IEC 61196-1-112 ED2

Coaxial communication cables - Part 1-112: Electrical test methods - Test for return loss and voltage standing wave ratio IEC 61196-1-112 ED2

Scope

IEC 61196-1-112:2025 applies to coaxial communications cables. It specifies test methods for determining return loss (RL) and voltage standing wave ratio (VSWR) of coaxial cables for use in communications systems.
This second edition cancels and replaces the first edition published in 2006. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) added "voltage standing wave ratio" in the title;
b) added 3.1 voltage standing wave ratio (VSWR) and 3.2 return loss (RL);
c) revised Clause 4 "Principle";
d) added Figure 1 and Figure 2;
e) revised Clause 7 "Number of measuring points";
f) added Clause 8 "Test procedure";
g) added Clause 10 "Information to be given in the relevant specification";
h) added Annex B.
