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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 part of International Standard IEC 60335 has been prepared by IEC Technical Committee 61:
Safety of household and similar electrical appliances.
This consolidated version of IEC 60335-2-102 consists of the first edition (2004) [documents
61/2532/FDIS and 61/2576/RVD] and its amendment 1 (2008) [documents 61/3695/FDIS and
61/3749/RVD].
The technical content is therefore identical to the base edition and its amendment and has
been prepared for user convenience.
It bears the edition number 1.1.
A vertical line in the margin shows where the base publication has been modified by
amendment 1.
– 4 – 60335-2-102 © IEC:2004+A1:2008

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 and

its Amendment 1.
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 gas, oil and solid-fuel

burning appliances having electrical connections.

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 the amendment 1 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.

SAFETY –
Part 2-102: Particular requirements for gas, oil and solid-fuel

burning appliances having electrical connections

1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of gas, oil and solid-fuel burning appliances
having electrical connections, for household and similar purposes, their rated voltage being
not more than 250 V for single-phase appliances and 480 V for other appliances.
This standard covers the electrical safety and some other safety aspects of these appliances.
All safety aspects are covered when the appliance also complies with the relevant standard
for the fuel-burning appliance. If the appliance incorporates electric heating sources, it also
has to comply with the relevant part 2 of IEC 60335.
NOTE 101 Examples of appliances within the scope of this standard are
– central heating boilers;
– commercial catering equipment;
– cooking appliances;
– laundry and cleaning appliances;
– room heaters;
– warm air heaters;
– water heaters.
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 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 that 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.
NOTE 103 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).

15.2 Addition:
For cooking ranges, hobs and similar appliances, compliance is checked by the following
tests.
– 10 – 60335-2-102 © IEC:2004+A1:2008

Cooking ranges and hobs are positioned so that the hob surface is horizontal, detachable

burner heads being in position. A vessel having a diameter approximately 220 mm is

completely filled with water containing approximately 1 % NaCl and positioned centrally over

the burner. A further quantity of 0,5 l of the solution is poured steadily into the vessel over a

period of 15 s.
This test is made for each burner separately, after removing any residual solution from the

appliance.
If controls are mounted below the hob surface, 0,5 l of the saline solution is poured steadily

over the top of the hob near the controls over a period of 15 s. If they are mounted in the hob

surface, the solution is poured over the controls.
For burners incorporating a temperature sensor, switch or ignition device, 0,02 l of the saline
solution is poured over the burner so that it flows over the device.
For ovens or grills, 0,5 l of the saline solution is poured over the floor of the oven or grilling
compartment.
For appliances having a drip tray or similar receptacle, the receptacle is filled with the saline
solution. A further quantity of the solution, equal to 0,01 l per 100 cm² of the area of the top
surface of the receptacle, is poured onto the receptacle through openings in the hob surface.
However, the total quantity of solution shall not exceed 3 l.
For hobs provided with a lid, 0,5 l of the saline solution is poured uniformly over the closed lid.
When the solution has run off, the surface is dried and a further 0,125 l of the solution is
poured steadily from a height of approximately 50 mm onto the centre of the lid over a period
of 15 s. The lid is then opened as in normal use.
16 Leakage current and electric strength
This clause of Part 1 is applicable except as follows.
16.2 Modification:
The limit for stationary class I motor-operated appliances is applicable.
16.3 Addition:
The no-load peak voltage of spark-ignition circuits is measured with the spark electrode

removed. The peak voltage applied between the spark-ignition circuit and metal foil
covering the insulation is 1,5 times this value.
NOTE 101 It may be necessary to insulate the spark gap to prevent it flashing over during the test.
17 Overload protection of transformers and associated circuits
This clause of Part 1 is applicable.
18 Endurance
This clause of Part 1 is not applicable.

60335-2-102 © IEC:2004+A1:2008 – 11 –

19 Abnormal operation
This clause of Part 1 is applicable except as follows.

19.4 Addition:
The test is repeated with the supply neutral conductor connected to the protective conductor,

however any controls are not short-circuited.

This test is repeated with the polarity of the supply to the appliance reversed and with the

neutral conductor connected to the protective conductor.

The additional tests are not carried out on appliances where an all-pole disconnection is
used to disconnect all fuel valves.
19.11.2 Addition:
For risks concerning the fuel, in each case the test is ended if a shut-down is performed.
NOTE 101 Mechanical blocking of the fuel valves is not a failure to be considered for the verification of this
requirement but the mechanical or electrical blocking of the acting member (power switching device or relay-
contact) of the fuel control have to be considered as one possible fault under this requirement.
19.11.4 Addition:
The tests of 19.11.4.1 to 19.11.4.7 are also carried out under normal operation, the
appliance being supplied at rated voltage.
19.13 Addition:
During and after the tests of 19.11.4, the appliance shall have reached a lock-out condition,
unless it continues to operate normally.
NOTE 101 Lock-out may be reached after a number of shut-down operations.
20 Stability and mechanical hazards
This clause of Part 1 is applicable except as follows.
20.1 Not applicable.
21 Mechanical strength
This clause of Part 1 is applicable except as follows.
21.1 Modification:
The blows are only applied to enclosures of live parts and enclosures of dangerous moving
parts.
22 Construction
This clause of Part 1 is applicable except as follows.

22.101 Parts of spark-ignition circuits shall be positioned or secured against loosening so

that contact between the circuit and other live parts is prevented.

Compliance is checked by inspection and by applying a force of approximately 5 N to the

wiring.
22.102 If compliance with this standard can be affected by the polarity of the supply in the

event of an earth fault, the appliance shall incorporate a polarity-detection device that results

in shut-down or prevents the appliance from operating if the polarity is reversed.

This requirement does not apply to appliances incorporating a control having all-pole

disconnection, to appliances intended to be permanently connected to fixed wiring, or to
appliances having a supply cord fitted with a polarized plug.
NOTE This requirement avoids the uncontrolled opening of a gas valve in the event of an earth fault.
Compliance is checked by inspection.
22.103 If the limits in 8.101 are exceeded, the insulation of the parts of the circuit, where
distances to unearthed accessible conductive parts do not comply with reinforced insulation
according to 29.1 and 29.2, shall be resistant to ageing caused by partial discharge due to the
ignition sparks. This requirement is not applicable to the insulation of cables having electrical
properties complying with ISO 3808.
Compliance is checked by carrying out the following aging test.
The spark-ignition circuits are operated for at least 100 h under the following test
specification:
– maximum duration of ignition switch-on repeated for the appropriate number of cycles in
order to obtain the total test time (any rest period applied to avoid overheating the
transformer or as a result of the normal operation of the ignition circuit is not taken into
account when measuring the total test time);
– maximum value of the spark ignition voltage measured when the appliance is supplied at
rated voltage;
– the temperature of the insulation as measured under the conditions of Clause 11.
There shall be no breakdown of the insulation. In case of doubt, the test of 16.3 is applied
between the cable conductor and water with the cable insulation immersed in water.
NOTE Care should be taken to avoid overheating of the ignition transformer.

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (CEI) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de la CEI). La CEI a
pour objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les
domaines de l'électricité et de l'électronique. A cet effet, la CEI – 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 la CEI"). 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 la CEI, participent
également aux travaux. La CEI 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 la CEI concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de la CEI
intéressés sont représentés dans chaque comité d’études.
3) Les Publications de la CEI se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de la CEI. Tous les efforts raisonnables sont entrepris afin que la CEI
s'assure de l'exactitude du contenu technique de ses publications; la CEI 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 la CEI s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de la CEI dans leurs publications
nationales et régionales. Toutes divergences entre toutes Publications de la CEI et toutes publications
nationales ou régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) La CEI n’a prévu aucune procédure de marquage valant indication d’approbation et n'engage pas sa
responsabilité pour les équipements déclarés conformes à une de ses Publications.
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 la CEI, à ses administrateurs, employés, auxiliaires ou
mandataires, y compris ses experts particuliers et les membres de ses comités d'études et des
