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.
A PAS is a technical specification not fulfilling the requirements for a standard, but made
available to the public.
IEC-PAS 61169-18 has been processed 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.
The text of this PAS is based on the This PAS was approved for
following document: publication by the P-members of the
committee concerned as indicated in
the following document
Draft PAS Report on voting
46F/94/PAS 46F/109/RVD
Following publication of this PAS, which is a pre-standard publication, the technical committee
or subcommittee concerned may transform it into an International Standard.
This PAS shall remain valid for an initial maximum period of 3 years starting from the
publication date. The validity may be extended for a single 3-year period, following which it
shall be revised to become another type of normative document, or shall be withdrawn.

3.2.2 Test procedure
The gauge A shall be inserted into the socket-centre contact three times with a minimum
depth of 1,25 mm (0,049 in). This is a sizing operation and should only be carried out when
the socket-centre contact is removed from the connector.
After this, the gauge B shall have a withdrawal force of 0,25 N minimum after inserted into
socket-centre contact. The contact shall retain the mass of the gauge in a vertical downward
position. This test also shall be carried out on connector when the socket-centre contact is not
removed.

4 Quality assessment procedures
4.1 General
The following subclauses provide recommended rating, performance and test conditions to be
considered when writing a detail specification. They also provide an appropriate schedule of
tests with minimum levels of conformance inspection sampling, together with the pro forma
blank detail specification (BDS) and instructions for the preparation of a detail specification.
4.2 Rating and characteristics (see Clause 6 of IEC 61169-1)
The values indicated below are recommended for SSMA series RF connectors and are given
for the writer of the detail specification. They are applicable for the condition when the
connectors are fully mated.
Certain tests are listed without any recommended values being given. These tests will usually
not be required. When these tests are required, appropriate values shall be entered in the
detail specification at the discretion of the specification writer.
