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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment
declared to be in conformity with an IEC Publication.
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.

to the tests of 18.101.1 and 18.101.2.
One new sample is used for the tests. After these tests, the energy regulator shall comply with
the requirements of 18.1.5.
18.101.1 Energy regulators with actions classified as type 1.X or 2.X or type 1.Z or 2.Z shall
be subjected to the tests.
– The axial force required to push or pull the actuating member shall not be less than 10 N.
– An axial push or pull force of 140 N applied to the actuating member shall not effect
compliance with 18.1.5.
– For an energy regulator intended for use with a knob having a grip diameter or length of 50
mm or less, the means preventing rotation of the shaft prior to the push or pull actuation
shall withstand, without damage or effect on the energy regulator function, a torque of 4 Nm.
– Alternatively, if the means preventing the rotation of the shaft is defeated when a torque of
at least 2 Nm is applied, the effect shall be such that either:
• the means is not damaged but overridden to close the contacts, in which case
subsequent actuation at a torque less than 2 Nm shall require both push-and-turn or
pull-and-turn to operate the contacts, or
• no operation of the contacts occurs nor can be made to occur.
– The torque required to reset the energy regulator to the initial contact condition, if necessary
after the application of the push or pull, shall not be greater than 0,5 Nm.
– A torque of 6 Nm is applied to the setting means. Any breakage or damage to the means
preventing rotation of the shaft shall not result in failure to comply with the requirements of
Clauses 8, 13 and 20.
– For energy regulators intended for use with a knob having a grip diameter or length greater
than 50 mm, the values of torque are increased proportionally.
18.101.2 Energy regulators with actions classified as type 1.X or 2.X, or type 1.Z or 2.Z shall
be actuated for the declared number of manual cycles.
After this test, the energy regulator shall comply with the requirements of 18.101.1. For the
case in which the means preventing rotation is not damaged but is overridden to operate the
contacts, the first one-sixth of the declared manual cycles shall be performed without first
pushing or pulling the actuating member.
