IEC 61196-1-113:2018(E) 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 specimen or if a form fitting function is applied.
This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition: diverse form fitting equations are provided.
