Part 2-7: Particular requirements for washing machines

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization
for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60335-2-7 has been prepared by IEC technical committee 61:
Safety of household and similar electrical appliances.
This fifth edition cancels and replaces the fourth edition published in 1993, amendment 1
(1998) and amendment 2 (1999). This fifth edition constitutes a technical revision.
The text of this standard is based on the fourth edition, amendments 1 and 2 and the following
documents:
FDIS Report on voting
61/1644/FDIS 61/1740/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This part 2 is intended to be used in conjunction with the latest edition of IEC 60335-1 and its
amendments. It was established on the basis of the third edition (1991) of that standard.
This part 2 supplements or modifies the corresponding clauses of IEC 60335-1 so as to convert
it into the IEC standard: Safety requirements for electric washing machines.
Where a particular subclause of part 1 is not mentioned in this part 2, that subclause applies
as far as is reasonable. Where this standard states "addition", "modification" or "replacement",
the relevant text in part 1 is to be adapted accordingly.

NOTE 1 The following print types are used:

– requirements: in roman type;

– test specifications: in italic type;

– notes: in small roman type;

Words in bold in the text are defined in clause 2.

NOTE 2 Subclauses which are additional to those in part 1 are numbered starting from 101. Annexes which are
additional to those in part 1 are lettered AA, BB, etc.

The following additional differences exist in some countries:

– 2.2.9: Different size cloths are used. The initial water temperature for machines without heating elements and
without a wringer is 71 °C (USA).

– 6.1: Class 01 appliances are permitted (China and Japan).
– 6.2: IPX0 appliances are permitted (Canada and USA).
– 11.7: The test durations are different (USA).
– 15.101: The test is carried out differently (USA).
– 19.7: Appliances without a programmer are operated until steady conditions are established (USA).
– 19.101: A redundant set of contacts is not required as shown in note 2. Operation without water as specified in
note 4 is not considered an abnormal condition (USA).
– 22.6: A different test is made (USA).
The test is carried out at twice the permissible inlet pressure or 2,0 MPa, whichever is greater (Norway).
The test is not conducted (USA).
– Annex AA: A different detergent is used (USA).
– Annex BB: Other tests are made on elastomeric parts (USA).
A bilingual version of this standard may be issued at a later date.

SAFETY OF HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –

Part 2-7: Particular requirements for washing machines

1 Scope
This clause of part 1 is replaced by:

This standard deals with the safety of electric washing machines for household and similar
purposes, intended for washing clothes and textiles, their rated voltage being not more than
250 V for single-phase appliances and 480 V for other appliances.
NOTE 1 Washing machines may incorporate means for heating water, water extraction and drying.
NOTE 2 Washing machines having a spin extraction function also have to comply with the relevant requirements
of IEC 60335-2-4.
Washing machines having a drying function also have to comply with the relevant requirements of IEC 60335-2-11.
NOTE 3 Washing machines supplied with electricity together with other forms of energy are also within the scope
of this standard.
Appliances not intended for normal household use but which nevertheless may be a source of
danger to the public, such as appliances intended to be used by laymen in shops, in light
industry and on farms, are within the scope of this standard.
NOTE 4 Examples of such appliances are washing machines for communal use in blocks of flats or in
launderettes.
So far as is practicable, this standard deals with the common hazards presented by appliances
which are encountered by all persons in and around the home.
This standard does not in general take into account
– the use of appliances by young children or infirm persons without supervision;
– playing with the appliance by young children.
NOTE 5 Attention is drawn to the fact that:
– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be
necessary;
– for appliances intended to be used in tropical countries special requirements may be necessary;
– in many countries additional requirements are specified by the national health authorities, the national

authorities responsible for the protection of labour, the national water supply authorities and similar authorities.
NOTE 6 This standard does not apply to:
– appliances designed exclusively for industrial purposes;
– appliances intended to be used in locations where special conditions prevail, such as
...
