This part of IEC 61169@ which is a sectional specification (SS)@ provides information and rules for the preparation of detail specifications (DS) for type 7-16 r.f. coaxial connectors with screw lock. The connectors are normally used with 50 ? flexible and semi-rigid r.f. cables for middle power applications in an operating frequency range up to 7@5 GHz. It describes the interface dimensions for general-purpose grade 2 connectors@ dimensional details for standard test connectors@ grade 0@ together with gauging information and the mandatory tests selected from IEC 61169-1 applicable to all DS relating to type 7-16 connectors. This specification indicates the recommended performance characteristics to be considered when writing a DS and covers test schedules and inspection requirements.
