Part 2-12: Particular requirements for
electrically operated door locks

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 60730-2-12 has been prepared by technical committee 72:
Automatic electrical controls.
This third edition cancels and replaces the second edition published in 2005. This edition
constitutes a technical revision. This edition includes the following significant technical changes
with respect to the previous edition:
a) aligns the text with IEC 60730-1, Edition 5;
b) modifies requirements for Class B control function (H.27.1.2.2);
c) modifies requirements for Class C control function (H.27.1.2.3);

AUTOMATIC ELECTRICAL CONTROLS –

Part 2-12: Particular requirements for
electrically operated door locks

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 60730-2-12 has been prepared by technical committee 72:
Automatic electrical controls.
This third edition cancels and replaces the second edition published in 2005. This edition
constitutes a technical revision. This edition includes the following significant technical
changes with respect to the previous edition:
a) aligns the text with IEC 60730-1, Edition 5;
b) modifies requirements for Class B control function (H.27.1.2.2);
c) modifies requirements for Class C control function (H.27.1.2.3);
d) modifies requirements for faults during safety shut-down.

27.101 Test with disconnected phase on three phase electrically operated door locks
with motors
27.101.1 With any one phase disconnected, the electrically operated door lock with
motors 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 test
27.102.1 A running overload test is carried out on electrically operated door locks with
motors 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.
27.102.2 The door lock is operated under normal operating condition, carrying its rated load
and supplied at rated voltage until the temperature of the motor windings stabilizes. The
protector or protective method shall not operate or open the circuit while the door lock is
operating under the above conditions.
27.102.2.1 For all electrically operated door locks with motors where the maximum trip
point in the sensing variable is not known or cannot be quickly determined (for example,
temperature sensing method, impedance protected motors, sensor-less motor protection
methods, position sensing, etc.), the load to the door lock 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 function under this overload
condition, the load to the door lock is again increased by 10 % of the previous load setting
and the door lock 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 door lock is then run at this maximum 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 electrically operated door locks with motors where the maximum trip point
in the sensing variable is known or can be quickly determined (for example, current sensing
methods), the load to the door lock is gradually increased, in a controlled manner, until the
protective device or protective circuit is activated. This is the load cut-off point and the
loading parameters (torque, current, etc.) shall be measured and recorded. Then, the load is
decreased slowly from the load cut-off point until the protector or protective circuit is not
activated. The door lock is then run at this maximum load until the temperature of the winding
stabilizes.
NOTE A brake dynamometer may be used to gradually increase the torque on the door lock shaft in a controlled
manner.
27.102.3 During the test, the maximum winding temperature prior to the functioning 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.
NOTE If the load cannot be increased in appropriate steps, the motor and the protective electronics, if applicable,
may be removed from the door lock assembly and tested separately.
27.102.3.1 During the test, the maximum temperature recorded on insulating parts that
directly supports the motor shall not exceed 1,5 times the relevant values specified in
Clause 14.
