同轴通信电缆 第1-111部分：电气试验方法 相位稳定性试验方法

[中文适用范围]： 本部分IEC 61196提供了测定同轴通信电缆相位稳定性的测试方法。 本文件适用于射频同轴电缆。射频同轴电缆组件也可参考本文件。 本部分IEC 61196包含以下测试方法： a) 温度引起的相位变化（第4条）； b) 温度引起的相位常数变化（第5条）； c) 弯曲引起的相位稳定性（第6条）； d) 扭转引起的相位稳定性（第7条）； e) 两根或更多电缆的相位一致性测试（附录A）； f) 两根电缆间温度引起的相位变化测试（附录B）。 [外文原描述]： IEC 61196-1-111:2024 provides test methods to determine the stability of phase of coaxial communication cables. This document is applicable to RF coaxial cables. RF coaxial cable assemblies can also use this document for reference. This part of IEC 61196 comprises following test methods: a) phase variation with temperature (Clause 4); b) phase constant variation with temperature (Clause 5); c) phase stability with bending (Clause 6); d) phase stability with twisting (Clause 7); e) phase consistency test for two or more cables (Annex A); f) phase variation with temperature test between two cables (Annex B). This second edition cancels and replaces the first edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of the list of test methods in the Scope; b) addition of "the number of scanning points" in every test method; c) addition of Annex A, Phase consistency test for two or more cables; d) addition of Annex B, Phase variation with temperature test between two cables.
