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.
International Standard IEC 60335-2-95 has been prepared by IEC technical committee 61:
Safety of household and similar electrical appliances.
This fourth edition cancels and replaces the third edition published in 2011, Amendment 1:
2015 and Amendment 2:2017. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) the text has been aligned with edition 5.2 of Part 1;
b) reference to IEC 60335-2-97 and IEC 60335-2-103 has been revised to correctly state
their titles (Clause 1);
– 4 – IEC 60335-2-95:2019 © IEC 2019
c) specific instruction statements have been revised to separate them from information to be
provided (7.12);
d) the compliance criteria for the tests of 19.11.2 and 19.11.3 has been modified (19.13);
e) the tests for class III appliances and parts of class III constructions have been modified
(25.8, 25.15).
The text of this International Standard is based on the following documents:
FDIS Report on voting
61/5937/FDIS 61/5946/RVD
Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts of the IEC 60335 series, under the general title: Household and similar
electrical appliances – Safety, can be found on the IEC website.
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 fifth edition (2010) 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 drives for vertically
moving garage doors for residential use.
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 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 this publication be adopted for implementation
nationally not earlier than 12 months or later than 36 months from the date of publication.
The following differences exist in the countries indicated below.
– 6.1: Class 0I appliances are allowed (Japan).
– 7.1: Additional markings are required (USA).
– 7.12.1: Additional warnings and instructions are required (USA).
– 11.7: The test conditions are different (USA).
– 19.9: A running overload test is carried out (USA).
– 20.101: The test is not carried out (USA).

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.
HOUSEHOLD AND SIMILAR ELECTRICAL APPLIANCES –
SAFETY –
Part 2-95: Particular requirements for drives for vertically
moving garage doors for residential use

1 Scope
This clause of Part 1 is replaced by the following.
This part of IEC 60335 deals with the safety of electric drives for garage doors for residential
use that open and close in a vertical direction, the rated voltage of the drives 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 these electrically driven garage doors.
NOTE 101 Examples of garage doors are shown in Figure 101.
NOTE 102 The drive can be supplied with a garage door.
NOTE 103 This standard also applies to entrapment protection devices for use with drives. It does not cover
hazards related to the mechanisms of the door itself.
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 playing with the appliance by young children, but recognizes that
children may be in the vicinity of the garage door.
NOTE 104 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 105 This standard does not apply to drives
– for shutters, awnings, blinds and similar equipment (IEC 60335-2-97);
– for gates, doors and windows (IEC 60335-2-103);
– for commercial and industrial purposes;
– intended to be used in locations where special conditions prevail, such as the presence of a corrosive or
explosive atmosphere (dust, vapour or gas).

The drive is supplied at rated voltage but is not operated. It is loaded with 1,2 times the
rated load applied for 30 min. If the drive is supplied with a door, the load is applied to the
door and is equal to the highest force exerted by it. The highest force is determined with the
door in the most unfavourable position, the drive not being energized. Automatic operation of
automatic drives is rendered inoperative.
There shall be no movement except for removal of any play in the system.
The test is repeated with the drive supplied at 0,85 times rated voltage and with the supply
disconnected.
20.102 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 door and supplied at the most unfavourable voltage between
0,94 times and 1,06 times the rated voltage. It is operated to close the door. When the
actuating member of the switch is released,
– if the closing force exerted by the door does not exceeds 150 N, as measured in 20.104.1,
the bottom edge of the door shall stop;
– if the closing force exerted by the door exceeds 150 N, as measured in 20.104.1, the
bottom edge of the door shall stop before it has travelled more than 50 mm vertically.
The test is repeated during the opening movement of the door.
20.103 Drives incorporating an entrapment protection system with sensing devices which
prevent the door coming into contact with an obstacle shall not cause injury resulting from a
moving door.
Compliance is checked by the following test.
The drive is installed with a door, the force exerted by the drive is set at the maximum value
according to the instructions and the drive is supplied at the most unfavourable voltage
between 0,94 times and 1,06 times the rated voltage.
An obstacle having dimensions of approximately 80 mm × 300 mm and a height of 100 mm is
placed on the ground and centrally along its 300 mm length across the door opening. The
drive is operated to close the door from heights of 100 mm, 1 000 mm and the fully open
position of the door. The door shall not move or only move in the opening direction.
NOTE The obstacle is normally made of rough wood and painted white but other materials and colors can be used
to simulate the most unfavourable conditions.
The obstacle is positioned centrally in the door opening and is then raised in increments up to
300 mm from the height of the door, but not higher than 2,5 m. At each increment, the drive is
operated to close the door. The door shall stop within 50 mm or reverse its movement without
contacting the obstacle.
A cylindrical obstacle, having a diameter of 50 mm and a length of 850 mm, is suspended
centrally in the door opening. It is suspended vertically with the upper end at a height of
900 mm above the ground.
The drive is operated to close the door and the cylinder is swung across the door opening
from an angle of 45°. The entrapment protection system shall cause the door to reverse its
movement.
The test is repeated from the fully open position with the obstacle positioned at 100 mm from
each end of the door opening in turn.
During the tests, any biased-off switch is held closed.
20.104 Drives incorporating an entrapment protection system with sensing devices which
rely on the door contacting an obstacle shall not cause injury resulting from a moving door.
Compliance is checked by the test of 20.104.1. If the drive is an automatic drive, or a drive
that operates the driven part in at least one direction by a command that can be initiated via
a telecommunication or communication network, and for drives with a closing force exceeding
400 N, compliance is also checked by the test of 20.104.2 for a closing movement.
The drive is installed with a door, the force exerted by the drive is set at the maximum value
according to the instructions and the drive is supplied at the most unfavorable voltage
between 0,94 times and 1,06 times the rated voltage.
During the tests, any biased-off switch is held closed.
20.104.1 Any non-contact entrapment protection system is rendered inoperative.
The drive is operated to close the door from the fully open position and the entrapment
protection system shall limit the vertical component of the average closing force to
– 150 N during the first 5 s after the force has exceeded 25 N and
– 25 N thereafter;
or
– 400 N during the first 0,75 s after the force has exceeded 150 N,
– 150 N during a further period of 4,25 s and
– 25 N thereafter;
or
– 800 N during the first 2 s after the force has exceeded 150 N for doors that do not swing
outward,
– 600 N during the first 2 s after the force has exceeded 150 N for doors that swing outward,
– 150 N during a further period of 3 s and
– 25 N thereafter.
The force is measured by means of an instrument that incorporates a rigid plate having a
diameter of 80 mm and a spring having a ratio of 500 N/mm ± 50 N/mm. The spring acts on a
sensing element that is connected to an amplifier having a rise and fall time not exceeding
5 ms. The measuring instrument shall be accurate to within 5 %.
The force is measured on the bottom edge of the door at the following heights above the
ground:
– 50 mm;
– 300 mm;
– 500 mm;
– 2 500 mm, or 300 mm below the maximum opening height of the door if this is less than
2 800 mm.
At each height, the force is measured at the following locations:

– 16 – IEC 60335-2-95:2019 © IEC 2019
– in the centre of the bottom edge of the door;
– 200 mm from each end of the bottom edge of the door.
The test is carried out three times and the arithmetic average closing force is calculated for
each location.
NOTE The door can reverse its movement after contacting the obstacle.
20.104.2 An obstacle having dimensions of approximately 80 mm × 300 mm and a height of
100 mm is placed on the ground and centrally along its 300 mm length across the door
opening. The drive is operated to close the door from heights of 100 mm, 1 000 mm and the
fully open position of the door. The door shall not move or only move in the opening direction.
The test is repeated from the fully open position with the obstacle positioned at 100 mm from
each end of the door opening in turn.
A cylindrical obstacle, having a diameter of 50 mm and a length of 850 mm, is suspended
centrally in the door opening. It is suspended vertically with the upper end at a height of
900 mm above the ground.
The drive is operated to close the door and the cylinder is swung across the door opening
from an angle of 45°. The entrapment protection system shall cause the door to reverse its
movement.
20.105 Drives shall prevent entrapment in the opening direction.
Compliance is checked by the following test.
The force exerted by the drive is set at the maximum value according to the instructions. A
test piece having dimensions of approximately 200 mm × 300 mm, a height of 700 mm and a
mass of 20 kg ± 0,5 kg is fixed centrally to the outside of the door, with the 300 mm edge
adjacent to the bottom edge of the door.
The drive is supplied at the most unfavorable voltage between 0,94 times and 1,06 times the
rated voltage and operated to open the door. The movement of the door shall stop before the
test piece comes into contact with the lintel.
20.106 Entrapment protection systems shall provide an adequate level of protection in the
event of a failure within the system installation wiring.
Compliance is checked by the following test, unless the entrapment protection system is a
biased-off switch.
The drive is installed with a door and supplied at rated voltage. The drive is operated to
close the door. During the movement, a short circuit or open circuit is simulated in the system
installation wiring.
Unless the entrapment protection system continues to operate normally, the door shall stop
