EN IEC 60966-1 pdf download.RADIO FREQUENCY AND COAXIAL CABLE ASSEMBLIES – Part 1 : Generic specification – General requirements and test methods
1 Scope
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 61 1 96 and IEC 61 1 69 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 61 1 96-1 (all parts) and IEC 61 1 69-1 respectively. NOTE 2 Wherever possible, cables and connectors used in cable assemblies, even if they are not described in the IEC 61 1 96 or IEC 61 1 69 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.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: • IEC Electropedia: available at http://www.electropedia.org/ • ISO Online browsing platform: available at http://www.iso.org/obp 3.1 cable assembly combination of cable(s) and connector(s) with or without any additional protection and with specified performance, used as a single unit 3.2 flexible cable assembly cable assembly where the cable is capable of repeated flexure Note 1 to entry: The cable usually has a braid outer conductor. 3.3 semi-flexible cable assembly cable assembly not intended for applications requiring repeated flexure of the cable in service, but bending or forming is permissible to facilitate installation 3.4 semi-rigid cable assembly cable assembly not intended to be bent or flexed after manufacture Note 1 to entry: Any bending or flexing during installation or use may degrade the performance of the cable assembly. 3.5 insertion loss loss introduced by inserting a cable assembly into a system Note 1 to entry: In this standard, it is the ratio, expressed in decibels, of the power (P 1 ) delivered to a load connected directly to a source and the power (P 2 ) delivered to a load when the cable assembly is inserted between the source and the load.3.6 reflection factor ratio of the complex wave amplitude of the reflected wave to the complex wave amplitude of the incident wave at a port or transverse cross-section of a transmission line 3.7 electrical length equivalent free-space length of the cable assembly 3.8 electrical length difference difference in electrical length between cable assemblies 3.9 phase difference difference in phase between a transverse electromagnetic mode (TEM) wave which has traversed the cable assembly and an identical wave which has traversed another cable assembly 3.1 0 propagation time time taken for the propagation of a TEM wave between the reference planes of the two connectors 3.1 1 minimum static bending radius radius used in climatic tests Note 1 to entry: It is the minimum permissible radius for fixed installation of the cable. 3.1 2 dynamic bending radius radius used for the insertion loss stability, stability of electrical length and flexing endurance testsNote 1 to entry: It is the minimum bending radius for applications where the cable assembly is flexed. Larger bending radii will allow the increase of the maximum number of flexures. 3.1 3 transfer impedance quotient of the induced voltage on the inside of the cable assembly and the inducing current outside the assembly Note 1 to entry: In practice, this is between defined points on connectors mated to the connectors of the cable assembly 3.1 4 screening attenuation ratio of the signal power inside the cable assembly to the total power that radiates outside the cable assembly 3.1 5 power rating input power which may be handled continuously by the cable assembly when terminated by its characteristic impedance Note 1 to entry: For practical application, the maximum power that may be handled is dependent upon the return loss. Note 2 to entry: Power rating is dependent on mounting details, ambient temperature, air pressure and circulation. It is normally specified at an ambient temperature of 40 °C.
