It describes important background material used during the revision of IEC 61196-1:1995, Clause 14, Guidance for surface transfer impedance and screening attenuation limits for flexible r.f. cables. It is also given the relationship between surface transfer impedance (ZT) and screening attenuation (as), also measurements of ZT and as are provided to show the correlation of mean screening attenuation between 200 MHz and 500 MHz and ZT at both 30 MHz and 300 MHz. Il fournit les informations generales utiles utilisees au cours de la revision de la CEI 61196-1:1995, Article 14, Instructions pour limpedance de transfert en surface et les limites daffaiblissement decran pour les cables r.f. souples. Il est egalement donnee la relation entre limpedance en transfert en surface (ZT) et laffaiblissement decran (as) ; de meme, les mesures de ZT et as sont fournies pour montrer la correlation de laffaiblissement moyen de lecrantage entre 200 MHz et 500 MHz et ZT a 30 MHz et 300 MHz.
