Foreword

The text of the International Standard IEC 60670-22:2003, prepared by SC 23B, Plugs,
socket-outlets and switches, of IEC TC 23, Electrical accessories, together with the common
modifications prepared by the Technical Committee CENELEC TC 23B, Switches for household
and similar fixed electrical installations, was submitted to the CENELEC Unique Acceptance
Procedure and approved on 2005-08-26.

However, due to some omissions in the text and taking into account the comments submitted by
National Committees during the voting period, the CLC/TC 23B Secretary asked BT not to ratify
the document. A new draft was submitted to the formal vote and was approved by CENELEC as
EN 60670-22 on 2006-07-01.

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) 2007-07-01

– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2009-07-01
This Part 22, which specifies particular requirements for connecting boxes and enclosures, is to
be used in conjunction with EN 60670-1:2005. This Part 22 supplements or modifies the
corresponding clauses of EN 60670-1. Where a particular clause or subclause of Part 1 is not
mentioned in this Part 22, that clause or subclause applies as far as is reasonable. Where this
Part 22 states “add”, “replace” or “delete”, the relevant text of Part 1 is to be adapted
accordingly.
Annexes ZA and ZB have been added by CENELEC.

BOXES AND ENCLOSURES FOR ELECTRICAL ACCESSORIES FOR
HOUSEHOLD AND SIMILAR FIXED ELECTRICAL INSTALLATIONS –
Part 22: Particular requirements for connecting boxes and enclosures
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this technical report may be the subject of
patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60670-22 has been prepared by subcommittee 23B: Plugs, socket-
outlets and switches, of IEC Technical Committee 23: Electrical accessories.
The text of this standard is based on the following documents:
FDIS Report on voting
23B/700/FDIS 23B/704/RVD
Full information on the voting for the approval of this document 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 shall be used in conjunction with IEC 60670-1. It lists the changes necessary
to convert that standard into a specific standard for connecting boxes and enclosures.
