IEC 62153-4-3:2006 Metallic communication cable test methods - Part 4-3: Electromagnetic compatibility (EMC) - Surface transfer impedance - Triaxial method
This test determines the screening effectiveness of a shielded cable by applying a welldefined
current and voltage to the screen of the cable and measuring the induced voltage in
order to determine the surface transfer impedance. This test measures only the magnetic
component of the transfer impedance.
NOTE To measure the electrostatic component (the capacitance coupling impedance), the method described in
IEC 62153-4-82 should be used.
The triaxial method of measurement is suitable in the frequency range up to 30 MHz for a 1 m
sample length and 100 MHz for a 0,3 m sample length, which corresponds to an electrical
length less than 1/6 of the wavelength in the sample.
