12、C 2017 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ RESIDUAL CURRENT OPERATED CIRCUIT-BREAKERS FOR HOUSEHOLD AND SIMILAR USE Part 1: Outline of blocks and modules for residual current device standards FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for st
13、andardization 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
14、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 partic
15、ipate 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 betw
16、een 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 Publicatio
17、ns 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 an
18、y 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
19、 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 conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any serv
20、ices 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 directors, employees, servants or agents including individual experts and members of its technical committees and IEC Nat
21、ional 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
22、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 sha
23、ll not be held responsible for identifying any or all such patent rights. International Standard IEC 62873-1 has been prepared by subcommittee 23E: Circuit breakers and similar equipment for household use, of IEC technical committee 23: Electrical accessories. The text of this standard is based on t
24、he following documents: CDV Report on voting 23E/945/CDV 23E/988/RVC Full information on the voting for the approval of this International Standard can be found in the report on voting indicated in the above table.

At this date, the document will be reconfirmed, withdrawn, replaced by a revised edition, or amended. BS IEC 62873-1:2017IEC 62873-1:2017 IEC 2017 5 INTRODUCT
27、ION When revising standards within the same group of standards (e.g. RCCBs, RCBOs), it can be clearly seen that there are some common clauses (e.g. reliability of terminals, markings), some clauses with limited differences and some clauses that are completely different (e.g. short-circuit test claus
28、es for RCCBs and RCBOs). In many cases, there are some mistakes or inconsistencies in clauses which should be identical. Moreover, during each revision, some modifications are made in a document and not systematically introduced in the other documents of the same group of standards, thus leading to
29、new inconsistencies or mistakes. In addition, there are also some significant differences between IEC TR 60755 and IEC 61008-1 or IEC 61009-1, although these three standards should be consistent. In consultation with the IEC Central Office, SC 23E developed a new approach allowing the production of
30、short papers dealing with only one topic (e.g. one clause of a standard) in order to improve the efficiency of the work and to avoid the many mistakes and discrepancies introduced within the standards over the years. A template was agreed for producing this work. This approach was launched with seve
31、ral clauses in order to avoid the mistakes and the discrepancies within clauses which should be similar or identical. This document defines the objectives of this approach, the scope, the methodology and the processes. This document constitutes also a summary of the blocks and modules. BS IEC 62873-
32、1:2017 6 IEC 62873-1:2017 IEC 2017 RESIDUAL CURRENT OPERATED CIRCUIT-BREAKERS FOR HOUSEHOLD AND SIMILAR USE Part 1: Outline of blocks and modules for residual current device standards 1 Scope The IEC 62873 series covers available common standards intended to be used in conjunction with or for the pr
33、eparation of RCD (residual current device) standards. This part of IEC 62873 defines the methodology and processes used when producing standards based on a new approach (hereafter referred to as blocks and modules) aiming at harmonizing a family of standards, thus avoiding mistakes, inconsistencies
34、or discrepancies within this family of standards. The family of standards considered in this document consists of standards for RCCBs (Residual Current Circuit-Breakers without overcurrent protection), RCBOs (Residual Current Circuit-Breakers with overcurrent Protection), and general safety requirem
35、ents for residual current operated protective devices (namely IEC 61008-1, IEC 61009-1 and IEC TR 60755). This approach defines a way to optimize drafting of standards, aiming to keep a common or similar structure, to have common clauses (as far as possible), to avoid inconsistencies, to do editoria
36、l work only once, to speed up production of standards, to ensure that a comment on one clause in one standard is also taken into account in other standards, if needed. The principles of the blocks and modules approach are: to identify those parts of the standards which need to be identical (or with
37、limited differences), and those parts of the standards which should remain different; to set a library of those common parts; to identify the parts which should be published as stand-alone standards; to draft product standards, using the library; to keep track of the common parts used in a product s
38、tandard when revision will be needed in the future. This document also lists the available blocks and modules which were prepared for RCD product standards. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirem

ISO and IEC maintain terminological databases for use in standardization at the following addresses: IEC Electropedia: available at http:/www.electropedia.org/ ISO Online br
42、owsing platform: available at http:/www.iso.org/obp 3.1 harmonized clause clause whose content is common to several standards 3.2 module harmonized clause intended to be copied and assembled in a product standard Note 1 to entry: Modules may be partially harmonized (e.g. part applicable to RCCB only
43、). Note 2 to entry: Modules are kept in the SC 23E secretary library. 3.3 block harmonized and self-standing clause(s), referred to in a product standard and published as a separate standard (e.g. glossary for definitions for all RCDs) 4 Methodology 4.1 General The process for harmonization of claus
44、es and preparation of a module or a block is explained in Figure 1. 4.2 Harmonization of clauses 4.2.1 Drafting of a harmonized clause Preparation of a harmonized clause requires the following tasks to be performed: comparison of the same clauses within the family of standards where harmonization is
45、 being done and proposal if those clauses may be harmonized; drafting of the harmonized clause for the given family of standards, using the specific template. In case a paragraph is only applicable to a specific standard, this is indicated above the paragraph. revision of the harmonized clause by a
46、task force of one or two experts and then analysis of the result of by an ad hoc group; proposals from task forces and ad hoc group are then submitted to SC 23E for decision regarding this harmonized clause. The decisions taken by SC 23E cover technical and editorial aspects and circulation as a mod
47、ule or as a block. NOTE 1 Clauses are harmonized first and later become either a block or a module. NOTE 2 The process defined above is achieved by task forces and by an ad hoc group. This is a choice within SC 23E in order to accelerate the process for creation of harmonized clauses; other means to
48、 achieve this work could be applied. BS IEC 62873-1:2017 8 IEC 62873-1:2017 IEC 2017 4.2.2 Preparation of a module A harmonized clause which is intended to be a module needs to be prepared in the following way: circulation as Document for Comments (DC) to National Committees (NCs) in order to get fe
49、edback from countries regarding the technical content of the module; decisions from SC 23E regarding the comments provided by the NCs and introduction of the agreed comments in the module. This document is circulated as an INF document. In case there is significant modification in the module, a second DC may be circulated to NCs for comments; the module is then edited by IEC Central Office to comply with IEC drafting rules and is then kept in the library of
