23、EN 50288-5-1:2013 - 4 - 1 Scope EN 50288-5-1 is a sectional specification for screened cables, characterised from 1 MHz up to 250 MHz, to be used in horizontal and building backbone wiring as defined in EN 50173. This sectional specification contains the electrical, mechanical, transmission and envi
24、ronmental performance characteristics of the cables, when tested in accordance with the referenced test methods. This sectional specification is to be read in conjunction with EN 50288-1 that contains the essential provisions for its application. The cables covered in this sectional specification ar
25、e intended to operate with voltages and currents normally encountered in communication systems. These cables are not intended to be used in conjunction with low impedance sources, for example, the electric power supplies of public utility mains. 2 Normative references The following documents, in who
