This part of IEC 60966 is a detail specification that relates to semi-rigid cable assemblies composed of type 50-12 low loss semi-rigid coaxial cable and connectors such as type 7-16 (IEC 61169-4), type 4.1-9.5 (IEC 61169-11), type N (IEC 61169-16), type S7-16 (IEC 61169-53) or type 4.3-10 (IEC 61169-54). It gives subfamily detail requirements and severities which shall be applied.
These cable assemblies are used as jumper cables for mobile communication, mainly used between main feeder and antennas or between main feeder and equipment system or between remote radio heads and antennas. The operating frequency is up to 6 000 MHz.
The qualification will be conducted in accordance with 12.2 of IEC 60966-4:2003. Once one variant obtains qualification approval, the other variant with same cable and connection type can obtain qualification approval by conducting tests whose results might depend on the variants.
Under capability approval, the qualification will be conducted on the relating CQCs (capability qualifying components) as defined in 12.3 of IEC 60966-4:2003 and described in the CM (capability manual). Unless otherwise specified in the CM, only lot-by-lot tests from groups Ba and Eb will be conducted on delivered products, all other tests will be performed on CQCs as defined in 12.3 of IEC 60966-4:2003 and described in the CM.
