Part 2-115: Particular requirements for skin beauty care appliances

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) 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 60335-2-115 has been prepared by IEC technical committee 61:
Safety of household and similar electrical appliances.
The text of this International Standard is based on the following documents:
FDIS Report on voting
61/6132/FDIS 61/6178/RVD
Full information on the voting for the approval of this International Standard can be found in the
report on voting indicated in the above table.
The language used for the development of this International Standard is English.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts of the IEC 60335 series, under the general title: Household and similar
electrical appliances – Safety, can be found on the IEC website.

This part 2 is to be used in conjunction with the fifth edition of IEC 60335-1:2010 and its
amendments.
NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60335-1.
This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as to convert
that publication into the IEC standard: Particular requirements for skin beauty care appliances.
When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies as
far as is reasonable. When this standard states “addition”, “modification” or “replacement”, the
relevant text in Part 1 is to be adapted accordingly.
NOTE 2 The following numbering system is used:
– subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1;
– unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including
those in a replaced clause or subclause;
– additional annexes are lettered AA, BB, etc.
NOTE 3 The following print types are used:
− requirements: in roman type;
− test specifications: in italic type;
− notes: in small roman type.
Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the
associated noun are also in bold.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document 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.

IMPORTANT – The "colour inside" logo on the cover page of this document indicates
that it contains colours which are considered to be useful for the correct understanding
of its contents. Users should therefore print this document using a colour printer.

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.
HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES – SAFETY –

Part 2-115: Particular requirements for skin beauty care appliances

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 skin beauty care of

7.14 Addition:
When the instructions contain information for cleaning or disinfection of the appliance or parts
of it, compliance is also checked by rubbing the marking for 15 s with a piece of cloth soaked
with the cleaning lotion or disinfectant stated in instructions.
7.15 Addition:
The outer diameter of the circle in prohibition sign ISO 7010-P026 (2011-05) shall be at least
10 mm.
The outer diameter of the circle in prohibition sign “Not for household use” shall be at least
10 mm.
Compliance is checked by measurement.
8 Protection against access to live parts
This clause of Part 1 is applicable except as follows.
Addition:
For radio frequency appliances and electrical stimulators, the applied parts are not
considered to be live parts.
9 Starting of motor-operated appliances
This clause of Part 1 is not applicable.

10 Power input and current
This clause of part 1 is applicable except as follows:
10.101 The power input or current of electrical stimulators shall not deviate from the rated
power input or rated current marked on the appliance by more than the deviation shown in
Table 1 or Table 2 respectively.
Compliance is checked as follows.
The appliance is operated at rated voltage with a load resistance applied to the output that
maximizes the power input or current.
The appliance is operated for the maximum period specified in the instructions or maximum
setting of an incorporated timer, whichever is shorter.
The maximum value of power input or current, averaged over any 5 s period is obtained. The
maximum of the average values so obtained is taken as the maximum value of the power input
or current.
If the appliance cannot operate as intended when applying a load resistance, the manufacturer
may specify a different method to achieve the required input power or current and that method
shall be applied.
10.102 The power input or current of radio frequency appliances shall not deviate from the
rated power input or rated current marked on the appliance by more than the deviation shown
in Table 1 or Table 2 respectively.
Compliance is checked as follows.
The appliance is operated at rated voltage with a load resistance applied to the output that
maximizes the power input or current.
The appliance is operated for the maximum period specified in the instructions or maximum
setting of an incorporated timer, whichever is shorter.
The maximum value of power input or current, averaged over any 5 s period is obtained. The
maximum of the average values so obtained is taken as the maximum value of the power input
or current.
To carry out the test, a specially prepared sample may be needed with the load resistor attached
across the output applicator.
If the appliance cannot operate as intended when applying a load resistance, the manufacturer
may specify a different method to achieve the required input power or current and that method
shall be applied.

11.2 Addition:
Appliances intended to be used on a stand or attached to a support are placed to give the most
unfavourable results.
Hand-held appliances with an integral rest are also tested when placed on their rest away from
the walls of the test corner.
11.3 Addition:
Where the external accessible surfaces, other than the applied parts, are suitably flat and
access permits, then the test probe of Figure 101 is used to measure the temperature rises of
external accessible surfaces specified in Table 101. The probe is applied with a force of
4 N ± 1 N to the surface in such a way that the best possible contact between the probe and
the surface is ensured. The measurement i
