24、IONAL FUNCTION(S) 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 stan

25、dardization 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 preparat

26、ion 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 wit

27、h 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 subj

28、ects 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

29、 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 p

30、ossible 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 conf

31、ormity 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 dire

32、ctors, 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 arisin

33、g 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 dr

34、awn 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. The main task of IEC technical committees is to prepare International Standards. However, a technical committ

35、ee may propose the publication of a technical report when it has collected data of a different kind from that which is normally published as an International Standard, for example “state of the art“. IEC TR 62710, which is a Technical Report, has been prepared by subcommittee 23E: Circuit- breakers

36、and similar equipment for household use, of IEC technical committee 23: Electrical accessories. The text of this standard is based on the following documents: Enquiry draft Report on voting 23E/875/DTR 23E/900/RVC Full information on the voting for the approval of this technical report can be found

37、in the report on voting indicated in the above table. IEC TR 62710:2015 IEC 2015 5 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. In this Technical Report, the following print types are used: compliance statements: in italic type The committee has decided that t

38、he contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A biling

39、ual version of this publication may be issued at a later date. 6 IEC TR 62710:2015 IEC 2015 INTRODUCTION This Technical Report (TR) introduces information allowing manufacturers to introduce additional function(s) associated with Residual current devices (RCD). This TR is also relevant for technical

40、 committees in charge of drafting an International Standard for additional function(s); for this purpose, requirements and tests have been introduced. It would also be of benefit to laboratories having difficulties in testing RCDs associated with an additional function. This TR does not cover the ad

41、ditional function(s) itself (this is the purpose of an International Standard covering the additional function(s), nor the RCD function and characteristics (this is the purpose of an RCD International Standard). It is limited to checking that the additional function(s) do not impair any function of

42、the RCD in case there is no International Standard for the additional function(s) for household and similar uses. Where there is a relevant International Standard for household and similar uses for the additional function(s), then it is used. This means that the assembly of the RCD plus the addition

43、al function(s) behave correctly according to the referred standards. This Technical Report is drafted according to the following basic principles: In order not to restrict innovation, it is drafted independently of the additional function(s) and is thus applicable whatever the additional function(s)

44、 are. NOTE It is not possible to list all possible existing and future additional function(s); some examples are given within the definitions. The verification is only limited to the assembly and association of an RCD with one or several additional function(s), being integrated or not. The verificat

45、ion aims to show that the assembly of one or several additional function(s) declared suitable to a specific protective device is safe and does not impair the basic characteristics of the RCD. Responsibility for the assembly means that the additional function(s) and the RCD are intended to be from th

46、e same manufacturer or to be affixed with the same trademark. As a consequence, it is intended that the manufacturer or trademark owner declare with which protective devices the additional function(s) can be associated. IEC TR 62710:2015 IEC 2015 7 RESIDUAL CURRENT DEVICES (RCDs) ASSOCIATED WITH ADD

47、ITIONAL FUNCTION(S) 1 Scope This Technical Report (TR) provides information concerning the possible use of: dedicated additional function(s) declared by a manufacturer as suitable for an assembly with declared RCDs complying with IEC standards for household and similar uses; specific RCDs complying

48、with IEC standards for household and similar uses having integrated additional function(s). NOTE 1 The term RCD is a generic term applied to a family of products which open automatically in response to a residual current at or exceeding the RCDs rated residual operating current I n . This generic te

49、rm is often applied to the following: RCCB: Residual current operated circuit-breaker without integral overcurrent protection; RCBO: Residual current operated circuit-breaker with integral overcurrent protection; SRCD: Residual current device with or without overcurrent protection for socket-outlets; PRCD: Portable residual current device without integral overcurrent protection. This TR identifies the applicable testing procedure to determine the effect on the normal functioning of specific RCD(s)
