Foreword
Add:
By Technical Board decision D124/183 the text of the International Standard IEC 60728-3:2005,
which is identical with EN 50083-3:2002, was approved by CENELEC as EN 60728-3 on
2005-09-13. As a consequence EN 50083-3:2002 is renumbered as EN 60728-3:2006.
The following date was fixed:
- latest date by which the existence of EN 60728-3
has to be announced at national level (doa) 2006-08-01

This European Standard was approved by CENELEC on 2001-10-01. 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.

Foreword
This European Standard was prepared by CENELEC Technical Committee TC 209, "Cable networks for
television signals, sound signals and interactive services" on the basis of EN 50083-3:1998 and the first
amendment to EN 50083-3.
The text of this first amendment was submitted to the Unique Acceptance Procedure and was approved by
CENELEC on 2001-10-01 to be published as part of a second edition of EN 50083-3.
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) 2002-10-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2004-10-01
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 and D are normative and Annexes E and F are informative.
