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.
The International Electrotechnical Commission (IEC) draws attention to the fact that it is claimed that compliance
with this document may involve the use of a patent concerning entrapment protection systems defined in 3.107 and the
particular function to override an entrapment protection system under fault conditions as described in 19.11.2 and
22.107.
IEC takes no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has assured the IEC that he is willing to negotiate licences under reasonable and
non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the
holder of this patent right is registered with IEC. Information may be obtained from:
The Chamberlain Group Inc.
845 Larch Avenue
Elmhurst, IL 60126
USA
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights
other than those identified above. IEC shall not be held responsible for identifying any or all such patent rights.

– 4 – 60335-2-103  IEC:2006+A1:2010
This consolidated version of IEC 60335-2-103 consists of the second edition (2006)
[documents 61/3002/FDIS and 61/3076/RVD] and its amendment 1 (2010) [documents
61/4048/FDIS and 61/4078/RVD]. It bears the edition number 2.1.
The technical content is therefore identical to the base edition and its amendment and
has been prepared for user convenience. A vertical line in the margin shows where the
base publication has been modified by amendment 1. Additions and deletions are
displayed in red, with deletions being struck through.
This part of International Standard IEC 60335 has been prepared by IEC technical committee 61:
Safety of household and similar electrical appliances.
The principal changes in this edition as compared with the first edition of IEC 60335-2-103 are
as follows. Minor changes are not listed.
– Adds definitions for automatic drive, horizontally moving pedestrian door and reversible
drive (3.109, 3.110, 3.111).
– Clarifies the marking requirements for reversible drives and horizontal moving pedestrian
doors (7.12 and 7.12.1).
– Clarifies requirements for the use of a biased-off switch (19.11.2, 20.109, 22.107).
– Clarifies the mechanical hazard requirements for drives (20.105, 20.107 to 20.107.2.3).
– Adds requirements for the use of pressure sensitive pads (20.107.1.4, Figure 102).
– Modifies the requirements for batteries supplied with automatic opening doors (22.204.2 in
Annex AA).
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its
amendments. It was established on the basis of the fourth edition (2001) of that standard.
NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60335-1.
This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as to
convert that publication into the IEC standard: Safety requirements for electric drives for
gates, doors and windows.
When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies
as far as is reasonable. When this standard states “addition”, “modification” or “replacement”,
the relevant text in Part 1 is to be adapted accordingly.
NOTE 2 The following numbering system is used:

– subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1;
– unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including
those in a replaced clause or subclause;
– additional annexes are lettered AA, BB, etc.

NOTE 3 The following print types are used:
– requirements: in roman type;
test specifications: in italic type;
–
– notes: in small roman type.
Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the
associated noun are also in bold.
The following differences exist in the countries indicated below.
– 6.1: Class 0 and class 01 are allowed for appliances for indoor use having a rated voltage up to 150 V (Japan).

60335-2-103  IEC:2006+A1:2010 – 5 –
The committee has decided that the contents of the base publication and its amendments will
remain unchanged until the stability date indicated on the IEC web site under
"http://webstore.iec.ch" in the data related to the specific publication. At this date, the
publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
NOTE 4 The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations may need a transitional period following publication of a new, amended or revised IEC publication in
which to make products in accordance with the new requirements and to equip themselves for conducting new or
revised tests.
It is the recommendation of the committee that the content of the amendment 1 be adopted for implementation
nationally not earlier than 12 months or later than 36 months from the date of publication.

IMPORTANT – The “colour inside” logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct understanding
of its contents. Users should therefore print this publication using a colour printer.

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.
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.
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 2-103: Particular requirements for drives
for gates, doors and windows
1 Scope
This clause of Part 1 is replaced by the following.
This International Standard deals with the safety of electric drives for horizontally and
vertically moving gates, doors and windows for household and similar purposes, their rated
voltage being not more than 250 V for single-phase appliances and 480 V for other
appliances. It also covers the hazards associated with the movement of the driven part.
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, offices,
hotels, restaurants, hospitals, in industry and on farms, are within the scope of this standard.
Requirements for drives for doors that may be used in emergency routes and exits are given
in Annex AA.
NOTE 101 Examples of drives within the scope of this standard are drives for
– folding doors;
– revolving doors;
– rolling doors;
– roof windows;
– sectional overhead doors;
– swinging and sliding gates or doors.
Examples are shown in Figure 101.
NOTE 102 Drives may be supplied with a driven part.
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
– the use of appliances by young children or infirm persons without supervision;
– playing with the appliance by young children.
– persons (including children) whose
• physical, sensory or mental capabilities; or
• lack of experience and knowledge
prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance.
NOTE 103 Attention is drawn to the fact that in many countries additional requirements are specified by the
national authorities responsible for the protection of labour and similar authorities.
NOTE 104 This standard does not apply to drives
– for vertically moving garage doors for residential use (60335-2-95);
– for rolling shutters covering doors and windows (including locations where the door is set back from the
shutter), awnings, blinds and similar equipment (60335-2-97);

– 8 – 60335-2-103  IEC:2006+A1:2010
– for horizontally moving pedestrian doors having an opening width exceeding 3 m and an opening area
exceeding 6,25 m ;
– intended exclusively to be used by trained persons in commercial and industrial premises;
– for specific purposes, such as fire barriers;
– intended to be used in locations where special conditions prevail, such as the presence of a corrosive or
explosive atmosphere (dust, vapour or gas).
NOTE 105 This standard does not apply to movement of a pedestrian door where such movement is based solely
on stored energy.

19 Abnormal operation
This clause of Part 1 is applicable except as follows.
19.1 Addition:
Compliance is also checked by the test of 19.101.
19.10 Addition:
For a drive having a manual release, the test is made with the driven part disconnected.
19.11.2 Addition:
If the drive can be operated when any of the fault conditions are simulated, the tests of
20.104 and 20.107 are carried out, the drive, however, being supplied at rated voltage.
Either the drive continues to fulfill the requirements, or, after a maximum of one cycle of
operation, it must stop with the driven part in a safe position, or the drive must change to a
biased-off switch mode of operation. When the drive is controlled by a single button control,
the biased-off switch shall not override the fault on its first activation unless the driven part
is at either end position of travel.
19.13 Addition:
During the test of 19.101, the winding temperature shall not exceed the values specified in
19.9.
19.101 Drives, other than those for continuous operation, are supplied at rated voltage and
operated continuously under normal operation.
20 Stability and mechanical hazards
This clause of Part 1 is applicable except as follows.
20.2 Addition:
NOTE 101 Moving parts of drives intended to be installed at a height of at least 2,5 m above the ground or other
access level are considered to be positioned so that adequate protection is provided.
Moving parts of drives intended to be installed at a height of at least 2,5 m above the ground
or other access level are considered to be positioned so to provide adequate protection
against personal injury in normal use.
NOTE 102 101 Stairs and terraces are examples of access levels. Surfaces not normally used for standing on,
such as window-sills, and movable equipment such as ladders, are not considered to be access levels.
NOTE 103 102 For horizontally moving pedestrian doors, moving parts including interconnecting parts of their
drives need not be guarded if the gap between fixed and moving parts is below 8 mm, or above 25 mm, or it is at
least 2 m above the ground. This also applies to the gap between parts that may move at different speeds.

20.101 Drives shall prevent vertically moving driven parts from closing unexpectedly.
Compliance is checked by the following test.
The drive is supplied at the most unfavourable voltage between 0,94 and 1,06 times rated
voltage but is not operated. Automatic operation of automatic drives is disabled. It is loaded
with 1,2 times the rated load applied for 30 min. If the drive is supplied with a driven part,
the load is applied to the driven part and is equal to the highest force exerted by it.
There shall be no movement except for initial removal of any play in the system.
NOTE 1 The highest force is determined with the driven part in the most unfavourable position, the drive not
being energized.
NOTE 2 It is to be noted that compliance with this clause does not necessarily cover risks due to operation of the
driven part. For vertically moving doors, anti-drop or equivalent safety devices might be necessary.
The test is repeated with the supply disconnected.
20.102 A manual release or reversible drive shall be easy to operate. Operation of the
release shall not give rise to a hazard such as kickback or unexpected operation of the drive.
The drive shall not create any hazard when the manual release is activated.
Operation of a reversible drive used as a means for a manual release shall not give rise to a
hazard.
Compliance is checked by the following test.
Automatic operation of automatic drives is disabled.
The drive is installed with a driven part and supplied at the most unfavourable voltage
between 0,94 and 1,06 times rated voltage. The drive is adjusted for the highest opening
and closing forces, if such adjustment is mentioned in the instructions. The manual release is
operated when the driven part has stopped at each terminal position, in turn. The release or
reversible drive shall be operable with a force not exceeding 220 N or a torque not
exceeding 1,6 Nm. The force is applied as stated in the instructions.
The test is repeated with the power supply interrupted.
When the manual release has been activated, the power supply is then restored and the drive
activated. The drive shall not move, or if the drive moves, all requirements of this standard
shall be met.
20.103 A mechanical fault in the drive shall not result in a hazardous operation.
Compliance is checked by inspection and, if necessary, by test.
The inspection shall evaluate which parts can affect the safety of operation and whether they
are likely to break or become loose. These parts may be part of the drive or used for
connecting the drive to the driven part.
NOTE Examples of parts that are evaluated are screws, pins, shafts, wheels, chains and supporting parts.
If inspection cannot determine whether the drive will continue to operate normally or stop its
movement when the part has failed, the following test is carried out.

– 16 – 60335-2-103  IEC:2006+A1:2010
The drive is installed with a driven part, the force exerted by the drive being adjusted to its
highest value in accordance with the instructions. The drive is supplied at the most
unfavourable voltage between 0,94 and 1,06 times rated voltage.
The faults are introduced one at a time and the drive is operated as in normal use.
Unless the drive and the driven part continue to operate normally, all of the following
conditions shall be fulfilled:
−  the drive shall stop operating at least by the end of the cycle of movement;
−  further operation shall not be possible;
−  the speed of the driven part shall not increase by more than 20 %.
20.104 Drives controlled by a biased-off switch shall stop when the actuating member of
the switch is released.
Compliance is checked by the following test.
The drive is installed with a driven part and supplied at the most unfavourable voltage
between 0,94 and 1,06 times rated voltage. It is operated to close the driven part.
When the actuating member of the switch is released, the leading edge of the driven part
shall stop within a distance of 20 mm for windows, and for other driven parts within a
distance of
– 50 mm when the opening gap does not exceed 500 mm;
– 100 mm when the opening gap exceeds 500 mm.
The test is repeated during the opening movement of the driven part.
The requirement for the driven part to stop within the specified distance only applies if the
closing force exerted by the driven part exceeds 150 N, as measured in 20.107.2.1.
20.105 During the movement of the drive in either direction, the actuation of a manual
control shall stop the movement if there is no separate button for the stop function.
If the drive has a single button for controlling the movement, further actuation shall reverse
the direction of movement.
If the drive has three buttons for controlling the movement, one button shall be a stop button.
These requirements do not apply to controls affecting automatic modes of operation.
Any button that has a stop function shall not require a key to stop the drive.
Compliance is checked by a manual test.
NOTE The test may be carried out without a driven part.
20.106 Drives shall not restart automatically after the movement has stopped uninten-
tionally.
NOTE 1 Unintentional stopping may be caused by interruption of the power supply or by operation of a thermal
cut-out.
Compliance is checked by the following tests.
