Household and similar electrical appliances - Safety - Part 2-23: Particular requirements for appliances for skin or hair care
IEC 60335-2-23:2016 deals with the safety of electric appliances for the care of skin or hair of persons or animals and intended for household and similar purposes, their rated voltage being not more than 250 V. Examples of appliances that are within the scope of this standard are:
- curling combs;
- curling irons;
- curling rollers with separate heaters;
- facial saunas;
- hairdryers;
- hair straighteners;
- hand dryers;
- heaters for detachable curlers and permanent-wave appliances. Appliances covered by this standard may incorporate steam-producing or spray-producing devices. Appliances not intended for normal household use but that nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard. 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. 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;
- blankets, pads, clothing and similar flexible heating appliances;
- appliances for skin exposure to optical radiation;
- sauna heating appliances;
- cosmetic and beauty care appliances incorporating lasers and intense light sources or appliances intended for medical purposes. This sixth edition cancels and replaces the fifth edition published in 2003 including its Amendment 1 (2008) and its Amendment 2 (2012). This edition constitutes a technical revision. The principal changes in this edition as compared with the fourth edition of IEC 60335-2-23 are as follows (minor changes are not listed):
- added hair straighteners to the list of examples covered by the standard;
- modified 7.12 to apply to appliances, and not just to hairdryers;
- added new instructions in 7.12 for hair straighteners and curling irons;
- exempted fixed hairdryers and fixed hand dryers from alternative format of instructions;
- excluded detachable curler surfaces from temperature rise requirement in Subclause 11.8;
- clarified in Subclause 19.7 that the appliance shall not emit flame after the test;
- clarified method of test and compliance criteria in Subclause 21.101;
- added requirement in 22.13 to delineate handles on curling irons and hair straighteners;
- in 22.103, added a requirement for protection against hair being pulled into hair dryer intake;
- revised Subclause 24.101 to indicate that protective devices shall not be self-resetting and reviewed and converted notes to normative text in Subclauses 19.7, 22.32, and 25.14. It was established on the basis of the fifth edition (2010) of that standard. The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months or later than 36 months from the date of its publication. Key words: Skin Care, Hair Care, Curling, Dryers
This publication is to be read in conjunction with IEC 60335-1:2010.

Part 2-23: Particular requirements for appliances for skin or hair care
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition. A vertical bar appears in the margin wherever a change
has been made. Additions are in green text, deletions are in strikethrough red text.

INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its
provisions is entrusted to appropriately qualified and experienced persons.
This standard recognizes the internationally accepted level of protection against hazards such
as electrical, mechanical, thermal, fire and radiation of appliances when operated as in
normal use taking into account the manufacturer's instructions. It also covers abnormal
situations that can be expected in practice and takes into account the way in which
electromagnetic phenomena can affect the safe operation of appliances.
This standard takes into account the requirements of IEC 60364 as far as possible so that
there is compatibility with the wiring rules when the appliance is connected to the supply
mains. However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
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 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 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of
the requirements and, if found to be substantially equivalent, may be considered to comply
with the standard.

Part 2-23: Particular requirements for appliances for skin or hair care
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 hair
of persons or animals and intended for household and similar purposes, their rated voltage
being not more than 250 V.
NOTE 101 Examples of appliances that are within the scope of this standard are
– curling combs;
– curling irons;
– curling rollers with separate heaters;
– facial saunas;
– hairdryers;
– hair straighteners;
– hand dryers;
– heaters with for detachable curlers;
– permanent-wave appliances.
NOTE 102 Appliances covered by this standard may incorporate steam-producing or spray-producing devices.
Appliances not intended for normal household use but that nevertheless may be a source of

– the use of appliances by young persons (including children) or infirm persons 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 by young children.
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 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);

19.10 Addition:
The test is carried out with the heating elements disconnected or switched off.
19.101 Hairdryers are operated as specified in Clause 11 except that the motor is supplied
separately at its working voltage until steady conditions are established. The voltage at the
terminals of the motor is then reduced until the running speed of the motor is just sufficient to
prevent the thermal cut-out from operating, the power input to the heating element being
maintained at 1,15 times rated power input.
NOTE It may be necessary to compensate for the effect on the heating element of supplying the motor separately.
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.
The reduced voltage applied to the motor is 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.
Under these conditions, the hairdryer is again operated until steady conditions are
established.
The hairdryer shall not emit flames or molten metal, temperature rises shall not exceed the
values specified in Table 9 and the other criteria of 19.13 do not apply.
The voltage is decreased at
– 1 V per minute, for motors having a working voltage not exceeding 30 V;
– 5 V per minute, for motors having a working voltage exceeding 30 V.
The appliance is then operated until steady conditions are established.
19.102 Portable hair dryers are operated under normal operation at 1,15 times rated
power input.
The test is carried out for 30 min.
The test is repeated with the airflow directed horizontally.
NOTE The most unfavourable conditions are usually obtained by positioning the polyethylene sheet so that the
thermal cut-out is prevented from operating.
20 Stability and mechanical hazards
This clause of Part 1 is applicable.

horizontal surface positioned 700 mm above a rigidly supported hardwood board and operated
while supplied at rated voltage.
It is pulled from the surface by its supply cord and allowed to drop freely. The test is carried
out five times, the appliance being placed on the horizontal surface in different positions likely
to occur.
The appliance shall not be damaged to such an extent that compliance with this standard is
impaired. In particular, the appliance shall not emit flames or molten material and the
requirements of Clauses 8 and 29 shall be fulfilled.

Part 2-23: Particular requirements for appliances for skin or hair care
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
This part of International Standard IEC 60335 has been prepared by IEC technical committee
61: Safety of household and similar electrical appliances.
This sixth edition cancels and replaces the fifth edition published in 2003 including its
Amendment 1 (2008) and its Amendment 2 (2012). This edition constitutes a technical
revision.
The principal changes in this edition as compared with the fourth edition of IEC 60335-2-23
are as follows (minor changes are not listed):
• added hair straighteners to the list of examples covered by the standard;
• modified 7.12 to apply to appliances, and not just to hairdryers.
• added new instructions in 7.12 for hair straighteners and curling irons
• exempted fixed hairdryers and fixed hand dryers from alternative format of instructions;
• excluded detachable curler surfaces from temperature rise requirement in Subclause 11.8;
– 4 – IEC 60335-2-23:2016 © IEC 2016
• clarified in Subclause 19.7 that the appliance shall not emit flame after the test;
• clarified method of test and compliance criteria in Subclause 21.101;
• added requirement in 22.13 to delineate handles on curling irons and hair straighteners;
• in 22.103, added a requirement for protection against hair being pulled into hair dryer
intake;
• revised Subclause 24.101 to indicate that protective devices shall not be self-resetting;
• reviewed and converted notes to normative text in Subclauses 19.7, 22.32, and 25.14.
The text of this standard is based on the following documents:
FDIS Report on voting
61/5135/FDIS 61/5171/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its
amendments. It was established on the basis of the fifth edition (2010) of that standard.
NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60335-1.
This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as to
convert that publication into the IEC standard: Safety requirements for appliances for skin or
hair care.
When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies
as far as is reasonable. When this standard states “addition”, “modification” or “replacement”,
the relevant text in Part 1 is to be adapted accordingly.
NOTE 2 The following numbering system is used:
– subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1;
– unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including
those in a replaced clause or subclause;
– additional annexes are lettered AA, BB, etc.
NOTE 3 The following print types are used:
– requirements: in roman type;
– test specifications: in italic type;
– notes: in small roman type.
Words in bold in the text are defined in Clause 3. When a definition concerns an adjective,
the adjective and the associated noun are also in bold.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC website under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
NOTE 4 The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations may need a transitional period following publication of a new, amended or revised IEC publication in
which to make products in accordance with the new requirements and to equip themselves for conducting new or
revised tests.
It is the recommendation of the committee that the content of the publication be adopted for implementation
nationally not earlier than 12 months or later than 36 months from the date of publication.
The following differences exist in the countries indicated below.

INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its
provisions is entrusted to appropriately qualified and experienced persons.
This standard recognizes the internationally accepted level of protection against hazards such
as electrical, mechanical, thermal, fire and radiation of appliances when operated as in
normal use taking into account the manufacturer's instructions. It also covers abnormal
situations that can be expected in practice and takes into account the way in which
electromagnetic phenomena can affect the safe operation of appliances.
This standard takes into account the requirements of IEC 60364 as far as possible so that
there is compatibility with the wiring rules when the appliance is connected to the supply
mains. However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
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 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 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of
the requirements and, if found to be substantially equivalent, may be considered to comply
with the standard.

Part 2-23: Particular requirements for appliances for skin or hair care
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

INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its
provisions is entrusted to appropriately qualified and experienced persons.
This standard recognizes the internationally accepted level of protection against hazards such
as electrical, mechanical, thermal, fire and radiation of appliances when operated as in
normal use taking into account the manufacturer's instructions. It also covers abnormal
situations that can be expected in practice and takes into account the way in which
electromagnetic phenomena can affect the safe operation of appliances.
This standard takes into account the requirements of IEC 60364 as far as possible so that
there is compatibility with the wiring rules when the appliance is connected to the supply
mains. However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
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 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 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of
the requirements and, if found to be substantially equivalent, may be considered to comply
with the standard.

the test while placed on their charging stand or integral rest.
The appliance, not connected to the supply mains, is placed in any normal position of use on
a plane inclined at an angle of 10° to the horizontal, the supply cord resting on the inclined
plane in the most unfavourable position. However, if part of an appliance comes into contact
with the horizontal supporting surface when the appliance is tilted through an angle of 10°, the
appliance is placed on a horizontal support and tilted in the most unfavourable direction
through an angle of 10°.
NOTE 101 The test on the horizontal support can be necessary for appliances provided with rollers, castors or
feet. In this case, castors or wheels can be blocked to prevent the appliance from rolling.
Appliances intended to be filled with liquid by the user in normal use are tested empty or filled
with the most unfavourable quantity of water up to the capacity indicated in the instructions.
The appliance shall not overturn unless the appliance or the part of the appliance which
overturns complies with all of the following:
– It only contains circuits operating at SELV according to 8.1.4;
– It only contains low power circuits according to 19.11.1;
– It is dropped from a height of 700 mm on a rigidly supported hard wood board 5 times, the
appliance being held in different positions likely to occur. After the drops, the appliance or
part of the appliance as relevant shall show no damage so that compliance with 15.1 and
20.2 is not impaired;
– It has a maximum weight of 450 g when ready for use;
– 16 – IEC 60335-2-23:2016+AMD1:2019 CSV
