标准摘要
[中文适用范围]： IEC 62037-8:2025 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 62037-8:2025 定义了辐射无源互调 (PIM) 测试，以确定设备或物体暴露于射频辐射时产生的 PIM 水平。此测试可以在任何材料或物体上进行，不限于设计用于传播射频信号的设备。此测试可以作为测试规范定义的近场或远场测试在室外测试场地或消声室中进行。第二版取消并取代 2021 年发布的第一版。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) 增加了安全警告，以验证在连接或断开任何组件之前已关闭发射器；b) 更正了计算方向性的公式； c) 更正了图 6 中的天线方向标签；d) 补充说明 PIM 测试报告应包括最大 PIM 和 VSWR 值。 [外文原描述]： IEC 62037-8:2025 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 62037-8:2025 defines a radiated passive intermodulation (PIM) test to determine PIM levels generated by a device or object when it is exposed to RF radiation. This test can be conducted on any material or object and is not limited to devices designed to propagate RF signals. This test can be conducted as either a near field or far field test as defined by the test specification in an outdoor test site or in an anechoic test chamber. This second edition cancels and replaces the first 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) added safety warning to verify that transmitters are switched off before connecting or disconnecting any component; b) corrected formula for calculating directivity; c) corrected antenna orientation labels in Figure 6; d) added clarification that PIM tests reports shall include maximum PIM and VSWR values.
