FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national
electrotechnical committees (IEC National Committees). The object of the 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, the IEC
publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form of standards,
technical specifications, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards
transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard
and the corresponding national or regional standard shall be clearly indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared
to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights.
The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61156-7-1 has been prepared by subcommittee 46C: Wires and
symmetric cables, of IEC 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

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (CEI) est une organisation mondiale de normalisation composée de
l'ensemble des comités électrotechniques nationaux (Comités nationaux de la CEI). La CEI a pour objet de favoriser
la coopération internationale pour toutes les questions de normalisation dans les domaines de l'électricité et de
l'électronique. A cet effet, la CEI – 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 la CEI"). 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 la CEI, participent également aux travaux. La CEI 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 la CEI concernant les questions techniques représentent, dans la mesure du
possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de la CEI intéressés
sont représentés dans chaque comité d’études.
3) Les Publications de la CEI se présentent sous la forme de recommandations internationales et sont agréées comme
telles par les Comités nationaux de la CEI. Tous les efforts raisonnables sont entrepris afin que la CEI s'assure de
l'exactitude du contenu technique de ses publications; la CEI 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 la CEI s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de la CEI dans leurs publications nationales et
régionales. Toutes divergences entre toutes Publications de la CEI et toutes publications nationales ou régionales
correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) La CEI n’a prévu aucune procédure de marquage valant indication d’approbation et n'engage pas sa responsabilité
pour les équipements déclarés conformes à une de ses Publications.
6) Tous les utilisateurs doivent s'assurer qu'ils sont en possession de la dernière édition de cette publication.
7) Aucune responsabilité ne doit être imputée à la CEI, à ses administrateurs, employés, auxiliaires ou mandataires, y
compris ses experts particuliers et les membres de ses comités d'études et des Comités nationaux de la CEI, pour
tout préjudice causé en cas de dommages corporels et matériels, ou de tout autre dommage de quelque nature que
ce soit, directe ou indirecte, ou pour supporter les coûts (y compris les frais de justice) et les dépenses découlant de
la publication ou de l'utilisation de cette Publication de la CEI ou de toute autre Publication de la CEI, ou au crédit qui
lui est accordé.
8) L'attention est attirée sur les références normatives citées dans cette publication. L'utilisation de publications
référencées est obligatoire pour une application correcte de la présente publication.
9) L’attention est attirée sur le fait que certains des éléments de la présente Publication de la CEI peuvent faire l’objet
de droits de propriété intellectuelle ou de droits analogues. La CEI ne saurait être tenue pour responsable de ne pas
avoir identifié de tels droits de propriété et de ne pas avoir signalé leur existence.
La Norme internationale CEI 61156-7-1 a été établie par le sous-comité 46C: Câbles symétriques
et fils, du comité d'études 46 de la CEI: Câbles, fils, guides d’ondes, connecteurs, composants
passifs pour micro-onde et accessoires.
La présente version bilingue, publiée en 2003-11, correspond à la version anglaise et à son
Corrigendum 1 (2003-09).
Le texte anglais de cette norme est issu des documents 46C/574/FDIS et 46C/592/RVD.
