Foreword
This European Standard was prepared by SC 205A, Mains communicating systems, of Technical Committee
CENELEC TC 205, Home and Building Electronic Systems (HBES).
The text of the draft was submitted to the Unique Acceptance Procedure and was approved by CENELEC as
EN 50065-2-1 on 2001-12-04.
The following dates were fixed:
– latest date by which the EN has to be implemented
 at national level by publication of an identical
 national standard or by endorsement (dop) 2003-10-01
– latest date by which the national standards conflicting
 with the EN have to be withdrawn (dow) 2004-10- 01
This part of this standard defines limits and test methods for the immunity of mains communication
equipment and systems (MCES) operating in the range of frequencies from 95 kHz to 148,5 kHz and
intended for use in residential, commercial and light industrial environments. Immunity requirements
for similar equipment intended for operation in industrial environments are given in Part 2-2 of this
standard. Immunity requirements and tests applicable to Electricity Suppliers' equipment and
systems operating in the band 3 kHz to 95 kHz are given in Part 2-3.
These tests and limits represent essential electromagnetic compatibility and immunity requirements.
Correspondingly not all known disturbances have been included for testing purposes which have
been limited to those disturbances known to be critical for the operation of such equipment including
specific MCES disturbances such as conducted narrow band.
The immunity requirements have been selected to ensure an adequate level of immunity for MCES
in residential, commercial and light industrial environments. The levels do not however cover
extreme cases which may occur in any location but with an extremely low probability of occurrence.
NOTE  This standard closely follows EN 50082-1, the Generic Immunity Standard for the residential, commercial and light
industrial environment, from which much of the material is taken. However the nature of MCES is such that the
performance criteria given in clause 5 of this standard differ from those given in EN 50082-1, particularly regarding the
recovery of equipment following a disturbance. For clarity and completeness all the affected sections of EN 50082-1 are
therefore repeated in this part.
Annexes designated "normative" are part of the body of the standard.
In this standard, annex A is normative.

1 Scope
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
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 considered.
This standard gives limits which are applicable to products operating in residential, commercial and
light industrial environments. 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.
