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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.

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.
Guidance documents concerning the application of the safety requirements for appliances can
be accessed via TC 61 supporting documents on the IEC website
https://www.iec.ch/tc61/supportingdocuments
This information is given for the convenience of users of this International Standard and does
not constitute a replacement for the normative text in this standard.
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 can 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 Horizontal publications, basic safety publications and group safety
publications 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. 1
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.
NOTE 3 Standards dealing with non-safety aspects of household appliances are:
– IEC standards published by TC 59 concerning methods of measuring performance;
– CISPR 11, CISPR 14-1 and relevant IEC 61000-3 series standards concerning electromagnetic emissions;
– CISPR 14-2 concerning electromagnetic immunity;
– IEC standards published by TC 111 concerning environmental matters. 2
1 Scope
This clause of Part 1 is replaced by the following.
This part of IEC 60335 deals with the safety of electric multifunctional shower cabinets and
electric separate multifunctional shower units for household and similar purposes, their
rated voltage being not more than 250 V for single-phase appliances and 480 V for other
appliances including DC supplied 3 appliances.
Appliances not intended for normal household use but which nevertheless may can be a source
of danger to the public, such as appliances intended to be used by laymen in hotels, fitness
centres and similar locations, are within the scope of this standard.
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 101 Attention is drawn to the fact that
– for appliances intended to be used in vehicles or on board ships or aircraft, additional
requirements may can be necessary;
– in many countries, additional requirements are specified by the national health authorities,
the national water supply authorities, the national authorities responsible for the protection
of labour and similar authorities;
– in many countries, mechanical strength, impact resistance and shattering properties of
shower enclosures can be covered by national regulations.
NOTE 102 If an appliance incorporates a part that is within the scope of IEC 60065, IEC 60598
series or IEC 60950 IEC 62368 series, the part is tested in accordance with the relevant
standard as far as reasonable.
NOTE 103 This standard does not apply to
– instantaneous water heaters used for showering (IEC 60335-2-35);
– shower-boost pumps (IEC 60335-2-41);
– appliances intended for medical 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).

19 Abnormal operation
This clause of Part 1 is applicable except as follows.
19.1 Addition:
Appliances having an air-heating function are also subjected to the test of 19.101.
19.2 Addition:
For appliances having a steam bath function, the test is carried out without water being
supplied.
Appliances incorporating a fan are also tested without the motor operating, air inlets and guards
not being covered.
19.101 Appliances having an air-heating function with a heater having an enclosure
substantially made of non-metallic material are operated as specified in Clause 11, except that
the motor is supplied separately at its working voltage. Thermal controls that operate during
the test of Clause 11 are short-circuited.
When steady conditions are established, the voltage applied to the motor is reduced until the
running speed of the motor is just sufficient to prevent a thermal cut-out from operating,
the voltage applied to the heating elements being maintained at the value used for 11.4.
To determine the minimum voltage without the thermal cut-out operating, the voltage of the
motor is reduced by 5 % and the motor is operated for 5 minutes. This procedure is repeated
until a thermal cut-out operates. The voltage is then increased by 5 %, this being considered
the voltage just sufficient to prevent a thermal cut-out from operating.
Under these conditions, the heater is again operated until steady conditions are established or
for 1 h, whichever is longer.
After this period, the airflow is further restricted to verify that a thermal cut-out operates.
NOTE The reduced voltage applied to the motor may be determined as follows. The voltage is reduced by 5 % and
the motor is operated under this condition for 5 min. This procedure is repeated until a thermal cut-out operates.
The voltage is then increased by 5 %, this being the reduced voltage to be used for the test. 10
20 Stability and mechanical hazards
This clause of Part 1 is applicable.
21 Mechanical strength
This clause of Part 1 is applicable.
22 Construction
This clause of Part 1 is applicable except as follows.
22.7 Addition:
Appliances having a steam bath function shall incorporate adequate safeguards against the risk
of excessive pressure.
If jets of steam or hot water are emitted through protective devices, the electrical insulation
shall not be affected or the user exposed to a hazard.
Compliance is checked by inspection and by the following test.
For pressurized boilers, the maximum pressure occurring during the test of Clause 11 with the
boiler filled but without steam emission is measured. All pressure-regulating devices that are
operated during the test are rendered inoperative and the pressure measured again. The
pressure shall not increase by more than 200 kPa.
Any pressure-limiting protective device is then rendered inoperative and the pressure in the
boiler is raised hydraulically to five times the pressure measured originally or twice the pressure
measured with the pressure-regulating device operating during the test of Clause 11 rendered
inoperative, whichever is higher. There shall be no leakage from the boiler.
22.33 Addition:
Parts such as switches and controls accessible to the user in the shower cabinet shall only be
supplied at safety extra-low voltage not exceeding 12 V.
Vapour is not considered to be a conductive liquid.
22.101 Appliances in which water is recirculated shall be constructed so that the quantity of
water remaining in the system after use shall not exceed 0,15 l.
Compliance is checked by measurement.
22.102 Appliances having provision for discharging steam shall be constructed so that the
steam outlets shall not direct the steam towards the user.
Compliance is checked by inspection.
22.103 For appliances that are controlled by programmable electronic circuits that limit the
number of heating elements and motors from being energized at the same time, simultaneous
activation of any combination of heating elements and motors shall not render the appliance
unsafe.
Compliance is checked as follows:
– the fault/error conditions specified in Table R.1 are applied and evaluated in accordance
with the relevant requirements of normative Annex R; or
– the appliance is operated under the conditions of Clause 11 while being supplied at rated

INTRODUCTION
Edition 6 of IEC 60335-1:2020 defines and introduces requirements for a detachable power
supply part of an appliance. In the document, 24.2 prohibits the use of a power supply in
a flexible cord.
QUESTION:
Does Subclause 24.2 prohibit the use of a detachable power supply part?
ANSWER
No, a "detachable power supply part" is a defined term and is not captured by the term
"power supply" as used in Subclause 24.2.
NOTE A detachable power supply part is captured by the defined term when the output of the power supply
part is detachable from the class III construction part of the appliance at:
– the power supply part, or
– the class III construction part of the appliance.
However, the supply cord (if any) does not have to be detachable from the detachable power supply part.

TC 61 interpretation sheet on: Mechanical shock and vibration testing on large metal-ion
batteries of IEC 60335-1:2020
INTRODUCTION
Currently the standard mentions:
B.24.1 The relevant standards for non-acid based electrolyte cells employed in batteries
are IEC 62133-1:2017 for nickel systems and IEC 62133-2:2017 for lithium systems.
NOTE The requirement for cells does not extend to the battery itself.
A battery that uses metal-ion chemistry shall additionally be subjected to the tests of
Subclauses 7.3.8.1 (vibration) and 7.3.8.2 (mechanical shock) of IEC 62133-2:2017.
When Annex B was written for the IEC 60335-1 edition 6, the batteries foreseen were for
portable applications and rather lightweight. The IEC 62133-2:2017 standard referred to is
applicable to portable lithium batteries only.

IEC 60335-1:2020-09/ISH2:2025-08(en-fr)

For non-portable and/or large batteries (mass > 12 kg), the tests of IEC 62133-2 for mechanical
shock and vibration are not suitable.
QUESTION:
What test sequence for mechanical shock and vibration can be followed for large batteries?
ANSWER:
For practical reasons, IEC 60335-1 should follow the same differentiation as the UN 38.3
transport test or IEC 62281 standard (Safety of primary and secondary lithium cells and
batteries during transport).
For larger batteries with a mass exceeding 12 kg, Subclauses 6.4.3 (Test T-3: Vibration) and
6.4.4 (Test T-4: Shock) of IEC 62281:2019, including AMD1:2021 and AMD2:2023, may be
applied.
NOTE 1 The tests are technically identical to Test T.3 and Test T.4 of the UN manual of tests and criteria, section
38.3 rev.8 (2023).
NOTE 2 In accordance with Table 5 of IEC 62281:2019, testing is carried out on the battery without packaging.

Part 2-105: Particular requirements for multifunctional shower cabinets

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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a) patent(s).
IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in respect
thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which may
be required to implement this document. However, implementers are cautioned that this may not represent the

INTRODUCTION to IEC 60335-1:2020
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.
Guidance documents concerning the application of the safety requirements for appliances can
be accessed via TC 61 supporting documents on the IEC website –
www.iec.ch/tc61/supportingdocuments
This information is given for the convenience of users of this International Standard and does
not constitute a replacement for the normative text in this standard.
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 the functions of an appliance are covered by different parts 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.
Throughout this publication, when "part 2" is mentioned, it refers to the relevant part of
IEC 60335.
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 publications, basic safety publications and group safety publications 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.
Individual countries may wish to consider the application of this standard, as far as is
reasonable, to appliances not mentioned in a part 2, and to appliances designed on new
principles. In this case, consideration should be given to defining normal operation, specifying
the classification of the appliance according to Clause 6 and specifying whether the appliance
is operated attended or unattended. Consideration should also be given to particular categories
of likely users and to related specific risks such as access to live parts, hot surfaces or

hazardous moving parts.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of this standard if, when examined and tested, it is found to
have other features which 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 this
standard.
NOTE 3 Standards dealing with non-safety aspects of household appliances are:
– IEC standards published by TC 59 concerning methods of measuring performance;
– CISPR 11, CISPR 14-1 and relevant IEC 61000-3 series standards concerning electromagnetic emissions;
– CISPR 14-2 concerning electromagnetic immunity;
– IEC standards published by TC 111 concerning environmental matters.

for the IEC 60335 series of 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.
NOTE 3 Standards dealing with non-safety aspects of household appliances are:
– IEC standards published by TC 59 concerning methods of measuring performance;
– CISPR 11, CISPR 14-1 and relevant IEC 61000-3 series standards concerning electromagnetic emissions;
– CISPR 14-2 concerning electromagnetic immunity;
– IEC standards published by TC 111 concerning environmental matters.

1 Scope
This part of IEC 60335 deals with the safety of electric multifunctional shower cabinets and
electric separate multifunctional shower units for household and similar purposes, their
rated voltage being not more than 250 V for single-phase appliances and 480 V for other
appliances including DC supplied appliances.
Appliances not intended for normal household use but which nevertheless can be a source of
danger to the public, such as appliances intended to be used by laymen in hotels, fitness
centres and similar locations, are within the scope of this standard.
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.
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 water supply authorities, the national authorities responsible for the protection
of labour and similar authorities;
– in many countries, mechanical strength, impact resistance and shattering properties of
shower enclosures can be covered by national regulations.
If an appliance incorporates a part that is within the scope of IEC 60598 series or IEC 62368
series, the part is tested in accordance with the relevant standard as far as reasonable.
This standard does not apply to
– instantaneous water heaters used for showering (IEC 60335-2-35);
– shower-boost pumps (IEC 60335-2-41);
– appliances intended for medical 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).

AVANT-PROPOS
1) La Commission Électrotechnique Internationale (IEC) est une organisation mondiale de normalisation composée
de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l'IEC). L'IEC a pour objet de
favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines de
l'électricité et de l'électronique. À cet effet, l'IEC – entre autres activités – publie des Normes internationales,
des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au public (PAS) et des
Guides (ci-après dénommés "Publication(s) de l'IEC"). Leur élaboration est confiée à des comités d'études, aux
travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les organisations
internationales, gouvernementales et non gouvernementales, en liaison avec l'IEC, participent également aux
travaux. L'IEC collabore étroitement avec l'Organisation Internationale de Normalisation (ISO), selon des
conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de l'IEC concernant les questions techniques représentent, dans la mesure du
possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l'IEC intéressés
sont représentés dans chaque comité d'études.
3) Les Publications de l'IEC se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de l'IEC. Tous les efforts raisonnables sont entrepris afin que l'IEC
s'assure de l'exactitude du contenu technique de ses publications; l'IEC ne peut pas être tenue responsable de
l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de l'IEC s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de l'IEC dans leurs publications nationales
et régionales. Toutes divergences entre toutes Publications de l'IEC et toutes publications nationales ou
régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) L'IEC elle-même ne fournit aucune attestation de conformité. Des organismes de certification indépendants
fournissent des services d'évaluation de conformité et, dans certains secteurs, accèdent aux marques de
conformité de l'IEC. L'IEC n'est responsable d'aucun des services effectués par les organismes de certification
indépendants.
6) Tous les utilisateurs doivent s'assurer qu'ils sont en possession de la dernière édition de cette publication.
7) Aucune responsabilité ne doit être imputée à l'IEC, à ses administrateurs, employés, auxiliaires ou mandataires,
y compris ses experts particuliers et les membres de ses comités d'études et des Comités nationaux de l'IEC,
pour tout préjudice causé en cas de dommages corporels et matériels, ou de tout autre dommage de quelque
nature que ce soit, directe ou indirecte, ou pour supporter les coûts (y compris les frais de justice) et les dépenses
découlant de la publication ou de l'utilisation de cette Publication de l'IEC ou de toute autre Publication de l'IEC,
ou au crédit qui lui est accordé.
8) L'attention est attirée sur les références normatives citées dans cette publication. L'utilisation de publications
référencées est obligatoire pour une application correcte de la présente publication.
9) L'IEC attire l'attention sur le fait que la mise en application du présent document peut entraîner l'utilisation d'un
ou de plusieurs brevets. L'IEC ne prend pas position quant à la preuve, à la validité et à l'applicabilité de tout
droit de brevet revendiqué à cet égard. À la date de publication du présent document, l'IEC n'avait pas reçu
notification qu'un ou plusieurs brevets pouvaient être nécessaires à sa mise en application. Toutefois, il y a lieu
d'avertir les responsables de la mise en application du présent document que des informations plus récentes
sont susceptibles de figurer dans la base de données de brevets, disponible à l'adresse https://patents.iec.ch.
L'IEC ne saurait être tenue pour responsable de ne pas avoir identifié de tels droits de brevets.
L'IEC 60335-2-105 a été établie par le comité d'études 61 de l'IEC: Sécurité des appareils
électrodomestiques et analogues. Il s'agit d'une Norme internationale.
Cette troisième édition annule et remplace la deuxième édition parue en 2016 et
l'Amendement 1:2019. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition
précédente:
a) le texte a été aligné sur l'IEC 60335-1:2020;
b) certaines notes ont été converties en texte normatif (Article 1);
c) les exigences pour la température de surface ont été mises à jour (11.8, Tableau 101).

Ce document a été rédigé selon les Directives ISO/IEC, Partie 2, il a été développé selon les
Directives ISO/IEC, Partie 1 et les Directives ISO/IEC, Supplément IEC, disponibles sous
www.iec.ch/members_experts/refdocs. Les principaux types de documents développés par
l'IEC sont décrits plus en détail sous www.iec.ch/publications.
La présente partie 2 doit être utilisée conjointement avec la dernière édition de l'IEC 60335-1
et ses amendements sauf si cette édition l'exclut. Dans ce cas, la dernière édition qui n'exclut
pas la présente partie 2 est utilisée. Elle a été établie sur la base de la sixième édition (2020)
de cette norme.
NOTE 1 L'expression "la Partie 1" utilisée dans la présente norme fait référence à l'IEC 60335-1.
La présente partie 2 complète ou modifie les articles correspondants de l'IEC 60335-1, de façon
à transformer cette publication en norme IEC: Exigences particulières pour les cabines de
douche multifonctions
Lorsqu'un paragraphe particulier de la Partie 1 n'est pas mentionné dans cette partie 2, ce
paragraphe s'applique pour autant que cela soit raisonnable. Lorsque la présente norme
mentionne "addition", "modification" ou "remplacement", le texte correspondant de la Partie 1
doit être adapté en conséquence.
NOTE 2 Le système de numérotation suivant est utilisé:
– les paragraphes, tableaux et figures qui s'ajoutent à ceux de la Partie 1 sont numérotés à partir de 101;
– à l'exception de celles qui sont dans un nouveau paragraphe ou de celles qui concernent des notes de la Partie 1,
les notes sont numérotées à partir de 101, y compris celles des articles ou paragraphes qui sont remplacés;
– les annexes qui sont ajoutées sont désignées AA, BB, etc.

électrodomestiques et analogues - Sécurité, se trouve sur le site web de l'IEC.
Le comité a décidé que le contenu du présent document ne sera pas modifié avant la date de
stabilité indiquée sur le site web de l'IEC sous http://webstore.iec.ch dans les données relatives
au document recherché. À cette date, le document sera
– reconduit,
– supprimé ou
– révisé.
INTRODUCTION
Il a été admis par hypothèse, en établissant la présente Norme internationale, que l'exécution
de ses dispositions était confiée à des personnes expérimentées et ayant une qualification
appropriée.
Les documents de recommandations concernant l'application des exigences de sécurité pour
les appareils peuvent être consultés dans les documents de support du CE 61, accessibles sur
le site web de l'IEC à l'adresse:
https://www.iec.ch/tc61/supportingdocuments
Cette information est donnée à l'intention des utilisateurs de la présente Norme internationale
et ne constitue nullement un remplacement du texte normatif de la présente norme.
La présente norme reconnaît le niveau de protection internationalement accepté contre les
dangers électriques, mécaniques, thermiques, liés au feu et au rayonnement des appareils,
lorsqu'ils fonctionnent comme en usage normal en tenant compte des instructions du fabricant.
Elle couvre également les situations anormales auxquelles on peut s'attendre dans la pratique
et elle tient compte de la façon dont les phénomènes électromagnétiques peuvent altérer le
fonctionnement sûr des appareils.
Cette norme tient compte autant que possible des exigences de l'IEC 60364, de façon à rester
compatible avec les règles d'installation quand l'appareil est raccordé au réseau d'alimentation.
Cependant, des règles nationales d'installation peuvent être différentes.
Si un appareil relevant du domaine d'application de la présente norme comporte également des
fonctions couvertes par une autre partie 2 de l'IEC 60335, la partie 2 correspondante est
appliquée à chaque fonction séparément, dans la limite du raisonnable. Si cela s'applique,
l'influence d'une fonction sur les autres fonctions est prise en compte.
Lorsqu'une partie 2 ne comporte pas d'exigences complémentaires pour couvrir les risques
traités dans la Partie 1, la Partie 1 s'applique.
NOTE 1 Cela signifie que les comités d'études responsables pour les parties 2 ont déterminé qu'il n'était pas
nécessaire de spécifier des exigences particulières pour l'appareil en question en plus des exigences générales.
Cette norme est une norme de famille de produits traitant de la sécurité d'appareils et prévaut
sur les normes horizontales et génériques couvrant le même sujet.
NOTE 2 Les publications horizontales, les publications fondamentales de sécurité et les publications groupées de
sécurité couvrant un danger ne s'appliquent pas, parce qu'elles ont été prises en considération lorsque les exigences
générales et particulières ont été étudiées pour la série de normes IEC 60335.
Un appareil conforme au texte de la présente norme ne sera pas nécessairement jugé conforme
aux principes de sécurité de la norme si, lorsqu'il est examiné et soumis aux essais, il apparaît
qu'il présente d'autres caractéristiques qui compromettent le niveau de sécurité visé par ces
exigences.
Un appareil utilisant des matériaux ou présentant des modes de construction différents de ceux
décrits dans les exigences de la présente norme peut être examiné et soumis aux essais en
fonction de l'objectif poursuivi par ces exigences et, s'il est jugé pratiquement équivalent, il peut
être estimé conforme aux principes de sécurité de la présente norme.
NOTE 3 Les normes traitant des aspects non relatifs à la sécurité des appareils électrodomestiques sont:
– les normes IEC publiées par le comité d'études 59 concernant les méthodes de mesure d'aptitude à la fonction;
– les normes CISPR 11 et CISPR 14-1, ainsi que les normes applicables de la série IEC 61000-3 concernant les
émissions électromagnétiques;
– la norme CISPR 14-2 concernant l'immunité électromagnétique;
– les normes IEC publiées par le comité d'études 111 concernant l'environnement.

Part 2-105: Particular requirements for multifunctional shower cabinets

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

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.
Guidance documents concerning the application of the safety requirements for appliances can
be accessed via TC 61 supporting documents on the IEC website
https://www.iec.ch/tc61/supportingdocuments
This information is given for the convenience of users of this International Standard and does
not constitute a replacement for the normative text in this standard.
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 can 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 publications, basic safety publications and group safety publications 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.
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.
NOTE 3 Standards dealing with non-safety aspects of household appliances are:
– IEC standards published by TC 59 concerning methods of measuring performance;
– CISPR 11, CISPR 14-1 and relevant IEC 61000-3 series standards concerning electromagnetic emissions;
– CISPR 14-2 concerning electromagnetic immunity;
– IEC standards published by TC 111 concerning environmental matters.

1 Scope
This clause of Part 1 is replaced by the following.
This part of IEC 60335 deals with the safety of electric multifunctional shower cabinets and
electric separate multifunctional shower units for household and similar purposes, their
rated voltage being not more than 250 V for single-phase appliances and 480 V for other
appliances including DC supplied appliances.
Appliances not intended for normal household use but which nevertheless can be a source of
danger to the public, such as appliances intended to be used by laymen in hotels, fitness
centres and similar locations, are within the scope of this standard.
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.
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 water supply authorities, the national authorities responsible for the protection
of labour and similar authorities;
– in many countries, mechanical strength, impact resistance and shattering properties of
shower enclosures can be covered by national regulations.
If an appliance incorporates a part that is within the scope of IEC 60598 series or IEC 62368
series, the part is tested in accordance with the relevant standard as far as reasonable.
This standard does not apply to
– instantaneous water heaters used for showering (IEC 60335-2-35);
– shower-boost pumps (IEC 60335-2-41);
– appliances intended for medical 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).

19 Abnormal operation
This clause of Part 1 is applicable except as follows.
19.1 Addition:
Appliances having an air-heating function are also subjected to the test of 19.101.
19.2 Addition:
For appliances having a steam bath function, the test is carried out without water being
supplied.
Appliances incorporating a fan are also tested without the motor operating, air inlets and guards
not being covered.
19.101 Appliances having an air-heating function with a heater having an enclosure
substantially made of non-metallic material are operated as specified in Clause 11, except that
the motor is supplied separately at its working voltage. Thermal controls that operate during
the test of Clause 11 are short-circuited.
When steady conditions are established, the voltage applied to the motor is reduced until the
running speed of the motor is just sufficient to prevent a thermal cut-out from operating,
the voltage applied to the heating elements being maintained at the value used for 11.4.
To determine the minimum voltage without the thermal cut-out operating, the voltage of the
motor is reduced by 5 % and the motor is operated for 5 minutes. This procedure is repeated
until a thermal cut-out operates. The voltage is then increased by 5 %, this being considered
the voltage just sufficient to prevent a thermal cut-out from operating.
Under these conditions, the heater is again operated until steady conditions are established or
for 1 h, whichever is longer.
After this period, the airflow is further restricted to verify that a thermal cut-out operates.
20 Stability and mechanical hazards
This clause of Part 1 is applicable.
21 Mechanical strength
This clause of Part 1 is applicable.
22 Construction
This clause of Part 1 is applicable except as follows.
22.7 Addition:

If jets of steam or hot water are emitted through protective devices, the electrical insulation
shall not be affected or the user exposed to a hazard.
Compliance is checked by inspection and by the following test.
For pressurized boilers, the maximum pressure occurring during the test of Clause 11 with the
boiler filled but without steam emission is measured. All pressure-regulating devices that are
operated during the test are rendered inoperative and the pressure measured again. The
pressure shall not increase by more than 200 kPa.
Any pressure-limiting protective device is then rendered inoperative and the pressure in the
boiler is raised hydraulically to five times the pressure measured originally or twice the pressure
measured with the pressure-regulating device operating during the test of Clause 11 rendered
inoperative, whichever is higher. There shall be no leakage from the boiler.
22.33 Addition:
Parts such as switches and controls accessible to the user in the shower cabinet shall only be
supplied at safety extra-low voltage not exceeding 12 V.
Vapour is not considered to be a conductive liquid.
22.101 Appliances in which water is recirculated shall be constructed so that the quantity of
water remaining in the system after use shall not exceed 0,15 l.

22.102 Appliances having provision for discharging steam shall be constructed so that the
steam outlets shall not direct the steam towards the user.
Compliance is checked by inspection.
22.103 For appliances that are controlled by programmable electronic circuits that limit the
number of heating elements and motors from being energized at the same time, simultaneous
activation of any combination of heating elements and motors shall not render the appliance
unsafe.
Compliance is checked as follows:
– the fault/error conditions specified in Table R.1 are applied and evaluated in accordance
with the relevant requirements of normative Annex R; or
– the appliance is operated under the conditions of Clause 11 while being supplied at rated
