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).

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.

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.

– 8 – 60335-2-30 © IEC:2009(E)

9 Starting of motor-operated appliances
This clause of Part 1 is not applicable.
10 Power input and current
This clause of Part 1 is applicable.
11 Heating
This clause of Part 1 is applicable except as follows.
11.2 Replacement:
Heaters normally placed on the floor are placed in a test corner as follows:
– portable fan heaters are placed with the back 150 mm from one of the walls and away
from the other wall;
– other heaters are placed on the floor with their back as near to one of the walls as
possible and away from the other wall. However, circular and similar heaters that emit
heat in several directions are placed 300 mm from one of the walls and away from the
other wall. Heaters containing PTC heating elements are placed away from the walls if
this results in higher temperatures.
NOTE 101 If the back of the heater is not obvious, the heater is orientated in the most unfavourable position.
NOTE 102 For circular and similar heaters, the distance is measured between the wall and the enclosure of the
heater.
Fixed heaters are installed in the test corner as follows, unless otherwise specified in the
installation instructions:
– heaters for mounting at high level are fixed to one of the walls and as near as possible
to the other wall and ceiling;
– other heaters for wall mounting are fixed to one of the walls and as near as possible to the
other wall and floor. A shelf having a depth of 200 mm and of sufficient length to cover the
heater is fixed over the heater. It is positioned as close as possible to the heater;
– heaters for ceiling mounting are fixed to the ceiling as near as possible to the walls;
– heaters for mounting under benches are fixed to the ceiling of the test corner as near as
possible to the walls, the distance between the heater surface and the floor shall be as
stated in the instructions.
Built-in heaters are installed as close as possible to a floor or ceiling, unless otherwise
specified in the installation instructions.
Dull black-painted plywood approximately 20 mm thick is used for the test corner, the shelf
and for installation of built-in heaters.
The ceiling of the test corner is covered with insulating material having a coefficient of thermal
insulation of approximately 3,2 m K/W.
If a fixed heater has an opening at floor level, a felt pad 20 mm thick is placed on the floor
and pushed flat into the opening as far as the construction will permit. If a guard is provided
or if the opening is too small to permit the entry of the pad, the pad is pushed as close as
possible against the opening.
NOTE 103 The purpose of the felt pad is to simulate a carpet that might restrict the airflow.

60335-2-30 © IEC:2009(E) – 15 –
Heaters having an air-outlet grille intended to be recessed in a floor, a window-sill or similar
location are also tested with the air outlets covered with the felt strips specified in 19.103. The
strips are applied at right angles to the longest side of the outlet grilles. The strips are applied
to each half of the grille in turn and then to the complete grille.
For appliances provided with an automatic cord reel, one-third of the total length of the cord is
unreeled. The temperature rise of the cord sheath is determined as near as possible to the
hub of the reel and also between the two outermost layers of the cord on the reel.
For cord storage devices, other than automatic cord reels, that are intended to accommodate
the supply cord partially while the appliance is in operation, 50 cm of the cord is unwound.
The temperature rise of the stored part of the cord is determined at the most unfavourable
place.
Ceiling mounted heat lamp appliances that are recessed into a ceiling space or cavity are
installed in the test corner as follows, unless otherwise specified in the installation
instructions.
Recessed ceiling mounted heat lamp appliances are mounted as near as possible to the
walls in a test recess, consisting of the test corner ceiling, on top of which is a rectangular
box with vertical sides and horizontal top.
The test corner ceiling shall extend at least 100 mm outside the projection of the heater on
the ceiling. The box is made of dull black-painted plywood approximately 20 mm thick and the
top of the box is tightly sealed to its sides. The ceiling of the test corner external to the box
and the outside of the box is covered with insulating material having a coefficient of thermal
insulation of approximately 3,2 m K/W.
The position of the recessed ceiling mounted heat lamp appliances within the test box shall
be such that there is a space of 25 mm between the sides and top of the box and the top and
sides of the recessed parts of the heater.
11.3 Addition:
The temperature rise of the felt pad is determined by means of thermocouples attached to
small blackened disks of copper or brass, 15 mm in diameter and 1 mm thick. The disks are
placed on the surface of the pad.
11.4 Addition:
If the temperature rise limits are exceeded in appliances incorporating motors, transformers or
electronic circuits, and the power input is lower than the rated power input, the test is
repeated with the appliance supplied at 1,06 times rated voltage.
11.6 Replacement:
Combined appliances are operated as heating appliances.
11.7 Replacement:
Appliances are operated until steady conditions are established.
11.8 Addition:
In Table 3, stationary heaters are considered liable to be operated continuously for long
periods.
– 16 – 60335-2-30 © IEC:2009(E)
The temperature rise limits of motors, transformers and components of electronic circuits,
including parts directly influenced by them, may be exceeded when the appliance is operated
at 1,15 times rated power input.
For liquid-filled radiators, the temperature rise of parts in contact with oil is not measured.
However, for unvented liquid-filled radiators, the temperature rise of the outer surface of the
liquid container is measured. It shall be at least 50 K less than the boiling point of the liquid.
NOTE 101 The measurement is made even if the container is inside the enclosure of the appliance.
The temperature rise of surfaces of heaters shall not exceed the values shown in Table 101.

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.
– 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.

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.

This clause of Part 1 is not applicable.
10 Power input and current
This clause of Part 1 is applicable.
11 Heating
This clause of Part 1 is applicable except as follows.
11.2 Replacement:
Heaters normally placed on the floor are placed in a test corner as follows:
– portable fan heaters are placed with the back 150 mm from one of the walls and away
from the other wall;
– other heaters are placed on the floor with their back as near to one of the walls as
possible and away from the other wall. However, circular and similar heaters that emit
heat in several directions are placed 300 mm from one of the walls and away from the
other wall. Heaters containing PTC heating elements are placed away from the walls if
this results in higher temperatures.
NOTE 101 If the back of the heater is not obvious, the heater is orientated in the most unfavourable position.
NOTE 102 For circular and similar heaters, the distance is measured between the wall and the enclosure of the
heater.
Fixed heaters are installed in the test corner as follows, unless otherwise specified in the
installation instructions:
– heaters for mounting at high level are fixed to one of the walls and as near as possible
to the other wall and ceiling;
– other heaters for wall mounting are fixed to one of the walls and as near as possible to the
other wall and floor. A shelf having a depth of 200 mm and of sufficient length to cover the
heater is fixed over the heater. It is positioned as close as possible to the heater;
– heaters for ceiling mounting are fixed to the ceiling as near as possible to the walls;
– heaters for mounting under benches are fixed to the ceiling of the test corner as near as
possible to the walls, the distance between the heater surface and the floor shall be as
stated in the instructions.
Built-in heaters are installed as close as possible to a floor or ceiling, unless otherwise
specified in the installation instructions.
Dull black-painted plywood approximately 20 mm thick is used for the test corner, the shelf
and for installation of built-in heaters.
The ceiling of the test corner is covered with insulating material having a coefficient of thermal
insulation of approximately 3,2 m K/W.
If a fixed heater has an opening at floor level, a felt pad 20 mm thick is placed on the floor
and pushed flat into the opening as far as the construction will permit. If a guard is provided
or if the opening is too small to permit the entry of the pad, the pad is pushed as close as
possible against the opening.
NOTE 103 The purpose of the felt pad is to simulate a carpet that might restrict the airflow.

60335-2-30  IEC:2009 – 15 –
Heaters having an air-outlet grille intended to be recessed in a floor, a window-sill or similar
location are also tested with the air outlets covered with the felt strips specified in 19.103. The
strips are applied at right angles to the longest side of the outlet grilles. The strips are applied
to each half of the grille in turn and then to the complete grille.
For appliances provided with an automatic cord reel, one-third of the total length of the cord is
unreeled. The temperature rise of the cord sheath is determined as near as possible to the
hub of the reel and also between the two outermost layers of the cord on the reel.
For cord storage devices, other than automatic cord reels, that are intended to accommodate
the supply cord partially while the appliance is in operation, 50 cm of the cord is unwound.
The temperature rise of the stored part of the cord is determined at the most unfavourable
place.
Ceiling mounted heat lamp appliances that are recessed into a ceiling space or cavity are
installed in the test corner as follows, unless otherwise specified in the installation
instructions.
Recessed ceiling mounted heat lamp appliances are mounted as near as possible to the
walls in a test recess, consisting of the test corner ceiling, on top of which is a rectangular
box with vertical sides and horizontal top.
The test corner ceiling shall extend at least 100 mm outside the projection of the heater on
the ceiling. The box is made of dull black-painted plywood approximately 20 mm thick and the
top of the box is tightly sealed to its sides. The ceiling of the test corner external to the box
and the outside of the box is covered with insulating material having a coefficient of thermal
insulation of approximately 3,2 m K/W.
The position of the recessed ceiling mounted heat lamp appliances within the test box shall
be such that there is a space of 25 mm between the sides and top of the box and the top and
sides of the recessed parts of the heater.
11.3 Addition:
The temperature rise of the felt pad is determined by means of thermocouples attached to
small blackened disks of copper or brass, 15 mm in diameter and 1 mm thick. The disks are
placed on the surface of the pad.
11.4 Addition:
If the temperature rise limits are exceeded in appliances incorporating motors, transformers or
electronic circuits, and the power input is lower than the rated power input, the test is
repeated with the appliance supplied at 1,06 times rated voltage.
11.6 Replacement:
Combined appliances are operated as heating appliances.
11.7 Replacement:
Appliances are operated until steady conditions are established.
11.8 Addition:
In Table 3, stationary heaters are considered liable to be operated continuously for long
periods.

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.

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.
This consolidated version of the official IEC Standard and its amendments has been
prepared for user convenience.
IEC 60335-2-30 edition 5.2 contains the fifth edition (2009-11) [documents 61/3910/FDIS
and 61/3957/RVD] and its corrigendum 1 (2014-11), its amendment 1 (2016-11)
[documents 61/5281/FDIS and 61/5298/RVD] and its amendment 2 (2021-03) [documents
61/6130/FDIS and 61/6181/RVD].
In this Redline version, a vertical line in the margin shows where the technical content
is modified by amendments 1 and 2. Additions are in green text, deletions are in
strikethrough red text. A separate Final version with all changes accepted is available
in this publication.
+AMD2:2021 CSV  IEC 2021
International Standard IEC 60335-2-30 has been prepared by IEC technical committee 61:
Safety of household and similar electrical appliances.
This fifth edition 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).
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 stability 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.

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.

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 moving 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.

+AMD2:2021 CSV  IEC 2021
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);
