FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). 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. 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 IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not notice of (a) patent(s), which may be
required to implement this document. However, implementers are cautioned that this may not represent the latest
information, which may be obtained from the patent database available at https://patents.iec.ch and
www.iso.org/patents . IEC shall not be held responsible for identifying any or all such patent rights.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition IEC 61196-1-102:2005. A vertical bar appears in the margin
wherever a change has been made. Additions are in green text, deletions are in
strikethrough red text.
IEC 61196-1-102 has been prepared by subcommittee 46A: Coaxial cables, of IEC technical
committee 46: Cables, wires, waveguides, RF connectors, RF and microwave passive
components and accessories. It is an International Standard.
This second edition cancels and replaces the first edition, published in 2005. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) the scope was extended;
b) the procedure is updated for the period of discharge and the test sample with high insulation
resistance;
c) the unit of cable length has been amended;
d) the test procedures for the cables with special structure are specified in Annex A.
The text of this International Standard is based on the following documents:

1 Scope
This part of IEC 61196 applies to coaxial communication cables. It specifies test methods for
determining the insulation resistance of coaxial cables. It is intended to detect the flaws in the
dielectric of finished coaxial cables.
The test procedures for the cables with special structure are specified in Annex A accordingly.

4 Test for insulation resistance of dielectric
4.1 Principle
The purpose of the test is to determine the DC insulation resistance of the insulation material
between the inner conductor and the outer conductor or screen or the DC insulation resistance
of an insulating material between the outer conductor and additional screens or metallic
elements of a cable.
4.2 Test equipment
– DC power supply > 80 V DC and ≤ 500 V DC, unless otherwise specified.
– Megohmmeter with a range ≥ 2‧10 MΩ.
4.3 Preparation of the test specimen
The test shall be carried out on a delivery length of finished cable after preconditioning at a
temperature between 15 °C and 35 °C and checking the continuity of the conductors. The
conductor ends shall be stripped of insulation.
4.4 Procedure
Unless otherwise specified, the insulation resistance shall be measured between inner and
outer conductor and/or between outer conductor and additional screens or metallic elements. If
it is not specified in the relevant cable specification, the test voltage shall be 500 V and the
minimum period of electrification shall be 1 min while the minimum period of discharge shall be
3 min.
If the test sample with high insulation resistance, notably, for the insulation resistance is greater
than 1‧10 MΩ, the test result can be affected by the electromagnetic fields. In this case, the
test sample shall be stored in a metal box that is fixed to the ground.
4.5 Expression of results
The insulation resistance shall be expressed in MΩ∙km. When the test length differs from 1 000
m, the measured value shall be corrected as follows:
𝑙𝑙
(1)
𝑅𝑅 =𝑅𝑅 .
m
1 000
where
R is the corrected insulation resistance in MΩ∙km;
Rm is the insulation resistance measured, in MΩ;
l is the cable length, in km m.
5 Test report
The test report shall give the following test conditions and record the measured and the
corrected value of the insulation resistance in MΩ∙km:
– temperature, in °C;
– CUT length, in m;
– test voltage, in V.
6 Requirement
The corrected value of the insulation resistance shall comply with that indicated in the relevant
sectional or detail specification.
