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".
