标准摘要
[中文适用范围]： 本标准规定了同轴通信电缆的电气测试方法，涵盖相位、相位常数、相位和群延迟、传播速度、电长度以及平均特性阻抗的测试。适用于长电缆和短电缆的测试，并提供了测试设备、测试样品准备、测试程序、故障判据等相关信息。 [外文原描述]： 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.
