This European Standard was approved by CENELEC on 2006-09-12. 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, Cyprus, the Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland and the United Kingdom.

Foreword
The text of document CISPR/F/404/FDIS, future edition 5 of CISPR 14-1, prepared by CISPR SC F,
Interference relating to household appliances, tools, lighting equipment and similar apparatus, was
submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 55014-1 on
2006-09-12.
This European Standard supersedes EN 55014-1:2000 + A1:2001 + A2:2002.
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) 2007-06-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2009-09-01
This European Standard has been prepared under a mandate given to CENELEC by the European
Commission and the European Free Trade Association and covers essential requirements of EC
Directives 89/336/EEC and 2004/108/EC. See Annex ZZ.
Annexes ZA and ZZ have been added by CENELEC.
