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 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
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 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.

INTRODUCTION
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 clauses 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 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 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 several 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.

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 preparation 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 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
requirements 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
editorial 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 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 standard when revision will be
needed in the future.
This document also lists the available blocks and modules which were prepared for RCD
product standards.

4 Methodology
4.1 General
The process for harmonization of clauses 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
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 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 module 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 achieve this work
could be applied.
– 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
feedback 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 SC 23E secretary in order to be used when drafting standards.
The module is given an IEC number (see 4.2.4) and it is circulated as an INF document
(e.g. 23E/XXX/INF).
4.2.3 Preparation of a block
A harmonized clause which is intended to be a block will follow the IEC rules for drafting
standards. It is intended to be published as an IEC standard to which it will be possible to
refer (e.g. terms and definitions for RCDs).
4.2.4 Numbering of documents and edition numbers
Table 1 specifies the numbering given to the documents prepared within the methodology of
blocks and modules.

4.2.5 Module for figures and module for tables
A module containing all the figures is prepared in order to have consistent figures in all the
standards. This module provides a unique number to each figure.
A module containing all the tables is prepared in order to have consistent tables in all the
standards. This module provides a unique number to each table.
4.3 Assembly of a standard
4.3.1 General
When preparing a standard based on the blocks and modules approach, the following are
taken into consideration:
– the modules are copied in the draft document, where relevant;
– a table of modules used in the standard is introduced in an informative annex;
– the standard may make reference to other standards (blocks), where applicable;
– non-harmonized clauses may be introduced where relevant.

The draft document then follows the IEC Directives for voting process.
The process for assembly of a standard is shown in Figure 2.
4.3.2 Introduction of modules
The necessary modules are introduced in the draft document by copying the content of the
module for a given clause. If a module contains an indication that a paragraph or a subclause
is not applicable, then this paragraph or this subclause is removed from the draft.
NOTE All the indications or secretary notes in the module, such as “The following text highlighted in grey applies
to RCCB only.”, are removed when assembling the standard.
The abbreviation PCBM is replaced by the relevant abbreviation: RCD, or RCCB, or RCBO, .
When introducing a module in a standard, the reference and the edition of the module shall be
indicated in a table situated in an informative annex. An example of such a table is provided
in Table 2 below.
Table 2 – Example of table for correspondence between clauses
and modules used in this standard
Clause(s) Module/block Number Edition/date Remarks
1 Not harmonized – –
2 Not harmonized – –
3 Block IEC 62873-2 1.0
4 Module Module XXX yyyy/mm 23E/ZZZ/INF
5 Module Module YYY yyyy/mm 23E/ZZZ/INF

4.3.3 Reference to other standards
The reference to other standards (blocks) is made in the draft document where and when
necessary. The reference is a dated reference in order to avoid that a modification to a
referred standard would impact compliance with the standard itself.
The standards which are referred to are also listed in the clause for normative references.
4.3.4 Non-harmonized clauses
When and where relevant, non-harmonized clauses may be introduced, in the case where no
specific module exists for such a clause. When a non-harmonized clause is introduced, if a
similar non-harmonized clause is used in another standard, it is possible that some
inconsistencies will exist between those two standards.
In Table 2, a non-harmonized clause is mentioned as “Not harmonized”.
4.3.5 Figures and tables
When introducing the figures, the module for figures (see 4.2.5) is used, and each necessary
figure is copied in the standard with its unique number. In the case where a figure is not
needed in a given standard, the figure will not be copied in the standard. Figures keep the
number given in the module for figures; as a consequence, the figure numbers in the standard
will not be contiguous. Figures not used will be mentioned as “Void”.
When introducing the tables, the module for tables (see 4.2.5) is used, and each necessary
table is copied in the standard with its unique number. In the case where a table is not

– 10 – IEC 62873-1:2017  IEC 2017
needed in a given standard, the table will not be copied in the standard. Tables keep the
number given in the module for tables; as a consequence, the table numbers in the standard
will not be contiguous. Tables not used will be mentioned as “Void”.
Tables and figures are introduced systematically at the end of a document, therefore avoiding
linking them with a particular clause.
4.3.6 Voting and commenting process
The blocks and modules approach only defines a methodology to prepare standards in order
to avoid inconsistencies or mistakes and to accelerate the drafting process. Therefore, when
the assembly of the standard is completed, the document (Working Draft) follows the IEC
Directives for comment and vote (see ISO/IEC Directives, Part 1 and ISO/IEC Directives,
IEC Supplement).
Any change in a harmonized clause during the commenting and voting process shall be re-
introduced in the corresponding module.
4.4 Revision of a standard using blocks and modules
4.4.1 General
For the revision of a standard using the modules in the library of the secretary, it is necessary
to introduce the modification in the standard and in the relevant module in order to keep track
of the modification for further application in other standards using this module. The process in
4.4.2 to 4.4.4 shall be complied with.
4.4.2 Modification of the relevant module (step 1)
It is recommended to introduce the necessary modification in the relevant module in a first
step. This introduction will allow verifying that the modification is consistent with the other
standards using this module. However, a revised module cannot be issued in the library of the
secretary until the modification is accepted by NCs.
4.4.3 Introduction of the revised module in the standard (step 2)
In a second step, the revised module will be introduced in the standard which needs to be
revised. This process will follow the process defined in 4.3, but only for the clause of the
standard which needs to be modified.
NOTE It is possible to achieve the steps 1 (see 4.4.2) and 2 at the same time.
4.4.4 Other standards using this module
If another standard uses this module, it need not be automatically revised. But as the module
was updated and is kept in the library of modules, when the revision of this standard is
decided, this modification will be introduced.
EXAMPLE:
Standard A, standard B and standard C were assembled using module approach.
The decision to revise standard A is taken, because subclause 5.3 of this standard needs to be revised.
Nevertheless, the decision to revise standards B and C is not taken because these standards were already revised
recently.
Subclause 5.3 of standard A is modified and standard A follows the usual IEC procedure for comments and vote.
Once the modifications have been accepted by NCs, a new Module 5.3 is issued and introduced in the library of the
secretary.
Later on, when the decision to revise standard B or C is taken, the new Module 5.3 will be introduced.

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (IEC) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l’IEC). L’IEC a pour
objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines
de l'électricité et de l'électronique. A cet effet, l’IEC – entre autres activités – publie des Normes
internationales, des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au
public (PAS) et des Guides (ci-après dénommés "Publication(s) de l’IEC"). Leur élaboration est confiée à des
comités d'études, aux travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les
organisations internationales, gouvernementales et non gouvernementales, en liaison avec l’IEC, participent
également aux travaux. L’IEC collabore étroitement avec l'Organisation Internationale de Normalisation (ISO),
selon des conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de l’IEC concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l’IEC
intéressés sont représentés dans chaque comité d’études.
3) Les Publications de l’IEC se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de l’IEC. Tous les efforts raisonnables sont entrepris afin que l’IEC
s'assure de l'exactitude du contenu technique de ses publications; l’IEC ne peut pas être tenue responsable de
l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de l’IEC s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de l’IEC dans leurs publications nationales
et régionales. Toutes divergences entre toutes Publications de l’IEC et toutes publications nationales ou
régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) L’IEC elle-même ne fournit aucune attestation de conformité. Des organismes de certification indépendants
fournissent des services d'évaluation de conformité et, dans certains secteurs, accèdent aux marques de
conformité de l’IEC. L’IEC n'est responsable d'aucun des services effectués par les organismes de certification
indépendants.
6) Tous les utilisateurs doivent s'assurer qu'ils sont en possession de la dernière édition de cette publication.
7) Aucune responsabilité ne doit être imputée à l’IEC, à ses administrateurs, employés, auxiliaires ou
mandataires, y compris ses experts particuliers et les membres de ses comités d'études et des Comités
nationaux de l’IEC, pour tout préjudice causé en cas de dommages corporels et matériels, ou de tout autre
dommage de quelque nature que ce soit, directe ou indirecte, ou pour supporter les coûts (y compris les frais
de justice) et les dépenses découlant de la publication ou de l'utilisation de cette Publication de l’IEC ou de
toute autre Publication de l’IEC, ou au crédit qui lui est accordé.
8) L'attention est attirée sur les références normatives citées dans cette publication. L'utilisation de publications
référencées est obligatoire pour une application correcte de la présente publication.
9) L’attention est attirée sur le fait que certains des éléments de la présente Publication de l’IEC peuvent faire
l’objet de droits de brevet. L’IEC ne saurait être tenue pour responsable de ne pas avoir identifié de tels droits
de brevets et de ne pas avoir signalé leur existence.
La Norme internationale IEC 62873-1 a été établie par le sous-comité 23E: Disjoncteurs et
appareillage similaire pour usage domestique, du comité d'études 23 de l'IEC: Petit
appareillage.
Le texte de cette norme est issu des documents suivants:
