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.

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

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 regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60309-4 has been prepared by subcommittee 23H: Plugs and
socket-outlets for industrial purposes, of IEC technical committee 23: Electrical accessories.
The text of this standard is based on the following documents:
FDIS Report on voting
23H/189/FDIS 23H/192/RVD

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

This standard is to be read in conjunction with IEC 60309-1 (1999) and IEC 60309-2 (1999).
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 IEC 60309 series, under the general title Plugs, socket-outlets and couplers for industrial
purposes comprises the following parts:
Part 1: General requirements
Part 2: Dimensional interchangeability requirements for pin and contact-tube accessories
Part 4: Switched socket-outlets and connectors with or without interlock
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
