FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The 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 subcommittee 61D:
Appliances for air-conditioning for household and similar purposes, of IEC technical
committee 61: Safety of household and similar electrical appliances.

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.
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.
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.
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.

air-conditioners and dehumidifiers
1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electric heat pumps, including sanitary
hot water heat pumps, air-conditioners, and dehumidifiers incorporating sealed motor-
compressors, their maximum rated voltages being not more than 250 V for single phase
appliances and 600 V for all other appliances.
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.
The appliances referenced above may consist of one or more factory made assemblies. If
provided in more than one assembly, the separate assemblies are to be used together, and
the requirements are based on the use of matched assemblies.
NOTE 101 A definition of "sealed motor-compressor" is given in IEC 60335-2-34.
NOTE 102 Requirements for refrigeration safety are covered by ISO 5149, and requirements for containers
intended for storage of the heated water included in sanitary hot water heat pumps are, in addition, covered by
IEC 60335-2-21.
NOTE 103 For appliances using flammable refrigerants, additional requirements are under consideration.
Supplementary heaters, or a provision for their separate installation, are within the scope of
this standard, but only heaters which are designed as a part of the appliance package, the
controls being incorporated in the appliance.
NOTE 104 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;
– for appliances subjected to pressure, 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, the national water supply authorities and similar authorities.
In the case of appliances for permanent connection to the water supply system, all relevant requirements need
to be observed.
NOTE 105 This standard does not apply to
– humidifiers intended for use with heating and cooling equipment (IEC 60335-2-88);
– appliances designed exclusively for industrial processing;
– 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).

60335-2-40 © IEC:2002(E) – 13 –
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 replaced by the following.
11.1 Appliances and their surroundings shall not attain excessive temperatures in normal use.
Compliance is checked by determining the temperatures of the various parts under the
conditions specified in 11.2 to 11.7. Nevertheless, if the temperature of the motor winding
exceeds the value specified in Table 3 or if there is doubt with regard to the classification of
the insulation system employed in a motor, compliance is checked by the tests of Annex C.
11.2 Appliances are installed in a test room in accordance with the manufacturer's
installation instructions. In particular
– clearances to adjacent surfaces specified by the manufacturer shall be maintained;
– flow rates for liquid source or sink equipment shall be the minimum specified in the
manufacturer's instructions;
– the outlet duct connected to the appliance shall be subjected to the maximum static
pressure given in the manufacturer's instructions;
– for appliances provided with means of adjusting the flow, the flow for the tests shall be the
minimum obtainable;
– adjustable limit controls are set at the maximum cutout setting and the minimum
differential permitted by the control adjusting means.
For appliances provided with supplementary heaters, an additional test casing as described
in 11.9 is used.
11.2.1 For heating tests of appliances with supplementary heaters, an inlet duct is
connected to the inlet air opening of the appliance (assuming that the appliance is intended to
be so applied). The duct shall be the same size as the flanges, if flanges are provided. If
flanges are not provided, the duct is the same size as the inlet opening.
The inlet duct is provided with an adjustable restricting means by which the airflow can be
reduced.
The restriction should be uniform across the duct's cross sectional area, so that the full
heating coil surface will be exposed to the airflow except when the restriction is closed.
11.2.2 An appliance which does not include supplementary heaters is fitted with an outlet
duct sized to fit the casing flanges, or opening without flanges, or locations marked for
flanges, and arranged to discharge away from the return air inlet.
An appliance that includes or has provision for supplementary heater is fitted with a metal
outlet duct in accordance with Figure 101a) or Figure 101b), depending on the direction of the
airflow.
– 14 – 60335-2-40 IEC:2002(E)
The outlet duct is provided with a restricting means to obtain the maximum static pressure
given in the manufacturer's instructions.
11.3 Temperatures other than those of windings are determined by means of fine-wire
thermocouples so chosen and positioned that they have the minimum effect on the
temperature of the part under test.
NOTE 101 Thermocouples having wires with a diameter not exceeding 0,3 mm are considered to be fine-wire
thermocouples.
Thermocouples used for determining the temperatures of the surface of walls, ceiling and
floor are embedded in the surface or attached to the back of small blackened disks of copper
or brass, 15 mm in diameter and 1 mm thick, which are flush with the surface.
So far as is possible, the appliance is positioned so that parts likely to attain the highest
temperatures touch the disks.
In determining the temperatures of handles, knobs, grips and the like, consideration is given
to all parts which are gripped in normal use and, if of insulating material, to parts in contact
with hot metal.
The temperature of electrical insulation, other than that of windings, is determined on the
surface of the insulation, at places where failure could cause a short circuit, contact between
live parts and accessible metal parts, bridging of insulation or reduction of clearances and
creepage distances below the values specified in Clause 29.
Temperatures of windings are determined by the resistance method unless the windings are
non-uniform or severe complications are involved in order to make the necessary
connections, in which case the temperatures are determined by means of thermocouples.
The temperatures in the duct are to be measured by means of a thermocouple grid consisting
of nine thermocouples of identical length, wired in parallel to form a grid with a thermocouple
located centrally in each of nine equal duct areas in a plane perpendicular to the axis of the
airflow.
11.4 Appliances are operated under normal operation at a supply voltage between
0,94 times the lowest rated voltage and 1,06 times the highest rated voltage, the voltage
chosen being that which gives the most unfavourable result. Heating elements shall be
energized at a voltage which gives an electrical input of 1,15 times the maximum rated power
input.
11.5 Where appliance can be operated in the cooling mode as well as the heating mode, a
test is conducted in each mode.
For appliances with supplementary heaters or provision for supplementary heaters, in
additional test is conducted with all the heating elements operative by short circuiting
thermostats or by reducing, if necessary, the air temperature to a value which causes all the
elements to switch on.
11.6 Appliances with defrost facilities, are additionally submitted for a defrost test in the
most unfavourable conditions.
11.7 All appliances are operated continuously until steady conditions are achieved except
for defrost tests.
11.8 During the test the temperatures are monitored continuously and shall not exceed the

60335-2-40 © IEC:2002(E) – 15 –
The temperature of the air in the outlet duct shall not exceed 90 °C.
NOTE 101 The value of the temperature of a winding is calculated from the formula:
R
T = ()k + T − k
R
where:
T is the temperature of the copper winding at the end of the test
R is the resistance at the beginning of the test
R is the resistance at the end of the test
T is the ambient temperature at the beginning of the test
k is equal to 234,5 for copper windings and 225 for aluminium windings.
At the beginning of the test, the windings shall be at ambient temperature.
It is recommended that the resistance of windings at the end of the test be determined by taking resistance
measurements as soon as possible after switching off, and then at short intervals so that a curve of resistance
against time can be plotted for ascertaining the resistance at the instant of switching off.

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.

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.
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.
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.
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.

HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
SAFETY –
Part 2-40: Particular requirements for electrical heat pumps,
air-conditioners and dehumidifiers
1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electric heat pumps, including sanitary
hot water heat pumps, air-conditioners, and dehumidifiers incorporating motor-
compressors and hydronic room fan coils, their maximum rated voltages being not more
than 250 V for single phase appliances and 600 V for all other appliances.
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.
This standard also applies to electric heat pumps, air conditioners and dehumidifiers
containing flammable refrigerant. Flammable refrigerants are defined in 3.120.
The appliances referenced above may consist of one or more factory made assemblies. If
provided in more than one assembly, the separate assemblies are to be used together, and
the requirements are based on the use of matched assemblies.
NOTE 101 A definition of ‘motor-compressor’ is given in IEC60335-2-34, which includes the statement that the
term motor-compressor is be used to designate either a hermetic motor-compressor or semi-hermetic motor-
compressor.
NOTE 102 Requirements for refrigeration safety are covered by ISO 5149, and requirements for containers
intended for storage of the heated water included in sanitary hot water heat pumps are, in addition, covered by
IEC 60335-2-21.
This standard does not take into account chemicals other than group A1, A2, or A3 as defined
by 3.121.
NOTE 103 This standard specifies particular requirements for the use of flammable refrigerants. Unless
specifications are covered by this standard, including the annexes, requirements for refrigerating safety are
covered by ISO 5149.
The sections and clauses in ISO 5149 of particular concern to this standard are as follows:
– Section 3: Design and construction of equipment applies to all appliances and systems.
– Section 4: Requirements for utilization applies to appliances and systems which are for “similar electrical
appliances”, i.e. commercial and light industrial.
– Section 5: Operating procedures applies to appliances and systems which are for “similar electrical appliances”,
i.e. commercial and light industrial.
Supplementary heaters, or a provision for their separate installation, are within the scope of
this standard, but only heaters which are designed as a part of the appliance package, the
controls being incorporated in the appliance.
NOTE 104 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;
– for appliances subjected to pressure, additional requirements may be necessary;
– in many countries additional requirements are specified, for example, by the national health authorities
responsible for the protection of labour and the national authorities responsible for storage, transportation,
building constructions and installations.
– 8 – 60335-2-40 IEC:2002+A1:2005

NOTE 105 This standard does not apply to
– humidifiers intended for use with heating and cooling equipment (IEC 60335-2-88);
– appliances designed exclusively for industrial processing;
– 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).

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 subcommittee 61D:
Appliances for air-conditioning for household and similar purposes, of IEC technical
committee 61: Safety of household and similar electrical appliances.
This fourth edition cancels and replaces the third edition published in 1995 and its
amendment 1 (2000). It constitutes a technical revision.

INTRODUCTION
Il a été considéré en établissant la présente norme internationale que l'exécution de ses dis-
positions était confiée à des personnes expérimentées et ayant une qualification appropriée.
Cette norme reconnaît le niveau de protection internationalement accepté contre les risques
électriques, mécaniques, thermiques, liés au feu et au rayonnement des appareils, lorsqu'ils
fonctionnent comme en usage normal en tenant compte des instructions du fabricant. Elle
couvre également les situations anormales auxquelles on peut s'attendre dans la pratique.
Cette norme tient compte autant que possible des exigences de la CEI 60364, de façon à
rester compatible avec les règles d'installation quand l’appareil est raccordé au réseau
d’alimentation. Cependant, des règles nationales d'installation peuvent être différentes.
Si un appareil compris dans le domaine d’application de cette norme comporte également des
fonctions qui sont couvertes par une autre partie 2 de la CEI 60335, la partie 2
correspondante est appliquée à chaque fonction séparément, dans la limite du raisonnable. Si
cela est applicable, on tient compte de l’influence d’une fonction sur les autres fonctions.
Cette norme est une norme de famille de produits traitant de la sécurité d’appareils et a
préséance sur les normes horizontales et génériques couvrant le même sujet.
Un appareil conforme au texte de la présente norme ne sera pas nécessairement jugé
conforme aux principes de sécurité de la norme si, lorsqu'il est examiné et soumis aux essais,
il apparaît qu'il présente d'autres caractéristiques qui compromettent le niveau de sécurité
visé par ces exigences.
Un appareil utilisant des matériaux ou présentant des modes de construction différents de
ceux décrits dans les exigences de cette norme peut être examiné et essayé en fonction de
l'objectif poursuivi par ces exigences et, s'il est jugé pratiquement équivalent, il peut être
estimé conforme aux principes de sécurité de la norme.
60335-2-40 IEC:2006 – 11 –
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.
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.
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.
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.

1 Domaine d’application
L’article de la Partie 1 est remplacé par l’article ci-après.
La présente Norme internationale traite de la sécurité des pompes à chaleur électriques, y
compris les pompes à chaleur pour l’eau chaude sanitaire, les climatiseurs et les
déshumidificateurs qui comportent des moto-compresseurs hermétiques et des ventilo-
convecteurs hydroniques, dont la tension assignée maximale n'est pas supérieure à 250 V
pour les appareils monophasés et à 600 V pour tous les autres appareils.
Les appareils qui ne sont pas destinés à un usage domestique normal mais qui peuvent
néanmoins constituer une source de danger pour le public, tels que les appareils destinés à
être utilisés par des usagers non avertis dans des magasins, chez des artisans et dans des
fermes, sont compris dans le domaine d'application de la présente norme.
Les appareils indiqués ci-dessus peuvent consister en une ou plusieurs parties assemblées
en usine. S’ils sont livrés en plus d’une partie, les différentes parties doivent être utilisées
ensemble et les exigences sont basées sur l’utilisation de ces parties assemblées.
NOTE 101 Une définition du terme « moto-compresseur hermétique » se trouve dans la CEI 60335-2-34.
NOTE 102 Des exigences pour la sécurité frigorifique sont données par l’ISO 5149, et les exigences pour les
réservoirs destinés au stockage de l’eau chaude compris dans les pompes à chaleur pour l’eau chaude sanitaire
sont, en outre, couvertes par la CEI 60335-2-21.
NOTE 103 Des exigences supplémentaires sont à l’étude pour les appareils utilisant des fluides frigorigènes
inflammables.
Les dispositifs de chauffage supplémentaires ou les dispositions nécessaires à leur
installation sont couverts par le domaine d’application de la présente norme, mais uniquement
pour les dispositifs de chauffage qui sont conçus en tant que partie de l’appareil, les
dispositifs de commande étant incorporés dans l’appareil.
NOTE 104 L’attention est attirée sur le fait que
– pour les appareils destinés à être utilisés dans des véhicules ou à bord de navires ou d'avions, des exigences
supplémentaires peuvent être nécessaires;

Part 2-40: Particular requirements for electrical heat pumps,
air-conditioners and dehumidifiers
1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electric heat pumps, including sanitary
hot water heat pumps, air-conditioners, and dehumidifiers incorporating sealed motor-
compressors, their maximum rated voltages being not more than 250 V for single phase
appliances and 600 V for all other appliances.
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.
The appliances referenced above may consist of one or more factory made assemblies. If
provided in more than one assembly, the separate assemblies are to be used together, and
the requirements are based on the use of matched assemblies.
NOTE 101 A definition of "sealed motor-compressor" is given in IEC 60335-2-34.
NOTE 102 Requirements for refrigeration safety are covered by ISO 5149, and requirements for containers
intended for storage of the heated water included in sanitary hot water heat pumps are, in addition, covered by
IEC 60335-2-21.
NOTE 103 For appliances using flammable refrigerants, additional requirements are under consideration.
Supplementary heaters, or a provision for their separate installation, are within the scope of
this standard, but only heaters which are designed as a part of the appliance package, the
controls being incorporated in the appliance.
NOTE 104 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;
– for appliances subjected to pressure, 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, the national water supply authorities and similar authorities.
In the case of appliances for permanent connection to the water supply system, all relevant requirements need
to be observed.
NOTE 105 This standard does not apply to
– humidifiers intended for use with heating and cooling equipment (IEC 60335-2-88);
– appliances designed exclusively for industrial processing;
– 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).

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

Part 2-40: Particular requirements for electrical heat pumps,
air-conditioners and dehumidifiers
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 subcommittee 61D:
Appliances for air-conditioning for household and similar purposes, of IEC technical
committee 61: Safety of household and similar electrical appliances.
This consolidated version of IEC 60335-2-40 consists of the fourth edition (2002) [documents
61D/116/FDIS and 61D/121/RVD], its amendment 1 (2005) [documents 61D/138/FDIS
and 61D/140/RVD], its corrigendum 1 of May 2006 and its amendment 2 (2005) [documents
61D/136C/FDIS and 61D/142/RVD].
The technical content is therefore identical to the base edition and its amendments and has
been prepared for user convenience.
It bears the edition number 4.2.

INTRODUCTION
Il a été considéré en établissant la présente norme internationale que l'exécution de ses dis-
positions était confiée à des personnes expérimentées et ayant une qualification appropriée.
Cette norme reconnaît le niveau de protection internationalement accepté contre les risques
électriques, mécaniques, thermiques, liés au feu et au rayonnement des appareils, lorsqu'ils
fonctionnent comme en usage normal en tenant compte des instructions du fabricant. Elle
couvre également les situations anormales auxquelles on peut s'attendre dans la pratique.
Cette norme tient compte autant que possible des exigences de la CEI 60364, de façon à
rester compatible avec les règles d'installation quand l’appareil est raccordé au réseau
d’alimentation. Cependant, des règles nationales d'installation peuvent être différentes.
Si un appareil compris dans le domaine d’application de cette norme comporte également des
fonctions qui sont couvertes par une autre partie 2 de la CEI 60335, la partie 2
correspondante est appliquée à chaque fonction séparément, dans la limite du raisonnable. Si
cela est applicable, on tient compte de l’influence d’une fonction sur les autres fonctions.
Cette norme est une norme de famille de produits traitant de la sécurité d’appareils et a
préséance sur les normes horizontales et génériques couvrant le même sujet.
Un appareil conforme au texte de la présente norme ne sera pas nécessairement jugé
conforme aux principes de sécurité de la norme si, lorsqu'il est examiné et soumis aux essais,
il apparaît qu'il présente d'autres caractéristiques qui compromettent le niveau de sécurité
visé par ces exigences.
Un appareil utilisant des matériaux ou présentant des modes de construction différents de
ceux décrits dans les exigences de cette norme peut être examiné et essayé en fonction de
l'objectif poursuivi par ces exigences et, s'il est jugé pratiquement équivalent, il peut être
estimé conforme aux principes de sécurité de la norme.

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.
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.
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.
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.
