This part of IEC 60966 specifies requirements for radio frequency coaxial cable assemblies operating in the transverse electromagnetic mode (TEM) and establishes general requirements for testing the electrical@ mechanical and environmental properties of radio frequency coaxial cable assemblies composed of cables and connectors. Additional requirements relating to specific families of cable assemblies are given in the relevant sectional specifications. The design of the cables and connectors used will preferably conform to the applicable parts of IEC 61196 and IEC 61169 respectively. NOTE 1 This document does not include tests which are normally performed on the cables and connectors separately. These tests are described in IEC 61196-1 (all parts) and IEC 61169-1 respectively. NOTE 2 Wherever possible@ cables and connectors used in cable assemblies@ even if they are not described in the IEC 61196 or IEC 61169 series@ are tested separately according to the tests given in the relevant generic specification. NOTE 3 Where additional protection is applied to a cable assembly@ the mechanical and environmental tests described in this document are applicable.
