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 60966-3-1 has been prepared by 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
2009-01.
This third edition cancels and replaces the second edition published in 2003 and constitutes a
technical revision.
The major change with respect to the first edition is the reference to the third edition of the
sectional specification.
This blank detail specification is to be read in conjunction with the second edition of
IEC 60966-1 (1999) and with the third edition of IEC 60966-3 (2008).

INTRODUCTION
This part of IEC 60966 is a blank detail specification that relates to semi-flexible coaxial cable
assemblies operating in the transverse electromagnetic mode (TEM).
The creation of a uniform layout and style of a detail specification is determined by the use of
a blank detail specification pro forma. The detail specification may be prepared by the
insertion of data into the pro forma by a national standards organization, by an approved
manufacturer or by a user (when prepared by a user, the detail specification shall be
submitted to the national authorized institution by an approved manufacturer).
Instructions to complete a blank detail specification:
Detail specifications should, as far as possible, be written in accordance with the pro forma
which has:
– a front page with a general description and a drawing or isometric sketch of the cable
assembly and its possible variants;
– ratings, characteristics and inspection requirements (those which are not required or
specified shall be omitted).
Under quality assessment, tests are divided into groups. Whenever possible, entire groups
are either specified or omitted.
These groups are:
Ba (basic) Visual and dimensional tests
Eb (electrical basic) Low-frequency operational tests
Eh (electrical high frequency) High-frequency tests
Ep (electrical phase) Electrical length tests
Ee (electrical screening effectiveness) Screening effectiveness tests
Ez (electrical impedance Z) Impedance uniformity tests
Et (electrical transmission) Power rating test
Mn (mechanical) Mechanical tests
Vc (environmental climatic) Climatic tests
Vv (environmental vibration) Vibration, bumps and shock tests
Vt (environmental temperature) Humidity, rapid change of temperature and
chemical tests
Vf (environmental flammability) Flammability, dust and water immersion tests

[12] The applicable quality assessment test groups according to Table 1 of the sectional
specification (for example, Ba, Eh, Eb).
[13] Description, of the components used for the manufacture of the cable assembly. When
the components do not conform with the relevant publication(s), their relevant materials
requirements shall be listed.
[14] Variants of the cable assembly may be listed in one detail specification. The variants
may differ by colour, connector material, connector sex or type. (Inspection for quality
conformance will be the same for all variants whereas the ratings and characteristics
can change.)
[15] Number of pages of the blank detail specification including the annexes.
[16] Ratings and characteristics of the cable assembly. The properties not specified should
be omitted.
[17] Reference to the appropriate subclause in the sectional and generic specifications.
[18] The value either guaranteed or used for the defined test.
[19] All information required by the sectional specification and any remarks considered as
important for understanding the test.
[20] Test groups (corresponding to box [12] on page 1 of the blank detail specification).
[21] Name of test and its subclause number in the sectional and generic specifications.
[22] Periodicity of the test. The periodic tests apply only in the case of qualification approval.
[23] Inspection level selected from IEC 60410.
