标准摘要
[中文适用范围]： IEC 61196的本部分适用于同轴通信电缆。它规定了确定通信系统中使用的同轴电缆衰减常数的测试方法。该测试优选适用于 5 MHz 频率，但如果复特性阻抗的幅度约等于样本的标称特性阻抗或者如果应用形状拟合函数，则也适用于较低频率。 [外文原描述]： IEC 61196-1-113:2018(E) applies to coaxial communications cables. It specifies a test method for determining the attenuation constant of coaxial cables for use in communications systems. The test is applicable preferably at frequencies ≥ 5 MHz, but also for lower frequencies if the magnitude of the complex characteristic impedance is approximately equal to the nominal characteristic impedance of the specimen or if a form fitting function is applied. This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: diverse form fitting equations are provided.
