IEC 61156-7:2023
Multicore and symmetrical pair/quad cables for digital communications - Part 7: Symmetrical pair cables with transmission characteristics up to 1 200 MHz - Sectional specification for digital and analogue communication cables
Product Details
a. align clauses with IEC 61156-1:2023;
b. remove the clause related to screening attenuation as it is no longer a test to be performed (replaced by coupling attenuation);
c. replace the IEC 62153-4-2 method (injection clamp) with IEC 61156-4-5 (absorbing clamp) for coupling attenuation measurement to be consistent with all other parts of the IEC 61156 series;
d. include IEC 62153-4-9 test method (triaxial) for coupling attenuation measurement to be consistent with all other parts of the IEC 61156 series;
e. incorporate the blank detail specification.
