ELECTRICITY METERING (AC)–
TARIFF AND LOAD CONTROL –
Part 21: Particular requirements for time switches
1 Scope
This part of IEC 62054 specifies particular requirements for the type test of newly
manufactured indoor time switches with operation reserve that are used to control electrical
loads, multi-tariff registers and maximum demand devices of electricity metering equipment.
The time switch keeps the real time, it may keep the date, it may be capable of handling leap
years, it may support daylight saving, i.e. it modifies the deviation of local time to GMT
according to the relevant regulations. The time switch may have a synchronization capability.
The time switch also holds a schedule of switching actions, which may be specified in terms
of time, day of the week, date within a month or a year. The time switch controls the output
elements depending on the time and the schedule of switching actions stored.
This standard gives no requirements for constructional details internal to the time switch.
In the case where time switch functionality is integrated into multifunction electricity metering
equipment, the relevant parts of this standard apply.
This standard covers time switches with analogue mechanical dials or electronic digital
displays that are
– synchronous; or
– crystal-controlled.
This standard does not cover the acceptance tests and the conformity tests. Nevertheless, an
example of what could be an acceptance test is given in Annex A .
The dependability aspect is covered by the documents of the IEC 62059 series.
When using this standard in conjunction with IEC 62052-21, the requirements of this standard
take precedence over those of IEC 62052-21 with regard to any item already covered in it.

Part 21: Particular requirements for time switches
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.
This consolidated version of the official IEC Standard and its amendment has been prepared
for user convenience.
