It is identical with IEC 60169-21 : 1985, including Amendment 1 : 1996. The UK participation in its preparation was entrusted by Technical Committee
4、EPIJ46, Cables, wires and waveguides, r.f. connectors and accessories for communication and signalling, to Subcommittee EPIJ46/2, Connectors and waveguides, which has the responsibility to: - aid enquirers to understand the text; - present to the responsible internationaUEuropean committee any enqui
5、ries on the interpretation, or proposals for change, and keep the UK interests informed - monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. From 1 January 1997,
6、all IEC publications have the number 60000 added to the old number. For instance, IEC 27-1 has been renumbered as IEC 60027-1. For a period of time during the change over from one numbering system to the other, publications may contain identifiers from both systems. Cross-references Attention is dra
7、wn to the fact that CEN and CENELEC standards nonnally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement these international or European publications may be found in the BSI Standarcis

Scope This specification standardizes the interface and ratings of two versions of a medium size r.f. con- nector for use with flexible and semi-rigid cables. The connectors are recommended to be utilized in
27、 medium power and low reflection applications up to 11 GHz. The dielectric filled interface is espe- cially beneficial in applications involving severe environmental exposure.
