BS EN 50529-2:2010 5 EN 50529-2:2010 1 Scope This EMC standard specifies requirements for emissions originating from within wire-line telecommunication networks using coaxial cables and the immunity of those networks, including their in-premises extensions by references to harmonised EMC produc
20、t standards and other standards with EMC requirements in combination with good engineering practice, when installed and operated as intended. This standard covers the frequency range 9 kHz to 400 GHz. The assessment of a network needs to be performed only in the frequency ranges where limits are def
21、ined. The emission limits set in this standard do not apply to the wanted emissions from embedded radio links within the network. The requirements have been selected so as to ensure that electromagnetic disturbances generated by a network, or parts thereof, operating normally do not exceed a level a
22、bove which radio and telecommunications apparatus or other apparatus cannot operate as intended. Fault conditions of the network are not taken into account. 2 Normative references The following referenced documents are indispensable for the application of this document.
