标准摘要
[中文适用范围]： 本部分 IEC 61196 适用于同轴通信电缆。它规定了用于通信系统的同轴电缆的回波损耗（RL）和电压驻波比（VSWR）的测试方法。 [外文原描述]： IEC 61196-1-112:2025 applies to coaxial communications cables. It specifies test methods for determining return loss (RL) and voltage standing wave ratio (VSWR) of coaxial cables for use in communications systems. This second edition cancels and replaces the first edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) added "voltage standing wave ratio" in the title; b) added 3.1 voltage standing wave ratio (VSWR) and 3.2 return loss (RL); c) revised Clause 4 "Principle"; d) added Figure 1 and Figure 2; e) revised Clause 7 "Number of measuring points"; f) added Clause 8 "Test procedure"; g) added Clause 10 "Information to be given in the relevant specification"; h) added Annex B.
