[中文适用范围]： 本部分 IEC 61169 是一个分规范（SS），提供了关于 HD-BNC 系列射频同轴连接器的详细规范（DS）编写信息及规则，并附有空白详细规范范本。HD-BNC 系列连接器特性阻抗为 75 Ω，用于微波、电信、无线及其他领域的射频电缆或微带线。工作频率上限为 18 GHz。还规定了通用连接器的配合面尺寸、量规信息以及从 IEC 61169-1 中选择的适用于所有 HD-BNC 系列射频连接器详细规范的测试。本规范指出了编写详细规范时应考虑的推荐性能特性，并涵盖了评估级别 M 和 H 的测试计划和检查要求。 [外文原描述]： IEC 61169-70:2024, which is a sectional specification (SS), provides information and rules for the preparation of detail specifications (DS) of HD-BNC series RF coaxial connectors together with the pro forma blank detail specification. HD-BNC series connectors with characteristic impedance of 75 Ω are used with RF cables or micro-strips in microwave, telecommunication, wireless and other fields. The operating frequency limit is up to 18 GHz. It also prescribes mating face dimensions for general purpose connectors, gauging information and tests selected from IEC 61169-1, applicable to all detail specifications relating to series HD-BNC RF connectors. This specification indicates the recommended performance characteristics to be considered when writing a detail specification and it covers test schedules and inspection requirements for assessment levels M and H.
