IEC 61196-1-108:2025适用于同轴电缆。它规定了确定通信系统中使用的同轴电缆的相位、相位常数、相位和群延迟、传播速度、电气长度和平均特性阻抗的测试方法。测量同轴电缆相位色散的程序包括在附录A中。这第三版取消并取代了2011年出版的第二版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a）标题变更，增加了“相和相常数”。b)增加第6条“供试品（TS）的制备”。c)第7条增加了“试验程序”。d)第8条，增加“失效标准”。e)增加第9条“相关规范中应提供的信息”。

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.
