IEC 62153-4-7:2021
IEC 62153-4-7:2021 deals with the triaxial tube in tube method. This triaxial method is suitable to determine the surface transfer impedance and/or screening attenuation and coupling attenuation of mated screened connectors (including the connection between cable and connector) and cable assemblies. This method could also be extended to determine the transfer impedance, coupling or screening attenuation of balanced or multipin connectors and multicore cable assemblies. This third edition cancels and replaces the second edition published in 2015 and its Amendment 1:2018.This edition includes the following significant technical changes with respect to the previous edition: - Annex E contains informative information about the direct measurement of screening effectiveness of connectors; - Annex F gives normative information about mixed mode parameters; - Annex G contains normative information about accessories for measuring coupling attenuation; - Annex H discusses the low frequency screening attenuation.
