Part 2-30: Particular requirements for room heaters
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 60335-2-30 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, its Amendment 1
(2004) and Amendment 2 (2007). It constitutes a technical revision.The principal changes in this edition as compared with the fourth edition of IEC 60335-2-30
are as follows (minor changes are not listed):– some additional instructions are introduced for heaters without a built-in thermostat, or
those installed in the floor or in a bathroom (7.12 and 7.12.1);– a spillage test is introduced for appliances having a grille and that are built into the floor
(15.2).This bilingual version (2012-09) corresponds to the monolingual English version, published in
2009-11.---------------------- Page: 5 ----------------------
– 4 – 60335-2-30 IEC:2009
The text of this standard is based on the following documents:
FDIS Report on voting
61/3910/FDIS 61/3957/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.The French version of this standard has not been voted upon.
This publication 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 fourth edition (2001) 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 room heaters.
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 the base publication and its amendments will
remain unchanged until the maintenance result date indicated on the IEC web site under
"http://webstore.iec.ch" in the data related to the specific publication. At this date, the
publication 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 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.---------------------- Page: 8 ----------------------

HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
SAFETY –
Part 2-30: Particular requirements for room heaters
1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electric room heaters for household and
similar purposes, their rated voltage being not more than 250 V for single-phase appliances
and 480 V for other appliances.NOTE 101 Examples of appliances that are within the scope of this standard are
– convector heaters;
– fan heaters;
– heaters for use in greenhouses;
– liquid-filled radiators;
– panel heaters;
– radiant heaters;
– tubular heaters;
– ceiling mounted heat lamp appliances.
For extraction fans of ceiling mounted heat lamp appliances, IEC 60335-2-80 is applicable
as far as is reasonable.Appliances not intended for normal household use but which nevertheless may be a source of
danger to the public, such as appliances intended to be used by laymen in the 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 which 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.NOTE 102 Attention is drawn to the fact that
– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may 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;– for appliances intended to be used in the presence of combustible dust, for example in barns or stables,
additional requirements may be necessary.---------------------- Page: 9 ----------------------
– 8 – 60335-2-30 IEC:2009
NOTE 103 This standard does not apply to
– appliances intended exclusively for industrial purposes;
– appliances intended to be used where special conditions prevail, such as the presence of a corrosive or
explosive atmosphere (dust, vapour or gas);– heaters that are built into air conditioners (IEC 60335-2-40);
– clothes dryers and towel rails (IEC 60335-2-43);
– heaters for saunas (IEC 60335-2-53);
– thermal-storage room heaters (IEC 60335-2-61);
– heating appliances for breeding and rearing animals (IEC 60335-2-71);
– foot warmers and heating mats (IEC 60335-2-81);
– flexible sheet heating elements for room heating (IEC 60335-2-96);
– heated carpets;
– central heating systems;
– heating cables (IEC 60800).
