SRPS EN IEC 60794-1-307:2025

Optical fibre cables - Part 1-307: Generic specification - Basic optical cable test procedures - Cable element test methods - Tube kinking, method G7

Scope

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.
