Foreword

The text of document 61/3564/FDIS, future edition 7 of IEC 60335-2-7, prepared by IEC Technical

Committee 61, Safety of household and similar electrical appliances, was submitted to the IEC-CENELEC

parallel vote.

A draft amendment was prepared by the Technical Committee CENELEC TC 61, Safety of household

and similar electrical appliances. It was discussed during the meetings of CENELEC TC 61 in Malaga in

June 2007, in Berlin in November 2007, in Kista in June 2008 and in London in December 2008, when it

was decided to submit a draft for an amendment to the Unique Acceptance Procedure.

The combined texts were approved by CENELEC as EN 60335-2-7 on 2009-11-01.

This European Standard supersedes EN 60335-2-7:2003 + corr. July 2003 + A1:2004 + A2:2006.

Endorsement notice

The text of the International Standard IEC 60335-2-7:2008 was approved by CENELEC as a European

Standard with agreed common modifications as given below.
COMMON MODIFICATIONS
1 Scope
p Replace by:
This clause of Part 1 is replaced by the following.

This European Standard deals with the safety of electric washing machines for household and similar

use, that are intended for washing clothes and textiles, their rated voltage being not more than 250 V for

single-phase washing machines and 480 V for other washing machines, in this standard generally

referred to as appliances.

This standard also deals with the safety of electric washing machines for household and similar use

employing an electrolyte instead of detergent. Additional requirements for these appliances are given in

Annex CC.

Appliances not designed 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, on farms and for communal use

in blocks of flats are within the scope of this standard.

This standard deals with the common hazards presented by appliances that are encountered by all

persons in and around the home. However, it does not take into account
– persons (including children) whose
• physical, sensory or mental capabilities, or
• lack of experience and knowledge

prevents them from using the appliance safely without supervision or instruction,

– children playing with the appliance.
This standard does not apply to
– appliances intended to be used in laundrettes,
– appliances intended exclusively for industrial purposes (EN ISO 10472-2),

– appliances intended to be used in locations where special conditions prevail, such as the presence

of a corrosive or explosive atmosphere (dust, vapour or gas).
NOTE 101 Attention is drawn to the fact that

– for washing machines intended to be used in vehicles or on board ships or aircraft, additional 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,

– for washing machines having a separate spin container for water extraction, EN 60335-2-4 is also applicable,

– for washing machines having a drying function, EN 60335-2-11 is also applicable,

– if an appliance within the scope of this standard also incorporates functions that are covered by another Part 2 of EN 60335,

the relevant Part 2 is applied to each function separately, as far as is reasonable. If applicable, the influence of one function on

the other is taken into account.

Part 2-7: Particular requirements for washing machines
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of 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, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). 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. 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 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 IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with an IEC Publication.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

This part of International Standard IEC 60335 has been prepared by IEC technical committee

61: Safety of household and similar electrical appliances.

This seventh edition cancels and replaces the sixth edition published in 2002 and its

Amendment 1 (2004) and Amendment 2 (2006). It constitutes a technical revision.
---------------------- Page: 13 ----------------------

The text of this standard is based on the following documents:
FDIS Report on voting
61/3564/FDIS 61/3653/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 publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its

amendments. It was established on the basis of the fourth edition (2001) of that standard.

NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60335-1.

This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as to

convert that publication into the IEC standard: Safety requirements for electric washing

machines.

NOTE 2 The following annexes contain provisions suitably modified from other IEC or ISO standards.

Annex AA Detergent and rinsing agent IEC 60436 and IEC 60456
Annex BB Ageing test for elastomeric parts ISO 1817

When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies

as far as is reasonable. When this standard states “addition”, “modification” or “replacement”,

the relevant text in Part 1 is to be adapted accordingly.
NOTE 3 The following numbering system is used:

– subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1;

– unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including

those in a replaced clause or subclause;
– additional annexes are lettered AA, BB, etc.
NOTE 4 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 3. When a definition concerns an adjective, the adjective and the

associated noun are also in bold.

A list of all parts of the IEC 60335 series, under the general title: Household and similar

electrical appliances – Safety, can be found on the IEC website.

The committee has decided that the contents of the base publication and its amendments will

remain unchanged until the maintenance result 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 5 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.

The following differences exist in the countries indicated below.
