Part 2-106: Particular requirements for heated carpets and for heating
units for room heating installed under removable floor coverings
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.

IEC 60335-2-106 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 2007. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
a) the text has been aligned with IEC 60335-1:2020;

b) some notes have been converted to normative text (Clause 1, 5.2, 5.3, 5.6, 7.12.1, 7.101,

10.1, 18.101.1, 18.101.2, 18.102.5, 19.1, 19.103, 21.1, 21.104, 21.105, 30.102);

c) requirements for portable heated carpets have been added (Clause 1, 5.2, 5.5, 6.1, 6.2, 7.1,

7.6, 7.12, 7.14, 7.101, 11.8, 15.1, 15.101, 16.1, 16.2, 16.3, 19.101, 19.102. 19.103, 21.105,

21.106, 24.1.5, 24.2, 29.3);
---------------------- Page: 6 ----------------------
IEC 60335-2-106:2021 © IEC 2021 – 5 –

d) requirements for washable portable heated carpets have been added (5.3, 7.1, 7.6, 7.12,

7.14);
e) the test of 30.102 has been updated.
The text of this International Standard is based on the following documents:
Draft Report on voting
61/6369/FDIS 61/6419/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/standardsdev/publications.

A list of all parts in the IEC 60335 series, published 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 heated carpets and for

heating units for room heating installed under removable floor coverings.

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.

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 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 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.

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.
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.

Part 2-106: Particular requirements for heated carpets and for heating
units for room heating installed under removable floor coverings
1 Scope
This clause of Part 1 is replaced by the following.
This part of IEC 60335 deals with the safety of
– portable heated carpets;
– heated carpets and similar appliances;

– heating units to heat the room in which they are located and that are intended to be installed

directly under materials used as a removable floor covering such as carpet, cushion vinyl,

or loose laid laminate,

their rated voltage being not more than 250 V for single-phase installations and 480 V for other

installations, including direct current (DC) supplied appliances.
Attention is drawn to the fact that
– in many countries different wiring rules apply;

– 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 authorities for fire

protection, the national authorities for building regulations, 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);
– blankets, pads and similar flexible heating appliances (IEC 60335-2-17);

– heated mats and foot warmers with an area not exceeding 0,5 m (IEC 60335-2-81);
