Language in which you want to receive the document.


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 typetesting
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
This standard gives limits which are applicable to products operating in the public supply network,
operated by electricity utilities. The levels do not however cover extreme cases which may occur
in any location but with a low probability of occurrence. In special cases situations will arise where
the level of disturbances may exceed the levels specified in this standard e.g. where a hand-held
transmitter is used in proximity to an apparatus. In these instances special mitigation measures
may have to be employed.
It does not specify immunity between mains communication systems operating in the same band
(as defined in EN 50065-1) or immunity to signals originating from power line carrier systems
operating on high or medium voltage networks.
Safety considerations are not included in this standard.
