标准范围

IEC 62037-8:20 25定义了辐射无源互调（PIM）测试，以确定设备或物体暴露于RF辐射时产生的PIM水平。该测试可以在任何材料或物体上进行，并且不限于设计用于传播RF信号的设备。该试验可作为试验规范定义的近场或远场试验在室外试验场或消声试验室内进行。这第二版取消并取代了2021年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)增加了安全警告，以在连接或断开任何组件之前验证变送器是否已关闭；b)校正后的方向性计算公式；c)图6中校正的天线定向标签；d）增加了PIM测试报告应包括最大PIM和VSWR值的说明。

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.
