60966-1 © IEC:1999– 11 –INTERNATIONAL ELECTROTECHNICAL COMMISSION–––––––––––––RADIO FREQUENCY AND COAXIAL CABLE ASSEMBLIES –Part 1: Generic specification – General requirements and test methodsFOREWORD1)The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the International Organizationfor Standardization (ISO) in accordance with conditions determined by agreement between the twoorganizations.2)The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards, 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 InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment 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 subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 60966-1 has been prepared by subcommittee 46A: Coaxial cables,of IEC technical committee 46: Cables, wires, waveguides, r.f. connectors and accessories forcommunication and signalling.This second edition cancels and replaces the first edition published in 1988, amendment 1(1990) and amendment 2 (1995) and constitutes a technical revision.The text of this standard is based on the following documents:FDISReport on voting46A/343/FDIS46A/346/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.Annexes A and E form an integral part of this standard.Annexes B, C and D are for information only.SIST EN 60966-1:2001



60966-1 © IEC:1999– 13 –RADIO FREQUENCY AND COAXIAL CABLE ASSEMBLIES –Part 1: Generic specification – General requirements and test methods1 ScopeThis International Standard specifies requirements for radio frequency coaxial cableassemblies operating in the transverse electromagnetic mode (TEM) and establishes generalrequirements for testing the electrical, mechanical and environmental properties of radiofrequency coaxial cable assemblies composed of cables and connectors. Additionalrequirements relating to specific families of cable assemblies are given in the relevantsectional specifications.NOTE 1 – The design of the cables and connectors used should preferably conform to the applicable parts ofIEC 61196 and IEC 61169 respectively.NOTE 2 – This specification does not include tests which are normally performed on the cables and connectorsseparately. These tests are described in IEC 61196-1 and IEC 61169-1 respectively.NOTE 3 – Wherever possible, cables and connectors used in cable assemblies, even if they are not described inthe IEC 61196 or IEC 61169 series are tested separately according to the tests given in the relevant genericspecification.NOTE 4 – Where additional protection is applied to a cable assembly, the mechanical and environmental testsdescribed in this standard are applicable.2 Normative referencesThe following normative documents contain provisions which, through reference in this text,constitute provisions of this part of IEC 60966. At the time of publication, the editions indicatedwere valid. All normative documents are subject to revision, and parties to agreements basedon this part of IEC 60966 are encouraged to investigate the possibility of applying the mostrecent editions of the normative documents indicated below.
