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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 60335-2-116 has been prepared by IEC technical committee 61: Safety of household and
similar electrical appliances. It is an International Standard.
This second edition cancels and replaces the first edition published in 2019. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) alignment with IEC 60335-1:2020;
b) deletion or conversion of some notes to normative text (Clause 1);
c) introduction of surface temperature limits (11.3, 11.8);
d) introduction of test probe 19 (8.1.1, 20.2);
e) revision of Clause 20.2.105 with a new entrapment force test method, including time-force
profiles and updated force limits.
The text of this International Standard is based on the following documents:
Draft Report on voting
61/7493/FDIS 61/7513/RVD
Full information on the voting for its approval 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 was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/publications.
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 latest edition of IEC 60335-1 and its
amendments unless that edition precludes it; in that case, the latest edition that does not
preclude it is used. It was established on the basis of the sixth edition (2020) 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: Particular requirements for furniture with electrically
motorized parts.
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 state "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:
– test specifications: in italic 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 webstore.iec.ch in the data related to the
specific document. At this date, the document will be
– reconfirmed,
– withdrawn, or
– revised.
NOTE 4 The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations can 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.
Guidance documents concerning the application of the safety requirements for appliances can
be accessed via TC 61 supporting documents on the IEC website
https://www.iec.ch/tc61/supportingdocuments
This information is given for the convenience of users of this International Standard and does
not constitute a replacement for the normative text in this standard.
This standard only covers the risks associated with electrically motorized parts 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 such appliances. It does not cover
risks associated with furniture containing heating elements.
Other safety aspects of furniture with and without electrically motorized parts are covered by
the standards developed by ISO TC 136.
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 can 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 publications, basic safety publications and group safety publications 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.
NOTE 3 Standards dealing with non-safety aspects of household appliances are:
– IEC standards published by TC 59 concerning methods of measuring performance;
– CISPR 11, CISPR 14-1 and relevant IEC 61000-3 series standards concerning electromagnetic emissions;
– CISPR 14-2 concerning electromagnetic immunity;
– IEC standards published by TC 111 concerning environmental matters.
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.

1 Scope
This clause of Part 1 is replaced by the following.
This part of IEC 60335 deals with the safety of furniture with electrically motorized parts
intended for household and similar purposes, their rated voltage being not more than 250 V
including direct current (DC) supplied furniture and battery-operated furniture.

– persons whose physical, sensory or mental capabilities, or lack of experience and
knowledge prevents them from using the furniture incorporating electric appliances, parts
or components safely without supervision or instruction;
– children playing with furniture incorporating electrically motorized parts.
Additional requirements can be necessary for furniture incorporating electrically motorized
parts intended to be used in vehicles or on board ships or aircraft. In many countries, additional
requirements are specified by the national health authorities, the national authorities
responsible for the protection of labour, the national authorities for fire protection and similar
authorities.
This standard does not apply to:
– furniture containing heating elements;
– furniture intended to be used in locations where special conditions prevail, such as the
presence of a corrosive or explosive atmosphere (dust, vapour or gas);

Partie 2-116: Exigences particulières pour les mobiliers
avec des parties à motorisation électrique

AVANT-PROPOS
1) La Commission Électrotechnique Internationale (IEC) est une organisation mondiale de normalisation composée
de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l'IEC). L'IEC a pour objet de
favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines de
l'électricité et de l'électronique. À cet effet, l'IEC – entre autres activités – publie des Normes internationales,
des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au public (PAS) et des
Guides (ci-après dénommés "Publication(s) de l'IEC"). Leur élaboration est confiée à des comités d'études, aux
travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les organisations
internationales, gouvernementales et non gouvernementales, en liaison avec l'IEC, participent également aux
travaux. L'IEC collabore étroitement avec l'Organisation Internationale de Normalisation (ISO), selon des
conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de l'IEC concernant les questions techniques représentent, dans la mesure du
possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l'IEC intéressés
sont représentés dans chaque comité d'études.
3) Les Publications de l'IEC se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de l'IEC. Tous les efforts raisonnables sont entrepris afin que
l'IEC s'assure de l'exactitude du contenu technique de ses publications; l'IEC ne peut pas être tenue responsable
de l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de l'IEC s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de l'IEC dans leurs publications nationales
et régionales. Toutes divergences entre toutes Publications de l'IEC et toutes publications nationales ou
régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) L'IEC elle-même ne fournit aucune attestation de conformité. Des organismes de certification indépendants
fournissent des services d'évaluation de conformité et, dans certains secteurs, accèdent aux marques de
conformité de l'IEC. L'IEC n'est responsable d'aucun des services effectués par les organismes de certification
indépendants.
6) Tous les utilisateurs doivent s'assurer qu'ils sont en possession de la dernière édition de cette publication.
7) Aucune responsabilité ne doit être imputée à l'IEC, à ses administrateurs, employés, auxiliaires ou mandataires,
y compris ses experts particuliers et les membres de ses comités d'études et des Comités nationaux de l'IEC,
pour tout préjudice causé en cas de dommages corporels et matériels, ou de tout autre dommage de quelque
nature que ce soit, directe ou indirecte, ou pour supporter les coûts (y compris les frais de justice) et les dépenses
découlant de la publication ou de l'utilisation de cette Publication de l'IEC ou de toute autre Publication de l'IEC,
ou au crédit qui lui est accordé.
8) L'attention est attirée sur les références normatives citées dans cette publication. L'utilisation de publications
référencées est obligatoire pour une application correcte de la présente publication.
9) L'IEC attire l'attention sur le fait que la mise en application du présent document peut entraîner l'utilisation d'un
ou de plusieurs brevets. L'IEC ne prend pas position quant à la preuve, à la validité et à l'applicabilité de tout
droit de brevet revendiqué à cet égard. À la date de publication du présent document, l'IEC n'avait pas reçu
notification qu'un ou plusieurs brevets pouvaient être nécessaires à sa mise en application. Toutefois, il y a lieu
d'avertir les responsables de la mise en application du présent document que des informations plus récentes
sont susceptibles de figurer dans la base de données de brevets, disponible à l'adresse https://patents.iec.ch.
L'IEC ne saurait être tenue pour responsable de ne pas avoir identifié de tels droits de brevets et de ne pas avoir
signalé leur existence.
L'IEC 60335-2-116 a été établie par le comité d'études 61 de l'IEC: Sécurité des appareils
électrodomestiques et analogues. Il s'agit d'une Norme internationale.
Cette deuxième édition annule et remplace la première édition parue en 2019. Cette édition
constitue une révision technique.

Directives ISO/IEC, Partie 1 et les Directives ISO/IEC, Supplément IEC, disponibles sous
www.iec.ch/members_experts/refdocs. Les principaux types de documents développés par
l'IEC sont décrits plus en détail sous www.iec.ch/publications.
Une liste de toutes les parties de la série IEC 60335, publiées sous le titre général: Appareils
électrodomestiques et analogues – Sécurité, peut être consultée sur le site web de l'IEC.
La présente partie 2 doit être utilisée conjointement avec la dernière édition de l'IEC 60335-1
et ses amendements sauf si cette édition l'exclut. Dans ce cas, la dernière édition qui n'exclut
pas la présente partie 2 est utilisée. Elle a été établie sur la base de la sixième édition (2020)
de cette norme.
NOTE 1 L'expression "la Partie 1" utilisée dans la présente norme fait référence à l'IEC 60335-1.
La présente Partie 2 complète ou modifie les articles correspondants de l'IEC 60335-1, de façon
à transformer cette publication en norme IEC: Exigences particulières pour les mobiliers avec
des parties à motorisation électrique.
Lorsqu'un paragraphe particulier de la Partie 1 n'est pas mentionné dans cette Partie 2, ce
paragraphe s'applique pour autant que cela soit raisonnable. Lorsque la présente norme
mentionne "addition", "modification" ou "remplacement", le texte correspondant de la Partie 1
doit être adapté en conséquence.
NOTE 2 Le système de numérotation suivant est utilisé:
– les paragraphes, tableaux et figures qui s'ajoutent à ceux de la Partie 1 sont numérotés à partir de 101;
– à l'exception de celles qui sont dans un nouveau paragraphe ou de celles qui concernent des notes de la Partie 1,
les notes sont numérotées à partir de 101, y compris celles des articles ou paragraphes qui sont remplacés;
– les annexes qui sont ajoutées sont désignées AA, BB, etc.
NOTE 3 Les caractères d'imprimerie suivants sont utilisés:
– modalités d'essais: caractères italiques.
Les termes en gras dans le texte sont définis à l'Article 3. Lorsqu'une définition concerne un adjectif, l'adjectif et le
nom associé figurent également en gras.
Le comité a décidé que le contenu de ce document ne sera pas modifié avant la date de stabilité
indiquée sur le site web de l'IEC sous webstore.iec.ch dans les données relatives au document
recherché. À cette date, le document sera
– reconduit,
– supprimé, ou
– révisé.
NOTE 4 L'attention des Comités nationaux est attirée sur le fait que les fabricants d'appareils et les organismes
d'essai peuvent avoir besoin d'une période transitoire après la publication d'une nouvelle publication IEC, ou d'une
publication amendée ou révisée, pour fabriquer des produits conformes aux nouvelles exigences et pour adapter
leurs équipements aux nouveaux essais ou aux essais révisés.
Le comité recommande que le contenu de cette publication soit entériné au niveau national au plus tôt 12 mois et au
plus tard 36 mois après la date de publication.

INTRODUCTION
Il a été admis par hypothèse, en établissant la présente Norme internationale, que l'exécution
de ses dispositions était confiée à des personnes expérimentées et ayant une qualification
appropriée.
Les documents de recommandations concernant l'application des exigences de sécurité pour
les appareils peuvent être consultés dans les documents de support du CE 61, accessibles sur
le site web de l'IEC à l'adresse https://www.iec.ch/tc61/supportingdocuments.
Cette information est donnée à l'intention des utilisateurs de la présente Norme internationale
et ne constitue nullement un remplacement du texte normatif de la présente norme.
La présente norme traite uniquement des risques associés aux parties à motorisation électrique
lorsqu'elles fonctionnent comme en usage normal conformément aux instructions du fabricant.
Elle couvre également les situations anormales auxquelles on peut s'attendre dans la pratique
et elle tient compte de la façon dont les phénomènes électromagnétiques peuvent altérer le
fonctionnement sûr des appareils. Elle ne couvre pas les risques associés aux mobiliers
comportant des éléments chauffants.
Les autres aspects liés à la sécurité du mobilier avec et sans parties à motorisation électrique
sont couverts par les normes élaborées par le TC 136 de l'ISO.
Cette norme tient compte autant que possible des exigences de l'IEC 60364, de façon à rester
compatible avec les règles d'installation quand l'appareil est raccordé au réseau d'alimentation.
Cependant, des règles d'installation nationales peuvent être différentes.
Si un appareil relevant du domaine d'application de la présente norme comporte également des
fonctions couvertes par une autre partie 2 de l'IEC 60335, la partie 2 correspondante est
appliquée à chaque fonction séparément, dans la limite du raisonnable. Si cela est applicable,
l'influence d'une fonction sur les autres fonctions est prise en compte.
Lorsqu'une partie 2 ne comporte pas d'exigences complémentaires pour couvrir les dangers
traités dans la Partie 1, la Partie 1 s'applique.
NOTE 1 Cela signifie que les comités d'études responsables pour les parties 2 ont déterminé qu'il n'était pas
nécessaire de spécifier des exigences particulières pour l'appareil en question en plus des exigences générales.
Cette norme est une norme de famille de produits traitant de la sécurité d'appareils et a
préséance sur les normes horizontales et génériques couvrant le même sujet.
NOTE 2 Les publications horizontales, les publications fondamentales de sécurité et les publications groupées de
sécurité couvrant un danger ne s'appliquent pas, parce qu'elles ont été prises en considération lorsque les exigences
générales et particulières ont été étudiées pour la série de normes IEC 60335.
NOTE 3 Les normes traitant des aspects non relatifs à la sécurité des appareils électrodomestiques sont:
– les normes IEC publiées par le comité d'études 59 concernant les méthodes de mesure d'aptitude à la fonction;
– les normes CISPR 11 et CISPR 14-1, ainsi que les normes applicables de la série IEC 61000-3 concernant les
émissions électromagnétiques;
– la norme CISPR 14-2 concernant l'immunité électromagnétique;
– les normes IEC publiées par le comité d'études 111 concernant l'environnement.
Un appareil conforme au texte de la présente norme ne sera pas nécessairement jugé conforme
aux principes de sécurité de la norme si, lorsqu'il est examiné et soumis aux essais, il apparaît
qu'il présente d'autres caractéristiques qui compromettent le niveau de sécurité visé par ces
exigences.
1 Domaine d'application
L'article de la Partie 1 est remplacé par le texte suivant.
La présente partie de l'IEC 60335 traite de la sécurité des mobiliers avec des parties à
motorisation électrique pour usages domestiques et analogues, dont la tension assignée est
inférieure ou égale à 250 V, y compris les mobiliers alimentés en courant continu et les
mobiliers alimentés par batteries.
Les mobiliers incorporant des parties à motorisation électrique non destinés à un usage
domestique normal, mais qui peuvent néanmoins constituer une source de danger pour le
public, tels que les mobiliers destinés à être utilisés par des usagers non avertis dans des
magasins, bureaux, hôtels, restaurants, cinémas, hôpitaux, écoles, chez des artisans et dans
des fermes, sont compris dans le domaine d'application de la présente norme.
Exemples de mobiliers incorporant des parties à motorisation électrique:
– tables et bureaux à fonctionnement/réglage électrique de la hauteur;
– meubles et fixations murales à fonctionnement/réglage électrique, pour les postes de
télévision et les moniteurs, par exemple;
– siège à fonctionnement/réglage électrique;
– lits à ventilateurs et filtres incorporés;
– lits à fonctionnement/réglage électrique;
– unités de stockage à fonctionnement/réglage électrique, y compris les blocs cuisines;
– mobiliers à fonctionnement/réglage électrique destinés à être fixés au mur ou au plafond;
– éléments d'extension à fonctionnement électrique (tiroirs et portes);
– mobiliers à commande électrique dans les hôtels et les magasins;
– mobiliers livrés en pièces détachées (mobiliers prêts à assembler ou à monter).
La présente norme traite des dangers raisonnablement prévisibles que présente le mobilier
incorporant des parties à motorisation électrique pour toutes les personnes. Cependant, elle ne
tient en général pas compte:
– des personnes dont les capacités physiques, sensorielles ou mentales ou dont le manque
d'expérience ou de connaissance les empêchent d'utiliser le mobilier incorporant des
appareils, parties ou composants électriques en toute sécurité sans surveillance ou
instruction;
– de l'utilisation du mobilier incorporant des parties à motorisation électrique comme jouet
par des enfants.
Des exigences supplémentaires peuvent être nécessaires pour les mobiliers incorporant des
parties à motorisation électrique destinés à être utilisés dans des véhicules ou à bord de navires
ou d'avions. 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 la protection contre les
incendies et par des organismes similaires.
La présente norme ne s'applique pas:
– aux mobiliers comportant des éléments chauffants;
– aux mobiliers destinés à être utilisés dans des locaux qui présentent des conditions
particulières, telles que la présence d'une atmosphère corrosive ou explosive (poussière,
vapeur ou gaz);
– aux lits de massage et chaises de massage (IEC 60335-2-32);
– aux appareils électromédicaux (série IEC 60601);
– aux équipements des technologies de l'audio/vidéo, de l'information et de la communication
(IEC 62368-1);
– aux fauteuils roulants électriques;
– aux mobiliers particuliers incorporant des appareils, parties ou composants électriques,
faisant partie intégrante d'un matériel de production industrielle;
– aux articles électriques de puériculture, à l'exception des tables à langer (maternités)
réglables en hauteur;
– aux mobiliers spécialement destinés aux enfants;
– aux mobiliers utilisés à l'extérieur.
Les lits et chaises de massage comportant des parties motorisées, autres que celles qui
assurent la fonction de massage, sont également évalués conformément aux exigences
applicables de la présente norme.
Pour les besoins de la présente norme, le terme "appareil" utilisé ci-après doit être interprété
comme "mobilier avec des parties à motorisation-électrique".

Part 2-116: Particular requirements for furniture
with electrically motorized parts

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.

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.
Guidance documents concerning the application of the safety requirements for appliances can
be accessed via TC 61 supporting documents on the IEC website
https://www.iec.ch/tc61/supportingdocuments
This information is given for the convenience of users of this International Standard and does
not constitute a replacement for the normative text in this standard.
This standard only covers the risks associated with electrically motorized parts 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 such appliances. It does not cover
risks associated with furniture containing heating elements.
Other safety aspects of furniture with and without electrically motorized parts are covered by
the standards developed by ISO TC 136.
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 can 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 publications, basic safety publications and group safety publications 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.
NOTE 3 Standards dealing with non-safety aspects of household appliances are:
– IEC standards published by TC 59 concerning methods of measuring performance;
– CISPR 11, CISPR 14-1 and relevant IEC 61000-3 series standards concerning electromagnetic emissions;
– CISPR 14-2 concerning electromagnetic immunity;
– IEC standards published by TC 111 concerning environmental matters.
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.

1 Scope
This clause of Part 1 is replaced by the following.
This part of IEC 60335 deals with the safety of furniture with electrically motorized parts
intended for household and similar purposes, their rated voltage being not more than 250 V
including direct current (DC) supplied furniture and battery-operated furniture.
Furniture incorporating electrically motorized parts not intended for normal household use but
which nevertheless can be a source of danger to the public, such as furniture intended to be
used by laymen in shops, offices, hotels, restaurants, cinemas, hospitals, schools, in light
industry and on farms, are within the scope of this standard.
Examples of furniture incorporating electrically motorized parts, are
– electrically operated/height adjustable tables and desks;
– electrically operated/adjustable stands and wall attachment for e.g. TV sets and monitors;
– electrically operated/adjustable seating;
– beds with incorporated ventilators and filters;
– electrically operated/adjustable beds;
– electrically operated/adjustable storage units including kitchen units;
– electrically operated/adjustable furniture intended to be secured to the wall or ceiling;
– electrically operated extension elements (drawers and doors);
– electric check-out furniture in hotels and shops;
– furniture delivered in parts (ready to assemble or knock-down furniture).
This standard deals with the reasonably foreseeable hazards presented by furniture
incorporating electrically motorized parts that are encountered by all persons. However, in
general, it does not take into account
– persons whose physical, sensory or mental capabilities, or lack of experience and
knowledge prevents them from using the furniture incorporating electric appliances, parts
or components safely without supervision or instruction;
– children playing with furniture incorporating electrically motorized parts.
Additional requirements can be necessary for furniture incorporating electrically motorized
parts intended to be used in vehicles or on board ships or aircraft. In many countries, additional
requirements are specified by the national health authorities, the national authorities
responsible for the protection of labour, the national authorities for fire protection and similar
authorities.
This standard does not apply to:
– furniture containing heating elements;
– furniture intended to be used in locations where special conditions prevail, such as the
presence of a corrosive or explosive atmosphere (dust, vapour or gas);
– massage beds and massage chairs (IEC 60335-2-32);
– medical electrical equipment (IEC 60601 series);
– audio/video, information and communication technology equipment (IEC 62368-1);
– electrical wheel chairs;
– special furniture incorporating electric appliances, parts or components, which are part of
industrial production equipment;
– electric child care articles except electrical height adjustable changing (nursing) tables;
– furniture especially for use by children;
– furniture for outdoor use.
Massage beds and massage chairs with motorized parts, other than those performing the
massaging function, are also evaluated to the applicable requirements of this standard.
For the purpose of this standard, the term "appliance" from here and onward is to be read as
"furniture with electrically motorized parts".
