Part 1-114: Electrical test methods –
Test for inductance
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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61196-1-114 has been prepared by subcommittee 46A: Coaxial
cables, of IEC technical committee 46: Cables, wires, waveguides, R.F. connectors, R.F. and
microwave passive components and accessories.
The text of this standard is based on the following documents:
FDIS Report on voting
46A/1265/FDIS 46A/1274/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

– 4 – IEC 61196-1-114:2015 © IEC 2015
This standard is intended to be read in conjunction with IEC 61196-1. It is based on the second
edition (2005) of that standard.
A list of all the parts in the IEC 61196 series published under the general title Coaxial
communication cables can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until the
stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data related to
the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
COAXIAL COMMUNICATION CABLES –

Part 1-114: Electrical test methods –
Test for inductance
1 Scope
This part of IEC 61196 details the test methods to determine the inductance characteristics of
coaxial cables used in analogue and digital communication systems.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments)
applies.
IEC 61196-1, Coaxial communication cables – Part 1: Generic specification – General,
definitions and requirements
IEC 61196-1-101, Coaxial communication cables – Part 1-101: Electrical test methods – Test
for conductor d.c. resistance of cable
3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 61196-1 as well as
the following apply.
3.1
inductance
effective inductance (L) of the cable as the sum of the inductances of the inner conductor, the
outer conductor and the mutual inductance between the two conductors
Note 1 to entry: At any (low) frequency, the impedance of a cable can be represented by two components –
resistance (R) and reactance (X) – or as a polar function having magnitude (Z) and phase (θ). The impedance shall
be represented by a series circuit:
R = Z · cos (θ)
and
X = Z · sin (θ)
where
2 2
Z = √(R + X );
tan (θ) = X/R;
X = 2π·f·L.
Note 2 to entry: Inductances normally are measured at low frequencies (f) (50 Hz, 800 Hz or 1 000 Hz) as required
in the relevant cable specification. For this case, the DC resistance (R) shall be measured as de
