INTERNATIONAL ELECTROTECHNICAL COMMISSION

LOW VOLTAGE ELECTRICAL INSTALLATIONS –
Part 6: Verification
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 60364-6 has been prepared by the IEC technical committee 64:
Electrical installations and protection against electric shock.
This third edition cancels and replaces the second edition published in 2016 and constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Normative references updated to current publications;
b) Annex E: New model forms for reporting;
c) Annex F: New model inspection schedules
d) Annex G: New schedule of circuit details and schedule of test results
e) Annex H: Recommended period before the first periodic verification initial frequencies of
inspection of electrical installations
f) Annex I: Periodic verification of an electrical installation in dwellings

g) Annex J: Listing of notes concerning some countries;
h) Bibliography – Updated:
The text of this standard is based on the following documents:
FDIS Report on voting
64/xxxx/FDIS 64/xxxx/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.
A list of all parts in the IEC 60364 series, published under the general title Low voltage electrical
installations, can be found on the IEC website.
The reader's attention is drawn to the fact that Annex J lists all of the “in-some-country” clauses
on differing practices of a less permanent nature relating to the subject of this standard.
The committee has decided that the contents of this publication will remain unchanged until the
stability date indicated on the IEC web site 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.
IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates that it
contains colours which are considered to be useful for the correct understanding of its
contents. Users should therefore print this document using a colour printer.

3 Part 6: Verification
7 6.1 Scope
8 This part of IEC 60364 provides requirements for initial and periodic verification of an electrical
9 installation.
10 It provides requirements for initial verification, by inspection and testing, of an electrical
11 installation to determine, as far as reasonably practicable, whether the requirements of parts 1,
12 4, 5 and 8 of IEC 60364 have been met, and requirements for the reporting of the results of the
13 initial verification. The initial verification takes place upon the completion of a new electrical
14 installation or completion of an addition or an alteration to an existing electrical installation.
15 It provides requirements for periodic verification of an electrical
