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) 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 60730-2-14 has been prepared by IEC technical committee 72:
Automatic electrical controls.
This second edition cancels and replaces the first edition, published in 1995, its Amendment 1
(2001) and its Amendment 2 (2007). This edition constitutes a technical revision. This edition
includes the following significant technical changes with respect to the previous edition:
th
• adapting it to the 5 Ed of IEC 60730-1,
• addition of checking electric actuators with action 1.AB or 2AB, and
• modification of tests under abnormal condition.
This Part 2-14 is intended to be used in conjunction with IEC 60730-1. It was established on
th
the basis of the 5 edition of that standard (2013). Consideration may be given to future
editions of, or amendments to, IEC 60730-1.

– 4 – IEC 60730-2-14:2017 © IEC 2017
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.
Where no change is necessary part 2-14 indicates that the relevant clause or 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 "in some countries" notes regarding differing national practice are contained in the
following subclauses:
• Table 1,
• 27.2.3.1.
In this publication:
1) The following print types are used:
– requirements proper: in roman type;
– test specifications: in italic type;
– explanatory matter: in smaller roman type.
– Defined terms: bold 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 text of this International Standard is based on the following documents:
FDIS Report on voting
72/1079/FDIS 72/1100/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 document has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,

reference value.
NOTE For the test with disconnected phase on three phase actuators, see 27.101.
27.3 Not applicable.
27.101 Test with disconnected phase on three phase actuators
27.101.1 With any one phase disconnected, the 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.
27.101.1.1 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 14.7.1.
27.101.1.2 The temperature of the winding shall not exceed the temperatures indicated in
Table 26.
27.102 Running overload
27.102.1 A running overload test is carried out on electrical 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.
27.102.2 The electrical 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.
27.102.2.1 For all 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.
27.102.2.2 For actuators where the trip point in the sensing variable is known or can be
quickly determined (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

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) 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 consolidated version of the official IEC Standard and its amendment has been
prepared for user convenience.
IEC 60730-2-14 edition 2.1 contains the second edition (2017-08) [documents 72/1079/
FDIS and 72/1100/RVD] and its amendment 1 (2019-03) [documents 72/1168FDIS and
72/1175/RVD].
In this Redline version, a vertical line in the margin shows where the technical content
is modified by amendment 1. Additions are in green text, deletions are in strikethrough
red text. A separate Final version with all changes accepted is available in this
publication.

International Standard IEC 60730-2-14 has been prepared by IEC technical committee 72:
Automatic electrical controls.
This second edition constitutes a technical revision. This edition includes the following
significant technical changes with respect to the previous edition:
th
• adapting it to the 5 Ed of IEC 60730-1,
• addition of checking electric actuators with action 1.AB or 2AB, and
• modification of tests under abnormal condition.
This part 2-14 is intended to be used in conjunction with IEC 60730-1. It was established on
the basis of the fifth edition of that standard (2013) including its amendment 1 (2015).
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.
Where no change is necessary part 2-14 indicates that the relevant clause or 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 "in some countries" notes regarding differing national practice are contained in the
following subclauses:
• Table 1,
• 27.2.3.1.
In this publication:
1) The following print types are used:
– requirements proper: in roman type;
– test specifications: in italic type;
– explanatory matter: in smaller roman type.
– Defined terms: bold 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.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

© IEC 2019
The committee has decided that the contents of the base publication and its amendment 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.
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 document using a
colour printer.

reference value.
NOTE For the test with disconnected phase on three phase actuators, see 27.101.
27.3 Not applicable.
© IEC 2019
27.101 Test with disconnected phase on three phase actuators
27.101.1 With any one phase disconnected, the 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.
27.101.1.1 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 14.7.1.
27.101.1.2 The temperature of the winding shall not exceed the temperatures indicated in
Table 26.
27.102 Running overload
27.102.1 A running overload test is carried out on electrical 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.
27.102.2 The electrical 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.
27.102.2.1 For all 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.
27.102.2.2 For actuators where the trip point in the sensing variable is known or can be
quickly determined (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.
27.102.3 During the test, the winding temperature 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;

– 16 – IEC 60730-2-14:2017+AMD1:2019 CSV
© IEC 2019
– 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.
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.
27.102.3.1 During the test, the maximum temperature recorded on insulating parts shall not
exceed 1,5 times the relevant values specified in Clause 14.
27.102.4 For electrical 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.
27.102.5 For electrical 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 electrical
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

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) 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 consolidated version of the official IEC Standard and its amendments has been
prepared for user convenience.
IEC 60730-2-14 edition 2.2 contains the second edition (2017-08) [documents
72/1079/FDIS and 72/1100/RVD], its amendment 1 (2019-03) [documents 72/1168FDIS
and 72/1175/RVD] and its amendment 2 (2021-10) [documents 72/1284/FDIS and
72/1286/RVD].

International Standard IEC 60730-2-14 has been prepared by IEC technical committee 72:
Automatic electrical controls.
This second edition constitutes a technical revision. This edition includes the following
significant technical changes with respect to the previous edition:
th
• adapting it to the 5 Ed of IEC 60730-1,
• addition of checking electric actuators with action 1.AB or 2AB, and
• modification of tests under abnormal condition.

operation and supplied at rated voltage. For asymmetrical motor windings, the test is to be
repeated until all phases have been singly opened.
27.101.1.1 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 14.7.1.
27.101.1.2 The temperature of the winding shall not exceed the temperatures indicated in
Table 26.
27.102 Running overload
27.102.1 A running overload test is carried out on electrical actuators that are intended to be
remotely or automatically controlled or liable to be operated continuously in unattended mode.

– 16 – IEC 60730-2-14:2017+AMD1:2019
+AMD2:2021 CSV © IEC 2021
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.
27.102.2 The electrical 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.
27.102.2.1 For all 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.
27.102.2.2 For actuators where the trip point in the sensing variable is known or can be
quickly determined (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.
27.102.3 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.
Electrical actuators where the motor employs only functional insulation shall comply with
items a) to g) of H.27.1.1.3, 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.
27.102.3.1 During the test, the maximum temperature recorded on insulating parts shall not
exceed 1,5 times the relevant values specified in Clause 14.

+AMD2:2021 CSV © IEC 2021
27.102.4 For electrical 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.
27.102.5 For electrical 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 electrical
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
