金属电缆和其他无源元件试验方法第4-15部分:电磁兼容性（EMC）用三轴电池测量传输阻抗和屏蔽衰减或耦合衰减的试验方法

[中文适用范围]： 本部分IEC 62153规定了使用三轴室测量连接器、电缆组件和组件（例如模拟和数字传输系统的配件，以及通信网络和布线设备）的转移阻抗、屏蔽衰减或耦合衰减的程序。测量可以通过将被测设备直接应用于三轴室来实现，或者根据IEC 62153-4-7使用管中管方法来实现。 [外文原描述]： IEC 62153-4-15:2021 specifies the procedures for measuring with triaxial cell the transfer impedance, screening attenuation or the coupling attenuation of connectors, cable assemblies and components, for example accessories for analogue and digital transmission systems, and equipment for communication networks and cabling. This second edition cancels and replaces the first edition published in 2015.This edition includes the following significant technical changes with respect to the previous edition: a) measurement of coupling attenuation of balanced connectors, assemblies and components with balun and balunless added; b) application of a test adapter was added; c) application of a moveable shorting plane; d) application of the triaxial "absorber" cell; e) correction of test results in the case that the receiver input impedance R is higher than the characteristic impedance of the outer circuit Z2.
