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 60794-1-23 has been prepared by subcommittee 86A: Fibres and
cables, of IEC technical committee 86: Fibre optics.This second edition cancels and replaces the first edition published in 2012. It constitutes a
technical revision.This edition includes the following significant technical changes with respect to the previous
edition:a) addition of a new test method G9: Bleeding and evaporation (formerly known as
method E15 in IEC 60794-1-21:2015);
b) addition of a new test method G10A: Stripping force stability of cabled optical fibres
(formerly known as method E5A in IEC 60794-1-21:2015);c) addition of a new test method G10B: Strippability of optical fibre ribbons (formerly known
as method E5B in IEC 60794-1-21:2015);d) addition of a new test method G10C: Strippability of buffered optical fibres (formerly known

148 FOREWORD
149 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
150 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
151 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
152 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
153 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
154 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
155 in the subject dealt with may participate in this preparatory work. International, governmental and non-
156 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
157 with the International Organization for Standardization (ISO) in accordance with conditions determined by
158 agreement between the two organizations.159 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
160 consensus of opinion on the relevant subjects since each technical committee has representation from all
161 interested IEC National Committees.162 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
163 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
164 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
165 misinterpretation by any end user.166 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
167 transparently to the maximum extent possible in their national and regional publications. Any divergence
168 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
169 the latter.170 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
171 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
172 services carried out by independent certification bodies.173 6) All users should ensure that they have the latest edition of this publication.
174 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
175 members of its technical committees and IEC National Committees for any personal injury, property damage or
176 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
177 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
178 Publications.179 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
180 indispensable for the correct application of this publication.181 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
182 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
183 International Standard IEC 60794-1-23 has been prepared by subcommittee 86A: Fibres and
184 cables, of IEC technical committee 86: Fibre optics.185 This edition of IEC 60794-1-23 cancels and replaces the first edition published in 2012. It
186 constitutes a technical revision.187 This edition includes the following significant technical changes with respect to the previous
188 edition:189 a) addition of a new test Method G9: Bleeding and evaporation (formerly known as
190 Method E15 in IEC 60794-1-21:2015);191 b) addition of a new test Method G10A: Stripping force stability of cabled optical fibres
192 (formerly known as Method E5A in IEC 60794-1-21:2015);193 c) addition of a new test Method G10B: Strippability of optical fibre ribbons (formerly known
194 as Method E5B in IEC 60794-1-21:2015);---------------------- Page: 7 ----------------------

226 1 Scope
227 This part of IEC 60794 describes test procedures to be used in establishing uniform
228 requirements for the geometrical, material, mechanical, environmental properties of optical
229 fibre cable elements.230 This document applies to optical fibre cables for use with telecommunication equipment and
231 devices employing similar techniques, and to cables having a combination of both optical
232 fibres and electrical conductors.233 Throughout the document, the wording “optical cable” can also include optical fibre units,
234 microduct fibre units, etc.235 See IEC 60794-1-2 for a reference guide to test methods of all types and for general
236 requirements and definitions.237 NOTE The environmental testing of optical fibre ribbon would be valuable for some applications. Useful
238 information about suitable test methods can be found in the fibre series IEC 60793-1-50 - 53.
