with polytetrafluoroethylene (PTFE) insulation
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international cooperation on all questions concerning standardization in the electrical and
electronic fields. To this end and in addition to other activities, the IEC publishes International Standards.
Their preparation is entrusted to technical committees; any IEC National Committee interested in
the subject dealt with may participate in this preparatory work. International, governmental and
non-governmental organizations liaising with the IEC also participate in this preparation. The IEC
collaborates closely with the International Organization for Standardization (ISO) in accordance with
conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of the IEC on technical matters, prepared by technical committees on
which all the National Committees having a special interest therein are represented, express, as nearly as
possible, an international consensus of opinion on the subjects dealt with.
3) They have
the form of recommendations for international use published in the form of standards, technical
reports or guides and they are accepted by the National Committees in that sense.
4)
In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5)
The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
International Standard IEC 1196-2 has been prepared by sub-committee 46A: Coaxial
cables, of IEC technical committee 46: Cables, wires, waveguides, r.f. connectors and
accessories for communication and signalling.
This second edition cancels and replaces the first edition published in 1993 of which it
constitutes a minor revision.
IEC 1196-2 constitutes pa rt 2 of a series of publications under the general title: Radio-
frequency cables.
Annex A is for information only.

RADIO-FREQUENCY CABLES -
Part 2: Sectional specification for semi-rigid
radio-frequency and coaxial cables
with polytetrafluoroethylene (PTFE) insulation
Section 1: General
1.1 Scope and object
This sectional specification specifies requirements for semi-rigid radio frequency and
coaxial cables with polytetrafluoroethylene (PTFE) insulation.
It is intended to be used with the generic specification (IEC 1196-1).
The object of this sectional specification is to prescribe recommended ratings and
characteristics and to select from the generic specification the appropriate quality
rformance
assessment procedures, test and measuring methods, and to give general pe
requirements for semi-rigid coaxial cables plus complementary test methods. Test
severities and requirements prescribed in detail specifications referring to this sectional
specification should be of equal or higher performance levels.
1.2 Normative references
The following normative documents contain provisions which, through reference in this
text, constitute provisions of this sectional specification. At the time of publication, the
editions indicated were valid. All normative documents are subject to revision, and parties
to agreements based on this sectional specification are encouraged to investigate the
possibility of applying the most recent editions of the normative documents indicated
below. Members of IEC and ISO maintain registers of currently valid International
Standards.
IEC 28: 1925, International Standard of resistance for copper

IEC 1196-1: 1995, Radio-frequency cables - Part 1: Generic specification: General,
definitions, requirements and test methods
1.3 Definitions
For the definitions of general terms used in this specification, reference should be made to
the generic specification.
---------------------- Page: 8 ----------------------
1196-2 ©IEC:1995 - 9 -
1.4 Information to be given in a detail specification
Detail specifications shall not specify requirements inferior to those in the generic or
sectional specification. When more severe requirements are included, they shall be listed
in the detail specification and indicated in the test schedules.
Information covered in 1.4.1 to 1.4.4 shall be included in the detail specification and the
value quoted shall be selected from the preferred values given in this sectional
specification. Examples of detail specifications are given in annex A.
1.4.1 Outline drawing and dimensions
There shall be an illustration of the cable as an aid to easy recognition and for comparison
of the cable to others. As a minimum requirement, the diameter of the dielectric and the
outer diameter of the cable shall be specified. All dimensions and their tolerances which
affect interchangeability and termination shall be given in millimetres and tabulated below
the drawing.
1.4.2 Materials
The detail specification shall specify the materials of both the inner and outer conductors.
The insulation shall be of solid polytetrafluoroethylene having a thickness as specified in
the detail specification.
1.4.3 Ratings and characteristics
The ratings and characteristics shall be in accordance with the relevant clauses of this
specification.
1.4.4 Marking of package
The package containing the cable shall be clearly marked with the manufacturer's name
and the cable IEC type designation.
Section 2: Ratings and characteristics
The values given in the detail specification shall be selected from the following
recommended requirements.
2.1 Climatic category
Due to the particular structure of semi-rigid coaxial cables and the associated differential
thermal expansion coefficients of materials, rated temperatures are specific for each cable
and shall be given in the detail specification.
---------------------- Page: 9 ----------------------
1196-2 ©IEC:1995 - 11 -
The operating temperature range is between the limits within which a cable may be
operated continuously without any reduction in the basic properties of the cable. This
includes the ambient temperature plus the increased temperature due to cable operation.
The temperature range is given as a guideline, since the mechanical, environmental and
electrical requirements of the application can affect the operating temperature range. In no
case shall the testing temperatures be considered as giving the operating temperature
range. Testing is usually carried out under accelerated conditions in an attempt to reveal
any faults in the materials used in the construction of the cable assembly.
The maximum power-handling capability, in watts, is the amount of power that a coaxial
cable can safely transmit without overheating or developing a dielectric breakdown
throughout the usable frequency range. The safe power-handling capabilities are shown
on the associated curves. These curves have been derated with an assumption of a
VSWR of 2 and an ambient temperature of 25 °C. The curves have also taken into account
the effects of a typical system installation, for example bends, clamps and thermally insu-
lated sections.
2.2 Recommended ratings
2.2.1 Characteristic impedance
Preferred values are 50 S2 or 75 S2.
2.2.2 Tolerance on characteristic impedance
Tolerances on rated characteristic impedances shall be selected from the following values:
±0,5 S2, ±1 S2, ±1,5 S2, ±2 S2
2.2.3 Rated temperature
The standard value of rated temperature is 20 °C.
Section 3: Additional requirements
3.1 Design and construction of outer conductor
The outer conductor shall be a smooth and continuous metallic tube, either of copper or
light metal alloy.
Copper
The type used shall be annealed, electrolytically refined with a copper content of at least
99,9 % and an electrical conductivity of at least 100 % according to IEC 28.
---------------------- Page: 10 ----------------------
1196-2 ©IEC:1995 - 13 -
The mechanical characteristics of the copper tube shall comply with a flattening and
bending test which is carried out on a section of tube. The tube shall be completely
flattened and then folded back on itself. After this test the tube shall not exhibit splits,
cracks, fissures or tears.
Light metal alloy
Under consideration.
3.2 Tests and measurements
3.2.1 Dimensions
3.2.1.1 Eccentricity of dielectric
The eccentricity of the dielectric shall be measured in accordance with the method
specified in 9.2 of the generic specification.
