IEC 61196-1-113:2024

IEC 61196-1-113:2024 applies to coaxial communications cables. It specifies a test method for determining the attenuation constant of coaxial cables for use in communications systems. The test is applicable preferably at frequencies =5 MHz but also for lower frequencies if the magnitude of the complex characteristic impedance is approximately equal to the nominal characteristic impedance of the test sample (TS) or if a form fitting function is applied.
This third edition cancels and replaces the second edition published in 2018. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) add Clause 3 'Terms and definitions';
b) add Clause 4 'Test environment';
c) add Clause 5 'Preconditioning';
d) add Subclause 7.1 'General';
e) add detail test methods including 7.2 'long cable methods' and 7.3 'double-cable method';
f) add 'Annex A Stability of attenuation constant at different temperatures';
g) add 'Annex B Test examples of stability of attenuation constants at different temperature'.
