Part 2-23: Particular requirements for appliances for skin or hair care and
similar appliances 1
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.
This commented version (CMV) of the official standard IEC 60335-2-23:2026 edition 7.0 allows
the user to identify the changes made to the previous IEC 60335-2-23:2016+AMD1:2019 CSV
edition 6.1. Furthermore, comments from IEC TC 61 experts are provided to explain the reasons
of the most relevant changes, or to clarify any part of the content.
A vertical bar appears in the margin wherever a change has been made. Additions are in green
text, deletions are in strikethrough red text. Experts' comments are identified by a blue-
background number. Mouse over a number to display a pop-up note with the comment.
This publication contains the CMV and the official standard. The full list of comments is available
at the end of the CMV.
IEC 60335-2-23 has been prepared by IEC technical committee 61: Safety of household and
similar electrical appliances. It is an International Standard.
This seventh edition cancels and replaces the sixth edition published in 2016 and
Amendment 1:2019. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) alignment with IEC 60335-1:2020;
b) conversion of some notes to normative text (Clause 1, 11.101, 20.1);
c) change in standard title and relocation of skin care appliances, such as facial saunas and
foot care appliances, to IEC 60335-2-115 (Clause 1, 3.1.9, 3.5.103, 6.1, 7.12, 8.1.4, 11.8,
15.2, 21.1);
d) clarification of testing of appliances with PTC heating elements (10.1, 10.2);
e) clarification of the application of test probe 18 for appliances for use in hairdressing salons
(8.1.1, 20.2, B.22.3, B.22.4);
f) addition of accessible surface temperature limits including marking of hot surfaces (7.1, 7.6,
7.12, 7.14, 7.15, 11.3, 11.8);
g) clarification of placement of the appliance in the test corner (19.2);
h) addition of moisture resistance and strength tests for detachable power supply parts (6.2,

The text of this International Standard is based on the following documents:
Draft Report on voting
61/7533/FDIS 61/7542/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/publications.
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its
amendments unless that edition precludes it; in that case, the latest edition that does not
preclude it is used. It was established on the basis of the sixth edition (2020) 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: Particular requirements for hair care and similar
appliances.
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.
NOTE 4 The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations can 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.
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 this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
– reconfirmed,
– withdrawn, or
– revised.
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.
NOTE 1 For example, if appliances within the scope of this Part 2 include an ion generator, then IEC 60335-2-65
is applicable as far as is reasonable.
When a part 2 standard does not include additional requirements to cover hazards dealt with in
Part 1, Part 1 applies.
NOTE 2 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 3 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. 2
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. 3

1 Scope
This clause of Part 1 is replaced by the following.
This part of IEC 60335 deals with the safety of electric appliances for the care of skin or the
hair of persons or animals and similar appliances 4, intended for household and similar
purposes, their rated voltage being not more than 250 V including direct current (DC) supplied
appliances and battery-operated appliances. 5
NOTE 101 Examples of appliances that are within the scope of this standard are
– curling combs;
– curling irons;
– curling rollers with separate heaters; 6
– facial saunas; 7
– hairdryers;
– hair straighteners;
– hand dryers;
– heaters for detachable curlers;
– water filled foot care appliances without massage function; 8
– permanent-wave appliances.
NOTE 102 Appliances covered by this standard may can incorporate steam-producing or spray-
producing devices.
NOTE 101 Hand dryers can have a feature to redirect the air so that it can be used to dry the face or hair.
Appliances not intended for normal household use but that nevertheless may can 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 103 Examples are appliances for use in hairdressing salons.
This standard deals with the reasonably foreseeable hazards presented by appliances that are
encountered by all persons. 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 104 Attention is drawn to the fact that
– it is recognized that persons having very extensive and complex disabilities can have needs
beyond the level addressed in this standard.
– 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 authorities responsible for the protection of labour and similar authorities.
NOTE 105 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);
– shavers, hair clippers and similar appliances (IEC 60335-2-8);
– blankets, pads, clothing and similar flexible heating appliances (IEC 60335-2-17);
– appliances for skin exposure to optical radiation (IEC 60335-2-27);
– sauna heating appliances (IEC 60335-2-53);
– cosmetic and beauty care appliances incorporating lasers and intense light sources
(IEC 60335-2-113);
– water filled foot massagers (IEC 60335-2-32);
– appliances intended for medical purposes (IEC 60601) skin care (IEC 60335-2-115).
NOTE 106 A water filled foot care appliance with water jets is not considered to have a massage function. 9

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.

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.

The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/publications.
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its
amendments unless that edition precludes it; in that case, the latest edition that does not
preclude it is used. It was established on the basis of the sixth edition (2020) 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: Particular requirements for hair care and similar
appliances.
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

stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
– reconfirmed,
– withdrawn, or
– revised.
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.

INTRODUCTION to IEC 60335-2-23:2026
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 part of IEC 60335 deals with the safety of electric appliances for the care of the hair of
persons or animals and similar appliances, intended for household and similar purposes, their
rated voltage being not more than 250 V including direct current (DC) supplied appliances and
battery-operated appliances.
Examples of appliances that are within the scope of this standard are
– curling combs;
– curling irons;
– hairdryers;
– hair straighteners;
– hand dryers;
– heaters for detachable curlers;
– permanent-wave appliances.
Appliances covered by this standard can incorporate steam-producing or spray-producing
devices.
NOTE 101 Hand dryers can have a feature to redirect the air so that it can be used to dry the face or hair.
Appliances not intended for normal household use but that nevertheless can 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 are appliances for use
in hairdressing salons.
This standard deals with the reasonably foreseeable hazards presented by appliances that are
encountered by all persons. 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
– it is recognized that persons having very extensive and complex disabilities can have needs
beyond the level addressed in this standard.
– 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 and similar authorities.
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);
– shavers, hair clippers and similar appliances (IEC 60335-2-8);
– cosmetic and beauty care appliances incorporating lasers and intense light sources
(IEC 60335-2-113);
– appliances intended for skin care (IEC 60335-2-115).

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 60335-2-23 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 septième édition annule et remplace la sixième 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, 11.101, 20.1);
c) le titre de la norme a été modifié et les appareils destinés aux soins de la peau, tels que les
appareils de sauna facial et les appareils destinés aux soins des pieds, ont été déplacés
vers l'IEC 60335-2-115 (Article 1, 3.1.9, 3.5.103, 6.1, 7.12, 8.1.4, 11.8, 15.2, 21.1);

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
risques 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 qui peuvent être attendues dans la pratique et
elle tient compte de la façon dont les phénomènes électromagnétiques peuvent altérer le
fonctionnement sûr des appareils.
La présente 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 d'installation nationales 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 dangers
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.
La présente norme est une norme de famille de produits traitant de la sécurité d'appareils et a
préséance 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.

1 Domaine d'application
L'article de la Partie 1 est remplacé par le texte suivant.
La présente partie de l'IEC 60335 traite de la sécurité des appareils électriques pour les soins
des cheveux des personnes ou des poils des animaux et appareils analogues, destinés aux
usages domestiques et analogues, dont la tension assignée est inférieure ou égale à 250 V,
y compris les appareils alimentés en courant continu et les appareils alimentés par batteries.
La liste suivante répertorie les exemples d'appareils qui relèvent du domaine d'application de
la présente norme:
– les peignes à friser;
– les fers à friser;
– les sèche-cheveux;
– les lisseurs;
– les sèche-mains;
– les dispositifs de chauffage pour parties frisantes amovibles;
– les appareils à permanente.
Les appareils couverts par la présente norme peuvent intégrer des dispositifs à production de
vapeur ou à aspersion.
NOTE 101 Les sèche-mains peuvent disposer d'une fonctionnalité permettant de rediriger l'air de manière à pouvoir
être utilisés pour sécher le visage ou les cheveux.
Les appareils non 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 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 appareils utilisés dans les
salons de coiffure constituent des exemples de ce type d'appareils.
La présente norme traite des dangers raisonnablement prévisibles que présentent les appareils
pour toutes les personnes. Cependant, elle ne tient en général pas compte
– 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;
– des enfants qui jouent avec l'appareil.
L'attention est attirée sur le fait que
– il est avéré que les personnes qui présentent des handicaps très importants et complexes
peuvent avoir des besoins qui dépassent le cadre de la présente norme;
– 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 organismes
nationaux de la santé, par les organismes nationaux responsables de la protection des
travailleurs et par des organismes similaires.
La présente norme ne s'applique pas
– aux appareils prévus exclusivement pour des usages industriels;
– aux appareils destinés à être utilisés dans des locaux qui présentent des conditions
particulières, telles que la présence d'une atmosphère corrosive ou explosive (poussière,
vapeur ou gaz);
– aux rasoirs, tondeuses et appareils analogues (IEC 60335-2-8);
– aux appareils destinés aux soins cosmétiques et esthétiques comportant des lasers et des
sources de lumière de forte intensité (IEC 60335-2-113);
– aux appareils destinés aux soins de la peau (IEC 60335-2-115).

Part 2-23: Particular requirements for hair care and similar 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) 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.
IEC 60335-2-23 has been prepared by IEC technical committee 61: Safety of household and
similar electrical appliances. It is an International Standard.
This seventh edition cancels and replaces the sixth edition published in 2016 and
Amendment 1:2019. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) alignment with IEC 60335-1:2020;
b) conversion of some notes to normative text (Clause 1, 11.101, 20.1);
c) change in standard title and relocation of skin care appliances, such as facial saunas and
foot care appliances, to IEC 60335-2-115 (Clause 1, 3.1.9, 3.5.103, 6.1, 7.12, 8.1.4, 11.8,
15.2, 21.1);
d) clarification of testing of appliances with PTC heating elements (10.1, 10.2);
e) clarification of the application of test probe 18 for appliances for use in hairdressing salons
(8.1.1, 20.2, B.22.3, B.22.4);
f) addition of accessible surface temperature limits including marking of hot surfaces (7.1, 7.6,
7.12, 7.14, 7.15, 11.3, 11.8);
g) clarification of placement of the appliance in the test corner (19.2);
h) addition of moisture resistance and strength tests for detachable power supply parts (6.2,
21.102, 21.103, 24.2).
The text of this International Standard is based on the following documents:
Draft Report on voting
61/7533/FDIS 61/7542/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/publications.
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its
amendments unless that edition precludes it; in that case, the latest edition that does not
preclude it is used. It was established on the basis of the sixth edition (2020) 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: Particular requirements for hair care and similar
appliances.
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.
NOTE 4 The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations can 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

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 appliances for the care of the hair of
persons or animals and similar appliances, intended for household and similar purposes, their
rated voltage being not more than 250 V including direct current (DC) supplied appliances and
battery-operated appliances.
Examples of appliances that are within the scope of this standard are
– curling combs;
– curling irons;
– hairdryers;
– hair straighteners;
– hand dryers;
– heaters for detachable curlers;
– permanent-wave appliances.
Appliances covered by this standard can incorporate steam-producing or spray-producing
devices.
NOTE 101 Hand dryers can have a feature to redirect the air so that it can be used to dry the face or hair.
Appliances not intended for normal household use but that nevertheless can 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 are appliances for use
in hairdressing salons.
This standard deals with the reasonably foreseeable hazards presented by appliances that are
encountered by all persons. 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
– it is recognized that persons having very extensive and complex disabilities can have needs
beyond the level addressed in this standard.
– 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 and similar authorities.
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);
– shavers, hair clippers and similar appliances (IEC 60335-2-8);
– cosmetic and beauty care appliances incorporating lasers and intense light sources
(IEC 60335-2-113);
– appliances intended for skin care (IEC 60335-2-115).
