13、3 on 2009-04-01. This European Standard supersedes EN 60966-3:2003. The major change with respect to EN 60966-3:2003 is a better definition of the tests to be performed. This sectional specification is to be read in conjunction with EN 60966-1:1999. It contains the same clauses as that of EN 60966-1
14、 and completes or amends them when required. When a clause of EN 60966-1 does not appear in this standard, it applies as it is in EN 60966-1. When this standard states “addition“, “modification“ or “replacement“, the relevant text in Part 1 is to be adapted accordingly. The following dates were fixe

24、E ASSEMBLIES Part 3: Sectional specification for semi-flexible coaxial cable assemblies 1 Scope This part of IEC 60966 is a sectional specification that relates to semi-flexible coaxial cable assemblies operating in the transverse electromagnetic mode (TEM). It establishes uniform requirements for t
25、esting the electrical, mechanical and climatic properties of flexible cable assemblies composed of flexible coaxial cables and coaxial connectors. NOTE 1 For the purposes of this sectional specification, a cable assembly is always regarded as an integral unit. All specifications apply to the finishe
26、d assembly and not to individual and non-assembled parts thereof. NOTE 2 This sectional specification should be supplemented with detail specifications giving additional details as required by the particular application. This application will not necessarily require all tests. 2 Normative references
