This European Standard was approved by CENELEC on 2011-03-21. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Croatia,
Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania,

Foreword
This European Standard was prepared by the CENELEC technical subcommittee SC 205A, Mains
communication 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 50065-1 on 2011-03-21.
This European Standard supersedes EN 50065-1:2001 + A1:2010.
This revision aligns EN 50065-1 with CENELEC Guide 24; this has been done in particular in relation
to the responsibilities of parties involved by replacing with references to common application types
whilst not making technical changes to the standard. In addition the text on common-mode signalling
has been clarified and account taken of use of mains signalling in relation to the charging of electric
vehicles. Additional editorial changes have been made to clarify areas on which there have been
queries.
The following dates were fixed:
– latest date by which the revision has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2012-03-21

– latest date by which the national standards conflicting
with the amendment have to be withdrawn (dow) 2014-03-21

1 Scope
This standard applies to electrical equipment using signals in the frequency range 3 kHz to 148,5 kHz
to transmit information on low voltage electrical systems, either on the public electricity distribution
network or within installations in consumers’ premises.

It specifies the frequency bands allocated to the different applications, limits for the terminal output
voltage in the operating band and limits for conducted and radiated disturbance. It also gives the
methods of measurement.
It does not specify the modulation methods, the coding methods or functional features (except those
for the prevention of mutual interference).

Environmental requirements and tests are not included.

NOTE 1 Compliance with this standard does not imply permission to establish communication with locations outside
the consumer’s installation or with other consumers through the public electricity distribution network where this would not
otherwise be allowed.
The object of the standard is to limit mutual influence between transmission equipment in electrical
installations and between such equipment and other equipment. In addition this standard is intended to
limit interference caused by signal transmission equipment to sensitive electronic equipment. However,
complete freedom from such interference cannot be assured.

NOTE 2 Designers should consider signalling systems in conformance with this standard when determining immunity
for electrical equipment.
