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 60446 has been prepared by IEC technical committee 16: Basic
and safety principles for man-machine interface, marking and identification.
This fourth edition cancels and replaces the third edition, published in 1999 and constitutes a
technical revision. This edition includes the following significant technical changes with
respect to the previous edition:
a) addition of Clause 3 – Terms and definitions
b) addition of Clause 4 – Identification of conductors
c) addition of subclauses 5.3.4 to 5.3.6 – Use of bi-colour combinations
d) addition of subclause 6.2 – Identification of certain designated conductors
e) addition of a new Annex A (informative) “Identification of certain designated conductors by
means of colour code and alphanumeric”
f) deletion of the old Annex A (informative) “Methods of marking PEN conductors in different
countries”.

INTRODUCTION
This International Standard is a basic safety publication is intended for use by technical
committees in the preparation of standards in accordance and with the principles laid down in
IEC Guide 104 and in ISO/IEC Guide 51.
It should be noted that one of the responsibilities of a technical committee is, wherever
possible, to include or refer to requirements of basic safety publications in standards for
equipment within its scope. Consequently, the requirements of this basic safety publication
apply only if they are included, or are referred to in those standards.

IDENTIFICATION OF CONDUCTORS BY COLOURS OR ALPHANUMERICS



1 Scope
This International Standard provides general rules for the use of certain colours or
alphanumerics to identify conductors with the aim of avoiding ambiguity and ensuring safe
operation. These conductor colours or alphanumerics are intended to be applied in cables or
cores, busbars, electrical equipment and installations.
