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
61/5324/FDIS 61/5385/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• withdrawn,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
• amended.
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.

IMPORTANT – The “colour inside” logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct understanding
of its contents. Users should therefore print this publication using a colour printer.

11.3 Addition:
Where the external accessible surfaces are suitably flat and access permits, then the test
probe of Figure 103 is used to measure the temperature rises of external accessible
surfaces specified in Table 101. The probe is applied with a force of 4 N ± 1 N to the surface
in such a way that the best possible contact between the probe and the surface is ensured.
The measurement is performed after a contact period of 30 s.
The probe may be held in place using a laboratory stand clamp or similar device. Any
measuring instrument giving the same results as the probe may be used.
11.7 Add the following new text after the first paragraph:
Steady conditions are considered to exist 60 min after reaching the temperatures defined for
normal operation.

– the underside of appliances intended to be used on a working surface or floor;
– the rear surface of appliances;
– surfaces that are inaccessible to a 75 mm diameter probe having a hemispherical end;
– functional surfaces and adjacent surfaces.
b
The temperature rise on external accessible surfaces up to a distance of 100 mm from adjacent surfaces of
the appliance, (see Figure 102) may exceed the limits by up to 25 K, but the relevant part shall then be
marked with symbol IEC 60417-5041 (2002-10) or the equivalent text.
c
Metal is considered coated when a coating having a minimum thickness of 90 µm made by enamel or non-
substantially plastic coating is used.
d
The temperature rise limit of plastic also applies for plastic material having a metal finish of thickness less
than 0,1 mm.
