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

61/4279/FDIS 61/4302/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• withdrawn,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 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.

Replace the title of Clause 3 (but not the clause number), by the following:
Terms and definitions
15 Moisture resistance
15.101 Replace the second paragraph of the test specification with the following:

---------------------- Page: 4 ----------------------
60335-2-7 Amend.1 © IEC:2011 – 3 –


The appliance is operated under the conditions specified in Clause 11 but at rated voltage for

one complete cycle with the programme that results in the longest period of operation. A

quantity of detergent necessary to cause foaming is added. The composition of the detergent

is specified in Annex AA.


19 Abnormal operation


19.9 Replace the existing text by the following:


19.9 Addition:

The running overload test is carried out on appliances that have overload protective devices
incorporating electronic circuits to protect the windings of the drum motor. However, the test
is not carried out if the protective device senses the winding temperature directly.
NOTE Measuring winding resistance or winding current is not directly measuring the winding temperature.
The appliance is operated under the conditions of Clause 11 for one cycle. The load is then
increased so that the current through the motor windings is raised by 10 %. The appliance is
operated again for the same cycle, the supply voltage being maintained at its original value.
The load is again increased and the test is repeated until the protective device incorporating
the electronic circuit operates or the motor stalls.
20 Stability and mechanical hazards
20.102 Add the following new paragraph to the test specification, before the last paragraph:
If compliance relies on the operation of an electronic circuit, the test is repeated with the
fault conditions in a) to g) of 19.11.2 applied one at a time to the electronic circuit.
20.104 Add the following new paragraph after the second paragraph of the test specification:
If compliance relies on the operation of an electronic circuit, the test is repeated under the
following conditions applied separately:
– the fault conditions in a) to g) of 19.11.2 applied one at a time to the electronic circuit;
– the electromagnetic phenomena tests of 19.11.4.2 and 19.11.4.5 applied to the appliance.
After the Note, add the following new paragraph:

If the electronic circuit is programmable, the software shall contain measures to control the
fault/error conditions specified in Table R.1 and is evaluated in accordance with the relevant
requirements of Annex R.
20.105 Replace the test specification and the Note by the following:
NOTE The rotational kinetic energy is calculated in accordance with the formula in 20.104.
Compliance is checked by the following test.
The appliance is supplied at rated voltage and operated in accordance to 20.1 empty or filled
as specified for normal operation, whichever is more unfavourable. A force not exceeding
50 N is applied to the lid or door in an attempt to open it, as in normal use.
If compliance relies on the operation of an electronic circuit, the test is repeated under the
following conditions applied separately:

– 4 – 60335-2-7 Amend.1 © IEC:2011


– the fault conditions in a) to g) of 19.11.2 applied one at a time to the electronic circuit;

– the electromagnetic phenomena tests of 19.11.4.2 and 19.11.4.5 applied to the appliance.


If the lid or door opens, the drum speed shall be no higher than 60 r/min within 7 s of opening

the lid or door by 50 mm. In addition, if the appliance is loaded from the front, the motor shall

become de-ene
