IEC 62153-4-16:20 21规定了一种方法，当根据IEC 62153-4-3、IEC 62153使用三轴装置测量时，将传输阻抗的测试结果外推到较高频率，将屏蔽衰减的测试结果外推到较低频率？4？4和IEC 62153-4-15。该方法适用于均质筛网，即具有与长度成正比的转移阻抗的筛网。 这第二版取消并取代了2016年出版的第一版。与上一版相比，此版本包括以下重大技术变更: -用适用于任何负载条件的新转换公式替换仅限于匹配DUT的转换公式。

IEC 62153-4-16:2021 specifies a method to extrapolate the test results of transfer impedance to higher frequencies and the test results of screening attenuation to lower frequencies when measured with the triaxial set-up in accordance with IEC 62153-4-3, IEC 62153？4？4 and IEC 62153-4-15. This method is applicable for homogenous screens, i.e. screens having a transfer impedance directly proportional to length.
This second edition cancels and replaces the first edition published in 2016. This edition includes the following significant technical changes with respect to the previous edition:
- replacement of the conversion formula which was limited to a matched DUT by a new conversion formula suitable for any load conditions.
