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 60966-3-3 has been prepared by IEC technical committee 46: Cables, wires, waveguides,
RF connectors, RF and microwave passive components and accessories. It is an International
Standard.
It has the status of a horizontal standard in accordance with IEC Guide 108.
The text of this International Standard is based on the following documents:

RADIO FREQUENCY AND COAXIAL CABLE ASSEMBLIES –
Part 3-3: Detail specification for semi-flexible cable assemblies (Jumper) –
Frequency range up to 18 GHz, Type 50‑141 semi-flexible coaxial cable
1 Scope
This part of IEC 60966 is a detail specification that relates to semi-flexible cable assemblies
composed of type 50-141 semi-flexible coaxial cables with polytetrafluoroethylene (PTFE)
dielectric (IEC 61196-8-4) and connectors such as, type SMA (IEC 61169-15), type N
(IEC 61169-16). It gives subfamily detail requirements and severities to be applied.
These cable assemblies are mainly used in the field of microwave and wireless equipment or
other signal transmission equipment or units. The operating frequency is up to 18 000 MHz.
The qualification will be conducted in accordance with IEC 60966-3. Once one variant obtains
the qualification approval, the other variant with the same cable and connection type can obtain
the qualification approval by conducting tests whose results might depend on the variants.
Under capability approval, the qualification will be conducted on the relating CQCs (capability
qualifying components) as defined in IEC 60966-3 and described in the CM (capability manual).
Unless otherwise specified in the CM, only lot-by-lot tests from groups Ba and Eb will be
conducted on delivered products, all other tests will be performed on CQCs as defined in
IEC 60966-3 and described in the CM.
