IEC 62153-4-16:2016（E）描述了一种方法，分别根据IEC 62153-4-3（方法B）和IEC 62153-4-4使用三轴装置测量时，将传输阻抗的测试结果外推到更高频率，并将屏蔽衰减的测试结果外推到更低频率。IEC 61196-1:1995子条款12.2中已经描述了将转移阻抗的测试结果外推到更高频率的类似方法。该方法适用于均质筛网，即传输阻抗与长度成正比的筛网。传输阻抗可能具有任何频率特性，即，在箔和编织物制成的屏幕上，传输阻抗不会以每十年20 dB的速度增加。

IEC 62153-4-16:2016(E) describes 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 according to IEC 62153-4-3 (method B) respectively IEC 62153-4-4. A similar approach to extrapolate the test results of transfer impedance to higher frequencies was already described in IEC 61196-1:1995 Subclause 12.2. This method is applicable for homogenous screens, i.e. screens having a transfer impedance directly proportional to length. The transfer impedance may have any frequency behaviour, i.e. it could have a behaviour where it does not increase with 20 dB per decade as observed for screens made of a foil and a braid.
