It is identical with
3、 IEC61196-3:1998. The UK participation in its preparation was entrusted by Technical Committee EPL/46, Cables, wires and waveguides, r.f. connectors, and accessories for communication and signalling, to Subcommittee EPL/46/1, Communication cables, which has the responsibility to: aid enquirers to un
4、derstand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented
5、on this subcommittee can be obtained on request to its secretary. From1 January1997, all IEC publications have the number60000 added to the old number. For instance, IEC27-1 has been renumbered as IEC60027-1. For a period of time during the change over from one numbering system to the other, publica
6、tions may contain identifiers from both systems. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which impleme

A British Standard does not purport to include all the nec
8、essary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pagesi andii, theEN

The object of this sectional specification is to prescribe recommended ratings and characteristics and to select from the generic specification the appropriate quality assessment procedures, test and measuring methods, and to give general performance requirements for coaxial cables for local area
28、 networks plus complementary test methods. Test severities and requirements prescribed in detail specifications referring to this sectional specification should be of equal or higher performance levels. When the requirements of IEC61196-1 and of this sectional specification conflict with each other,
29、 this sectional specification shall prevail. 1.2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC61196.
