EN IEC 60794-1-212:2024

Optical fibre cables - Part 1-212: Generic specification - Basic optical cable test procedures - Environmental test methods - Temperature cycling with cable elements fixed at both ends, Method F12

IEC 60794-1-212:2024 defines the test procedure to examine the attenuation behaviour (change in attenuation) when an optical fibre cable with cable elements fixed at both ends is subjected to temperature cycling. This test assesses the attenuation behaviour of a cable under a no-end movement condition intended for termination with, for example, interconnecting devices or passive components. This document partially cancels and 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) the description of the test method has been changed to “with cable elements fixed at both ends”; b) subclauses have been added to the procedure clause; c) the preparation of cable sample and test set-up has been arranged in a logical way; d) Figure 1 has been added for illustration of the preparation of cable sample, DUT and test set-up; e) the temperature chamber temperature tolerance has been changed to ± 3 °C as done in IEC 60794‑1‑22, method F1; f) all required steps have been added to 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; g) the maximum change in attenuation has been added to the details to be specified; h) a new subclause 4.5 has been added for details to be reported.

Câbles à fibres optiques - Partie 1-212: Spécification générique - Procédures fondamentales d’essais des câbles optiques - Méthodes d’essais d’environnement - Cycle de température avec éléments de câble fixés aux deux extrémités, Méthode F12

IEC 60794-1-212:2024 définit la procédure d’essai pour examiner le comportement en affaiblissement (variation de l’affaiblissement) d’un câble à fibres optiques avec éléments de câble fixés aux deux extrémités soumis à un cycle de température. Cet essai évalue le comportement en affaiblissement d’un câble dont les extrémités ont été bloquées et destiné à être raccordé à des dispositifs d’interconnexion ou des composants passifs, par exemple. Ce 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) modification de la description de la méthode d’essai comme suit: “avec des éléments de câble fixés aux deux extrémités”; b) ajout de paragraphes à l’article relatif à la procédure; c) adaptation de la préparation de l’échantillon de câble et du montage d’essai de manière logique; d) ajout de la Figure 1 pour représenter la préparation de l’échantillon de câble, du DUT et du montage d’essai; e) modification de la tolérance de température de l’enceinte thermostatique à ± 3 °C, comme cela est indiqué dans l’IEC 60794-1-22, méthode F1; f) ajout de toutes les étapes exigées dans le paragraphe relatif au cycle de température, ainsi que le tableau pour déterminer la durée d’exposition minimale et la figure relative à la procédure de cycle, et suppression de la référence à l’IEC 60794-1-22, méthode F1; g) ajout de la variation maximale de l’affaiblissement dans les informations détaillées à spécifier; h) ajout d’un nouveau paragraphe 4.5 pour les informations détaillées à consigner.

Optični kabli - 1-212. del: Splošna specifikacija - Osnovni preskusni postopki za optične kable - Okoljske preskusne metode - Temperaturno cikliranje s kabelskimi elementi, pritrjenimi na obeh koncih, metoda F12 (IEC 60794-1-212:2024)

Standard IEC 60794-1-212:2024 določa preskusni postopek za preučevanje (spremembe) slabljenja, kadar se za optični kabel s kabelskimi elementi, pritrjenimi na obeh koncih, izvede temperaturno cikliranje. S tem preskusom se ocenjuje slabljenje kabla v stanju brez premikov koncev, namenjenega za zaključek z npr. spojnimi elementi ali pasivnimi komponentami. Dokument delno razveljavlja in 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) opis preskusne metode je bil spremenjen v »s kabelskimi elementi, pritrjenimi na obeh koncih«;
b) k točki o postopku so bile dodane podtočke;
c) priprava vzorca kabla in preskusna postavitev sta bili logično urejeni;
d) dodana je bila slika 1 za ponazoritev priprave vzorca kabla, naprave, ki se preskuša (DUT), in preskusne postavitve;
e) toleranca temperature v temperaturni komori je bila spremenjena na ±3 °C (kot v standardu IEC 60794-1-22, metoda F1);
f) 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;
g) podrobnostim, ki jih je treba navesti, je bila dodana največja sprememba slabljenja;
h) dodana je bila nova točka 4.5 za podrobnosti, o katerih je treba poročati.

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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 60794-1-212 has been prepared by subcommittee 86A: Fibres and cables, of IEC technical
committee 86: Fibre optics. It is an International Standard.
