Anotace

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".
