21、rldwide 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
22、 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 su
23、bject 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
24、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 C
25、ommittees. 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 w
26、hich 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 Publi
27、cation 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
28、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
29、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 refere
30、nced 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. Interna
31、tional Standard IEC 62052-21 has been prepared by IEC technical committee 13: Equipment for electrical energy measurement and load control. This standard, in conjunction with IEC 62054-11 and IEC 62054-21, cancels and replaces IEC 61038:1990, Electricity metering Tariff and load control Particular r
32、equirements for time switches and all amendments.This standard is to be used in conjunction with the relevant parts of the IEC 62054 and the IEC 62059 series. The text of this standard is based on the following documents: FDIS Report on voting 13/1307/FDIS 13/1316/RVD Full information on the voting
33、for the approval of this standard can be found in the report on voting indicated in the above table. 62052-21 IEC:2004(E) 5 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until
34、 2013. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. A bilingual version of this standard may be issued at a later date. 6 62052-21 IEC:2004(E) INTRODUCTION This standard distinguishes between protective class I and protective class II tarif
35、f and load control 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 informat
36、ion, the relevant parts of IEC 62052, IEC 62054 and IEC 62059 are listed: IEC 62052-21 Electricity metering (a.c.)

40、for the type test of newly manufactured indoor tariff and load control equipment, like electronic ripple control receivers and time switches that are used to control electrical loads, multi-tariff registers and maximum demand indicator devices. This standard gives no requirements for constructional
41、details internal to the tariff and load control equipment. In the case where tariff and load control functionality is integrated into multifunction electricity metering equipment, the relevant parts of this standard apply. This standard does not cover the acceptance tests and the conformity tests. N
42、evertheless, an example of what could be an acceptance test is given in Annex F. The dependability aspect is covered by the documents of the IEC 62059 series. 2 Normative references The following referenced documents are indispensable for the application of this document.
