Optical fibre cables - Part 1-218: Generic specification - Basic optical cable test procedures - Environmental test methods - Mid-span temperature cycling test for exposed optical units, Method F18
IEC 60794-1-218:2025 defines test procedures to establish uniform requirements for the environmental performance of: - optical fibre cables for telecommunication equipment and devices employing similar techniques, and - cables having a combination of both optical fibres and electrical conductors. Throughout this document, the wording "optical cable" can also include optical fibre units, microduct fibre units, etc. This document defines a test standard to determine the ability of optical cable elements from a cable exposed in a mid-span entry (expressed) and stored in a pedestal, closure or similar to withstand the effects of temperature cycling by observing changes in attenuation. The optical cable element bundles up single or multiple optical fibres, e.g. loose tube, tight buffer tube, or optical fibre ribbon. See IEC 60794-1-2 for a reference guide to test methods of all types and for general requirements and definitions. This first edition partially cancels and replaces the second edition of IEC 60794-1-22 published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 60794‑1‑22:2017: a) extension of the test method scope to apply to any optical cables with optical cable elements including loose tubes, tight buffer tubes, and ribbons, exposed in a mid-span entry (expressed) and stored in a pedestal, closure, or similar; b) modification of the test method title according to item a); c) deletion of the tube diameter requirement for the test object; d) modification of the default temperature range according to IEC 60794-1-1; e) addition of the default coiled turns in the assembly during the test.

IEC 60794-1-218: 2025 définit les procédures d’essai utilisées afin d'établir des exigences uniformes applicables aux performances environnementales: - des câbles à fibres optiques pour les équipements de télécommunications et dispositifs utilisant des techniques analogues; et - des câbles constitués de fibres optiques d'une part et de conducteurs électriques d'autre part. Dans le présent document, l'expression "câble optique" peut également inclure des assemblages de fibres optiques, des assemblages de fibres pour microconduits, etc. Le présent document définit une norme d'essai en vue de déterminer la capacité des éléments de câbles optiques d'un câble exposé dans un accès à mi-portée (traversants) et stockés dans une borne, un boîtier ou un dispositif analogue, à résister aux effets des cycles de température en observant les variations de l'affaiblissement. L’élément de câble optique regroupe en faisceau une ou plusieurs fibres optiques, par exemple tube à structure lâche, tube à revêtement de protection serré ou ruban de fibres optiques. Voir l’IEC 60794-1-2 à titre de guide de référence pour les méthodes d'essai de tous les types et concernant les exigences générales et les définitions. Cette première édition annule et remplace partiellement la deuxième édition de l'IEC 60794122 parue en 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) Élargissement du domaine d'application, la méthode d'essai étant applicable à tous les câbles optiques équipés d'éléments de câbles optiques, y compris les tubes à structure lâche, les tubes à revêtement de protection serré et les rubans, exposés dans un accès à mi-portée (traversants) et stockés dans une borne, un boîtier ou dispositif analogue; b) modification du titre de la méthode d'essai conformément au point a); c) suppression de l’exigence pour le diamètre du tube concernant l’objet d’essai; d) modification de la plage de températures par défaut conformément à l’IEC 60794-1-1; e) ajout de spires enroulées par défaut dans le montage pendant l'essai.

27 FOREWORD
28 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
29 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
30 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
31 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
32 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
33 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
34 in the subject dealt with may participate in this preparatory work. International, governmental and non-
35 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
36 with the International Organization for Standardization (ISO) in accordance with conditions determined by
37 agreement between the two organizations.
38 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
39 consensus of opinion on the relevant subjects since each technical committee has representation from all
40 interested IEC National Committees.
41 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
42 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
43 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
44 misinterpretation by any end user.
45 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
46 transparently to the maximum extent possible in their national and regional publications. Any divergence
47 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
48 the latter.
49 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
50 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
51 services carried out by independent certification bodies.
52 6) All users should ensure that they have the latest edition of this publication.
53 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
54 members of its technical committees and IEC National Committees for any personal injury, property damage or
55 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
56 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
57 Publications.
58 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
59 indispensable for the correct application of this publication.
60 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
61 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
62 IEC 60794-1-218 has been prepared by subcommittee 86A: Fibres and cables, of IEC
63 technical committee 86: Fibre optics. It is an International Standard.
64 This first edition of IEC 60794-1-218 cancels and replaces Method F18 of the second edition
65 of IEC 60794-1-22:2017.
66 This edition includes the following significant technical changes with respect to IEC 60794-1-
67 22:2017:
68 a) the scope is broadened that the test method is applicable for any optical cables with
69 optical units including loose tubes, tight buffer tubes, and ribbons, exposed in a mid-span
70 entry (expressed) and stored in a pedestal, closure, or similar;
71 b) change the title of the test method according to the above a);
72 c) delete the tube diameter requirement for the test object;
