BS EN IEC 62153-4-5:2021

What is IEC 62153-4-5 about? 

IEC 62153-4-5 discusses an absorbing clamp method. This method is suitable to determine the screening- or the coupling-attenuation of metallic communication cables in the frequency range of 30 MHz to 1 000 MHz (2 400 MHz), depending on the performance of the clamp. It is an alternative method to the triaxial method of IEC 62153-4-4 or IEC 62153-4-9. Due to the undefined outer circuit of this absorbing clamp method, the test results obtained at different places and laboratories could vary by at least ± 6 dB. 

Who is IEC 62153-4-5 for? 

IEC 62153-4-5 on metallic communication cables is applicable to: 

• Transmission line for radio frequency signals 
• Computer network (e.g., Ethernet) Connections 
• Digital audio (S/PDIF) 
• Cable television

Why should you use IEC 62153-4-5? 

IEC 62153-4-5 helps to determine the screening- or the coupling-attenuation of metallic communication cables which helps improve cables efficiency and quality of the signal transmitted. 

The absorbing clamp method is described in IEC 62153-4-5 to determine the screening- or coupling-attenuation for a given frequency in order to protect metallic communication cables. which helps metallic communication cables durability and Long service-life 

What’s changed since the last update? 

BS EN IEC 62153-4-5:2021 cancels and replaces the first edition published in 2006. This version of IEC 62153-4-5 constitutes a technical revision.  

BS EN IEC 62153-4-5:2021 includes the following significant technical changes with respect to the previous edition: 

• Reorganisation of clauses and annexes 
• Extension of the frequency range to 2,4 GHz 
• Application of a virtual balun respectively balunless test procedure with multiport VNA
