOTE The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations can 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.

2 Normative references
Add the following reference to the existing list:
IEC 60335-2-5:2012, Household and similar electrical appliances – Safety – Part 2-5:
Particular requirements for dishwashers
7 Marking and instructions
7.12 Addition:
Add, after the sixth dashed item, the following new dash:
– Metallic containers for food and beverages are not allowed during microwave cooking.
This requirement is not applicable if the manufacturer specifies size and shape of metallic
containers suitable for microwave cooking.
Add, after the last dashed item, the following new dash:
– The instructions for use for fixed appliances and built-in appliances being used equal or
higher than 900 mm above the floor and having detachable turntables shall state that care
© IEC 2014
should be taken not to displace the turntable when removing containers from the
appliance. This is not applicable for appliances with horizontal bottom hinged door.
Add, after the last paragraph, the following new paragraph:
The instructions for microwave ovens that are not in compliance with 22.118 shall state that
the appliance must not be installed equal or higher than 900 mm above the floor.
15 Moisture resistance
Add, after 15.101, the following new subclauses:
15.102 Microwave ovens intended to be built-in as underbench installation and therefore
subject to spillage of liquid from containers onto working surfaces shall be constructed so that
such spillage does not affect their electrical insulation.
Compliance is checked by the following test (see Figure 102).
The microwave oven is built-in as underbench installation as specified by the manufacturer.
The test cabinet including the working surface is tilted to an angle of 2° in the most
unfavourable direction. 500 ml of water containing approximately 1 % NaCl and approximately
0,6 % acid rinsing agent is poured steadily over a period of 20 s through a funnel onto the
complete width of the working surface above the microwave oven. The funnel has an outlet
diameter of approximately 8 mm and the lower edge of its outlet is positioned 20 mm above
the working surface. The centre of the funnel is positioned 15 mm inwards from the leading
edge of the working surface.
The leading edge of the working surface shall be rounded with a radius of 25 mm and the
working surface shall be 50 mm in thickness and free of any drain slots, drain edges, tearing
edges and similar.
Immediately after the test, the appliance shall withstand the electric strength test of 16.3 and
inspection shall show that there is no trace of water on insulation that could result in a
reduction of clearances or creepage distances below the values specified in Clause 29.
The composition of the water containing approximately 1 % NaCl and approximately 0,6 %
acid rinsing agent is described in Annex AA of IEC 60335-2-5:2012.
15.103 Microwave ovens intended to be built-in in cabinets underneath other built-in
appliances and therefore subject to spillage of liquid from filled containers which are handled
during usage of these other appliances shall be constructed so that such spillage does not
affect their electrical insulation.
Compliance is checked by the following test (see Figure 103).
The microwave oven is built-in as specified by the manufacturer. The test cabinet is tilted to
an angle of 2° in the most unfavourable direction. 200 ml of water containing approximately
1 % NaCl and approximately 0,6 % acid rinsing agent is poured steadily over a period of 8 s
through a funnel onto the complete width of the separation board above the microwave oven.
The funnel has an outlet diameter of approximately 8 mm and the lower edge of its outlet is
positioned 20 mm above the separation board. The centre of the funnel is positioned 15 mm
inwards from the leading edge of the separation board.
If the manufacturer states in the installation instructions that a separation board above the
microwave oven is not required, the test shall be repeated while pouring the water containing
approximately 1 % NaCl and approximately 0,6 % acid rinsing agent directly onto the
complete width of the top surface of the microwave oven. The lower edge of the funnel outlet
– 4 – IEC 60335-2-25:2010/AMD1:2014
© IEC 2014
is positioned 20 mm above the top surface of the microwave oven and its centre is
positioned 15 mm inwards from the leading edge of the microwave oven.
Immediately after the test, the appliance shall withstand the electric strength test of 16.3 and
inspection shall show that there is no trace of water on insulation that could result in a
reduction of clearances or creepage distances below the values specified in Clause 29.
The composition of the water containing approximately 1 % NaCl and approximately 0,6 %
acid rinsing agent is described in Annex AA of IEC 60335-2-5:2012.
22 Construction
Add, after 22.117, the following new subclause:
22.118 Inadvertent operations during handling of the container during normal use of fixed
appliances and built-in appliances being used equal or higher than 900 mm above the floor
having detachable turntables shall not lead to a hazardous situation due to falling down
turntables. This is not applicable for appliances with horizontal bottom hinged door.
Compliance is checked by inspection and the following test.
The bearing of the detachable turntable of microwave ovens shall be placed in the most
unfavourable position. A force which will be increased from 0 N up to the maximum of 10 N is
applied vertically downwards to the front edge of the turntable.
During the test, the turntable shall not slide out of the cavity and fall down.
A cylindrical container of borosilicate glass with a maximum thickness of 3 mm, an external
diameter of approximately 190 mm, a height of approximately 90 mm and an outer bottom
curvature of approximately 5 mm is filled with 1 000 g ± 50 g cold water and placed on the
turntable. With a horizontal force applied at the top of the container which will be increased
from 0 N up to the maximum of 10 N an attempt is m
