Optical fibre cables - Part 1-307: Generic specification - Basic optical cable test procedures - Cable element test methods - Tube kinking, method G7
IEC 60794-1-307:2025 describes test procedures used in establishing uniform requirements of tubes for the mechanical property kinking. This document applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and to cables having a combination of both optical fibres and electrical conductors. Throughout the document, the wording "optical cable" can also include optical fibre units, microduct fibre units, etc. This first edition partially cancels and replaces the second edition of IEC 60794‑1-23 published in 2019. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to IEC 60794‑1‑23:2019: a) renumbering of the existing test method G7 as G7A; b) addition of test parameter L and calculated loop diameter D in Table 1 for method G7A; c) addition of a new test procedure for tubes routed within installation devices and numbering it as G7B.

IEC 60794-1-307: 2025 décrit les procédures d’essai utilisées afin d'établir des exigences uniformes relatives à la caractéristique mécanique suivante des tubes: pliure. Le présent document s’applique aux câbles à fibres optiques destinés à être utilisés dans les équipements de télécommunication et les dispositifs qui utilisent des techniques analogues, ainsi qu'aux câbles constitués de fibres optiques d'une part et de conducteurs électriques d'autre part. Dans tout le document, l'expression "câble optique" peut également inclure des assemblages de fibres optiques, des assemblages de fibres pour microconduits, etc. Cette première édition annule et remplace partiellement la deuxième édition de l'IEC 60794‑1‑23 parue en 2019. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’IEC 60794‑1‑23:2019: a) renumérotation de la méthode d’essai existante G7 en G7A; b) ajout du paramètre d’essai L et du diamètre de la boucle calculé D dans le Tableau 1 pour la méthode G7A; c) ajout d’une nouvelle procédure d’essai pour les tubes acheminés dans les dispositifs d’installation et numérotation en G7B.

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.
