Optical fibre cables - Part 1-308: Generic specification - Basic optical cable test procedures - Cable element test methods - Ribbon residual twist test, method G8

IEC 60794-1-308: 2023 describes test procedures to evaluates the degree of permanent twist in an uncabled ribbon or in a cabled optical fibre ribbon. This document applies to optical fibre ribbons in optical cables for use with telecommunication equipment and devices employing similar techniques, and to optical fibre ribbons in cables having a combination of both optical fibres and electrical conductors. This document is not applicable to partially-bonded ribbons. The method for partially-bonded ribbons is under consideration. Throughout the document, the wording "optical cable" can also include optical fibre units, microduct fibre units, etc. NOTE The environmental testing of optical fibre ribbon would be valuable for some applications. Useful information about suitable test methods can be found in the optical fibre standards IEC 60793-1-50, IEC 60793‑1‑51, IEC 60793‑1‑52, and IEC 60793-1-53.

Câbles à fibres optiques - Partie 1-308: Spécification générique - Procédures fondamentales d'essais des câbles optiques – Méthodes d'essai des éléments de câbles – Essai de torsion résiduelle du ruban, méthode G8

IEC 60794-1-308: 2023 décrit les procédures d'essai visant à évaluer le degré de torsion permanente dans un câble à fibres optiques en ruban relié ou non relié. Le présent document s’applique aux rubans de fibres optiques dans les câbles optiques destinés à être utilisés dans les équipements de télécommunications et les dispositifs qui utilisent des techniques similaires, ainsi qu'aux rubans de fibres optiques dans les câbles qui combinent à la fois des fibres optiques et des conducteurs électriques. Le présent document ne s’applique pas aux rubans collés partiellement. La méthode relative aux rubans collés partiellement est à l’étude. Dans tout le document, l'expression "câble optique" peut également inclure des assemblages de fibres optiques, des assemblages de fibres pour microconduits, etc. NOTE Les essais d’environnement appliqués au ruban de fibres optiques sont susceptibles d’être particulièrement utiles dans le cas de certaines applications. Des informations utiles liées aux méthodes d'essais appropriées sont fournies dans les normes relatives aux fibres optiques IEC 60793-1-50, IEC 60793‑1‑51, IEC 60793‑1‑52 et IEC 60793-1-53.

26 FOREWORD

27 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

28 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

29 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

30 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

31 Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their

32 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

33 may participate in this preparatory work. International, governmental and non-governmental organizations liaising

34 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

35 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

36 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

37 consensus of opinion on the relevant subjects since each technical committee has representation from all

38 interested IEC National Committees.

39 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

40 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

41 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

42 misinterpretation by any end user.

43 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

44 transparently to the maximum extent possible in their national and regional publications. Any divergence between

45 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

46 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

47 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

48 services carried out by independent certification bodies.

49 6) All users should ensure that they have the latest edition of this publication.

50 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

51 members of its technical committees and IEC National Committees for any personal injury, property damage or

52 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

53 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.

54 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

55 indispensable for the correct application of this publication.

56 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subjec
