IEC 60364-5-56:2009

Low-voltage electrical installations - Part 5-56: Selection and erection of electrical equipment - Safety services

IEC 60364-5-56:2009 covers general requirements for safety services, selection and erection of electrical supply systems for safety services and electrical safety sources. Standby electrical supply systems are outside the scope of this part. This part does not apply to installations in hazardous areas (BE3), for which requirements are given in IEC 60079-14. This second edition of IEC 60364-5-56 comes about as a result of changes to Clause 556, Safety services, of IEC 60364-5-55 (2001), as modified by its amendment 1 (2001). It replaces Clause 556 of IEC 60364-5-55:2001. Clause 556 is to be withdrawn at the time of publication of this new Part 56. The main changes with regard to the previous edition are listed below:
1) Many more definitions are included, e.g. response time, central power supply system, low power supply system, preferential circuit and escape route.
2) Automatic supplies are now classified according to the maximum changeover times, for example a supply classified as short break means an automatic supply is available within 0,5 s.
3) Safety sources that can operate in parallel are specifically recognized in 560.6.9.
4) Requirements are now given for batteries used for safety sources for central and low power supply sources.
5) Drawings are now required, such as a single-line diagram, drawings showing the location of equipment and a list of equipment permanently connected to the safety power supply.
6) Operating instructions are now required.
7) Detailed requirements are now given for emergency escape lighting applications, direct current circuits and fire protection applications.
8) Additional requirements for initial verification and periodic inspection and testing are now included in the standard.
9) Two annexes are now included (Annex A and Annex B) giving guidance for emergency lighting and guidance for fire protection equipment, respectively.

La CEI 60364-5-56:2009 traite des exigences générales relatives aux services de sécurité, au choix et à la mise en oeuvre des alimentations électriques des installations et des sources de sécurité. Les alimentations électriques de remplacement ne sont pas traitées dans la présente partie. Cette partie ne s'applique pas aux installations dans les zones à risque d'explosion (BE3) pour lesquelles des exigences sont données dans la CEI 60079-14. Cette deuxième édition de la CEI 60364-5-56 est issue de la révision de l'Article 556, Installations de sécurité, de la CEI 60364-5-55 (2001), telle que modifiée par son amendement 1 (2001). Elle remplace l'Article 556 de la CEI 60364-5-55 :2001. L'Article 556 est à supprimer à la date de la publication de cette nouvelle Partie 56. Les principales modifications par rapport à l'édition précédente sont les suivantes:
1) Plus de définitions incluses, par exemple, temps de réponse, source centrale d'alimentation, source d'alimentation de faible puissance, circuit préférentiel et chemin d'évacuation.
2) Les alimentations automatiques sont maintenant classées selon le temps de commutation, par exemple, une alimentation classée arrêt court signifie que l'alimentation automatique reprend en 0,5 s.
3) Les sources de sécurité pouvant fonctionner en parallèle sont spécifiquement indiquées en 560.6.9.
4) Les exigences pour les batteries employées comme sources centrales de sécurité ou de faibles puissances sont maintenant indiquées.
5) Des schémas sont maintenant requis, tel qu'un schéma unifilaire, d'implantation des matériels et une liste des matériels connecté en permanence à la source de sécurité.
6) Un mode d'emploi est maintenant requis.
7) Des exigences détaillées sont maintenant données pour l'éclairage d'évacuation, les circuits en courant continu et la protection incendie.
8) Des exigences complémentaires pour les vérifications initiales et périodiques ainsi que les essais sont incluses dans la norme.
9) Deux annexes ont été ajoutées (l'Annexe A et l'Annexe B) afin de donner les lignes directrices pour l'éclairage de sécurité et les matériels de protection incendie.

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 60364-5-56 has been prepared by IEC technical committee 64:
Electrical installations and protection against electric shock.
This second edition of IEC 60364-5-56 comes about as a result of changes to Clause 556,
Safety services, of IEC 60364-5-55 (2001), as modified by its amendment 1 (2001).
This new part replaces Clause 556 of IEC 60364-5-55:2001. Clause 556 is to be withdrawn at
the time of publication of this new Part 56.
The main changes with regard to the previous edition are listed below:
1) Many more definitions are included, e.g. response time, central power supply system, low
power supply system, preferential circuit and escape route.
___________
The first edition of IEC 60364-5-56, which was published in 1980, together with its amendment (1998), was
withdrawn when its contents were incorporated into the first edition of IEC 60364-5-55.

2) Automatic supplies are now classified according to the maximum changeover times, for

example a supply classified as short break means an automatic supply is available within

0,5 s.
3) Safety sources that can operate in parallel are specifically recognized in 560.6.9.

4) Requirements are now given for batteries used for safety sources for central and low

power supply sources.
5) Drawings are now required, such as a single-line diagram, drawings showing the location

of equipment and a list of equipment permanently connected to the safety power supply.

6) Operating instructions are now required.

7) Detailed requirements are now given for emergency escape lighting applications, direct
current circuits and fire protection applications.
8) Additional requirements for initial verification and periodic inspection and testing are now
included in the standard.
9) Two annexes are now included (Annex A and Annex B) giving guidance for emergency
lighting and guidance for fire protection equipment, respectively.
The text of this standard is based on the following documents:
FDIS Report on voting
64/1677/FDIS 64/1686/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The reader’s attention is drawn to the fact that Annex C lists all of the “in-some-country”
clauses on differing practices of a less permanent nature relating to the subject of this
standard.
A list of all parts in the IEC 60364 series, under the general title Low-voltage electrical
installations, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result 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.
