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.

Foreword
This standard has been prepared by the CENELEC technical subcommittee SC 205A, Mains
communication systems, of Technical Committee CENELEC TC 205, Home and Building Electronic
Systems (HBES) following the quinquennial review of EN 50065-1:1991 with the incorporation of
amendments A1:1992, A2:1995 and A3:1996.
The text of the draft was submitted to the Unique Acceptance Procedure and was approved by
CENELEC as EN 50065-1 on 2000-08-01.
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) 2002-02-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2003-04-01
Annexes designated "normative" are part of the body of the standard.
Annexes designated "informative" are given for information only.
In this standard, annexes A, B, C, D and E are normative and annex F is informative.
Modifications have been made to clause 5 to take account of false band-in-use detection.
Common-mode signalling in the 3 – 9 kHz sub-band has been deleted. Additions have also been
made to clause 6 in order to take account of three-phase signalling and an extra test for two
transmitters operating simultaneously has been added in subclause 8.5. Sub-divisions of the utility
and consumer bands are now referred to as sub-bands.
SC 205A has taken the advice of CENELEC BT regarding the conflict arising from the publication of
EN 55015:1996 and has therefore increased the threshold and lower transmit level for the consumer
band by +6 dB(μV).
References have been updated to include CISPR 16-1 and CISPR 16-2. Other changes have been
made to add clarity and bring the figures up to date.
EN 50065 consists of the following parts, under the general title: Signalling on low voltage electrical
installations in the frequency range 3 kHz to 148,5 kHz

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 supply system 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 signal modulation methods nor the coding methods nor functional features
(except those for the prevention of mutual interference).
Environmental requirements and tests are not included.
NOTE   In most countries the transmission of information is subject to regulation. 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
supply system where this would not otherwise be allowed.
The object of the standard is to limit mutual influence between signal 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.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other
publications. These normative references are cited at the appropriate places in the text and the
publications are listed hereafter. For dated references, subsequent amendments to or revisions of any
of these publications apply to this European Standard only when incorporated in it by amendment or
revision. For undated references the latest edition of the publication referred to applies (including
amendments).
