Optical fibres - Part 1-30: Measurement methods and test procedures - Fibre proof test
IEC 60793-1-30:2010 describes procedures for briefly applying a specified tensile load as a proof test to continuous lengths of optical fibre. The tensile load is applied for as short a time as possible, yet sufficiently long to ensure the glass experiences the proof stress, typically much less than one second. This method is applicable to types A1, A2, A3 and B optical fibres. The main change with respect to the previous edition is an improved description of the procedure.
Fibres optiques - Partie 1-30: Méthodes de mesure et procédures d'essai - Essais de sélection
IEC 60793-1-30:2010 décrit des procédures permettant d'appliquer brièvement, à titre d'essai de sélection, une force de traction déterminée à la totalité de la longueur d'une fibre optique. La force de traction est appliquée sur une durée aussi courte que possible, mais suffisamment longue toutefois pour garantir que le verre supporte les essais de contrainte, généralement quelques dixièmes de moins d'une seconde. Cette méthode est applicable aux fibres optiques de types A1, A2, A3 et B. Le but de la présente norme est d'établir des exigences uniformes applicables aux essais de sélection des caractéristiques mécaniques des fibres. Cette deuxième édition annule et remplace la première édition, publiée en 2001, dont elle constitue une révision technique. Le changement principal par rapport à l'édition précédente est une description améliorée de la procédure.

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 60793-1-30 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.
The main change with respect to the previous edition is an improved description of the
procedure.

Fibre proof test
1 Scope
This part of IEC 60793 describes procedures for briefly applying a specified tensile load as a
proof test to continuous lengths of optical fibre. The tensile load is applied for as short a time
as possible, yet sufficiently long to ensure the glass experiences the proof stress, typically
much less than one second.
This method is applicable to types A1, A2, A3 and B optical fibres.
The object of this standard is to establish uniform requirements for the mechanical
characteristic fibre proof test.
2 Normative references
None.
3 Apparatus
3.1 General
There are several possible machine designs, all of which perform the basic functions required
for measuring fibre proof with the indicated general operating requirements. Care should be
used in the design so as to prevent coating damage.
Two machine types are used:
– braked capstan type;
– dead weight type.
Either machine may be used during the fibre-drawing process (on-line for coated fibre only),
or as a separate process step (off-line).
NOTE There are dynamics with on-line screening, (different from off-line screening), which should be taken into
account.
3.2 Fibre pay out
Isolate the tensile load variations from the proof test region so as not to cause variations in
the proof load. Do not permit the applied proof stress to fluctuate below the value specified in
the detail specification.
3.3 Proof test region
With the exception of additional bend stress of up to 10 % of the proof stress, apply the proof
stress uniformly through the cross-sectional area of the test sample. Ensure that the load-
bearing members in this region are rigid (e. g. made of steel or aluminium). During testing, the
tension-producing mechanism(s) shall not allow the proof stress to fluctuate below the value
specified in the detail specification.
60793-1-30 © IEC:2010(E) – 7 –
Proof testing requires that a constant stress be applied sequentially along the full length of
fibre. A break rate (failures per unit length) is statistically expected. It is carried out during
fibre manufacturing, on-line as part of the fibre drawing and coating process, or off-line as
part of the testing process.
The stress history of proof test stressing is as follows:
• stress loading from near-zero to the proof test stress during a load time;
• constant proof test stress during a dwell time;
• stress unloading from the proof test stress back down to near-zero during an unload
time.
3.4 Fibre take-up
Isolate the tensile load variations from the proof test region so as not to cause variations in
the proof load. Ensure that the applied proof stress does not fluctuate below the value
specified in the detail specification.
3.5 Load and unload
The load and unload regions occur on both sides of the proof test region. Tension in the fibre
ramps up from being under constant low tension, in the pay-out region, to the full load in the
proof
