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.
IEC 61169-17 has been prepared by subcommittee 46F: RF and microwave passive
components, of IEC technical committee 46: Cables, wires, waveguides, RF connectors, RF
and microwave passive components and accessories. It is an International Standard.

5 Quality assessment procedures
5.1 General
Subclauses 5.2 to 5.3 provide recommended ratings, performance and test conditions to be
considered when writing a detail specification (DS). 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.
5.2 Ratings and characteristics
Preferred climatic categories are given in Table 7.
The values indicated below are recommended for TNC 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. Ratings and characteristics are given in Table 8.

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.

6 Instructions for preparation of detail specifications (DS)
6.1 General
Detail specifications (DS) writers shall use the appropriate blank detail specification (BDS).
The following pages comprise the pro-forma BDS dedicated for use with series TNC connectors.
As such, it will have already entered on it information in relation to:
a) the basic specification number applicable to all the detail specifications covering connector
styles of the series covered by the sectional specification;
b) the connector series designation.
The specification writer should enter the details relating to the connector style to be covered as
indicated. The numbers in brackets in the BDS correspond to the following indications, which
shall be given.
6.2 Identification of the component
(1) Enter the following details:
– Style: the style designation of the connector including type of fixing and sealing if
applicable.
– Attachment: by deletion of the inapplicable options of cable/wire given for centre and
outer conductors.
– Special features and marking: as applicable.
– Series designation: in bold characters/digits approximately 15 mm high.
(2) Enter detail of assessment level and the climatic category.
(3) A reproduction of the outline drawing and details of the panel piercing (if applicable). It shall
provide the maximum envelope dimensions, also the position of the reference plane, and,
in the case of a fixed connector, the position of the mounting plane(s), relative to the front
face of the connector
(4) Any maximum panel thickness limitation for fixed connectors shall be stated.

(5) Particulars of all variants covered by the DS. As appropriate, the information shall include:
– cable series (or sizes) applicable to each variant;
– alternative plated or protective finishes;
– details of alternative mounting flanges having either tapped or plain mounting holes;
– details of alternative solder spills or solder buckets including, when applicable those for
use with microwave integrated circuit (MIC) components.
6.3 Performance
(6) Performance data listing the most important characteristics of the connectors in accordance
with the requirements of the relevant sectional specification. Deviations from the minimum
requirements shall be clearly indicated. Non applicable parameters shall be marked "na".
6.4 Marking, ordering information and related matters
(7) Insert marking and ordering information as appropriate, together with details of related
documents and any invoked structural similarity.
6.5 Selection of tests, test conditions and severities
(8) "na" shall be used to indicate non-applicable test. All tests marked "a" by the detail
specification writer shall be mandatory.
When using the normal procedure with a dedicated BDS, the letter "a" − for applicable − shall
be entered in the "test required" column against each of the tests indicated as being mandatory
in the test schedule of the relevant sectional specification. Any additional test required at the
discretion of the specification writer shall also be indicated by an "a".
The specification writer shall also indicate, when necessary, details of deviations from the
standard test conditions, including any relevant deviations given in the test schedule of the
sectional specification.
