Fibres optiques - Partie 1-32: Méthodes de mesure et procédures d'essai - Dénudabilité du revêtement

La CEI 60793-1-32:2010 est destinée principalement aux essais des fibres, dès leur production par un fabricant de fibres, ou après revêtement ultérieur (revêtement protecteur serré) au moyen de divers polymères. L'essai peut être effectué soit sur des fibres issues de production, soit après exposition à divers environnements. Le présent essai s'applique aux fibres de type A1, A2, A3, B et C. Cette édition a été modifiée pour inclure les pratiques utilisées actuellement sur le marché. Cette publication contient des couleurs qui sont considérés comme étant utile pour une bonne compréhension de son contenu.

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 60793-1-32 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 2001 and constitutes a
technical revision.
This edition has been modified to include current practices in the market place.

OPTICAL FIBRES –
Part 1-32: Measurement methods and test procedures –

Coating strippability
1 Scope
This part of IEC 60793 is intended primarily for testing either fibres as produced by a fibre
manufacturer or subsequently overcoated (tight buffered) using various polymers. The test
can be performed either on fibres as produced or after exposure to various environments.
This test applies to A1, A2, A3, B and C fibres.
The object of this standard is to establish uniform requirements for the mechanical
characteristic – coating strippability. This test quantifies the force required to mechanically
remove the protective coating from optical fibres along their longitudinal axis.
This test is not intended as a means to maximize fibre strength after the coating is removed
nor is it intended to specify the best conditions for field stripping of optical fibres.
This test is designed for optical fibres having polymeric coatings with nominal outer diameters
in the range of 240 μm to 900 μm. Application of this method to fibres with outer coating
diameters outside the range of 230 μm to 930 μm is not recommended.
Warning – Fibres can fracture while being stripped and pierce skin and eyes. Use of
protective eyewear is recommended.
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
of the referenced document (including any amendments) applies.
IEC 60793-1 (all parts), Optical fibres – Measurement methods and test procedures
3 Apparatus
3.1 Tensile equipment
Use a suitable device, for example a vertical tensile tester, which provides relative motion
between the test fibre and a stripping tool and is capable of imparting constant motion at the
velocity found in 5.2, without jerking the fibre under test or the stripping tool.
Use a device capable of providing relative motion in two directions to allow resetting. Provide
suitable means for clamping and maintaining the stripping tool blades perpendicular to the
fibre axis or in a position that prevents fibre bending, and for securing one end of the test
fibre. To prevent fibre breakage, secure the fibre at the clamping point without stressing the
fibre excessively.
Examples of test arrangements are shown in Figure 2.

– 6 – 60793-1-32 © IEC:2010(E)

3.2 Load cell
Use any appropriate device that is capable of sensing the force imparted to the fibre during

the removal of the fibre coating.

3.3 Transducer amplifier
This device receives signals from the load cell and indicates the tensile force on the test fibre
up to the point when the coating is stripped off. The transducer shall acquire the force data at

a rate > 100 Hz. The transducer and/or measurement system shall have the ability to plot the

test data on a continuous chart, such as a strip chart or line chart. It shall also have

the capability of capturing sufficient information to calculate the maximum and average forces,
