Appliances not intended for normal household use but that nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard. As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the 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.
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.
This standard does not apply to
- appliances intended exclusively for industrial purposes;
- appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);
- electric foot care appliances that do not contain motors and other electric appliances for the care of skin or hair (IEC 60335-2-23)
- electric appliances for beauty care of persons and intended for household, commercial and similar purposes (IEC 60335-2-115).
This fifth edition cancels and replaces the fourth edition published in 2002, Amendment 1: 2008 and Amendment 2:2013. This edition constitutes a technical revision.

Dans la mesure du possible, la présente norme traite des dangers ordinaires présentés par les appareils et encourus par tous les individus à l'intérieur et autour de l'habitation. Cependant, elle ne tient généralement pas compte:
- des personnes (y compris des enfants) dont les capacités physiques, sensorielles ou mentales ou le manque d’expérience et de connaissance les empêchent d’utiliser l’appareil en toute sécurité sans surveillance ou instruction;
- de l’utilisation de l’appareil comme jouet par des enfants.
L’attention est attirée sur le fait que:
- pour les appareils destinés à être utilisés dans des véhicules ou à bord de navires ou d'avions, des exigences supplémentaires peuvent être nécessaires;
- dans de nombreux pays, des exigences supplémentaires sont spécifiées par les organismes nationaux de la santé, par les organismes nationaux responsables de la protection des travailleurs, par les organismes nationaux responsables de l'alimentation en eau et par des organismes similaires.
La présente norme ne s’applique pas:
- aux appareils exclusivement destinés à un usage industriel;
- aux appareils destinés à être utilisés dans des locaux présentant des conditions particulières, telles que la présence d'une atmosphère corrosive ou explosive (poussières, vapeur ou gaz);
- aux appareils électriques de soins des pieds sans moteur et aux autres appareils électriques de soins de la peau ou des cheveux (IEC 60335-2-23);
- aux appareils électriques de soins de beauté destinés à un usage domestique, commercial ou analogue (IEC 60335-2-115).
Cette cinquième édition annule et remplace la quatrième édition parue en 2002, l'Amendement 1:2008 et l'Amendement 2:2013. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- alignement du texte sur l’IEC 60335-1, Ed 5 et ses Amendements 1 et 2;
- conversion d’une note en texte normatif (11.8);
- ajout d’exigences relatives aux surfaces accessibles extérieures (Article 11);
- ajout d’exigences de stabilité alternatives relatives aux appareils portatifs (20.2);
- ajout d’un nouvel essai de résistance mécanique pour les appareils portatifs (21.1, 21.101).
La présente partie 2 doit être utilisée conjointement avec la dernière édition de l’IEC 60335-1 et ses amendements. Elle a été établie sur la base de la cinquième édition (2010) de cette norme.

Part 2-32: Particular requirements for massage 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 60335-2-32 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, Amendment 1:

2008 and Amendment 2:2013. 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;
– note is converted to normative text (11.8);

– additional requirements for temperatures of external accessible surfaces (Clause 11);

– alternative stability requirements for hand-held appliances (20.2);
– new mechanical strength test for hand-held appliances (21.1, 21.101).

The text of this International Standard is based on the following documents:
CDV Report on voting
61/5747/CDV 61/5840A/RVC

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.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its

amendments. It was established on the basis of the fifth edition (2010) of that standard.

NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60335-1.

This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as to

convert that publication into the IEC standard: Safety requirements for massage 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.

The following differences exist in the countries indicated below.

– 6.1: Class 0 portable appliances and Class I portable appliances are allowed (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.
