1 Scope
This standard applies to electrical equipment using signals in the frequency range
3 kHz to 95 kHz to transmit or receive information on low voltage electrical systems,
for electricity suppliers and distributors. 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 low-voltage 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
