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.
It forms the first edition of IEC 60335-2-104.
The text of this part of IEC 60335 is based on the following documents:

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.

11.3 Temperatures 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.
The temperature of motor windings or of coils may be measured by the change-in-resistance
method.
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

For totally enclosed motors, the temperature limits for Class A, Class E and Class B materials may be

increased by 5°C (5 K).
A totally enclosed motor is a motor so constructed that the circulation of the air between the inside and the

outside of the case is prevented, but which is not necessarily sufficiently enclosed to be called airtight.

d)
T means the maximum operating temperature. The ambient of switches and thermostats is the temperature

of the air at the hottest point at a distance of 5 mm from the surface of the switch and thermostat concerned.

For the purpose of this test, switches and thermostats marked with the individual ratings may be considered
as having no marking for the maximum operating temperature, if this is requested by the manufacturer of the

appliance.
e)
This limit applies to cables, cords and wires complying with the relevant IEC standards; for others it may be

different.
f)
There is no specific limit for thermoplastic material, which must withstand the tests of 30.1 or 30.2 of Part 1,
for which purpose the temperature shall be measured.
g)
The limit specified concerns the deterioration of wood and it does not take into account the deterioration of
surface finishes.
h)
There is no limit for the temperature rise of capacitors which are short-circuited in 19.7.
i)
Temperature marking for capacitors mounted on printed circuit boards may be given in the technical sheet.
If these or other materials are used, they shall not be subjected to temperatures in excess of the thermal
capabilities as determined by aging tests made on the materials themselves.
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.

Compliance is checked by the tests of 15.2, followed immediately by the spillage test of 15.3,

and this is followed by the tests of 11.6 and the tests of Clause 16.

Following these tests an inspection is made within the enclosures. The water which may have

entered the enclosure shall not have reduced the creepage distances and clearances below
the minimum values specified in clause 29.
NOTE 101 Appliances designed to be installed completely inside a building and which have no outdoor parts, are
not subjected to the test of 15.2.
The motor-compressor is not operated during the tests of 15.2 and 15.3
15.2 Appliances other than IPXO are subjected to the tests of IEC 60529 as follows:
– IPX1 appliances as described in 14.2.1;
– IPX2 appliances as described in 14.2.2;
– IPX3 appliances as described in 14.2.3;
– IPX4 appliances as described in 14.2.4;
– IPX5 appliances as described in 14.2.5;
– IPX6 appliances as described in 14.2.6;
– IPX7 appliances as described in 14.2.7;
For this test the appliance is immersed in water containing 1 % NaCI by weight.
15.3 The appliance is installed according to the manufacturer's installation instructions, but
not operated. Covers which provide access for manual operation of electrical controls are set
in the open position, unless such covers are of the self-closing type. A solution of 0,25 liters
of water containing 2,5 gram of ordinary table salt is poured onto the unit in a manner most
likely to cause entrance of the water into or on electrical controls or uninsulated live parts.
After the spillage is completed, the appliance shall withstand the tests of clause 16. The
spillage test is not applicable to units if the minimum dimension of a horizontal or near
horizontal top surface of the cabinet is 75 mm or less.

16 Leakage current and electric strength
This clause of Part 1 is applicable except as follows.
16.2 Modification:
For stationary class 1 appliances, the leakage current shall not exceed 2 mA per kilowatt of
rated power input, with a maximum value of 10 mA for appliances accessible to the general
public and a maximum value of 30 mA for appliances not accessible to the general public.
17 Overload protection of transformers and associated circuits
This clause of Part 1 is applicable.

– 16 – 60335-2-104  IEC:2003(E)

18 Endurance
This clause of Part 1 is not applicable.

19 Abnormal operation
This clause of Part 1 is replaced by the following.

19.1 Appliances shall be so constructed that the risk of fire, or of mechanical damage

impairing safety or protection against electric shock, as a result of abnormal or careless

operation is obviated, as far as practicable. Failure of the transfer medium flow, or of any
control devices, shall not result in a hazard.
Electronic circuits shall be designed and applied so that a fault condition will not render the
appliance unsafe with regard to electric shock, fire hazard, mechanical hazard or dangerous
malfunction.
Appliances are subjected to the tests specified in 19.2 to 19.6.
Appliances incorporating electronic circuits are also subjected to the tests of 19.7 and 19.8
as applicable.
During and after the tests the appliance shall comply with the requirement of 19.9.
19.2 The motors, other than motor-compressors, are mounted on a support of wood or
similar material. The motor rotors are locked; fan blades and brackets are not removed.
The motors are supplied at the rated voltage of the appliance, or at the upper limit of the
rated voltage range, in a circuit as shown in Figure 101.
Under these conditions, the assembly is operated for 15 days (360 h) or until a protection
device permanently opens the circuit, whichever is the shorter period.
During the test, the ambient temperature is maintained at 23°C ± 5 °C.
If the temperature of the motor windings does not exceed 90 °C when steady conditions are
established, the test is considered to be ended.
During the test, the temperature of the enclosure shall not exceed 150 °C and the

temperature of the windings shall not exceed the values shown in Table 8.

60335-2-104  IEC:2003(E) – 17 –

Three days (72 h) after the beginning of the test, the motor shall withstand an electric strength

test as specified in 16.3.
During the test, a 30mA residual current device shall not open.

At the end of the test, the leakage current between the windings and the enclosure is

measured and shall not exceed 2mA, the motor being supplied at twice the rated voltage.

19.3 If the motor-compressor has not been type-tested against the requirements of

IEC 60335-2-34, a sample shall be provided with the rotor locked and being filled with oil and
refrigerant as intended.
The sample shall then be subjected to the locked rotor test specified in 19.101, 19.102 and
19.103 of IEC 60335-2-34 and shall comply with the requirements of this subclause.
19.4 Appliances incorporating three-phase motors are operated under the conditions of
Clause 11 at rated voltage or at the upper limit of the rated voltage range with one phase
disconnected, until steady conditions are obtained or the protective device operates. This
test is not applicable to three-phase motor compressors complying with IEC 60335-2-34
19.5 The appliance is operated under conditions in Clause 11 and at rated voltage, with any
form of operation, or any defect which may be expected during normal use. Only one fault
condition is reproduced at a time, the tests being made consecutively.
Examples of fault conditions include the following:
– the programme controller, if any, stopping in any position;
– disconnection and reconnection of one or more phases of the supply;
– open-circuiting or short-circuiting of components.
In general, tests are limited to those cases which may be expected to give the most
unfavourable results.
Locking in the “on” position of the main contacts of a contact intended for switching on and off
the heating element(s) in normal use is considered to be a fault condition, unless the
appliance is provided with at least two sets of contacts connected in series. This condition is,
for example, achieved by providing two contactors operating independently of each other or
by providing one contactor having two independent armatures operating two independent sets
of main contacts.
19.6 Compliance for electronic circuits is checked by evaluation of the fault conditions
specified in 19.6.2 for all circuits or parts of circuits, unless they comply with the conditions
specified in 19.6.1.
If the safety of the appliance under any of the fault conditions depends on the operating of a
miniature fuse-link complying with IEC 60127, the test of 19.7 is made.
During and after each test, the temperature of the windings shall not exceed values specified
in Table 6 and the appliance shall comply with the conditions specified in 19.10. In particular,
live parts shall not be accessible to the test finger or the test pin, as specified in Clause 8.
Any current flowing through protective impedance shall not exceed the limits specified in
8.1.4.
If a conductor of a printed circuit becomes open-circuited, the appliance is considered to have
withstood the particular test, provided all three of the following conditions are met:

– 18 – 60335-2-104  IEC:2003(E)

• the material of the printed circuit board withstands the burning test of 20.1 of IEC 60065;

• any loosened conductor does not reduce the creepage distances or clearances between

live parts and accessible metal parts below the values specified in Clause 29;

• the appliance withstands the tests of 19.7.2 with the open-circuited conductor bridged.

NOTE 101 Unless it is necessary to replace components after any of the tests, the electric strength test of 19.9

need only be carried out after the final test on the electronic circuit.

NOTE 102 In general, examination of the appliance and its circuit diagram will reveal the fault conditions which
have to be simulated, so that testing can be limited to those cases which may be expected to give the most
unfavourable results.
NOTE 103 In general, the tests take into account any failure which may arise from perturbations on the mains

supply. However, where more than one component may be affected simultaneously, it may be necessary to carry
out additional tests, which are under consideration.
19.6.1 Fault conditions a) to f) specified in 19.6.2 are not applied to circuits or parts of
circuits where both of the following conditions are met:
• the electronic circuit is a low-power circuit as described below;
the protection against electric shock, fire hazard, mechanical hazard or dangerous
malfunction in other parts of the appliance does not rely on the correct functioning of the
electronic circuit.
A low power circuit is determined as follows; an example is shown in figure 9.
The appliance is supplied at rated voltage and a variable resistor adjusted to its maximum
resistance is connected between the point to be investigated and the opposite pole of the
supply source.
The resistance is then decreased until the power consumed by the resistor reaches a
maximum. Points closest to the supply at which the maximum power delivered to this resistor
does not exceed 15 W at the end of 5 s are called low-power points. T

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.

INTRODUCTION
Il a été considéré en établissant la présente Norme internationale que l'exécution de ses
dispositions 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 prescriptions 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 prescriptions.
Un appareil utilisant des matériaux ou présentant des modes de construction différents de
ceux décrits dans les prescriptions de cette norme peut être examiné et essayé en fonction de
l'objectif poursuivi par ces prescriptions 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.
