24、 cable assemblies 1 Scope This part of IEC 60966 is a sectional specification that relates to flexible coaxial cable assemblies operating in the transverse electromagnetic mode (TEM). It establishes uniform requirements for testing the electrical, mechanical and climatic properties of flexible cable
25、 assemblies composed of flexible 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 sectional specification, a cable assembly is always regarded as an integral unit. All specifications apply to the fi
26、nished 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 required by the particular application. This application will not necessarily require all tests. 2 Normative refer

34、ation. 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 with the detail specification of the cable assembly. The length, unless otherwise specifi
35、ed in the detail specification, is defined as between the reference planes of the connectors. In case of right angle connectors the length applies to the 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 lon
36、ger than, 300 mm and 3 mm for cables shorter than 300 mm.
