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 60794-1-2 has been prepared by subcommittee 86A: Fibres and
cables, of IEC technical committee 86: Fibre optics.
This fifth edition cancels and replaces the fourth edition published in 2017. This edition
constitutes an technical revision.
This edition includes the following significant technical change with respect to the previous
edition:
a) addition of cross-reference tables listing the new test method numbers and the previous test
method numbers.

CDV Report on voting
86A/2009/CDV 86A/2057/RVC

Full information on the voting for the approval of this International Standard can be found in the
report on voting indicated in the above table.
This International Standard is to be used in conjunction with IEC 60794-1-1.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 60794 series, published under the general title Optical fibre cables,
can be found on the IEC website.
The committee has decided that the contents of this document 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 document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or

INTRODUCTION
A decision has been reached to reorganize the IEC 60794-1-2 set of test methods into single-
subject documents. This will be a migration as the existing test methods are revised and as new
test methods are promulgated, rather than a wholesale rewrite. Part of this migration is a
decision to maintain the traditional letter-number classification and to use a numbering system
which maintains connection to the existing numbering system.
The new test method numbering format has been agreed, in line with IEC Secretariat guidelines,
to help the cross-referencing from old to new and that will make the updating of the relevant
sectional and product specifications easier. Cross-reference tables listing the new test method
numbers and the previous test method numbers have been included (see Annex A, Table A.1
to Table A.8).
The format agreed is as follows:
IEC 60794-1-Xnn
where
nd
X = 2 digit of the old 2-digit reference;
nn = incremental number (starting with old test method number).
For example:
IEC 60794-1-21 method E1 (tensile) becomes IEC 60794-1-101;
IEC 60794-1-22 method F5 (water penetration) becomes IEC 60794-1-205;
IEC 60794-1-23 method G7 (tube kinking) becomes IEC 60794-1-307;
IEC 60794-1-24 method H2 (lightning) becomes IEC 60794-1-402.
Annex A has been added to this document containing a cross-reference between the old and
new number scheme.

General guidance



1 Scope
This part of IEC 60794-1 applies to optical fibre cables for use with telecommunications
equipment and devices employing similar techniques, and to cables having a combination of
both optical fibres and electrical conductors.
An objective of this document is to define general requirements and methodology guidance
applicable to all of the cable test methods of IEC 60794-1 (all parts).
A second objective of this document is to provide the end user with an overview of the different
test methods contained in the different parts of the IEC 60794-1 series, numbered -Xnn.
Table 1 shows the different parts.

NOTE 1 The compendium reference specifications detailed in column 3 will continue in force until all of the test
methods therein are revised into the single-subject documents using the new numbering scheme.
NOTE 2 For existing test methods, "nn" is the test method number. For new test methods, "nn" is an incremental
number following the last test method number for that test category.

are historical. To avoid confusion, the existing numb
