Household and similar electrical appliances - Safety - Part 2-7: Particular requirements for washing machines

IEC 60335-2-7:2019 is available as IEC 60335-2-7:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60335-2-7:2019 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 appliances and 480 V for other 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. Guidance is given in Annex DD for requirements that can be used to ensure an acceptable level of protection against electrical and thermal hazards for washing machines fitted with a power driven wringer. 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.
Examples of such appliances are washing machines for communal use in blocks of flats or in launderettes. As far as is practicable, this standard deals with the common hazards presented by washing machines that are encountered by all persons in and around the home. However, in general, 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.
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.
This standard does not apply to:
– washing machines intended exclusively for industrial purposes (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);
– washing machines incorporating steam generating devices in which steam is produced at a pressure exceeding 50 kPa.
This eighth edition cancels and replaces the seventh edition published in 2008, Amendment 1: 2011 and Amendment 2:2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
– requirements for steam generators in 3.1.9, 3.6.101, 19.101, 22.106, 22.107;
– additional definitions for washing machine types in 3.5.101,3.5.102, 3.5.103;
– revised temperature limits for external accessible surfaces in 11.3 and 11.8;
– revised test procedure for the spillage test in 15.2;
– additional requirements for appliances that are controlled by programmable electronic circuits that limit the number of heating elements and motors from being energised at the same time, Subclause 22.108.
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 fifth edition (2010) of that standard.

Appareils électrodomestiques et analogues - Sécurité - Partie 2-7: Exigences particulières pour les machines à laver le linge

IEC 60335-2-7:2019 est disponible sous forme de IEC 60335-2-7:2019 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 60335-2-7:2019 traite de la sécurité des machines à laver le linge électriques pour usages domestiques et analogues destinées à laver des vêtements et des textiles, dont la tension assignée n'est pas supérieure à 250 V pour les appareils monophasés et à 480 V pour les autres appareils. La présente norme traite également de la sécurité des machines à laver le linge électriques pour usages domestiques et analogues employant un électrolyte à la place d’un détergent. Les exigences complémentaires pour ces appareils sont données à l’Annexe CC. Des recommandations sont données à l’Annexe DD pour les exigences qui peuvent être utilisées pour assurer un niveau acceptable de protection contre les dangers électriques et thermiques pour les machines à laver le linge comportant une essoreuse à rouleaux entraînés par moteur. Les appareils qui ne sont pas destinés à un usage domestique normal mais qui peuvent néanmoins constituer une source de danger pour le public, tels les appareils destinés à être utilisés par des utilisateurs non avertis dans des magasins, chez des artisans et dans des fermes, sont compris dans le domaine d'application de la présente norme. Les machines à laver le linge mises à la disposition commune des utilisateurs dans des immeubles d'habitation ou dans les laveries automatiques sont des exemples de tels appareils. Dans la mesure du possible, la présente norme traite des dangers ordinaires présentés par les machines à laver le linge qui sont encourus par tous les individus à l'intérieur et autour de l'habitation. Cependant, la présente norme ne tient pas compte en général:
– des personnes (y compris des enfants) dont les capacités physiques, sensorielles ou mentales ou le manque d’expérience et de connaissance les empêchent d’utiliser l’appareil en toute sécurité sans surveillance ou instruction;
– de l’utilisation de l’appareil comme jouet par des enfants.
L’attention est attirée sur le fait que:
– pour les machines à laver le linge destinées à être utilisées dans des véhicules ou à bord de navires ou d’avions, des exigences supplémentaires peuvent être nécessaires;
– dans de nombreux pays, des exigences supplémentaires sont spécifiées par les organismes nationaux de la santé, par les organismes nationaux responsables de la protection des travailleurs, par les organismes nationaux responsables de l'alimentation en eau et par des organismes similaires.
La présente norme ne s’applique pas:
– aux machines à laver le linge prévues exclusivement pour des usages industriels (ISO 10472-2);
– aux appareils destinés à être utilisés dans des locaux présentant des conditions particulières, telles que la présence d'une atmosphère corrosive ou explosive (poussière, vapeur ou gaz);
– aux machines à laver le linge équipées de dispositifs générant de la vapeur qui est produite à une pression dépassant 50 kPa.
Cette huitième édition annule et remplace la septième édition parue en 2008, l'Amendement 1:2001 et l'Amendement 2:2016. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
– exigences relatives aux générateurs de vapeur, en 3.1.9, 3.6.101, 19.101, 22.106 et 22.107;
– définitions supplémentaires concernant les types de machines à laver le linge, en 3.5.101, 3.5.102 et 3.5.103;
– révision des limites de température pour les surfaces accessibles externes, en 11.3 et 11.8;
– révision de la procédure de l’essai de débordement, en 15.2;
– exigences supplémentaires relatives aux appareils commandés par des circuits électroniques programmables qui limitent le nombre d’éléments chauffants et de moteurs alimentés simultanément, en 22.108. La présente partie 2 doit être utilisée conjointement avec la dernière é

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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

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.

International Standard IEC 60335-2-7 has been prepared by IEC technical committee 61:

Safety of household and similar electrical appliances.
This eighth edition cancels and replaces the seventh edition published in 2008,

Amendment 1: 2011 and Amendment 2:2016. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
– requirements for steam generators in 3.1.9, 3.6.101, 19.101, 22.106, 22.107;
– additional definitions for washing machine types in 3.5.101,3.5.102, 3.5.103;

– additional requirements for appliances that are controlled by programmable electronic

circuits that limit the number of heating elements and motors from being energised at the

same time, Subclause 22.108.
The text of this International Standard is based on the following documents:
FDIS Report on voting
61/5798/FDIS 61/5839/RVD

Full information on the voting for the approval of this International Standard can be found in

the report on voting indicated in the above table.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

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.

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 fifth edition (2010) 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 washing machines.

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 2 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 3 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.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

NOTE 4 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.

INTRODUCTION

It has been assumed in the drafting of this International Standard that the execution of its

provisions is entrusted to appropriately qualified and experienced persons.

This standard recognizes the internationally accepted level of protection against hazards such

as electrical, mechanical, thermal, fire and radiation of appliances when operated as in

normal use taking into account the manufacturer's instructions. It also covers abnormal

situations that can be expected in practice and takes into account the way in which

electromagnetic phenomena can affect the safe operation of appliances.

This standard takes into account the requirements of IEC 60364 as far as possible so that

there is compatibility with the wiring rules when the appliance is connected to the supply

mains. However, national wiring rules may differ.

If an appliance within the scope of this standard also incorporates functions that are covered

by another part 2 of IEC 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.

When a part 2 standard does not include additional requirements to cover hazards dealt with

in Part 1, Part 1 applies.

NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is

not necessary to specify particular requirements for the appliance in question over and above the general

requirements.

This standard is a product family standard dealing with the safety of appliances and takes

precedence over horizontal and generic standards covering the same subject.

NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into

consideration when developing the general and particular requirements for the IEC 60335 series of standards. For

example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as

ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.

An appliance that complies with the text of this standard will not necessarily be considered to

comply with the safety principles of the standard if, when examined and tested, it is found to

have other features that impair the level of safety covered by these requirements.

An appliance employing materials or having forms of construction differing from those detailed

in the requirements of this standard may be examined and tested according to the intent of

the requirements and, if found to be substantially equivalent, may be considered to comply

with the standard.

HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
SAFETY –
Part 2-7: Particular requirements for washing machines
1 Scope
This clause of Part 1 is replaced by the following.

This International 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 appliances and 480 V for other 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.

NOTE 101 Guidance is given in Annex DD for requirements that can be used to ensure an acceptable level of

protection against electrical and thermal hazards for washing machines fitted with a power driven wringer.

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 102 Examples of such appliances are washing machines for communal use in blocks of flats or in

launderettes.

As far as is practicable, this standard deals with the common hazards presented by washing

machines that are encountered by all persons in and around the home. However, in general, 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.
NOTE 103 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.
NOTE 104 This standard does not apply to
– washing machines intended exclusively for industrial purposes (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);

– washing machines incorporating steam generating devices in which steam is produced at a pressure

exceeding 50 kPa.

This clause of Part 1 is applicable except as follows.
3.1 Definitions relating to physical characteristics
Replacement:
3.1.9
normal operation
operation of the appliance under the following conditions.

The appliance is filled with dry textile material having a mass equal to the maximum mass

stated in the instructions, and with the maximum quantity of water for which it is constructed.

However, if the power input or current is higher when only 50 % of the textile material is used,

the appliance is operated with this load instead if this gives more unfavourable conditions

than the full load during the test of Clause 11.

Note 101 to entry: For some appliances incorporating a programmer, using the 50 % reduced load may result in

automatic selection of a reduced wash programme.
The temperature of the water is
• 65 C ± 5 °C for appliances without heating elements;

• 15 °C ± 5 °C for appliances without heating elements and intended for connection to the

cold water supply only;
• 15 °C ± 5 °C for other appliances.

If the appliance does not incorporate a programmer, the water is heated to 90 °C ± 5 °C or as

high as the construction will allow if lower, before starting the first washing period.

The textile material consists of pre-washed double-hemmed cotton sheets having dimensions

2 2

approximately 700 mm × 700 mm and a specific mass between 140 g/m and 175 g/m in the

dry condition.

For impeller washing machines, if the textile material does not move properly during

operation,

• the quantity of textile material may be reduced until the maximum power input of the motor

is attained; or
• a textile material comprising pre-washed double-hemmed cotton sheets, having
dimensions of approximately 900 mm × 900 mm and a mass between 90 g/m and
110 g/m in the dry condition, may be used.

However, for impeller washing machines, in case of doubt, the test is carried out using the

reduced quantity of textile material.
