IEC 62037-4:2012

Passive RF and microwave devices, intermodulation level measurement - Part 4: Measurement of passive intermodulation in coaxial cables

IEC 62037-4:2012 is part of the IEC 62037 series, and defines test fixtures and procedures recommended for measuring levels of passive intermodulation generated by coaxial cables. Two dynamic test methods and a static test method are defined.

Dispositifs RF et à micro-ondes passifs, mesure du niveau d'intermodulation - Partie 4: Mesure de l'intermodulation passive dans les câbles coaxiaux

La CEI 62037-4:2012 définit les dispositifs et les procédures d'essai recommandés pour mesurer les niveaux d'intermodulation passive générés par les câbles coaxiaux. Deux méthodes d'essais dynamiques et une méthode d'essai statique sont définies. Tous les câbles coaxiaux sont soumis à l'essai statique et à l'essai dynamique d'une boucle de câble fixée. Les câbles classés comme souples ou semi-souples sont en plus soumis à l'essai dynamique avec outil de flexion.

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.
International Standard IEC 62037-4 has been prepared by technical committee 46: Cables,
wires, waveguides, R.F. connectors, R.F. and microwave passive components and
accessories.
The text of this standard is based on the following documents:
FDIS Report on voting

Part 4: Measurement of passive intermodulation in coaxial cables

1 Scope
This part of IEC 62037 defines test fixtures and procedures recommended for measuring
levels of passive intermodulation generated by coaxial cables. Two dynamic test methods and
a static test method are defined.
All coaxial cables are subjected to the static and clamped cable loop dynamic test.
Cables classified as flexible or semi-flexible are additionally subjected to the flexing tool
dynamic test.
