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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 61169-24 has been prepared by subcommittee 46F: RF and
microwave passive components, of IEC technical committee 46: Cables, wires, waveguides,
R.F. connectors, R.F. and microwave passive components and accessories.
This bilingual version (2014-01) corresponds to the monolingual English version, published in
2009-02.
This second edition cancels and replaces the first edition published in 2001. It constitutes a
technical revision.
This second edition differs from the first edition in that all drawings have been reworked and
improved to allow frequency extension up to 3 GHz.

3.2 Mechanical gauges


Millimetres are original dimensions.


All undimensioned pictorial configurations are for reference purposes only.


3.2.1 Mating socket centre conductor acceptance diameter test


In order to verify that the centre female contact of the socket does not suffer from mechanical

deformation when mated with the full range of indicated inner conductor diameters, a test has
been devised. This test measures the force required to insert and withdraw a selection of
precision test pins into and out of the “F” female socket under test.

NOTE Retention of the inner conductor should be by means of pressure exerted by the conductive centre female
contact, not by means of any other non-conductive insert within the reference plane opening.
The test apparatus should be so
designed as to enable accurate
alignment of the “F” female socket under
test with the precision test pin. The
apparatus should hold either the socket
or the test pin in a fixed position, and the
moving part of the apparatus should be
fitted with an instrument capable of
measuring the insertion and withdrawal
force.
Using the test sequence shown below,
0,2-0,3 × 45°
the insertion and withdrawal force shall
Polish
be measured and recorded in newtons.

The insertion force required to insert the test pin into the socket centre female contact shall
not exceed 20 N under all circumstances.


The withdrawal force required to withdraw the test pin from the socket centre female contact
shall be a minimum of 0,3 N under all circumstances.

3.2.2 Mating port centre conductor acceptance electrical test

After completion of the mechanical tests described in 3.2.1, the centre conductor contact

resistance, when re-mated with a male “F” plug whose centre conductor diameter is

0,635 mm, shall not exceed 10 mΩ with an applied test ampere rate of 1 A.

3.2.3 Reference plane electrical contact
The electrical contact shall be made by the mating of the reference plane face of the “F”
female socket with the mating face of the “F” male plug and not by the threads alone.
