标准摘要
[中文适用范围]： 本部分IEC 62037定义了辐射被动互调（PIM）测试，用于确定设备或物体在暴露于射频辐射时产生的PIM水平。该测试可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。该测试可在室外测试场地或消声测试室中作为近场或远场测试进行。 [外文原描述]： 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.
