IEC 61196-1-108:2025 ED3

Coaxial communication cables - Part 1-108: Electrical test methods - Test for phase, phase constant, phase and group delay, propagation velocity, electrical length, and mean characteristic impedance

Scope

IEC 61196-1-108:2025 applies to coaxial communications cables. It specifies test methods for determining the phase, phase constant, phase and group delay, propagation velocity, electrical length, and mean characteristic impedance of coaxial cables for use in communications systems.
A procedure to measure phase dispersion of coaxial cable is included as Annex A.
This third edition cancels and replaces the second edition published in 2011. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Change of title, "phase and phase constant" was added.
b) Clause 6, "Preparation of test sample (TS)" was added.
c) Clause 7, "Test procedure" was added.
d) Clause 8, "Failure criterion" was added.
e) Clause 9, "Information to be given in the relevant specification" was added.
