Foreword
The text of document 23H/189/FDIS, future edition 1 of IEC 60309-4, prepared by SC 23H, Industrial plugs
and socket-outlets, of IEC TC 23, Electrical accessories, was submitted to the IEC-CENELEC parallel vote.
A draft amendment, containing some common modifications to the future IEC 60309-4, was prepared by
CENELEC BTWG 112-1, Improvement of EN 60309-1 and EN 60309-2, and was submitted to formal vote.
The combined texts were approved by CENELEC as EN 60309-4 on 2007-03-01.
This standard is to be read in conjunction with EN 60309-1:1999 + A1:2007 and EN 60309-2:1999 +
A1:2007.
Part 1 comprises clauses of a general character and the subsequent parts of the series deal with particular
types.
The clauses of the subsequent parts supplement or modify the corresponding clauses in Part 1. Where the
text of subsequent parts indicates an "addition" to or a "replacement" of the relevant requirement, test
specification or explanation of Part 1, these changes are made to the relevant text of Part 1, which then
becomes part of the standard. Where no change is necessary, the words "This clause of Part 1 is applicable"
are used.
Clauses, subclauses, figures, tables and notes which are additional to those in Part 1 are numbered starting
from 101.
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) 2008-03-01
– latest date by which the national standards conflicting
(dow) 2010-03-01
with the EN have to be withdrawn
Annexes ZA and ZB 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 interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and reg
