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.

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.
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.

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 part of IEC 60335 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 units, their maximum rated voltages being not more than
250 V for single phase appliances and 600 V for all other appliances. Partial units are within
the scope of this International Standard.
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 3.121.
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 IEC 60335-2-34, which includes the statement that the
term motor-compressor is 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 refrigerants other than group those
classified as A1, A2L, A2 or A3 as defined by under ISO 817 or ANSI/ASHRAE 34 [ISO 817]
classification.
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.

–  10  –  IEC 60335-2-40:2013+AMD1:2016 CSV
 IEC 2016
NOTE 103 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.
NOTE 104 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).
