LOW-VOLTAGE ELECTRICAL INSTALLATIONS –

Part 7-718: Requirements for special installations or locations –
Communal facilities and workplaces

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.
International Standard IEC 60364-7-718 has been prepared by IEC technical committee 64:

INTRODUCTION
The particular requirements of this part of IEC 60364 supplement, modify or replace certain of
the general requirements contained in Parts 1 to 6 of IEC 60364.
The clause numbering appearing after 718 refers to the corresponding parts or clauses of
IEC 60364, Parts 1 to 6 . Numbering of clauses does not, therefore, necessarily follow
sequentially. Numbering of additional text is shown by the addition of “.101, etc.”. Numbering
of figures and tables takes the number of this part followed by a sequential number. For
annexes, the numbering of figures and tables takes the letter of the annex, the number of the
part and a sequential number.
The absence of reference to a part or clause means that the general requirements contained
in Parts 1 to 6 of IEC 60364 are applicable.

———————
For historical reasons, IEC 60364-1:2005 numbering is as follows: 11 Scope; 12 Normative references; 20
Terms and definitions, etc.

– meeting places, swimming halls, airports, railway stations, high-rise buildings;
– workshops, factories and industrial plants.
Access routes and escape routes are part of the above-mentioned examples.
The necessity of providing safety services in special buildings and areas may be governed by
national regulations which may contain more stringent requirements.
NOTE For safety services see IEC 60364-5-56.
718.2 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition

– Locations with low risk: single normal lighting final circuit.
NOTE 2 This is valid for code BD1 in Table 51A.
– Other locations: two or more normal lighting final circuits with luminaires supplied in such
a way that failure of any one circuit will not leave any part of the location with an
insufficient level of illumination.
If RCDs are used no RCD shall protect more than one final circuit.
NOTE 3 This is valid for codes BD2 to BD4 in Table 51A.
NOTE 4 Emergency lighting circuits as required can be added to either option.
718.559.101.2 If the normal lighting of a location accessible to the public can be dimmed,
means shall be provided to reinstate the full level of illumination by an appropriately located
switch.
NOTE In areas such as some places of entertainment it may be necessary to ensure lighting cannot be operated
by unauthorized persons.
