This standard applies to electrical equipment using signals in the frequency range 95 kHz to 148,5
kHz to transmit or receive information on low voltage electrical systems, residential, commercial
and light industrial environments. In the case of equipment which includes functions other than the
transmission or reception of information on low voltage electrical supplies, this standard applies only to that part of the equipment intended for such transmission or reception of information. Other parts of the equipment shall comply with the immunity standard or standards relevant to the functions of those other parts. In the event of tests being specified in those other standards of a different severity and where the construction of the equipment is such that the functions cannot be tested separately, the higher severity shall apply to all affected functions.
The object of this standard is to limit mutual influence between mains communication equipment and systems (MCES) operating in different frequency bands as defined in EN 50065-1 and to contribute to ensuring Electromagnetic Compatibility in general. It specifies essential immunity requirements and
test methods, including those tests which are to be performed during type-testing of MCES on lowvoltage
installations, for electromagnetic interference in general and more specific interference coming
from other MCES. It therefore defines the immunity test requirements for apparatus in relation to
continuous and transient disturbances, both conducted and radiated, and electrostatic discharges.
Test requirements are specified for each port considered.
