prEN IEC 60794-1-118:2026

This part of IEC 60794-1 describes test procedures to be used in establishing uniform requirements for optical fibre cables for the mechanical property – bending under tension. The purpose of this test is to determine the ability of an optical fibre cable to withstand bending around rollers or bows during installation, when a specified load is applied.
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.
See IEC 60794-1-2 for a reference guide to test methods of all types and for general requirements. Throughout the document, the wording "optical cable" can also include optical fibre units, microduct fibre units, etc.
