AUTOMATIC ELECTRICAL CONTROLS –

Part 2-14: Particular requirements for electric actuators

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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 60730-2-14 has been prepared by IEC technical committee 72: Automatic electrical
controls. It is an International Standard.
This third edition cancels and replaces the second edition published in 2017,
Amendment 1:2019 and Amendment 2:2021. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
Adoption of IEC 60730-1:2022 with all its significant changes to IEC 60730-1:2013,
IEC 60730-1:2013/AMD1:2015 and IEC 60730-1:2013/AMD2:2020.

– 4 – IEC 60730-2-14:2025 © IEC 2025
The text of this International Standard is based on the following documents:
Draft Report on voting
72/1476/FDIS 72/1479/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/publications.
A list of all parts of the IEC 60730 series, under the general title: Automatic electrical controls,
can be found on the IEC website.
This part 2-14 is intended to be used in conjunction with IEC 60730-1:2022. Consideration may
be given to future editions of, or amendments to, IEC 60730-1.
This part 2-14 supplements or modifies the corresponding clauses in IEC 60730-1, so as to
convert that publication into the IEC standard: Particular requirements for electric actuators.
Where this part 2-14 states "addition", "modification" or "replacement", the relevant require-
ment, test specification or explanatory matter in part 1 should be adapted accordingly.
When a particular subclause of Part 1 is not mentioned in this Part 2-14, that subclause applies.
In the development of a fully international standard, it has been necessary to take into
consideration the differing requirements resulting from practical experience in various parts of
the world and to recognize the variation in national electrical systems and wiring rules.
The reader's attention is drawn to the fact that Annex R to Annex T list all of the "in-some-
country" clauses on differing practices of a less permanent nature relating to the subject of this
document.
In this publication:
1) The following print types are used:
– test specifications: in italic type;
2) Subclauses, notes or items which are additional to those in Part 1 are numbered starting
from 101, additional annexes are lettered AA, BB, etc.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn, or
• revised.
AUTOMATIC ELECTRICAL CONTROLS –

Part 2-14: Particular requirements for electric actuators

1 Scope
Replacement:
This part of IEC 60730 applies to automatic electric actuators
• for use in, on, or in association with equipment for household appliance and similar use;
NOTE 1 Throughout this document, the word "equipment" means "appliance and equipment" and "control" means
"electric actuator".
EXAMPLE 1 Electric actuators for appliances within the scope of IEC 60335.
• for building automation within the scope of ISO 16484 series and IEC 63044 series
(HBES/BACS);
EXAMPLE 2 Independently mounted electric actuators for HVAC air-handling systems.
• for equipment that is used by the public, such as equipment intended to be used in shops,
offices, hospitals, farms and commercial and industrial applications;
EXAMPLE 3 Electric actuators for commercial catering, heating, and air-conditioning equipment.
• that are smart enabled;
• that are AC or DC powered electric actuators with a rated voltage not exceeding 690 V AC
or 600 V DC;
• used in, on, or in association with equipment that use electricity, gas, oil, solid fuel, solar
thermal energy, etc., or a combination thereof;
• utilized as part of a control system or controls which are mechanically integral with
multifunctional controls having non-electrical outputs;
• using NTC or PTC thermistors and to discrete thermistors, requirements for which are
contained in Annex J;
• that are mechanically or electrically operated, responsive to or controlling such
characteristics as temperature, pressure, passage of time, humidity, light, electrostatic
effects, flow, or liquid level, current, voltage, acceleration, or combinations thereof;
• as well as manual controls when such are electrically and/or mechanically integral with
automatic controls.
NOTE 2 Requirements for manually actuated mechanical switches not forming part of an automatic control are
contained in IEC 61058-1-1.
This document applies to
– the inherent safety of automatic electric actuators, and
– functional safety of automatic electric actuators and safety related systems,
– controls where the performance (for example the effect of EMC phenomena) of the product
can impair the overall safety and performance of the controlled system,
– the operating values, operating times, and operating sequences where such are associated
with equipment safety.
This document specifies the requirements for construction, operation and testing of automatic
electric actuators used in, on, or in association with an equipment.

– 6 – IEC 60730-2-14:2025 © IEC 2025
This document does not
• apply to automatic electric actuators intended exclusively for industrial process
applications unless explicitly mentioned in the relevant part 2 or the equipment standard.
However, this document can be applied to evaluate automatic electric actuators intended
specifically for industrial applications in cases where no relevant safety standard exists;
• take into account the response value of an automatic action of an electric actuator, if
such a response value is dependent upon the method of mounting the electric actuator in
the equipment. Where a response value is of significant purpose for the protection of the
user, or surroundings, the value defined in the appropriate equipment standard or as
determined by the manufacturer will apply;
• address the integrity of the output signal to the network devices, such as interoperability
with other devices unless it has been evaluated as part of the control system;
• apply to electric actuators which are mechanically integrated with valves covered by a
separate part 2 (e.g. IEC 60730-2-8);
• apply to electric motors, requirements for which are contained in IEC 60034.

in the appropriate Tables 18, 19, 20.

Additional footnotes:
Electric actuators can be also classified as components of a multipurpose control or system.
Electric actuators are subjected to a minimum of 6 000 cycles.
This may be given as a maximum percentage of ON time of the power supply to avoid over-heating of the
windings in a declared period of time.
For integrated and incorporated electric actuators, the method is D.
An action in which the electric actuator assumes a predefined position upon loss of the electrical supply
and/or upon loss of the control signal is classified as type 1.AA or type 2.AA.
An action in which the electric actuator operates normally between 1,1 VR and 0,85 VR inclusive and in
which it either operates normally or assumes a predefined position between 0,85 VR and a declared lower
percentage of rated voltage is classified as type 1.AB or type 2.AB.
For test purposes, representative physical load may be defined by agreement between the manufacturer
and testing authority (e.g. dedicated test device).
Maximum rated mechanical load for rotary movement actuators can be declared in terms of rated torque
(for the complete angular rotation) or, alternatively, in terms of maximum torque, running torque and
percentage of the angular rotation in which the maximum torque occurs. The value of the percentage of
the angular rotation in which the maximum torque occurs is independent from any specific position within
the travel of the actuator; maximum torque can be reached at any position within the actuator travel (e.g.
at start position, at end position, at each end, in the middle, etc.).
Maximum rated mechanical load for linear movement actuators can be declared in terms of rated force
(for the complete stroke) or, alternatively, in terms of maximum force, running force and percentage of the
stroke in which the maximum force occurs. The value of the percentage of the stroke in which the
maximum force occurs is independent from any specific position within the travel of the actuator; maximum
force can be reached at any position within the actuator travel (e.g. at start position, at end position, at
each end, in the middle, etc.).

5.3 Class II symbol

If an electric actuator is a component of a multi-purpose control or system and provides a
protective control function, then the electric actuator shall be treated as a protective control
throughout Clause H.25.
26 Abnormal operation tests
This clause of Part 1 is applicable except as follows.
26.1 Abnormal temperature test
26.1.1 Burnout test
26.1.1.1 Modification:
Replace the first sentence with the following new text:
This subclause is applicable to electric actuators where an external mechanical blockage will
not cause an internal overload of the actuator. If means (e.g. a clutch) is used to decouple the
external blockage to the internal mechanical structure, then a blockage of the mechanical parts
between the motor and the decoupling means shall be tested according to 26.1.1.2 and
26.1.1.3.

26.1.1.3 Replacement:
After this test, the actuator shall comply with the items a) to g) of 13.1.3.8.
26.1.2 Blocked mechanical output test
26.1.2.1 Replacement:
Electric actuators where the motor employs insulation for the protection against electric shock
shall withstand the effects of blocked mechanical output without exceeding the temperatures
indicated in Table 29. Temperatures are measured by the method specified in 16.7 a).
Electric actuators where the motor employs only functional insulation shall withstand the
effects of a blocked mechanical output. During the test, the exceeding of temperatures in
Table 29 is allowed provided that, after the test, the electric actuator complies with items a)
to g) of 13.1.3.8, where applicable.
This test is not conducted on electric actuators which meet the requirements of 16.4.101.
26.1.2.2 Modification:
Replace the first and second paragraphs with the following new paragraph and note:
Electric actuators are tested for 24 h or until thermal equilibrium has been reached with the
output blocked in the most unfavourable position at rated voltage and in a room temperature in
the range of 15 °C to 30 °C, the resulting measured temperature being corrected to a 25 °C
reference value.
NOTE For the test with disconnected phase on three phase actuators, see 26.1.101.
Additional subclauses:
26.1.101 Test with disconnected phase on three phase actuators
With any one phase disconnected, the electric actuator is operated under normal operation and
supplied at rated voltage. For asymmetrical motor windings, the test is to be repeated until all
phases have been singly opened.
The test duration shall be such that the first and second hour winding temperatures are recorded
or until temperatures stabilize, whichever is longer. Temperatures are measured by the method
specified in 16.7 a).
The temperature of the winding shall not exceed the temperatures indicated in Table 29.
26.1.102 Running overload
26.1.102.1 A running overload test is carried out on electric actuators that are intended to be
remotely or automatically controlled or liable to be operated continuously in unattended mode.
If present, overload protective devices relying on electronic circuits to protect the motor
windings are also subjected to the running overload test. This test is not applicable to integrated
actuators.
26.1.102.2 The electric actuator is operated under normal operation, carrying its rated load
and supplied at rated voltage until the temperature of the motor windings stabilizes. The
protector or protective circuit shall not operate or open the circuit while the actuator is operating
under the above conditions.
26.1.102.2.1 For all electric actuators where the trip point in the sensing variable is not known
or cannot be quickly determined (for example, temperature sensing, impedance protected
motors, sensor-less motor protection, position sensing, etc.), the load to the actuator is
increased in increments of 10 % of the rated value (torque, current, etc.) and operated until
temperatures of the winding stabilize. If the protector or the protective circuit does not operate
under this overload condition, the load to the actuator is again increased by 10 % of the previous
load setting and the actuator is operated until temperatures of the windings stabilize. This
process is continued until the protective device or protective circuit operates. When the
protector or protective circuit operates, the load is slowly decreased until the protector or
protective circuit is not activated. The loading parameters (torque, current, etc.) shall be
measured and recorded. The actuator is then run at this load until the temperature of the winding
stabilizes. Any mechanical protection, such as a clutch, shall be defeated for this test.
26.1.102.2.2 For actuators where the trip point in the sensing variable is known or can be
quickly determined (for example, current sensing), the load to the actuator is gradually
increased, in a controlled manner, until the protective device or protective circuit is activated.
This is the trip point and the loading parameters (torque, current, etc.) shall be measured and
recorded. Then, the load is slowly decreased until the protector or protective circuit is not
activated. The actuator is then run at this load until the temperature of the winding stabilizes.
NOTE A brake dynamometer can be used to gradually increase the torque on the actuator shaft in a controlled
manner.
26.1.102.3 During the test, the winding temperature of motors employing insulation for the
protection against electric shock prior to the operation of the protective device or protective
circuit shall not exceed
– 140 °C, for class 105 (A) winding insulation;
– 155 °C, for class 120 (E) winding insulation;
– 165 °C, for class 130 (B) winding insulation;
– 180 °C, for class 155 (F) winding insulation;
– 200 °C, for class 180 (H) winding insulation;
– 220 °C, for class 200 (N) winding insulation;
– 240 °C, for class 220 (R) winding insulation;
– 270 °C, for class 250 winding insulation.
During the test, the maximum temperature recorded on insulating parts shall not exceed 1,5
times the relevant values specified in Clause 16.
Electric actuators where the motor employs only functional insulation shall comply with items
a) to g) of 13.1.3.8, where applicable.
NOTE If the load cannot be increased in appropriate steps, the motor and the protective electronics, if applicable,
can be removed from the appliance and tested separately.
26.1.102.4 For electric actuators which are used in a continuous operation for longer than
24 h without interruption, the load is again increased and the test is repeated until the protective
device operates or the motor stalls.
26.1.102.5 For electric actuators which are used in operation mode which will not exceed 24 h
without interruption, the test is repeated after the winding temperature has reached
environmental temperature conditions. The test will be performed with an increased load so that
the current through the motor windings is raised by 10 % increments. The electric actuator is
operated again until steady conditions are established, the supply voltage being maintained at
its original value. This procedure will be repeated until the protective device operates or the
motor stalls.
