标准摘要
[中文适用范围]： IEC 62037-3:2025 RLV 包含官方 IEC 国际标准及其红线版本。红线版本仅提供英文版，可让您快速轻松地比较官方 IEC 标准与之前版本之间的所有更改。IEC 62037-3:2025 定义了对同轴连接器的冲击试验，以评估其对连接器内部弱连接和颗粒的坚固性，尽可能独立于电缆无源互调 (PIM) 的影响。对于其他连接器（例如面板安装连接器），可以用合适的传输线（例如航空线、带状线）代替电缆。为了评估机械应力对连接器的影响，在测量 PIM 的同时对连接器施加了一系列冲击。第三版取消并取代了 2021 年发布的第二版。此版本构成技术修订。此版本与上一版相比包括以下重大技术变化：a) 增加了对多通道连接器的冲击试验要求； b) 计算除圆形以外的连接器形状所附加的冲击能量的方法；c) 修改了在反向（反射）PIM 测量中实现最大 PIM 的测试考虑因素；d) 补充说明 PIM 测试报告应包括测得的最大 PIM 值。 [外文原描述]： IEC 62037-3:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62037-3:2025 defines the impact test on coaxial connectors to evaluate their robustness against weak connections and particles inside the connector, as independently as possible from the effects of cable passive intermodulation (PIM). For other connectors (e.g. panel mounted connectors), the cable can be replaced by an adequate transmission line (e.g. airline, stripline). In order to evaluate the effects of mechanical stresses on the connectors, a series of impacts is applied to the connectors while measuring the PIM. This third edition cancels and replaces the second edition published in 2021. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) impact test requirements for multi-channel connectors added; b) method for calculating impact energy added for connector shapes other than round; c) revised test considerations for achieving maximum PIM in reverse (reflected) PIM measurements; d) added clarification that PIM tests reports shall include the maximum PIM value measured.
