L'IEC 62054-21:2004 spécifie les exigences particulières pour l'essai de type d’horloges de tarification dont la production est nouvelle, prévues pour un usage sous abri, avec une réserve de marche et qui sont utilisées pour la commande de charges électriques, de registres multitarifs et d’indicateur de maximum d’équipements de comptage électrique La présente version bilingue (2016-12) correspond à la version anglaise monolingue publiée en 2004-05.
Merjenje električne energije (a.c./izmenični tok) – Krmiljenje tarif in bremen – 21. del: Posebne zahteve za časovna stikala (IEC 62054-21:2004)
Ta del standarda IEC 62054 določa posebne zahteve za tipsko preskušanje novo proizvedenih notranjih časovnih stikal z delovno rezervo, ki se uporabljajo za krmiljenje električnih obremenitev, večtarifnih registrov in indikatorjev maksimuma, za opremo za merjenje električne energije.
Časovno stikalo ohranja realni čas, lahko tudi datum, morda lahko upošteva prestopna leta, podpira poletni čas, tj. prilagodi odstopanje lokalnega časa glede na GMT v skladu z ustreznimi predpisi. Časovno stikalo lahko vključuje zmogljivost sinhronizacije.
Časovno stikalo vsebuje tudi razpored preklopov, ki se lahko določijo glede na čas, dan v tednu in datum v mesecu ali letu. Časovno stikalo nadzoruje izhodne elemente glede na čas in razpored shranjenih preklopov.
V tem standardu niso podane zahteve za konstrukcijske podrobnosti časovnega stikala.
Kadar je funkcija časovnega stikala vgrajena v večfunkcijsko opremo za merjenje električne energije, se uporabljajo ustrezni deli tega standarda.
Ta standard zajema časovna stikala z analognimi mehanskimi številčnicami ali elektronskimi digitalnimi zasloni, ki so:
– sinhroni; ali
– kristalni.
Ta standard ne obravnava preskusov sprejemljivosti in skladnosti. Kljub temu je primer preskusa sprejemljivosti podan v dodatku A.
Vidik zanesljivosti je zajet v dokumentih iz skupine standardov IEC 62059.
Pri uporabi tega standarda skupaj s standardom IEC 62052-21 imajo zahteve tega standarda prednost pred zahtevami standarda IEC 62052-21 glede katerega koli elementa, ki ga že obravnava.

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.
International Standard IEC 62054-21 has been prepared by IEC technical committee 13:
Equipment for electrical energy measurement and load control.
This standard, in conjunction with IEC 62052-21, cancels and replaces IEC 61038:1990,
Electricity metering – Tariff and load control – Particular requirements for time switches and
all amendments. .
This standard is to be used in conjunction with IEC 62052-21 and the relevant parts of the IEC
62059 series.

(Replaces the particular requirements of IEC 61037.)
IEC 62054-21: Particular requirements for time switches
(Replaces the particular requirements of IEC 61038.)
The committee has decided that the contents of this publication will remain unchanged until
2013. At this date, the publication will be
• reconfirmed;
• withdrawn;

INTRODUCTION
This standard distinguishes between protective class I and protective class II equipment
The test levels are regarded as minimum values to guarantee the proper functioning of the
equipment under normal working conditions. For special application, other test levels might be
necessary and should be agreed on between the user and the manufacturer.
For information, the relevant parts of IEC 62052, IEC 62054 and IEC 62059 are listed below.
