Optical fibre cables - Part 1-126: Generic specification - Basic optical cable test procedures - Mechanical tests methods - Galloping, Method E26
IEC 60794-1-126:2026 defines the test procedures used to establish uniform requirements for mechanical performance - galloping. It applies to optical fibre cables like ADSS, OPGW or OPPC that can be exposed to galloping phenomena. See IEC 60794-1-2 for general requirements and definitions and for a complete reference guide to test methods of all types. This first edition cancels and replaces Method E26 of the first edition of IEC 60794‑1‑21 published in 2015. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition:a) Addition of " for ADSS" and " for OPGW and OPPC" in 4.7, a) b) Addition of " L4" in Figure 1 and in 4.7, b) c) Change of the specified static sag angle to ≤ 1,5±0,5° d) Improvement of Figure 1
