BS EN 50117-9-2 This part of EN 50117 which is a sectional specification applies to coaxial indoor drop cables for analogue and digital one and two way signal transmission, e.g. for cable networks for television signals, sound signals and interactive services in accordance with EN 60728-1, EN 60728-1-1, EN 60728-101, EN 60728-10, EN 50173-1 and EN 50173-4. This includes also the transmission of BCT signals provided by a CATV, MATV or SMATV cable network. The purpose of this document is to specify the applicable test methods and requirements for the electrical, mechanical and environmental characteristics and for fire performance of the cables.when submitted to the maximum current under nominal ambient conditions does not affect the mechanical and electrical properties of the cable. Cables according to this standard may be operated at voltages > 50 V AC or >75 V DC according to the detail specification of the manufacturer. However, these cables are not intended for direct connection to the mains electricity supply or other low impedance sources. Cables according to this standard shall be designed according to EN 50290-2-1, Communication cables Part 2-1: Common design rules and construction. They shall be used according to EN 50290-4-1, Communication cables – Part 4-1: General considerations for the use of cables -Environmental conditions and safety aspects. The use of cables according to this standard including delivery, storage and installation shall be in accordance with EN 50290-4 2, Communication cables – Part 4-2: General considerations for the use of cables – Guide to use, unless otherwise specified. Cables according to this standard shall be tested for voltage withstanding. The test is performed between conductors and between the conductors or screen and the outer surface of the sheath. When constructed in accordance with EN 50290-2-1 and EN 50117-1 and submitted to spark testing, CATV cables according to this standard may be installed together with Low Voltage cables. AII cables covered by this standard do not fall under the scope of the RED or the EMC directive. Nevertheless, transfer impedance and screening attenuation according to 5.1.3.6 and 5.1.3.7 shall be specified in the relevant detail specification, if the intended application of the cable is the use in combination with equipment under the RED or the EMC Directive.
