IEC 62153-4-5 Ed. 1.0 b:2006
Metallic communication cables test methods - Part 4-5: Electromagnetic compatibility (EMC) - Coupling or screening attenuation - Absorbing clamp method
determines the coupling or screening attenuation of metallic communication cables in the frequency range of 30 MHz to 1 000 MHz. It is an alternative method to the injection clamp method of IEC 62153-4-3 or the triaxial method of IEC/ PAS 62338. 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 Ý6dB.
