22、 the transverse electromagnetic mode (TEM). It establishes 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 generi
23、c specification. NOTE 2 For the purpose of this sectional 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 d
24、etail specifications giving additional details as required 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.

Whe
28、re 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 comply with the requirements of the detail specificat
29、ion. 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 required, the interface should conform to the relevant part o

The materials used in the connector shall be given as engineering information in the detail specification. 4.3 Outline and interface dimensions The outline and interface dimensions shall be in accordance
31、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 the axis of the connectors (see Figure 1) If not indicat
32、ed 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.
