IEC 60335-2-2:2019 est disponible sous forme de IEC 60335-2-2:2019 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 60335-2-2:2019 traite de la sécurité des aspirateurs et des appareils de nettoyage à aspiration d'eau électriques pour usages domestiques et analogues, y compris les aspirateurs pour les soins des animaux, dont la tension assignée n'est pas supérieure à 250 V. Elle s'applique également aux aspirateurs à unité centrale d'aspiration et aux aspirateurs automatiques alimentés par batteries. La présente norme s'applique aussi aux têtes de nettoyage motorisées et aux flexibles conducteurs associés à un aspirateur donné. Les appareils alimentés par batteries et autres appareils alimentés en courant continu relèvent du domaine d'application de la présente norme. Les appareils à double alimentation, fonctionnant sur secteur ou sur batterie, sont vus comme des appareils alimentés par batteries lorsqu'ils fonctionnent sur batterie. 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 que les appareils destinés à être utilisés par des usagers non avertis pour l'entretien ménager courant normal dans des magasins et autres locaux, relèvent du domaine d'application de la présente norme. Les appareils destinés à être utilisés pour l'entretien ménager courant dans les hôtels, bureaux, écoles, hôpitaux et locaux analogues constituent des exemples de tels appareils. Dans la mesure du possible, la présente norme traite des dangers courants présentés par les appareils, 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 connaissances 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 appareils destinés à être utilisés 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 autorités sanitaires nationales, les organismes nationaux en charge de la protection des travailleurs, les organismes nationaux responsables de l'alimentation en eau et des organismes analogues. La présente norme ne s'applique pas: – aux appareils prévus exclusivement pour des usages industriels; – 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 aspirateurs fonctionnant en présence d'eau ou à sec, y compris les brosses motorisées, à usage commercial (IEC 60335-2-69). Cette septième édition annule et remplace la sixième édition parue en 2009, l'Amendement 1:2012 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: – certaines exigences applicab

Part 2-2: Particular requirements for vacuum cleaners
and water-suction cleaning appliances

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 60335-2-2 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 2009, Amendment
1:2012 and Amendment 2:2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– some requirements for appliances for animal grooming have been modified (6.1, 25.7)
– the note in 7.101 has been deleted;
– converted some notes to normative text (7.102, 10.1, 11.3, 13.1, 15.2, 15.101, 19.101,
20.1, 20.2, 21.103, 21.105, 22.32, 25.23);

– clarification that the test of 19.7 is applicable to vacuum cleaners with a motorized brush
or similar device;
– modified Annex R for alignment with 22.201 of Annex B;
– modified Annex S in accordance with IEC 60335-2-2:2009/ISH1:2016;
– requirements for mechanical strength of handles have been added (21.106).
The text of this International Standard is based on the following documents:
FDIS Report on voting
61/5790/FDIS 61/5807/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

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 2-2: Particular requirements for vacuum cleaners
and water-suction cleaning appliances



1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electric vacuum cleaners and
water-suction cleaning appliances for household and similar purposes, including vacuum
cleaners for animal grooming, their rated voltage being not more than 250 V. It also applies
to centrally-sited vacuum cleaners and automatic battery-operated cleaners.
This standard also applies to motorized cleaning heads and current-carrying hoses
associated with a particular vacuum cleaner.
Battery-operated appliances and other DC supplied appliances are within the scope of this
standard. Dual supply appliances, either mains-supplied or battery-operated, are regarded as
battery-operated appliances when operated in the battery mode.
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 and other
premises for normal housekeeping purposes, are within the scope of this standard.
NOTE 101 Examples of such appliances are appliances intended to be used for normal housekeeping purposes in
hotels, offices, schools, hospitals and similar premises.
As far as is practicable, this standard deals with the common hazards presented by
appliances 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 102 Attention is drawn to the fact that
– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can 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 103 This standard does not apply to
– appliances intended exclusively for industrial purposes;
– 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);
– wet and dry vacuum cleaners, including power brush, for commercial use (IEC 60335-2-69).

If the appliance is marked with a rated voltage range, it is supplied at the mean value of the
range if the difference between the limits of the range does not exceed 10 % of the mean
value. If the difference exceeds 10 %, the supply voltage is the upper value of the range.
The measurements are made with the appliance fitted with a clean dust bag and filter, any
water collection container being empty. If the appliance is intended to be u
