IEC 60966-2-1:2024

Radio frequency and coaxial cable assemblies - Part 2-1: Sectional specification for flexible coaxial cable assemblies

IEC 60966-2-1:2024 is a sectional specification that relates to flexible RF coaxial cable assemblies operating in the transverse electromagnetic mode (TEM). It establishes uniform requirements for testing the electrical, mechanical and climatic properties of flexible cable assemblies composed of flexible RF coaxial cables and RF coaxial connectors.
This part of IEC 60966 applies to flexible cable assemblies composed of flexible RF coaxial cables and coaxial connectors. Flexible RF cable assemblies are widely used in mobile communication systems, microwave test equipment, radar, aerospace and other fields.
NOTE 1 For the purposes of this sectional specification, a cable assembly is always regarded as an integral unit. All specifications apply to the finished assembly and not to individual and non-assembled parts thereof.
NOTE 2 This sectional specification can be supplemented with detail specifications giving additional details as required by the particular application. This application will not necessarily require all tests.

Cordons coaxiaux et cordons pour fréquences radioélectriques – Partie 2-1: Spécification intermédiaire pour cordons coaxiaux souples

L’IEC 60966-2-1:2024 est une spécification intermédiaire qui concerne les cordons coaxiaux RF souples qui fonctionnent en mode électromagnétique transverse (TEM). Elle établit des exigences uniformes pour contrôler les propriétés électriques, mécaniques et climatiques des cordons souples composés de câbles coaxiaux RF souples et de connecteurs coaxiaux RF.
La présente partie de l’IEC 60966 s’applique aux cordons souples composés de câbles coaxiaux RF souples et de connecteurs coaxiaux. Les cordons RF souples sont largement utilisés dans les systèmes de communication mobile, le matériel d’essai hyperfréquences, les radars, l’aérospatial et d’autres domaines.
NOTE 1 Pour les besoins de la présente spécification intermédiaire, un cordon est toujours considéré dans son intégralité. Toutes les spécifications s’appliquent au cordon fini et non à des parties individuelles et non assemblées de celui-ci.
NOTE 2 La présente spécification intermédiaire peut être complétée par des spécifications particulières donnant des détails supplémentaires comme l’exige l’application particulière. Cette application n’exigera pas obligatoirement tous les essais.

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 u
