IEC 60335-2-80:2015

Household and similar electrical appliances - Safety - Part 2-80: Particular requirements for fans

IEC 60335-2-80:2015 deals with the safety of electric fans for household and similar purposes, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. Examples of fans that are within the scope of this standard are ceiling fans; duct fans; partition fans; pedestal fans and table fans. This standard also applies to separate controls supplied with fans. 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. It also does not take into account children playing with the appliance. It was established on the basis of the fifth edition (2010) of that standard. This third edition cancels and replaces the second edition published in 2002, its Amendment 1 (2007) and its Amendment 2 (2011). It constitutes a technical revision. The principal changes in this edition as compared with the second edition of IEC 60335-2-80 are as follows (minor changes are not listed):
- added definition for ceiling fan suspension system (3.102);
- added instructions for ceiling fan maintenance (7.12);
- added instructions for ceiling fan installation (7.12.1);
- added entrapment assessment criteria for table and pedestal fan with a fan head that oscillates in the up-down direction (20.102);
- added requirements for insulation of pre-installed internal wiring used to supply attached luminaires (22.101);
- added suspension system failure protection requirements for ceiling fans (22.102);
- added motor brush wear requirements (27.3).
The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this standard be adopted for implementation nationally not earlier than 12 months or later than 36 months from the date of its publication. Key words: Fans, Duct fans, Pedestal fans, Ceiling fans, Partition fans, Table fans

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
This part of International Standard IEC 60335 has been prepared by IEC technical committee
61: Safety of household and similar electrical appliances.
This third edition cancels and replaces the second edition published in 2002 including its

INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its
provisions is entrusted to appropriately qualified and experienced persons.
This standard recognizes the internationally accepted level of protection against hazards such
as electrical, mechanical, thermal, fire and radiation of appliances when operated as in
normal use taking into account the manufacturer's instructions. It also covers abnormal
situations that can be expected in practice and takes into account the way in which
electromagnetic phenomena can affect the safe operation of appliances.
This standard takes into account the requirements of IEC 60364 as far as possible so that
there is compatibility with the wiring rules when the appliance is connected to the supply
mains. However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with
in Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of
the requirements and, if found to be substantially equivalent, may be considered to comply
with the standard.

Part 2-80: Particular requirements for fans

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition. A vertical bar appears in the margin wherever a change
has been made. Additions are in green text, deletions are in strikethrough red text.

This part of International Standard IEC 60335 has been prepared by IEC technical committee

INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its
provisions is entrusted to appropriately qualified and experienced persons.
This standard recognizes the internationally accepted level of protection against hazards such
as electrical, mechanical, thermal, fire and radiation of appliances when operated as in
normal use taking into account the manufacturer's instructions. It also covers abnormal
situations that can be expected in practice and takes into account the way in which
electromagnetic phenomena can affect the safe operation of appliances.
This standard takes into account the requirements of IEC 60364 as far as possible so that
there is compatibility with the wiring rules when the appliance is connected to the supply
mains. However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with
in Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of
the requirements and, if found to be substantially equivalent, may be considered to comply
with the standard.

Part 2-80: Particular requirements for fans

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
This part of International Standard IEC 60335 has been prepared by IEC technical committee
61: Safety of household and similar electrical appliances.
This bilingual version (2018-11) corresponds to the monolingual English version, published in
2015-04.
This third edition cancels and replaces the second edition published in 2002 including its

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.

with a diameter of 50 mm instead of the non-circular face. The test probe is applied with a
force not exceeding 5 N.
21.102 Ceiling fans shall have adequate strength.
Compliance is checked by the following test.
Ceiling fans are mounted in accordance with the installation instructions. A load equal to four
times the mass of the fan is suspended from the body of the fan for 1 min.
A torque of 1 Nm is then applied to the fixed body of the fan for 1 min. The test is repeated
with the torque applied in the reverse direction.
The suspension system including any safety suspension system device shall not break
and the fan shall not be damaged to such an extent that compliance with 8.1, 16.3 and
Clause 29 is impaired.
NOTE The intent is to test the parts of the ceiling fan and not the capability of the ceiling materials.
22 Construction
This clause of Part 1 is applicable except as follows.
22.1 Addition:
NOTE 101 The enclosure defined in IEC 60529 does not include guards for fan blades.
22.11 Modification:
The 50 N force is not applied to clips used to fasten fan guards. Instead, a force of 15 N is
applied in any direction to the clips in an attempt to release them.
22.101 Appliances having provision for attaching a luminaire shall incorporate appropriate
terminals and internal wiring. The internal wiring associated with the luminaire shall have
insulation at least equivalent to silicone rubber compound type IE2 complying with
IEC 60245-3. This requirement is not applicable to fans incorporating a luminaire that cannot
be replaced without breaking the appliance.
Compliance is checked by inspection.

22.102 The ceiling fan shall be constructed so that a failure of the fixing device of the motor
to the mounting rod could not give rise to risk of injury to the user or surroundings.
Compliance is checked by the requirement and inspection or test of 22.102.1, 22.102.2,
22.102.3, 22.102.4 or 22.102.5, as appropriate for the design. After the test, the ceiling fan
shall not be damaged to such an extent that compliance with Clause 8.1, 16.3, 29.1 and 29.2
are impaired.
22.102.1 The ceiling fan shall incorporate a device that disconnects the fan from the supply
before the suspension system fails. An example of this construction is shown in Figure 101.
Compliance is checked by the following test.
The bolt that connects the down rod to the motor is replaced with the specially prepared test
pin shown in Figure 102 that simulates wear on the bolt. The pin is fully inserted so that it
connects the down rod to the motor.
The fan is supplied at rated voltage and operated at maximum speed. The pin is then
partially withdrawn so that the motor is connected to the down rod by that part of the pin
having diameter b.
The supply to the ceiling fan shall be automatically disconnected and the fan shall not be
capable of operation without replacing the worn bolt.
22.102.2 The ceiling fan shall be constructed so that the fan motor and blades do not fall
more than 300 mm after failure of the suspension system and the fan shall be disconnected
from the supply. An example of this construction is shown in Figure 103.
Compliance is checked by the following test.
The ceiling fan is installed in accordance with the manufacturer’s instructions.
A load equal to two times the mass of the ceiling fan is suspended from its body.
The fan is supplied at rated voltage and operated at maximum speed.
The suspension system is then simulated to fail by disconnecting the motor from the down
rod.
The motor and fan blades shall not drop more than 300 mm from their original position and
the supply to the ceiling fan shall be automatically disconnected.
22.102.3 The ceiling fan shall be constructed so that the fan blades and motor are
connected to the suspension system via a threaded down rod that is locked by means of one
or more setscrews. An example of this construction is shown in Figure 104.
Compliance is checked by inspection.
22.102.4 The ceiling fan shall be constructed so that an additional through bolt, lock washer
and nut, or the like limits the distance of drop by no more than 75 mm in case of the
suspension system failure. An example of this construction is shown in Figure 105.
Compliance is checked by inspection and measurement

22.102.5 The ceiling fan shall be constructed so that all components required to prevent the
failure of the suspension system are treated or coated to resist corrosion. Any fixing bolts
shall have a minimum diameter of 5 mm and a minimum tensile strength of 200 MPa. Any
such bolts shall have provision to prevent them working loose due to vibration. An example of
this construction is shown in Figure 106.
Compliance is checked by inspection and measurement.
23 Internal wiring
This clause of Part 1 is applicable except as follows.
23.3 Modification:
Instead of moving the movable part backwards and forwards, fans with an oscillating
mechanism are tested as follows.
Fans are supplied at rated voltage and operated under normal operation, the angle of
oscillation being the maximum allowed by the construction. The test is carried out for 100 000
cycles of oscillation.
24 Components
This clause of Part 1 is applicable except as follows.
24.2 Addition:
Appliances having a rated power input not exceeding 25 W may be fitted with a switch in the
supply cord.
24.101 Thermal cut-outs incorporated in duct fans in order to comply with Clause 19 shall
not be self-resetting.
Compliance is checked by inspection.
25 Supply connection and external flexible cords
This clause of Part 1 is applicable except as follows.
25.5 Addition:
Type Z attachment is allowed for portable fans.
26 Terminals for external conductors
This clause of Part 1 is applicable.
27 Provision for earthing
This clause of Part 1 is applicable except as follows.

27.3 Addition:
The allowed travel of the live and neutral brushes due to wear shall be less than the allowed
travel of the earth brush so that the earthing circuit is maintained even after the appliance
ceases to operate due to live and neutral brush wear.
Compliance is checked by inspection.
28 Screws and connections
This clause of Part 1 is applicable.
29 Clearances, creepage distances and solid insulation
This clause of Part 1 is applicable except as follows.
29.2 Addition:
The microenvironment is pollution degree 3 unless the insulation is enclosed or located so
that it is unlikely to be exposed to pollution during normal use of the appliance.
30 Resistance to heat and fire
This clause of Part 1 is applicable except as follows.
30.2.2 Not applicable.
31 Resistance to rusting
This clause of Part 1 is applicable.
32 Radiation, toxicity and similar hazards
This clause of Part 1 is applicable.
