Foreword
The text of document 77A/503/FDIS, future edition 3 of IEC 61000-3-2, prepared by SC 77A, Low
frequency phenomena, of IEC TC 77, Electromagnetic compatibility, was submitted to the IEC-CENELEC
parallel vote and was approved by CENELEC as EN 61000-3-2 on 2006-02-01.
This European Standard supersedes EN 61000-3-2:2000 + A2:2005.
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) 2006-11-01
– latest date by which the national standards conflicting
(dow) 2009-02-01
with the EN have to be withdrawn
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 1999/5/EC. See Annex ZZ.
Annexes ZA and ZZ have been added by CENELEC.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee i
