23、 4 RADIO FREQUENCY AND COAXIAL CABLE ASSEMBLIES Part 4: Sectional specification for semi-rigid coaxial cable assemblies 1 Scope This part of IEC 60966 is a sectional specification that relates to semi-rigid coaxial cable assemblies operating in the transverse electromagnetic mode (TEM). It establish
24、es uniform requirements for testing the electrical, mechanical and climatic properties of semi-rigid cable assemblies composed of semi-rigid coaxial cables and coaxial connectors. NOTE 1 The numbering of the Clauses is the same as in the generic specification. NOTE 2 For the purpose of this sectiona
25、l specification, a cable assembly is always regarded as an integral unit. All specifications apply to the finished assembly and not to individual and non-assembled parts thereof. NOTE 3 This sectional specification should be supplemented with detail specifications giving additional details as requir
26、ed by the particular application. This application will not necessarily require all tests. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest editio
27、n of the referenced document (including any amendments) applies.

30、Cables should conform to IEC 60096-2 or IEC 61196. Where cable designs deviating from these publications are required they shall comply with the requirements of the detail specification. If required, the manufacturer may use additional protective tubing or cable deviating from IEC 61196, in order to
31、 comply with the requirements of the detail specification. The materials used in the cable shall be given as engineering information in the detail specification. 4.2 Connector design and construction Connectors should conform to IEC 61169. Where connector designs deviating from IEC 61169 are require
32、d, the interface should conform to the relevant part of IEC 61169 where available and shall comply with the requirements of the detail specification. The materials used in the connector shall be given as engineering information in the detail specification. 4.3 Outline and interface dimensions The ou
33、tline and interface dimensions shall be in accordance with the detail specification of the cable assembly. The length, unless otherwise specified in the detail specification, is defined as between the reference planes of the connectors. In the case of right-angle connectors, the length applies to th
34、e axis of the connectors (see Figure 1) If not indicated in the detail specification, the length tolerance shall be 1 % for cables equal to, or longer than, 300 mm and 3 mm for cables shorter than 300 mm.
