52 Part 3: Sectional specification for semi-flexible coaxial cable assemblies
53
54 1 Scope
55 This part of IEC 60966 is a sectional specification that relates to semi-flexible coaxial cable
56 assemblies operating in the transverse electromagnetic mode (TEM). It specifies the design
57 and construction, IEC type designation, workmanship, marking and packaging, standard rating
58 and characteristics, electrical, mechanical and environmental requirements of finished semi-
59 flexible cable assemblies, quality assessment, delivery and storage, etc.
60 This part of IEC 60966 applies to semi-flexible cable assemblies composed of semi-flexible
61 coaxial cables and coaxial connectors. Semi-flexible cable assemblies are widely used in
62 mobile communication systems, microwave test equipment, radar, aerospace and other fields.
63 NOTE 1： For the purpose of this sectional specification, a cable assembly is always regarded as an integral unit.
64 All specifications apply to the finished assembly and not to individual and non-assembled parts thereof.
65 NOTE 2： This sectional specification should be supplemented with detail specifications giving additional details as
66 required by the particular application. This application will not necessarily require all tests.
67 2 Normative references

83 4 Design and construction
84 4.1 Cable design and construction
85 Cables should conform to IEC 61196-8. Where cable designs deviating from these
86 publications are required, they shall comply with the requirements of the detail specification of
87 the cable.
88 If required, the manufacturer may use additional protective tubing or cable deviating from IEC
89 61196-8, in order to comply with the requirements of the detail specification.
90 The materials used in the cable shall be given as engineering information the relevant detail
91 specification.
92 According to local regulation, raw material of the cable as well as those of additional
93 protection shall be chosen to comply with regional or national Directives and Regulations such
94 as RoHS and REACH in Europe.
95 4.2 Connector design and construction
96 Connectors should conform to IEC 61169. Where connector designs deviating from IEC 61169
97 are required, the interface should conform to the relevant part of IEC 61169 where available
98 and shall comply with the requirements of the detail specification.
99 The materials used in the connector shall be given as engineering information the relevant
100 detail specification.
101 According to local regulation, raw material of the connector as well as those of additional
102 protection shall be chosen to comply with RoHS and other environmental regulation such as
103 REACH in Europe.
104 4.3 The relative position dimensions of the interface
105 The relative position dimensions of the interface of end connector(s) of the cable assemblies
106 should comply with the interface of the relevant part of IEC 61169 or the relevant detail
107 specification. The relative position dimensions of the interface of end connector(s) include the
108 dimension of inner conductor relative to dielectric and inner conductor relative to out
109 conductor.
110 The relative position dimensions of the interface of some typical connectors are shown in
111 Annex A.
112 4.4 Outline of the cable assembly
113 The outline shall be in accordance with the detail specification of the cable assembly.
114 The length, unless otherwise specified in the relevant detail specification, is defined as
115 between the end planes of the connectors. In the case of right-angle connectors, the length
116 applies to the axis of the connectors (see figure 1 and figure2).
117 Unless specified in the relevant detail specification, the length tolerance shall be ±1 % for
118 cables equal to or longer than 300 mm, and±3 mm for cables shorter than 300 mm.
