Part 2-27: Particular requirements for appliances

for skin exposure to ultraviolet and infrared radiation

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

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60335-2-27 has been prepared by IEC technical committee 61:
Safety of household and similar electrical appliances.
This fifth edition cancels and replaces the fourth edition published in 2002, its Amendment 1
(2004) and Amendment 2 (2007). It constitutes a technical revision.
The principal changes in this edition as compared with the fourth edition of IEC 60335-2-27
are as follows (minor changes are not listed):
– clarification of the radiation measurement procedure (32.101);
– guidelines for an exposure time schedule (Annex DD).

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

provisions is entrusted to appropriately qualified and experienced persons.

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

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

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

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

electromagnetic phenomena can affect the safe operation of appliances.

This standard takes into account the requirements of IEC 60364 as far as possible so that
there is compatibility with the wiring rules when the appliance is connected to the supply
mains. However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with
in Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of
the requirements and, if found to be substantially equivalent, may be considered to comply
with the standard.

1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electrical appliances incorporating
emitters for exposing the skin to ultraviolet or infrared radiation, for household and similar
use, their rated voltage being not more than 250 V for single-phase appliances and 480 V for
other appliances.
Appliances not intended for normal household use but which nevertheless may be a source of
danger to the public, such as appliances intended to be used in tanning salons, beauty
parlours and similar premises, are also within the scope of this standard.
As far as practicable, this standard deals with the common hazards presented by appliances
that are encountered by persons using the UV appliances in tanning salons, beauty parlours
and similar premises or at 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 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;
– IEC 60598-1 is applicable as far as is reasonable.

NOTE 102 This standard does not apply to
– appliances for medical purposes;
– appliances that use UV radiation for purposes other than tanning the skin;
– 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).

– 12 – 60335-2-27 © IEC:2009(E)

The instructions for appliances having UV emitters shall contain the substance of the
following information and precautions:

– ultraviolet radiation from the sun or from UV appliances can cause skin or eye damage

that may be irreversible. These biological effects depend upon the quality and quantity of

the radiation as well as the skin sensitivity of the individual;

– the skin may develop sunburn after overexposure. Excessively repeated exposures to

ultraviolet radiation from the sun or from UV appliances may lead to premature ageing of

the skin as well as increased risk of development of skin tumours. These risks increase

with increasing cumulative UV exposure. Exposure at an early age increases the risk of

skin damage later in life;
– the unprotected eye may develop surface inflammation and in some cases damage may
occur to the retina after excessive exposure. Cataracts may develop after many repeated
exposures;
– in cases of pronounced individual sensitivity or allergic reaction to ultraviolet radiation,
medical advice is recommended before starting exposure;
– the type reference of the protective goggles to be used;
– the following precautions must be taken:
• always use the protective goggles provided. Contact lenses and sun glasses are not a
substitute for goggles;
• remove cosmetics well in advance of exposure and do not use any sunscreens or
products that accelerate tanning;
• certain medical conditions or side effects of certain medicines may be aggravated by
ultraviolet exposure. In case of doubt, seek medical advice;
• allow at least 48 h between the first two exposures;
• do not sunbathe and use the appliance on the same day;
• follow the recommendations concerning exposure durations, exposure intervals and
distances from the lamp;
• seek medical advice if persistent lumps or sores appear on the skin or if there are
changes in pigmented moles;
• protect sensitive skin parts such as scars, tattoos and genitals from exposure.
For appliances having a lid that has to be opened in normal use, the instructions shall include
a warning that the appliance must not be switched on with the lid in the closed position and
that, before closing the lid for storage, the appliance must be disconnected from the supply
and allowed to cool down.
NOTE 101 This warning is not required if the appliance complies with the tests of 19.2 and 19.3.

The instructions for appliances having IR emitters shall include advice for the protection of
the eyes against exposure to infrared radiation and advise that adequate precautions must be
taken to safeguard the user against the dangers of excessive exposure.
If the “Not for household use” symbol is used, its meaning shall be explained.
7.14 Addition:
The height of the “not for household use” symbol shall be at least 10 mm.
Compliance is checked by measurement.

Part 2-27: Particular requirements for appliances

for skin exposure to ultraviolet and infrared radiation

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 consolidated version of IEC 60335-2-27 consists of the fifth edition (2009)
[documents 61/3911/FDIS and 61/3969/RVD] and its amendment 1 (2012) [documents
61/4444/FDIS and 61/4497/RVD]. It bears the edition number 5.1.
The technical content is therefore identical to the base edition and its amendment and
has been prepared for user convenience. A vertical line in the margin shows where the
base publication has been modified by amendment 1. Additions and deletions are
displayed in red, with deletions being struck through.

60335-2-27  IEC:2009+A1:2012(E) – 5 –

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

provisions is entrusted to appropriately qualified and experienced persons.

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

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

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

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

electromagnetic phenomena can affect the safe operation of appliances.

This standard takes into account the requirements of IEC 60364 as far as possible so that
there is compatibility with the wiring rules when the appliance is connected to the supply
mains. However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with
in Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of
the requirements and, if found to be substantially equivalent, may be considered to comply
with the standard.

Part 2-27: Particular requirements for appliances

for skin exposure to ultraviolet and infrared radiation

1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electrical appliances incorporating
emitters for exposing the skin to ultraviolet or infrared radiation, for household and similar
use, their rated voltage being not more than 250 V for single-phase appliances and 480 V for
other appliances.
Appliances not intended for normal household use but which nevertheless may be a source of
danger to the public, such as appliances intended to be used in tanning salons, beauty
parlours and similar premises, are also within the scope of this standard.
As far as practicable, this standard deals with the common hazards presented by appliances
that are encountered by persons using the UV appliances in tanning salons, beauty parlours
and similar premises or at 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 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;
– IEC 60598-1 is applicable as far as is reasonable.

NOTE 102 This standard does not apply to
– appliances for medical purposes;
– appliances that use UV radiation for purposes other than tanning the skin;
– 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).

be stated that they are only to be replaced by types marked with an equivalency code, the

UV component of which falls within the UV component equivalency code range that is

marked on the appliance. In this case, an example of the equivalency code shall be given

and the UV component aspect of the fluorescent UV lamp for tanning equivalency code

shall be explained.
The instructions for appliances having UV emitters UV appliances shall contain the

substance of the following information and precautions:

– ultraviolet radiation from the sun or from UV appliances can cause skin or eye damage

that may be irreversible. These biological effects depend upon the quality and quantity of
the radiation as well as the skin sensitivity of the individual;
– the skin may develop sunburn after overexposure. Excessively repeated exposures to
ultraviolet radiation from the sun or from UV appliances may lead to premature ageing of
the skin as well as increased risk of development of skin tumours. These risks increase
with increasing cumulative UV exposure. Exposure at an early age increases the risk of
skin damage later in life;
– the unprotected eye may develop surface inflammation and in some cases damage may
occur to the retina after excessive exposure. Cataracts may develop after many repeated
exposures;
– in cases of pronounced individual sensitivity or allergic reaction to ultraviolet radiation,
medical advice is recommended before starting exposure;
– the type reference of the protective goggles to be used;
– the following precautions must be taken:
• always use the protective goggles provided. Contact lenses and sun glasses are not a
substitute for goggles;
• remove cosmetics, fragrances, and skin care products well in advance of exposure and
do not use any sunscreens or products that accelerate tanning;
• certain medical conditions or side effects of certain medicines may be aggravated by
ultraviolet exposure. In case of doubt, seek medical advice;
• allow at least 48 h between the first two exposures;
• do not sunbathe and use the appliance on the same day;
• follow the recommendations concerning exposure durations, exposure intervals and
distances from the lamp;
• seek medical advice if persistent lumps or sores appear on the skin or if there are
changes in pigmented moles;
• protect sensitive skin parts such as scars, tattoos and genitals from exposure.
For appliances having a lid that has to be opened in normal use, the instructions shall include
a warning that the appliance must not be switched on with the lid in the closed position and
that, before closing the lid for storage, the appliance must be disconnected from the supply
and allowed to cool down.
NOTE 101 This warning is not required if the appliance complies with the tests of 19.2 and 19.3.
The instructions for appliances having IR emitters shall include advice for the protection of
the eyes against exposure to infrared radiation and advise that adequate precautions must be
taken to safeguard the user against the dangers of excessive exposure.
If the “Not for household use” symbol is used, its meaning shall be explained.

Part 2-27: Particular requirements for appliances
for skin exposure to ultraviolet and infrared optical radiation
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 consolidated version of the official IEC Standard and its amendments has been
prepared for user convenience.
IEC 60335-2-27 edition 5.2 contains the fifth edition (2009-12) [documents 61/3911/FDIS
and 61/3969/RVD], its amendment 1 (2012-11) [documents 61/4444/FDIS and 61/4497/
RVD] and its amendment 2 (2015-04) [documents 61/4876/FDIS and 61/4912/RVD]
including its corrigenda 1 (2015-05) and 2 (2016-12).
In this Redline version, a vertical line in the margin shows where the technical content
is modified by amendments 1 and 2. Additions and deletions are displayed in red, with
deletions being struck through. A separate Final version with all changes accepted is
available in this publication.

+AMD1:2012+AMD2:2015 © IEC 2015
International Standard IEC 60335-2-27 has been prepared by IEC technical committee 61:
Safety of household and similar electrical appliances.
The principal changes in this edition as compared with the fourth edition of IEC 60335-2-27
are as follows (minor changes are not listed):
– clarification of the radiation measurement procedure (32.101);
– guidelines for an exposure time schedule (Annex DD).
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 fourth edition (2001) 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
exposure to ultraviolet and infrared radiation.
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 the base publication and its amendments will
remain unchanged until the stability date indicated on the IEC web site 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 this publication be adopted for implementation
nationally not earlier than 12 months or later than 36 months from the date of publication.

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

HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
SAFETY –
Part 2-27: Particular requirements for appliances
for skin exposure to ultraviolet and infrared optical radiation

1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electrical appliances incorporating
emitters for exposing the skin to ultraviolet or infrared optical radiation (wavelength 100 nm to
1 mm), for household and similar use, their rated voltage being not more than 250 V for
single-phase appliances and 480 V for other appliances.
Appliances not intended for normal household use but which nevertheless may be a source of
danger to the public, such as appliances intended to be used in tanning salons, beauty
parlours and similar premises, are also within the scope of this standard.
As far as practicable, this standard deals with the common hazards presented by appliances
that are encountered by persons using the UV appliances in tanning salons, beauty parlours
and similar premises or at 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 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;
– IEC 60598-1 is applicable as far as is reasonable.
NOTE 102 This standard does not apply to
– appliances for skin or hair care (IEC 60335-2-23);
– sauna heating appliances and infrared cabins (IEC 60335-2-53);
– cosmetic and beauty care appliances incorporating lasers and intense light sources (IEC 60335-2-113) ;
– appliances for medical purposes (IEC 60601);
– appliances that use UV radiation for purposes other than tanning the skin;
– 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).

Part 2-27: Particular requirements for appliances

for skin exposure to ultraviolet and infrared radiation

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

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

provisions is entrusted to appropriately qualified and experienced persons.

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

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

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

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

electromagnetic phenomena can affect the safe operation of appliances.

This standard takes into account the requirements of IEC 60364 as far as possible so that
there is compatibility with the wiring rules when the appliance is connected to the supply
mains. However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with
in Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of
the requirements and, if found to be substantially equivalent, may be considered to comply
with the standard.

The instructions for appliances having UV emitters shall contain the substance of the
following information and precautions:

– ultraviolet radiation from the sun or from UV appliances can cause skin or eye damage

that may be irreversible. These biological effects depend upon the quality and quantity of

the radiation as well as the skin sensitivity of the individual;

– the skin may develop sunburn after overexposure. Excessively repeated exposures to

ultraviolet radiation from the sun or from UV appliances may lead to premature ageing of

the skin as well as increased risk of development of skin tumours. These risks increase

with increasing cumulative UV exposure. Exposure at an early age increases the risk of

skin damage later in life;
– the unprotected eye may develop surface inflammation and in some cases damage may
occur to the retina after excessive exposure. Cataracts may develop after many repeated
exposures;
– in cases of pronounced individual sensitivity or allergic reaction to ultraviolet radiation,
medical advice is recommended before starting exposure;
– the type reference of the protective goggles to be used;
– the following precautions must be taken:
 always use the protective goggles provided. Contact lenses and sun glasses are not a
substitute for goggles;
 remove cosmetics well in advance of exposure and do not use any sunscreens or
products that accelerate tanning;
 certain medical conditions or side effects of certain medicines may be aggravated by
ultraviolet exposure. In case of doubt, seek medical advice;
 allow at least 48 h between the first two exposures;
 do not sunbathe and use the appliance on the same day;
 follow the recommendations concerning exposure durations, exposure intervals and
distances from the lamp;
 seek medical advice if persistent lumps or sores appear on the skin or if there are
changes in pigmented moles;
 protect sensitive skin parts such as scars, tattoos and genitals from exposure.
For appliances having a lid that has to be opened in normal use, the instructions shall include
a warning that the appliance must not be switched on with the lid in the closed position and
that, before closing the lid for storage, the appliance must be disconnected from the supply
and allowed to cool down.
NOTE 101 This warning is not required if the appliance complies with the tests of 19.2 and 19.3.

The instructions for appliances having IR emitters shall include advice for the protection of
the eyes against exposure to infrared radiation and advise that adequate precautions must be
taken to safeguard the user against the dangers of excessive exposure.

Part 2-27: Particular requirements for appliances

for skin exposure to ultraviolet and infrared radiation

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 Consolidated version of IEC 60335-2-27 bears the edition number 5.1. It consists of
the fifth edition (2009-12) [documents 61/3911/FDIS and 61/3969/RVD] and its
amendment 1 (2012-11) [documents 61/4444/FDIS and 61/4497/RVD]. The technical
content is identical to the base edition and its amendment.
In this Redline version, a vertical line in the margin shows where the technical content
is modified by amendment 1. Additions and deletions are displayed in red, with
deletions being struck through. A separate Final version with all changes accepted is
available in this publication.
This publication has been prepared for user convenience.

+AMD1:2012 CSV © IEC 2012
International Standard IEC 60335-2-27 has been prepared by IEC technical committee 61:
Safety of household and similar electrical appliances.

The principal changes in this edition as compared with the fourth edition of IEC 60335-2-27
are as follows (minor changes are not listed):

– clarification of the radiation measurement procedure (32.101);

– guidelines for an exposure time schedule (Annex DD).

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 fourth edition (2001) 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
exposure to ultraviolet and infrared radiation.
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 the base publication and its amendment will
remain unchanged until the stability date indicated on the IEC web site 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 this 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.
– 7.1: The markings are different (USA).

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

provisions is entrusted to appropriately qualified and experienced persons.

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

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

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

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

electromagnetic phenomena can affect the safe operation of appliances.

This standard takes into account the requirements of IEC 60364 as far as possible so that
there is compatibility with the wiring rules when the appliance is connected to the supply
mains. However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with
in Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of
the requirements and, if found to be substantially equivalent, may be considered to comply
with the standard.

for skin exposure to ultraviolet and infrared radiation

1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electrical appliances incorporating
emitters for exposing the skin to ultraviolet or infrared radiation, for household and similar
use, their rated voltage being not more than 250 V for single-phase appliances and 480 V for
other appliances.
Appliances not intended for normal household use but which nevertheless may be a source of
danger to the public, such as appliances intended to be used in tanning salons, beauty
parlours and similar premises, are also within the scope of this standard.
As far as practicable, this standard deals with the common hazards presented by appliances
that are encountered by persons using the UV appliances in tanning salons, beauty parlours
and similar premises or at 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 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;
– IEC 60598-1 is applicable as far as is reasonable.

NOTE 102 This standard does not apply to
– appliances for medical purposes;
– appliances that use UV radiation for purposes other than tanning the skin;
– 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).

The instructions for appliances having UV emitters UV appliances shall contain the

substance of the following information and precautions:

– ultraviolet radiation from the sun or from UV appliances can cause skin or eye damage

that may be irreversible. These biological effects depend upon the quality and quantity of

the radiation as well as the skin sensitivity of the individual;

– the skin may develop sunburn after overexposure. Excessively repeated exposures to

ultraviolet radiation from the sun or from UV appliances may lead to premature ageing of

the skin as well as increased risk of development of skin tumours. These risks increase

with increasing cumulative UV exposure. Exposure at an early age increases the risk of
skin damage later in life;
– the unprotected eye may develop surface inflammation and in some cases damage may
occur to the retina after excessive exposure. Cataracts may develop after many repeated
exposures;
– in cases of pronounced individual sensitivity or allergic reaction to ultraviolet radiation,
medical advice is recommended before starting exposure;
– the type reference of the protective goggles to be used;
– the following precautions must be taken:
• always use the protective goggles provided. Contact lenses and sun glasses are not a
substitute for goggles;
• remove cosmetics, fragrances, and skin care products well in advance of exposure and
do not use any sunscreens or products that accelerate tanning;
• certain medical conditions or side effects of certain medicines may be aggravated by
ultraviolet exposure. In case of doubt, seek medical advice;
• allow at least 48 h between the first two exposures;
• do not sunbathe and use the appliance on the same day;
• follow the recommendations concerning exposure durations, exposure intervals and
distances from the lamp;
• seek medical advice if persistent lumps or sores appear on the skin or if there are
changes in pigmented moles;
• protect sensitive skin parts such as scars, tattoos and genitals from exposure.

Part 2-27: Particular requirements for appliances
for skin exposure to ultraviolet and infrared optical radiation

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.
DISCLAIMER
This Consolidated version is not an official IEC Standard and has been prepared for
user convenience. Only the current versions of the standard and its amendment(s)
are to be considered the official documents.

+AMD2:2015 CSV © IEC 2015

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

HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
SAFETY –
Part 2-27: Particular requirements for appliances
for skin exposure to ultraviolet and infrared optical radiation

1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electrical appliances incorporating
emitters for exposing the skin to ultraviolet or infrared optical radiation (wavelength 100 nm to
1 mm), for household and similar use, their rated voltage being not more than 250 V for
single-phase appliances and 480 V for other appliances.
Appliances not intended for normal household use but which nevertheless may be a source of
danger to the public, such as appliances intended to be used in tanning salons, beauty
parlours and similar premises, are also within the scope of this standard.
As far as practicable, this standard deals with the common hazards presented by appliances
that are encountered by persons using the UV appliances in tanning salons, beauty parlours
and similar premises or at 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 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;
– IEC 60598-1 is applicable as far as is reasonable.
NOTE 102 This standard does not apply to
– appliances for skin or hair care (IEC 60335-2-23);
– sauna heating appliances and infrared cabins (IEC 60335-2-53);
– cosmetic and beauty care appliances incorporating lasers and intense light sources (IEC 60335-2-113) ;
– appliances for medical purposes (IEC 60601);
– appliances that use UV radiation for purposes other than tanning the skin;
– 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).

– a statement that the appliance must not be used if the timer is faulty or the filter is broken
or removed;
– identification of alternative components that may influence the ultraviolet radiation, such
as filters and reflectors;
– identification of replaceable UV emitters and a statement that they are only to be
replaced by types marked on the appliance. For fluorescent UV lamps for tanning, it shall
be stated that they are only to be replaced by types marked with an equivalency code, the
UV component of which falls within the UV component equivalency code range that is
marked on the appliance. In this case, an example of the equivalency code shall be given
and the UV component aspect of the fluorescent UV lamp for tanning equivalency code
shall be explained.
The instructions for UV appliances having UV emitters shall contain the substance of the
following information and precautions:
– ultraviolet radiation from the sun or from UV appliances can cause skin or eye damage
that may be irreversible. These biological effects depend upon the quality and quantity of
the radiation as well as the skin sensitivity of the individual;
– the skin may develop sunburn after overexposure. Excessively repeated exposures to
ultraviolet radiation from the sun or from UV appliances may lead to premature ageing of
the skin as well as increased risk of development of skin tumours. These risks increase
with increasing cumulative UV exposure. Exposure at an early age increases the risk of
skin damage later in life;
– the unprotected eye may develop surface inflammation and in some cases damage may
occur to the retina after excessive exposure. Cataracts may develop after many repeated
exposures;
– in cases of pronounced individual sensitivity or allergic reaction to ultraviolet radiation,
medical advice is recommended before starting exposure;
– the type reference of the protective goggles to be used;
– the following precautions must be taken:
• always use the protective goggles provided. Contact lenses and sun glasses are not a
substitute for goggles;
• remove cosmetics, fragrances, and skin care products well in advance of exposure and
do not use any sunscreens or products that accelerate tanning;
• certain medical conditions or side effects of certain medicines may be aggravated by
ultraviolet exposure. In case of doubt, seek medical advice;
• allow at least 48 h between the first two exposures;
• do not sunbathe and use the appliance on the same day;
• follow the recommendations concerning exposure durations, exposure intervals and
distances from the lamp;
• seek medical advice if persistent lumps or sores appear on the skin or if there are
changes in pigmented moles;
• protect sensitive skin parts such as scars, tattoos and genitals from exposure.
For appliances having a lid that has to be opened in normal use, the instructions shall include
a warning that the appliance must not be switched on with the lid in the closed position and
that, before closing the lid for storage, the appliance must be disconnected from the supply
and allowed to cool down.
NOTE 101 This warning is not required if the appliance complies with the tests of 19.2 and 19.3.
The instructions for appliances having incorporating VIS emitters or IR emitters shall include
the substance of the following:

– 14 – IEC 60335-2-27:2009+AMD1:2012
+AMD2:2015 CSV © IEC 2015
– advice for the protection of the eyes against exposure to visible and infrared radiation and
advise that adequate precautions must be taken to safeguard the user against the dangers
of excessive exposure.
– a statement that VIS appliances and IR appliances are not to be used by
• persons suffering from sunburn;
• persons under medical care for diseases that involve photosensitivity;
• persons receiving photosensitising medications.
– a statement that if unexpected side effects, such as itching, occur within 48 h of the first
session of using an appliance, medical advice should be sought prior to further exposure;
– information concerning the intended exposure distance (unless this is controlled by the
construction of the appliance);
– recommended schedule of exposure specifying duration and intervals (based on the
emitter characteristics, distances);
– a statement that the appliance must not be used if the timer is faulty or the filter is broken
or removed;
– identification of alternative components that may influence the radiation, such as filters
and reflectors;
– identification of replaceable emitters and a statement that they are only to be replaced by
types marked on the appliance;
– instruction to use goggles and an information about the maximum exposure time (not
necessary if the appliance complies with the limits for the exempt group as defined in
6.1.1 of IEC 62471:2006 when tested as required by 32.103).
If the “Not for household use” symbol is either of the symbols are used, its their meaning shall
be explained:
– “Not for household use” symbol;
– symbol IEC 60417-6301 (2015-03).
7.14 Addition:
The height of the “not for household use” symbol shall be at least 10 mm.
The diameter of the UV lamp circle in symbol symbol IEC 60417-6301 (2015-03) shall be at
least 20 mm.
Compliance is checked by measurement.
7.15 Addition:
The additional warnings and markings specified in 7.1 of this Part 2 shall be visible after the
appliance has been installed and without removal of a cover.
8 Protection against access to live parts
This clause of Part 1 is applicable except as follows.
NOTE 101 Compliance with the relevant requirements of Section 8 of IEC 60598-1 is to be maintained during the
replacement of emitters, unless the instructions forbid replacement by the user and tools are needed.
8.1.3 Not applicable.
