Overview
IEC 62153-4-13:2009 specifies a laboratory test method for determining the coupling attenuation of links and channels in metallic communication cables, focusing on electromagnetic compatibility (EMC) performance. Using the absorbing clamp method, this standard helps evaluate interference shielding capabilities in both analogue and digital communication systems. Accurate determination of coupling attenuation is essential for ensuring effective signal integrity and minimizing electromagnetic disturbances in high-performance cabling infrastructures.
The methodology outlined in IEC 62153-4-13 is designed for laboratory conditions and is applicable to screened and unscreened, balanced, and unbalanced cable assemblies. This standard is used in conjunction with IEC 62153-4-5, which details the absorbing clamp method for coupling or screening attenuation measurements.
