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.

Standard IEC 60794-1-308: 2023 opisuje preskusne postopke za ocenjevanje stopnje stalnega zavoja v nekabelskem traku ali v kabelskem traku iz optičnih vlaken. Dokument obravnava trakove iz optičnih vlaken za uporabo s telekomunikacijsko opremo in napravami, ki uporabljajo podobne tehnike, ter trakove iz optičnih vlaken v kablih s kombinacijo optičnih vlaken in električnih vodnikov. Ta dokument se ne uporablja za delno vezane trakove. Ta metoda za delno vezane trakove je v pripravi. V dokumentu lahko izraz »optični kabel« vključuje tudi optične enote, mikrokanale itd. OPOMBA Okoljsko preskušanje traku iz optičnih vlaken je lahko koristno za nekatere vrste uporabe. Koristne informacije o ustreznih preskusnih metodah so na voljo v standardih za optična vlakna IEC 60793-1-50, IEC 60793‑1‑51, IEC 60793 in IEC 60793-1-53.

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 deal
