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.

5.4 Procedures for quality conformance
5.4.1 Quality conformance inspection
This shall consist of test group A1 and B1 on a lot-by-lot basis.
5.4.2 Qualification approval and its maintenance
5.4.2.1 General procedure
This shall consist of three consecutive lots passing test groups A1 and B1 followed by selection
of specimens from the lots as appropriate. These specimens shall successfully pass the
specified periodic group D tests.
5.4.2.2 Procedure for quality conformance involving structural similarity
During the initial procedure, the declared structurally similar styles and variants may be included
by merely subjecting the distinguishing piece-part(s) to subgroup D3 testing.
When structurally similar styles or variants are to be added to an existing conformance
document, they shall be assembled and subject to group A1 and group B1 testing and any
appropriate group D tests. The distinguishing piece-parts shall be subjected to subgroup D3
testing before inclusion of the additional style or variant on the conformance document.
It should be noted that:
a) connector styles and variants of styles may be qualified by invoking structural similarity
when applicable;
b) it may not always be considered necessary to assemble and test all structurally similar styles
and variants as complete connectors.
5.5 Test and measurement procedures
5.5.1 General
The related clauses cover the majority of tests and measuring procedures required for the
qualification approval and conformance inspection of RF connectors. However,
• not all the tests are applicable to all sectional and detail specifications;
• the sectional specification shall specify the tests (and any additional tests) applicable to a
particular connector type;
• detail specifications shall identify which of the non-mandatory tests specified in the relevant
sectional specification are applicable to a particular style/variant of connector;
• any additional test methods shall be clearly identified as such.
5.5.2 Schedule of basic test groupings for acceptance and periodic tests
5.5.2.1 General
Unless otherwise specified in the sectional specification (SS), the schedule below shall provide
the basis for qualification approval and quality conformance inspection tests to be included in
each SS.
Details of any deviations necessary from the standard test method and/or conditions are to be
indicated. Tests are to be carried out in the order shown unless otherwise specified.

5.5.2.2 Sampling and lot-by-lot system
One of the following procedures is to be used.
a) Fixed quantity sample procedure
This shall consist of the appropriate fixed quantity sample passing test groups A1 and B1
followed by selection of specimens from the lots as appropriate. These specimens shall
successfully pass the specified periodic D tests.
b) Lot-by-lot
This shall consist of three consecutive lots passing test groups A1 and B1 followed by the
selection of specimens from the lots as appropriate. These specimens shall successfully
pass the specified periodic group D tests.
6 Specifications
6.1 Specification structures
The relationship between the generic, general blank detail, sectional and detail specifications
is detailed hereafter.
6.1.1 Sectional specification (SS)
Each sectional specification relates only to a particular series or type of RF connector, e.g. type
SMA, type N, type BNC, etc.
It specifies:
• mating face dimensions for general purpose and for test connectors;
• gauging information – particularly that applicable to resilient contacts;
• performance parameters common to all connector styles within the series;
• mandatory tests, indicated by "a" for applicable in the test schedule, and levels of
conformance inspection for two levels of quality assessment to be observed when writing
an associated detail specification.
The SS also provides recommended ratings, performance characteristics and test conditions to
be considered when writing a DS together with any general deviations from the test conditions.
6.1.2 Detail specification (DS)
Detail specifications for levels M and H shall normally be prepared using the blank detail
specification provided in 6.1.4 and periodicity of certain specialized tests is dependent upon the
physical and electrical characteristics of the individual connector style/variant(s) covered by the
DS.
The detail specification, when completed, shall provide the user, manufacturer, test house and
certification body with all the necessary information for the approval testing and quality
conformance inspection relating to a connector style and any variants within a specific series
of RF connectors.
6.1.3 Blank detail specification (BDS)
6.1.3.1 General
Detail specifications (DS) writers shall use the appropriate blank detail specification (BDS).

– 24 – IEC 61169-66:2021 © IEC 2021
The following pages comprise the pro forma BDS dedicated for use with 50 Ω type 2,2-5
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.
6.1.3.2 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 details 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 limitations for fixed connectors shall be stated.
5) Particulars of all variants covered by the DS. As appropriate, the information shall include:
– cable types (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.
6.1.3.3 Performance
6) Performance data listing the most important characteristics of the connector in accordance
with the requirements of the relevant sectional specification. Deviations from the minimum
requirements shall be clearly indicated. Non applicable shall be marked “na”.
6.1.3.4 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.
6.1.3.5 Selection of tests, test conditions and severities
8) “na” shall be used to indicate non-applicable tests. 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 tests
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.
