Household and similar electrical appliances - Safety - Part 2-116: Particular requirements for furniture with electrically motorized parts

IEC 60335-2-116:2019 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.
Furniture incorporating electrically motorised parts not intended for normal household use but which nevertheless may 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 motorised 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 motorised 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 motorised parts.
Attention is drawn to the fact that
– for furniture incorporating electrically motorised parts 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, the national authorities for fire protection and similar authorities.
This standard does not apply to
– furniture containing heating elements;
– electrically operated hospital beds (IEC 60601-2-52);
– electrical wheel chairs;
– special furniture incorporating electric appliances, parts or components, which are part of industrial production equipment;
– cupboards for building in appliances like a dishwasher;
– electric child care articles except electrical height adjustable changing (nursing) tables;
– furniture especially for use by children;
– furniture for outdoor use.
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 motorised parts are covered by the standards developed by ISO TC 136.
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.

Appareils électrodomestiques et analogues - Sécurité - Partie 2-116: Exigences particulières pour les meubles avec des parties électriquement motorisées

L'IEC 60335-2-116:2019 traite de la sécurité du mobilier avec des parties électriquement motorisées, pour usages domestiques et analogues, dont la tension assignée n'est pas supérieure à 250 V.
Les mobiliers intégrant des parties à motorisation électrique non destinés à un usage domestique normal, mais qui néanmoins peuvent constituer une source de danger pour le public (le mobilier destiné à être utilisé par des usagers non avertis dans des magasins, des bureaux, des hôtels, des restaurants, des cinémas, des hôpitaux, des écoles, chez les artisans et dans des fermes, par exemple) sont compris dans le domaine d'application de la présente norme.
Exemples de mobilier intégrant des parties à motorisation électrique:
– tables et bureaux à fonctionnement/réglage de la hauteur électrique;
– meubles et fixations murales à fonctionnement/réglage électrique, pour les postes de télévision et les moniteurs, par exemple;

– éléments d'extension à fonctionnement électrique (tiroirs et portes);
– mobilier à commande électrique dans les hôtels et les magasins;
– mobilier livré en pièces détachées (mobilier prêt à assembler ou monter).
La présente norme traite des dangers raisonnablement prévisibles que présente le mobilier incorporant des parties à motorisation électrique pour toutes les personnes. Cependant, la présente norme ne tient pas compte en général:
– 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.
L'attention est attirée sur le fait que:
– pour le mobilier incorporant des parties à motorisation électrique destiné à être utilisé 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 la protection contre les incendies et par des organismes similaires.
La présente norme ne s'applique pas:
– au mobilier comprenant des éléments chauffants;
– aux lits d'hôpital électriques (IEC 60601-2-52);
– aux fauteuils roulants électriques;
– au mobilier particulier intégrant des appareils, parties ou composants électriques, faisant partie intégrante d'un matériel de production industrielle;
– aux armoires pour appareils encastrés (les lave-vaisselle, par exemple);
– aux articles électriques de puériculture, à l'exception des tables à langer (maternités) réglables en hauteur;
– au mobilier spécialement destiné aux enfants;
– au mobilier utilisé à l'extérieur.
La présente norme couvre uniquement les risques liés aux parties électriquement motorisées lorsqu'elles fonctionnent comme en usage normal en tenant compte des instructions du fabricant. Elle couvre également les situations anormales qui peuvent être attendues dans la pratique et prend en considération les phénomènes électromagnétiques qui peuvent affecter le fonctionnement en toute sécurité de tels appareils. Elle ne couvre pas les risques liés au mobilier comprenant des éléments chauffants.
D'autres aspects relatifs à la sécurité du mobilier avec et sans parties électriquement motorisées sont couverts par les normes élaborées par le TC 136 de l'ISO.
La présente partie 2 doit être utilisée conjointement avec la dernière édition de l'IEC 60335-1 et ses a

Part 2-116: Particular requirements for furniture
with electrically motorised 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.

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 60335-2-116 has been prepared by IEC technical committee 61:

Safety of household and similar electrical appliances.

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. 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 furniture with

electrically motorised 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 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.

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 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 motorised 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 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.
