Latest version of optical cable friction test standard

The latest standard for optical cable friction testing is IEC 60794-1-130:2025.OverviewIEC 60794-1-130:2025 specifies test procedures to determine the coefficient of dynamic friction of optical fibre cable sheathing when pulled over or between other cables . This standard applies to optical fibre cables used in telecommunications and hybrid cables containing both optical fibres and electrical conductors . The term "optical cable" also encompasses optical fibre units and microduct fibre units.Test MethodsThe standard defines two primary methods for evaluating friction:Method E30A (Drum Test): Measures the coefficient of friction when a cable is pulled over the top of other cables.Method E30B (Flat Plate Test): Measures the coefficient of friction when a cable is pulled between other cables of the same shape . These methods allow manufacturers and installers to assess cable behavior during installation, ensuring safe and efficient deployment.Revisions and UpdatesIEC 60794-1-130:2025 replaces Method E24 from the first edition of IEC 60794-1-21 published in 2015, including Amendment 1:2020 . This edition constitutes a technical revision, updating procedures and clarifying the scope for modern optical fibre and hybrid cables.ApplicabilityThe standard is relevant for:Telecommunication optical fibre cablesHybrid cables with both optical and electrical conductorsOptical fibre units and microduct fibre units used in similar installation techniques It ensures consistent measurement of friction properties, which is critical for cable installation, especially in complex duct or aerial deployments.AccessIEC 60794-1-130:2025 is available for purchase as a PDF or XML digital download from authorized distributors such as BSI, DIN Media, and other standards organizations . Digital licenses allow access on multiple devices, typically up to three, with additional licenses available if needed.
