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 60966-4-3 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.

AVANT-PROPOS

1) La Commission Electrotechnique Internationale (IEC) est une organisation mondiale de normalisation composée

de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l’IEC). L’IEC a pour objet de

favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines de

l'électricité et de l'électronique. À cet effet, l’IEC – entre autres activités – publie des Normes internationales,

des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au public (PAS) et des

Guides (ci-après dénommés "Publication(s) de l’IEC"). Leur élaboration est confiée à des comités d'études, aux

travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les organisations

internationales, gouvernementales et non gouvernementales, en liaison avec l’IEC, participent également aux

travaux. L’IEC collabore étroitement avec l'Organisation Internationale de Normalisation (ISO), selon des

conditions fixées par accord entre les deux organisations.

2) Les décisions ou accords officiels de l’IEC concernant les questions techniques représentent, dans la mesure du

possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l’IEC intéressés

sont représentés dans chaque comité d’études.

3) Les Publications de l’IEC se présentent sous la forme de recommandations internationales et sont agréées

comme telles par les Comités nationaux de l’IEC. Tous les efforts raisonnables sont entrepris afin que l’IEC

s'assure de l'exactitude du contenu technique de ses publications; l’IEC ne peut pas être tenue responsable de

l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.

4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de l’IEC s'engagent, dans toute la

mesure possible, à appliquer de façon transparente les Publications de l’IEC dans leurs publications nationales

et régionales. Toutes divergences entre toutes Publications de l’IEC et toutes publications nationales ou

régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.

5) L’IEC elle-même ne fournit aucune attestation de conformité. Des organismes de certification indépendants

fournissent des services d'évaluation de conformité et, dans certains secteurs, accèdent aux marques de

conformité de l’IEC. L’IEC n'est responsable d'aucun des services effectués par les organismes de certification

indépendants.
