Optical fibre cables - Part 1-217: Generic specification - Basic optical cable test procedures - Environmental test methods - Cable shrinkage (fibre protrusion), Method F17
IEC 60794-1-217:2024 series defines the test procedure to measure the permanent fibre protrusion compared to the cable elements and cable sheath due to thermal exposure of a cable. This document partially replaces IEC 60794‑1‑22:2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 60794‑1‑22:2017: a) added clarification in the objective that the purpose of this test procedure is to measure the permanent fibre protrusion of cables without rigid strength members; b) replaced the reference to method F1 for the apparatus with a detailed description for the temperature chamber and temperature sensing device as done in IEC 60794-1-211; c) added a measuring device in the subclause for apparatus; d) added conditioning before cutting the cable sample as done in IEC 60794-1-211 e) added all required steps in the subclause for temperature cycling as well as the table for the minimum soak time and the figure for the cycle procedure, and removed the reference to IEC 60794-1-22, method F1; f) improved the figures and added a figure for preparation of the cable sample; g) added the informative Annex A for the test procedure recommended for cables with rigid strength members.

IEC 60794-1-217:2024 définit la procédure d’essai pour mesurer l’excroissance permanente de la fibre par rapport aux éléments de câble et à la gaine de câble, due à l’effet thermique d’un câble. Le présent document remplace partiellement l’IEC 60794-1-22:2017. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’IEC 60794‑1-22:2017: a) précision ajoutée dans l’objectif de cette procédure d’essai qui indique qu’elle vise à mesurer l’excroissance permanente de la fibre sans élément de renfort rigide; b) remplacement de la référence à la méthode F1 pour l’appareillage par une description détaillée de l’enceinte thermostatique et du dispositif de détection de température, comme dans l’IEC 60794-1-211; c) ajout d’un dispositif de mesure dans le paragraphe applicable à l’appareillage; d) ajout du conditionnement avant de couper l’échantillon de câble, comme dans l’IEC 60794‑1-211 e) ajout de toutes les étapes exigées dans le paragraphe relatif au cycle de température, ainsi que de la durée d’exposition minimale et de la figure relative à la procédure de cycle, et suppression de la référence à l’IEC 60794-1-22, méthode F1; f) amélioration des figures et ajout d’une figure pour la préparation de l’échantillon de câble; g) ajout de l’Annexe A informative pour la procédure d’essai recommandée pour les câbles avec éléments de renfort rigides.

Skupina standardov IEC 60794-1-217:2024 določa preskusni postopek za merjenje trajne izbočenosti vlaken v primerjavi s kabelskimi elementi in plaščem zaradi izpostavljenosti kabla toploti. Dokument delno nadomešča standard IEC 60794‑1‑22:2017. Ta izdaja je tehnično popravljena izdaja. Ta izdaja v primerjavi s standardom IEC 60794-1-22:2017 vključuje naslednje pomembne tehnične spremembe:
a) v cilju je bilo dodano pojasnilo, da je namen tega preskusnega postopka merjenje trajne izbočenosti kabelskih vlaken brez togih elementov;
b) sklic na metodo F1 za naprave je bil zamenjan s podrobnim opisom temperaturne komore in naprave za zaznavanje temperature (kot v standardu IEC 60794-1-211);
c) v podtočki o napravah je bila dodana merilna naprava;
d) dodano je bilo kondicioniranje pred rezanjem vzorca kabla (kot v standardu IEC 60794-1-211);
e) v podtočko o temperaturnem cikliranju, preglednico o minimalnem času namakanja in sliko postopka cikliranja so bili dodani vsi zahtevani koraki ter odstranjen je bil sklic na standard IEC 60794-1-22, metoda F1;
f) slike so bile izboljšane in dodana je bila slika za pripravo vzorca kabla;
g) dodan je bil informativni dodatek A za preskusni postopek, priporočen za kable s togimi elementi.

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 sh
