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 sixth edition cancels and replaces the fifth edition published in 2009, Amendment 1:2012
and Amendment 2:2015. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– aligns the text with IEC 60335-1, Ed 5, and its Amendments 1 and 2;
– luminous transmission has been defined (3.1.102);
– requirements for testing parts of the appliance that are operated unattended are added
(30.2).

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 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 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.
NOTE 101 Battery-operated appliances and other DC supplied appliances are within the scope of this standard.
Dual supply appliances, either mains-supplied or battery-operated, are regarded as battery-operated appliances
when operated in the battery mode.
As far as practicable, this standard deals with the common hazards presented by appliances
that are encountered by all persons using the 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 102 Attention is drawn to the fact that
– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be
necessary;
– in many countries, additional requirements are specified by the national health authorities, the national
authorities responsible for the protection of labour and similar authorities;
– IEC 60598-1 is applicable as far as is reasonable.
NOTE 103 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).

UV appliances shall include a statement that non-users, especially children, must not be
present when the appliance is being operated.
The instructions for UV appliances shall include the substance of the following:
– a statement that UV appliances are not to be used by
• persons under the age of 18 years;
• persons who tend to freckle;
• persons with a natural red hair colour;
• persons having abnormal discoloured patches on the skin;
• persons having a large number of moles;
• persons having asymmetrical irregularly shaped moles larger than 5 mm in diameter
with variable pigmentation and irregular borders; in case of doubt, seek medical
advice;
• persons suffering from sunburn;
• persons not able to tan at all or persons that burn easily when exposed to the sun;
• persons having a history of frequent severe sunburn during childhood;
• persons suffering from or previously suffering from skin cancer or predisposed to skin
cancer;
• persons under a doctor’s 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 a UV appliance, medical advice should be sought prior to further UV
exposure;
– a statement that exposures should not exceed the minimal amount of UV radiation
exposure required to cause perceptible reddening of the skin (a person's minimal
erythemal dose (MED);
– a statement that if skin reddening (erythema) is visible approximately 16 h to 24 h after
any exposure, further exposure should cease. After one week, exposures may be
restarted from the beginning of the schedule of exposure;
– a statement that the appliance must not be used if the timer is faulty or the filter is broken
or removed;
– identification of 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 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. Avoid exposure to the internal tissues of the mouth as it may be
more susceptible to UV damage than the skin. 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
